2 Subs, 1 LFE, 1 Enhancing Fronts

How do you plan to trick your bass manager into creating those two signals? I honestly can't think of how you'd set up the crossover.

Also, what problems are you referring to about two subs?

Go ********** and to the forums. Look under 'Subs in stereo...how to? thread. I got some interesting answers to a like question. I'll bump the thread to the top.

Oh, ok.

Assuming you can get them both level matched to each other and the speakers, it should sound/work fine. I can't think of why it wouldn't.

Yes, you certainly can do it. You would need to run your front L&R channels full range using a "large" setting on your receiver or processor and then use your bigger sub for the LFE.

I'm not experienced at all with HT set ups, but I can't see why it wouldn't work.

I know with my receiver, when the speakers are set to large all the normal bass frequencies are sent to the front speakers and the only thing going to the sub are the real low frequencies in the LFE channel. Using the high level inputs for the fronts and then a dedicated sub for the LFE channel sounds like a good idea to me.

If running the speakers off the S10s speaker level outputs, do you know what the high-pass of the S10 is in this instance? Even if your receiver doesn't have R/L pre-outs for connecting the S10, you can still run the front speakers full-range with both the sub and speakers connected to the receiver's speaker-level outputs. I was under the impression you didn't want to "cross" the front speakers. So, if your receiver has front L/R pre-outs, you actually have 3 choices of how to wire it. Either way, though, crossed ort full-range, doing what you are proposing is fine. Having 2 different subs if you used one for the front channels' bass and the other for LFE wouldn't really be an issue. It's when the same output is sent to both that it becomes an issue.

What is the sub's high-pass filter setting?

Does your receiver have R/L pre-outs? Just curious. Sounds like you are dead-set on crossing the speakers through the sub, so it's kind of a moot point as you'll have to use a speaker-level connection for that.

No. Either way you're going to have to set the front speakers to LARGE. I'm suggesting running the front speakers full-range off the receiver's speaker outputs and connecting the S10 to the L/R pre-outs (your LFE sub is going to be connected to the subwoofer pre-out). You'd then adjust the S10's variable low-pass (its "crossover" setting) to the low-end capability of your front speakers. The difference between that setup and connecting the front speakers to the S10s speaker-level outputs would be where the bass that's between the speakers' low-end capability and the sub's high-pass filter is reproduced; from the speakers versus the sub. There are probably advantages and disadvantages to both options.

That was the first thing I thought of too.

Say, a couple of SVS SB12's for the front subs and maybe a PB12 plus/2 for the LFE.

How big is your room? That's a lota bass!

Well, he/she already has an S10 that he/she wants to keep in the mix (I think). I think he/she just wants to add one bigger, more capable sub.

Well, you have an option of running the fronts crossed off of the front sub's (or subs') speaker-level outputs, in which case you would obviously use a speaker level connection to the subs.

As I pointed out, there IS a difference in the 2 choices. With one setup, the front speakers are run full-range and the sub is adjusted to fill in where the front speakers naturally roll-off. If you cross the front speakers off the sub's speaker level outputs, then the speakers (obviously) are not run full-range and the subs are adjusted to take over close to the sub's fixed high-pass filter (assuming it has one). There are advantages and disadvantages to both schemes.

And, what, are you now considering another S10?

Honestly, if running a separate "front" versus LFE sub is what you wish to do, I would just save your money up for the single bigger, badder, LFE sub. I'd run the S10, singly, off the receiver's front L/R pre-outs, and run the speakers full-range. In this scheme, the single S10 only has to reproduce bass below where the fronts naturally roll-off and it will also be less localizable as it is only reproducing the lower bass (as opposed to bass all the way up to somewhere near its high-pass).

For the time being run your more capable low-end sub (the S10 or the Polk) as your LFE sub and the other one as I describe.

Depends on what the question is.

There are many around here with a lot more posts than me. That I have so many is not anything I'm proud of, and is actually more indicative of the fact that I have "no life".

Well, actually you would need to know over what time period I had accumulated those posts, right? If you look at my public profile, it's 4.91 posts per day.
