If you set your crossovers at 80Hz, what's the problem? This whole line of questions is getting a bit confusing to me. Sounds like you don't really want traditional subs... more like mains with superlative bass response. Maybe you should look at something like 4x RBH T2s.
Many speakers have great response down to 80Hz. Many subs have great response up to 80Hz. I don't understand the problem.
The only problem ATM is I have to do a lot of owners manual reading on the PC and the system's in another room
to figure out how the heck to use my Denon DE-70 Eq, which currently is supplied signal via Tape 1 Out from my pre-amp
and feeds that processed signal back into Tape 1 Input on my pre-amp.
Sorry for the confusion, it was my misunderstanding of
the capacity, of the LFE circuit, which I was mirroring with the LFE channel.
I was not, distinguishing, betwixt the twain.
Now I understand the AVR can feed any frequency it has through this circuit
even though, the LFE channel is not recordable in such capacity. All new to me
I was thinking Rythmik was pulling wool over my eyes with LFE @ 200Hz
when the channel does not reach above 120Hz, confusion cleared, all can breathe a sigh of relief.
The patience is appreciated.
Now my mains, they do handle well below 80Hz with intoxicating accuracy.
I would not have dropped my savings and then some on them if they did not.
They cannot drive low frequencies with chest moving force though.
At such amplification, they discharge with a clicking sound, protecting the panels
and is the technology that brought the lifetime warranty with these speakers.
How many out there have speakers with a lifetime warranty when they purchased them?
Honestly, all I need to have a splendid experience with HT is a sub and 2 rears
and some of your alls help along the way while I am it. Thanks.
