Seriously, I like it too much but if I had enough space I would have gone with a sub, that's for sure.
Sometimes ya gotta do what ya gotta do.
Big woofers in mains is better than bookshelf speakers, hell it's better than most floorstanders! and definitely better than no bass at-all
Behringer is a European company.
Being active, if you buy a miniDSP 10x10 or NX1000DSP amps (both of which aren't american products), then you don't have to worry about complex-impedance (just nominal), and then you'd have adjustable XO (rather than set in stone with money/time/materials), you'd also have delay for time-alignment and EQ for smoothing/cutting/boosting. You also wouldn't have to worry about the different driver sensitivities and level-matching them with analog components. (All solved by the DSP.)
The hurdles of the physical attributes of the drivers, of course, still remain... but that's always the case...
PA woofers are very efficient, they don't need much power; 80w should get decently loud.
Two 5 channel AVR's with pre-in's would be enough.
(Of course you'd still want to keep whatever existing processor you have now for the actual digital decoding and HDMI video switching, and master volume etc etc.)
But yeah, if you go passive/analog XO's then your job gets MUCH harder.
Nobody is born a speaker designer, they had to learn it the same way as anyone else.
Pretty much every STEM career is that way.
But yeah, if your goal is 25hz, then you'd probably want the best & biggest woofers you can manage to stuff into the box with sufficient power behind it. The low-end would preferably be powered with a pro-amp of some sort (or a high-powered HiFi amp, at least 500w @ 8-ohm just for the bottom-end alone.) If you want superb results that is...
Dual AVR's would definitely be a compromise etc.
Depends on your budget and knowledge.
More learning on your end may be required. (Barbie and Batteries not included, sold separately... hehe!
