Ohm Walsh Micro Talls: who's actually heard 'em?

Another way to look at it:

With Ohm Walsh if you have 8" drivers or larger in your speakers already being driven by a high power high current amp that will never come close to breaking a sweat (Class D or otherwise) you already have the equipment needed to do deep bass well with music. Its essentially the same driver and amp combo you get in a similar sized powered sub. No adjustments or eq needed if speakers set up well in the right sized matching room. The key is to match the right size OHMs to your room. Thats the OHM/JS model that nobody else offers, ie the same essential sound from all speakers in the line large to small when integrated into the room properly. Its hard to find quality speaker makers with affordable products that use 8" or larger bass drivers these days. Used to be common. Size and power  matters most when it comes to doing bass well. Multiple drivers help but add their own issues and I am not a fan. The fewer drivers needed to do the job right the better.  Good quality modern small bass drivers do a decent job though of getting more bass out of a smaller package by providing drivers capable of greater excursion than most common larger drivers of the past.   MicroWalsh does an impressive job with the bass I am told.  Totem and others always surprise me pleasantly with bigger sound than expected out of a small package.

it'll be very interesting to audition a set of Ohm speaker for the first time.
From what I have been told by John S, I would not be disappointed by selecting the cylinder shape if I can live with the aesthetics. Growing up, my dad had a pair of Bose 901 series 2s and I really liked the sound presentation from those speakers. just like Ohm speakers, the placement and distance from the wall and room orientation was very important. Despite of not being very detailed in the highs, I found the base and the mids to be more than adequate and they could handle as much power as you could throw at them. Immediately after learning about the Ohm speakers it reminded me of my dad and how he spent hours fiddling with the placement of the speakers and somehow I knew, I got to give these speakers a shot. it reminded me of my childhood memories and put a fat smile in my face.    

Good point that cabinet volume is a main factor in producing deep bass.   Smaller speakers  ("short" version of OHMs are much smaller cabs and more limited in bass extension) will always need help to deliver the lowest octaves.   Size matters when it comes to delivering extended bass.    Speakers must do EXPONENTIALLY more work as the frequency gets lower.   The laws of physics always apply.

The point of my using the Ohm 2.2000 SATs is why have a driver pushed to a frequency that causes distortion . The speakers sit on top of the subs and are now in acoustic suspension cabinets . I installed signal line caps in my amps to hi pass above 50 HZ . I find the Walsh driver sounds more refined this way . The second pair of subs evens out the bass response in the room . In this case more subs is less boom that is . Distributed bass  is the way to go
