Using PA Speakers In A Home "Audiophile" Application!

deep_333 OP: I went to the Rythmik website a little while ago because I was curious about those subs.  I had not heard of them.  They seem like good subs, particularly their servo technology.  They go pretty low in frequency too!  The only think that would keep me from buying them is that most of their models don't have balanced XLR inputs, other than that they have a lot more adjustments than most subs at that price. You should be content with those...

You can have all of it, volume, low bass and refinement. I do use QSC amps to drive my subwoofers but would never resort to  PA loudspeakers for home use. They are usually fatally colored. I can understand the attraction as commercial equipment is much less expensive. Getting the required output out of an audiophile system is not an easy trick either and can get expensive in a hurry.

You do not have to resort to PA equipment for "insane" bass. All you need is a lot of surface area and power. The minimum requirement for a small system in a 12 x 16 foot room is two 12" subwoofers. My system is on a 16 foot wall and I use eight 12" drivers in four enclosures. Each enclosure gets 2500 watts. They are also set up to form a line source or linear array like you see in stadium concerts. 

You can commute to work in a 3/4 ton longbed dually diesel pickup also, although most folks wouldn't really enjoy it. But if it needed to tow a 25 foot boat, that's a good choice. 

Same goes for speakers. I was in pro sound for many years, and have designed and worked with lots of pro drivers and horns. Great for their intended application, but most are definitely not HiFi. Exceptions noted for Altec 803-8G and 288 horn drivers and 515 woofers. But each of those components used probably cost near what those Yamaha's cost. 

I’ve read of Crown amps driving in-home hifi speakers to the owner’s taste, but not the reverse PA-hifi match.

The variable to consider for PA speakers in-home is not just how they are designed for power-over-fidelity, but what you’d be playing through them. You’ve heard PA speakers play live music, which is generally less dynamically compressed than highly manicured recorded studio music in pretty much any genre.
 

Have you listened to studio music on any PA kit? In my anecdotal take, I always thought the recorded popular tracks played while the techs set up the stage before a band sounded, well, very much less-than-great even before live shows that were fantastic. So the potential difference in compression (or other elements) between live vs. recorded music is likely no small factor in predicting how PA will work in-home.
