Subwoofer

I have two Rythmik subs and worked on a few areas for placement. Maybe you can have two quality subwoofers together facing out and place a tabletop on them. Make them a coffee table.  Might be a great conversation piece, Thinking out loud....

You left out the single BEST brand of subs to consider for two channel: REL.

Once I would have agreed. In twenty years, I’ve yet to hear decent demo of a REL product, even in $100k systems.

IMO, REL gave up engineering for bling. Most of their line lacks adequate controls to integrate properly.

Far too many conflate more with better.

@jpwarren58,

One sub can be used but definitely needs variable phase if you are limited with placement options. SVS is a great choice because of the adjustments available. It has a simple download which means you can tune it in from the comfort of your listening position via your cellphone.

In addition to phase you can also adjust volume, low pass filter, polarity, parametric EQ, room gain and presets.

You can also consider Rythmik or GR Research. there is no remote adjustment available so that needs to be done on the plate amp itself. These are servo controlled and perform superbly.

I do not understand those saying a single sub will not help. They can and do but if you just plonk a sub down where convenient then do not expect great results. You state room for one sub only and if that's the case then that's is that, but if you can squeeze another small sub in behind a couch or double as a side table or as stand for pot plant then the overall sound will improve far beyond expectations.

Even a small 8" sub will work. I use them as tuning devices and have used as small as 6.5" driver as a sub. What multi-subs do is smooth out the room response so even the little 6.5" unit that goes down to only 50Hz will help all nodes upwards from there. A 6'5 " driver in an 8" cube should not be too difficult to shoehorn in 'somewhere'

Multiple distributed subs give even, not accurate, bass at the LP.

All-Pass phase controls operate at only a single frequency with varying degrees of shift across the passband.

Hi jpwarren58...

After extensive search for a smaller dedicated studio deep bass solution under 80Hz, I discovered a larger, single, Direct Servo as my solution, replacing the two sealed subs I had been using.  My Rythmic L12 was $629 delivered and FULLY delivers at such a reasonable price.  Testing shows the Rythmic loading the room at 20Hz, which I never thought possible.  Don't be fooled by the price.  I was considering one of the higher end brands, but was well advised by experienced friends, near and far.  Tuneful, solid deep bass does not have to be costly and so contributes to all the frequencies in its execution.  

Best, jpwarren58.
