Looking for a new Subwoofer
Four cabinet Bass Array systems go low and provide an unparalleled room lock while using less power and EQ with minimal location restrictions. Most if not all -3dB subwoofers require standing wave bass mode room (crawl test) positions to providin... 
Are REL the most Musical Subs?
@lono24 There are plenty of other great subs with great specs (especially for theater applications), if you are chasing lab measurements. FWIW, I used to be a Velodyne fanatic, but have changed to REL when I got intrigued by their approach.  lo... 
Are REL the most Musical Subs?
@jim2 I can't imagine I would ever go back to non-servo tech for bass. Purchased my first servo sub from Jonas Miller and Ken Kreisel at their Wilshire Blvd. store 1978. In 1983 the Velodyne ULD-18 provided more control far less distortion and ... 
Anyone else excited for this Borresen subwoofer?!!!
@mijostyn Are all your sources digitized?  @phusis I had one of Tom's tinnitus inducing Tech 7 ServoDrive belt drive horns with the band for a few weeks. Brought it in the house and ran the source through the Velodyne's Rap EQ preset, OMG! I hat...

"Subwoofer speed"? Can't wait to see the speed o meter measurements.  Their design reminds me of a small version of the Danley Labs Matterhorn semi truck trailer subwoofer project they made some time ago. https://www.youtube.com/watch?v=o36Kp6ve... 
Worth repairing a Velodyne ULD-12 from the 90's?
Your Father sounds like he had it going on, nice. Market value? Working, its still a potent little model. Without a need for it your on your own. Not much trouble shooting information in the ULD manual. http://velodyneacoustics.com/pdf/uld/ULD-... 
Are REL the most Musical Subs?
All REL are -6dB@ their lowest frequency and were termed  "SUB-BASS SYSTEMS" by the initialed developer manufacturer Richard Edmund Lord on his Operating Instructions. Regardless of what their product is called today simply matching the REL volum... 
Subwoofer Advice
+ big_greg, well said. mijostyn continues to take the time to share a great deal of his practical experience gained from his interesting system and room relationship. Also well done. I have great admiration when it comes to his immaculately dust ... 
My list of compact subs with room correction.
@russ69 Sounds like you got rid of it so just an FYI. On page 38 of Velodyne’s SMS-1 manual the subject of room equalization is a bit confusing in its black hole description of standing waves. DSP, room optimization and a -3dB subwoofer itself ca... 
Subwoofers and Seating Position for Klipsch Forte iv's
@deep_333   Do you have a measurement mic? REW? If not, you may crawling for a long while and still probably mess something up. I found the opposite far more practical. With the sub located at the listening position (as per Velodyne DD Optimizati... 
Where Do I Go from Here?
With that budget and before you sell those difficult to outperform Studio's, I would insist on an in home comparative audition.   As consumers we simply do not have the years of variety listening ability and experience that some audio professiona... 
Small footprint subwoofer
highend64    'As far as the position of the Hsu sub, yes it is in a near null position by not quite. That is why it is off centered to compensate the difference. I have the tools to do measurements so finding the best place for the sub is not a pr... 
Small footprint subwoofer
highend64  I apologize for not being more helpful. While you moved the HSU slightly and it measured differently is not how to position a subwoofer. The most effortless, quickest and practical way to find your rooms standing wave bass modes must b... 
Small footprint subwoofer
highend64  The two Double Basses I own the open E string tunes to just over 41Hz. Regardless, its how the environment they're played in or how the producer wants it to sound that a -3dB subwoofer is able to convey the delicate sub sonics. Unlike t... 
ReL Subs: High Level or Low Level connection
mijostyn   Your's was an informative ah-ha post for me. Hacks that we are, despite the systems star grounding we assumed a grounding issue but were very hesitant to lift the amplifier ground. The three of us could hear a noticeable issue when th...
