Price Match Guarantee!We guarantee to match anyprice from authorized dealers In the tradition of most of Velodyne's upper tier subwoofer products, the DD-15+ is a single driver sealed active servo design. The DD-15+ sports a 15" driver. The servo feedback mechanism compares the input signal to the amplifier versus the cone motion and helps reduce distortion, which often plagues subwoofers in small enclosures. The amplifier in the DD-15+ features an overload protection circuitry. The driver is digitally controlled with a current limiting driver servo to reduce distortion by preventing clipping and over-excursion. The amplifier section has thermal protection as well as protection against excessive voltage drops. Velodyne is all about maximizing output and minimizing distortion in the smallest possible enclosure size. This takes two things: a driver with lots of excursion and an amplifier with lots of power. The DD-15+ has both in droves. This fact is quite apparent when taking a closer look at the new DD+ driver. DD-15+ driver advantages over the original DD-15 Driver: Magnet motor structure weight increased from 24lbs to 39.7lbs Basket design went from conventional design to underhung design Increased electrical and magnetic linearity with greater Xmax, higher compliance (Cms) and 20-30% increase in Bl while maintaining the same Mass (Mms) and resistance (DCR) which dropped the resonant frequency (Fs) Driver material upgraded from Kevlar reinforced resign to fiberglass Rohacell laminate The benefit of an underhung designed motor structure allows the usage of a shorter voice coil compared to the top plate of the motor structure. This is done in order to reduce harmonic distortion, since voice coil is held in a constant magnetic field throughout the entire XMAX of the driver. This is quite an expensive driver type, but it shows how Velodyne spared no expense to ensure the lowest possible distortion out of their flagship DD+ series of products. Velodyne claims their DD+ line of subs have between 4-5dB more output for each comparable model to the original DD series of subs. Based on the driver differences between the two products (and the fact that the new DD-15+ box volume has increased nearly 25%) we have little reason to doubt this claim, but of course we measured to confirm the results as you will read later in this review.The DD-15+ is not video-shielded but this is an ever-diminishing problem in this era of post-CRT display technologies. Inside View of the DD-15 (left pic) & DD-15+ (right pic)Inside the box, we see some big differences between the original DD-15 and DD-15+ subs. The DD-15 has no internal bracing baffles whereas the DD-15+ has a clearly implemented baffle brace that is also bolted to the heavy driver for further reinforcement. A quick knuckle tap on both cabinets reveals the DD-15+ produces a solid thud while the DD-15 has a more hollow or resonant sound character. This alone in my opinion is a marked improvement that I am glad to see in a product of this caliber.Velodyne DD-15+ AmplifierThe Velodyne DD-15+ boasts a digitally controlled class D amplifier section (up to 95% claimed efficiency at full load) that is said to deliver 1250 watts rms power and 3000 watts dynamic power (same as the original DD-15). The amplifier, which is separated into two sections, occupies the entire back plate. One board is dedicated to the power supply supporting the transformer and main fuses. The second tiered board supports the preamp functions and six power supply capacitors. There is a small heat sink to the side of the capacitors while the majority of the circuitry lives under a grilled metal housing to reduce radiated RFI noise inherent in high frequency switching amp designs. Based on the power consumption rating of 12 amperes listed on the back of the unit at the standard 120 volts we get a power rating of P = 0.95(12A * 120V) = 1368 watts which exceeds the 1250 watt power rating that with a slo-blow fuse leaves little to suspect the rated power of the amplifier.Velodyne DD-15+ Grille Cover (notice no flimsy plastic here)The build quality of the Velodyne DD+ series of subs is obviously raised considerably compared to their predecessors, not only in driver mechanics and cabinetry, but in the actual grille cover, too. I don't think I've ever encountered a sturdier or heavier grille cover on a subwoofer before. The grille is actually constructed of 1" thick MDF (no flimsy plastic) and finished and stained satin black with cloth wrapped on the outside which looks and feels great. It looks very clean installed on the sub since it recesses into the front baffle for a nice flush look. Velodyne knows the driver in these subs have a lot of stroke and require not only a rigid cabinet but a grille cover as well. You don't typically get this type of build quality in less costly subwoofers - which, in my mind, helps partly justify its rather hefty price tag. Backpanel view of DD-15 (left pic)& DD-15+(right pic)What is most interesting is the original DD-15 and DD-18 subs were THX Ultra2 certified. The new DD+ replacements no longer carry the THX logo or certification. This is an obvious cost cutting savings for a company that can undoubtedly pass THX spec without the sheet of paper by now. As indicated in our measurements, the DD-15+ walks all over the DD-15 and you don't need a THX stamp of approval to acknowledge it. We've noticed a trend with numerous manufacturers that THX certify their first generation of new products but not the successor products. This allows the manufacturers to offer a next generation product that exceeds the performance of the original while keeping the retail price the same (or sometimes less) by not expending margin for the THX stamp of approval. Velodyne DD-15+ Backpanel ViewLike the DD-15, the DD-15+ has one of the most comprehensive connection panels we've ever seen on a subwoofer. The DD-15+ takes it up a few notches with the inclusion of all balanced connectors (nice touch) and an Ethernet connection for firmware updates. The only connections missing are speaker level outputs, but I can't imagine anyone buying a sub of this caliber would be hooking it up speaker level and using the bass management of the sub for their satellite speakers no less. Velodyne DD-15+ Frontpanel View (with grille removed)The front of the DD15+ is where the microphone and USB connections are made to run auto setup and self-EQ options. There are also a volume and crossover potentiometers adjustable in 1dB and 1Hz increments, respectively. Velodyne claims the volume adjustments are actually .4 to .5dB incremental depending on the actual output level setting. Gone is the backlit Velodyne logo that illuminated anytime a DD series sub was powered up. I really missed this feature and wish Velodyne would have at least incorporated some indication when the DD+ sub goes active other than simply listening for it (although it's hard to miss). This is especially handy in situations where users are employing multiple subs in their theater room and want to give a quick spot-check around the room to ensure all of the subs are powered on before playing a demo to a first-time listener.

Monitor Audio ASW-210 Very Good Condition, One Owner, 2...
I used this subwoofer together with Monitor Audio Silver 9i. Awesome bass (see reviews below). The speaker is "like new" condition (see pics of all sides), with only one very small indentation in bottom woofer, which does not affect performance. Specs: Power: 200 watt Woofer: Two 10" Gold Aluminum Magnesium active drivers Magnesium driver Low pass: 40 Hz -140 Hz Phase Adjustment: 0 - 180° Frequency response: 25 Hz -140 Hz ± 3 dB SPL: 115dB Max Weight: 55 lbs. Finish: Black System Type: Front Ported Bass Reflex Dimensions (HWD) 20 ¼" x 14 ¾" x 14 ¾" MSRP: $999 Audio Review.com Review of Monitor Audio ASW-210 Date Reviewed: February 15, 2004Bottom Line: I'm not sure how loud and low the previous reviewers play the ASW210, but I've yet to bottom it out. I've tried bass heavy movies at reasonably high volume like U-571, Finding Nemo (in the whale, glass knocking) and so far the ASW210 has handled them very well. No bottoming out, rattling or port noise heard. Maybe it didn't go infrasonic-low, but the ASW210's specs did indicate that lowest frequency is at 25hz. So, you can't expect it to go much lower than that, right? Yes, there are many movies that are real sub-killers these days but even with a limit at 25hz, the ASW210 still managed to perform admirably. Bass is fast, tight and well controlled. The sub has performed very well for both movies and music. One thing is once I got the ASW210, all other speakers suddenly seem to be performing better. Now my movies can go louder and with more clarity and I did not experience fatigue playing at reasonably higher volumes. The subs build quality is very good. The 2 gold 10" drivers really make this sub a very good looking one too. I managed to get a pre-owned (only half-a-year old) unit that was in excellent condition at a very good price - so I'm very happy with it.

Velodyne DD-12 Black, used
Works great, but the backlight behind the front panel doesn't work. I tried to get it replaced, but it didn't seem easy/possible, so I just live without this light that indicates the unit is on. This item works great, with that one exception. I do not know of any cosmetic issues/flaws, but I am rating it as Very Good just be conservative. Comes in the original double-boxed cartons, with all original accessories (remote, manual, and the equalization kit including microphone and cable. I will include a power cord, although I doubt is is the original power cord (standard IEC power cord). http://velodyne.com/pdf/digitaldrive/dd-12_details.pdfhttp://velodyne.com/pdf/digitaldrive/dd_manual_revg.pdfhttp://velodyne.com/pdf/digitaldrive/dd_series_brochure.pdf

Pioneer Subwoofer Mods Pioneer SW-8MK2 Modification to ...
In the words of The Absolute Sound’s Robert Harley, Stereo Dave's Audio Alternative is a “small, but passionate” (TAS #229, Feb 2007) audio company in Gresham, OR (near Portland). We make our own custom-made, crossoverless single-driver speakers (that really work), subwoofers, interconnects, and speaker cables. We have also been modifying audio components of different makes and models for more than a decade. We became interested in modifying these Andrew Jones designed subwoofers / speakers, as we saw they were highly reviewed and quite inexpensive. The speakers (SP-BS22-LR) were so exceptional sounding that we were very curious to try out the subwoofer. Reviews can be found in "The Absolute Sound "and "Stereophile" for these speakers (SP-BS22-LR). The subwoofer (SW-8MK2) was just recently reviewed by "Home Theater Review," a very reputable online review site. As we tested out the speakers, we found them to be quite good for the price and very balanced. When we opened up the speakers, we found them to be well designed with better than average cabinet engineering. For the price point, they were exceptional and sounded better than many other much more expensive speakers on the market. The sub is almost more exceptional. While they don't have quite the amount of "slam" or impact of other higher priced speakers, they are quite amazing with the 8 inch subwoofer SW-8MK2 pioneer manufactures from the same series, which is sold separatley (priced at $156 stock with free shipping - NOW ON SALE FOR $119 from Best Buy). The Pioneer SW-8MK2 Andrew Jones Designed 100-Watt Powered Subwoofer. When modified, the suwbwoofer gave the sound heft and richness. A recent customer was quite taken aback by now impressive they were and how they sounded. Admittedly, it does not have the very bottem octave of bass depth that our reference system has, but it does have slam, impact and other audiophile qualities. The modified subwoofer was also a surprisingly good LFE sub; much more so than we anticipated. We tested it out on "Star Trek: Into the Darkness' opening scene. The room was less than ideal, with a number of hallways, and the sub being placed a far distance away from the main av system. We were quite taken aback by the powerfull, deep slamming bass it produced for the LFE channel, especially for the size. As this was playing, the customer's were both shocked at how much bass came out of the small modified 8 inch subwoofer. When modified, it is about 80 percent of our reference system. For the price, they really are quite a find when they are modified. The Modified Pioneer SW-8MK2 Subwoofer sells for $356 modified (Unmodified unit sells for $156 each on Amazon currently - ON SALE FOR $119 FROM BEST BUY). The modification price inlcudes free shipping and handling when we ship the item back to you in the continental USA. If you have the subwoofer currently, feel free to ship them to us to have them modified as well. The modification price on the subwoofer, if it is shipped to us, is $200, which includes free shipping and handling back to you (price for unmodified SW8MK2 is $156 free shipping and handling). There is a new Andrew Jones designed subwoofer that is 10 inches (Pioneer Elite SW-E10), that we modify as well. The modification provides the same benefit to the 10 inch subwoofer as it does to the 8 inch, only more so, as it is a larger driver with a more power amplifier. FREE SHIPPING AND HANDLING BACK TO YOU IS INCLUDED IN THE MODIFICATION PRICE We also modify all makes and models of receivers, players and other pieces. Here are a few excerpts of the new review online on Home Theater Review by Terry London: "Excited to contact Sean Scoggin of Stereo Dave's Audio Alternative, I called him to discuss what his modifications were to the Pioneer SW-8MK2 and discovered that they use a proprietary method to influence and speed up the electron flow of the subwoofer's amplifier. Modifying the driver allows the subwoofer to move faster and have better freedom in its excursions for accuracy and speed in its ability to track the low frequencies it is replicating. All the modifications successfully work to quicken the subwoofer and increase its bandwidth/frequency range, making the subwoofer sound faster, more powerful, and deeper while still maintaining bass texture and detail. When I got the pair of modified SW-8MK2 subwoofers from Sean, I set them up exactly as the stock pair had been set up in my system. To my amazement, I heard the sonic improvements in the first few moments of auditioning the modified pair. The modified SW-8MK2 subwoofers truly were much faster and more dynamic, they created deeper/flatter bass extension, and they had more accurate tonality in a natural way, making their integration with my Mandolins even more seamless. With this modification, the SW-8MK2 significantly outperformed my T-7. ...The modified version of the Pioneer SW-8MK2 subwoofer takes this already excellent performing unit to another sonic level across the board in speed, power, bass extension, and accurate bass tonality. ...if you choose to have the SW-8MK2 modification done by Sean Scoggin's company for an additional $150 (plus shipping and handling costs), you have a subwoofer that performs at a sonic level that normally would cost you at least a couple thousand dollars. " Stereo Dave's Audio Alternative Customer Feedback Every once in a while, we get emails back from customers that take the time to let us know how they liked their modified units. Below is one of the recent ones referring to a Modified Pioneer Player: "Hi Sean I had a chance to do some listening to the modified Oppo (103) player and was not prepared for the difference in sound I heard compared to the stock unit. Most noticeably, the sound stage has hugely expanded, which, upon first hearing, made me shake my head in disbelief. The location of the instruments is more precise and the low end frequency much more palpable. There is just "more" of everything in the presentation of the music. I have had many mods done to my audio equipment over the years and your mod ranks near the top of the list for the degree for sonic improvement for the investment. You mod is a huge improvement over the already fine stock unit. Thanks a million!" Mark from California Sean, I love the sound of the modified player. I have it hooked up using the analog inputs. I didn’t change anything in my set up except to swap players. It sounds way different than the Denon 2900: better in every way. The biggest difference for me was how the player made the speakers disappear. Does that make sense? Music sounded ok with the Denon, but it was just a source to play cd’s, nothing special. I listen to all types of music: swing music from the 30’s and 40’s, Latin or Salsa music for dancing, smooth jazz for night time listening, 70’s soft rock and classic rock. I’m all over the board. The player did make a difference in the presentation of the music. One example is the bass: the Denon’s bass was rather bloated. I didn’t notice this until i had the chance to listen to the Pioneer. The Pioneer’s bass was more natural. The bass blended better with the music and didn’t sound like it was “in your face”. The vocals sound great as well. Even my 14 year old commented on how the voices sounded smoother and more natural. He even mentioned that it sounded like there was a center channel speaker hidden somewhere for the voices to come out of and “float in the air”. Nope, just my Tekton Lore speakers. The Pioneer has taken my listening enjoyment to a new level. Kudos to whoever designed the mod because it does sound awesome! Thank you, Javier Here is feedback from one of our modified HK 990 units from a customer: Sean, Forgive the late feedback, but just to say I absolutely love the amp. This is just the sound I was looking for. Thank you, Andrew Australia

Revel B15a Cherry
Up for sale I have a clients Revel B15a Subwoofer in Cherry. The subwoofer was originally installed in the clients theater but when they moved (after a divorce) the wife took it and put it into her small media room. She doesn't like how it looks, but anyone who knows the B15a knows how good it sounds!!! The subwoofer is in good condition with only some small surface scratches on the top and one side and a couple small marks on the other side. The sub itself presents itself well and if I didn't already have one in the light wood with the matching F30s I would keep it myself and give her a credit. The subwoofer comes with what is shown and I will also include the room equalization software. From 2000-2002 worked for Madrigal and these subwoofers always impressed me for the price. If you want help with using the tuning software I have a good deal of experience with these subs as I have sold and adjusted a LOT of them over the years and can help you. The subwoofer will ship from CT and the buyer is responsible for pickup or shipping. The subwoofer is currently at the clients residence and I will make all necessary arrangements to pick it up and safely pack the subwoofer for you. It weighs 105lbs so it will likely need to be palleted and shipped freight. If you are within driving distance it might be a good idea to take a ride. The client is willing to talk about offers on this sub, but I do need to communicate through her so there may be a slight delay.
