Try AVSFORUM too.
But, in theory and what I've seen on subwoofers few cut off at low Hz. I've seen some that have cut off filters above some Hz but for sub 20Hz let's say there's no cutoff filter. I see the speaker move.
BUT http://carltonbale.com/ultimate-home-theater-subwoofer-bass/ kicks in the deal that for 20Hz you need "For a full horn subwoofer to reach 20 Hz, the horn length has to be 30 feet." then they get into half and quarter wave design methods.
At that link, AVSFORUM is noted again.
can you please tell me how does the chane sbe 118 subwoofer compare to the svs pb16 ultra subwoofer in terms of performance and lowest sub frequency
and how low in frequecy possible does the sbe 118 subwoofer go
i want to use your 3600 amplifier with 4 chane sbe 118 subs i want to connect it to a denon 4400
with a marantz 7025 amp as well
i want to connect it with the high frequencies of the left and right speakers of the jbl 590 speakers bi wired
with the marantz 7025
and the low frequecies of the jbl 590 frequencies to the emotiva xpa2 gen3
amp then both amps connectesd to the denon 4400
and the 4 chane sbe 118 subwoofers connected to the 3600 as well
would this work and do i have all the connections to do all this
and would the subs work well with the jbl 590 front speakers
with the jbl 580 centre
with the 2 svs ultra towers as rears
and 2 jbl 580 as additional rears
and 4 svs prime elevations as atmos height speakers
with blue jeans speakers cables and using either 7 marantz a700 monoblocks
or the 7 outlaw 2200 monoblocks for the 7 other speakers to enhance them
