Subwoofer meshes well with 2-channel?


I hadn't really given it much thought before, but will a sub work well with a 2-channel system (when reproducing music) or does it just muddy things up? I have full-range speakers (Tyler Linbrook Sig's) that go down to 30hz or so, and have 2 7" Seas drivers. I had considered getting bigger speakers that have more drivers, but this would be a more economical option, rather than getting some huge 300lb speaker that requires a crate to ship on.

If this the case, is there a particular reason that huge speakers are common, vs. a smaller speaker and subwoofer combo?

Dawg, I high-passed my mains (connected passive filter in-line at amp from pre connection) with 85Hz filters from ACI (they have balanced and unbalanced) and adjusted my two ACI Titan (powered) subs to fill in the LFs. Works fantastic! Easy to do with Radio Shack SPL meter (cheap) and test tone CD. Very full, balanced sound to 20Hz. And two energize my room better than one.

Did the ACI filters degrade the sound? I have some 65 hz passive filters from ACI but have been reluctant to use them.
No degradation detected at all. As a matter of fact, high-passing my mains (two 6" woofs each running uninhibited otherwise) cleaned up the sound dramatically. The only "negative" was a -3db in volume, which, for me, wasn't a negative since I have a volume control on my pre - I just turn it up a little higher now. (This does not use more amp power.) I started with the 65Hz filters when I had only one sub but ended up with the 85Hz filters once I got a second sub. Best $35(?) I ever spent in audio.
Johnc5 - Of course, you'll have to reintegrate your sub(s) if you have any after installing the filters.
