Hey @John Schuermann
I'll dig out Floyd Toole's book again and look this up, but as I remember, he says the center channel should always be set to "small" because there is not much low end material there anyway. What are you using for your center channel and what is the crossover frequency?
I know there is plenty of low frequency material in surround channels (helicopters, bombs etc), so more low end extension is desirable.
If your system is using full range L/R and a sub (or multiple subs), how do you set your crossover? How much low frequency extension do you need from surround speakers if your subs are handling a lot of it?
I see 80 Hz as a crossover for a lot of system recommendations, but that seems high to me (low E string on a guitar). I think of bass more around 80 Hz down to 40 Hz (low E on bass guitar) and subsonic stuff below that.
If a main full range speaker is crossing over at 80 Hz with the sub, that frequency seems too high to me for both speakers. Obviously this depends on what main speakers and what subs.
Say we're talking about JBL M2's, Revel Salon2's etc paired with the right subs?
Say I wanted to add one sub (all that will fit in my living room) to my Revel F208's. What do you recommend? I'd love to get a JL Audio F112 (had a pair at work), but over my budget.
We watched "Arrival" a few nights ago and I felt the need for a sub. I have also been wanting to get a pair of Revel 763L's put in the ceiling to get 5.1 surround going again. Finally settled in the house and tired of living with just an L/C/R system. The F208's are great for 2 channel music listening and LCR is OK for TV, but Blu-Ray movies really need at least 5.1 which is all the room will accommodate.
Thanks for your insight.
