Thanks! They are as spread out as can be, but the soundstage sounds GREAT!

I just recently purchased an Emotiva XPA-3 to power the towers and the center channel, which really helped and made a difference at louder listening levels, especially in regards to dynamic range.

I'd be curious to see how that room measures.

I got a similar issue...while my subs aren't both up front, they ain't where the 'woofer crawl tells me to put them either!

Set up #1: EMP e5ti, e5Ci, and EMP e5Bi surrounds, Outlaw LFM1 Plus sub, EMP 10i10i sub
Set up #2: Def Tech SM450, CLR2002, SLS Qline surrounds and Klipsch 12wD sub

Sub woofer crawl is for a single position, single sub. Multiple subs attempt to level out the bass across all seats, not to increase bass.

Ideal is 4 subs in a cross fblr then 2 subs lr mid wall, lastly 2 subs, front/back opposing corners. The subs will act as bass traps for the opposing sub.

Listen to the avrant podcast if you want to hear about sub setup.

No, not really. Subwoofer crawl works well for 2 subs within a room, with more subs it becomes less effective. Caveat: If the room is very large, the crawl with 3 or more can make a big difference.

This depends on placement. Stacked, as in Viper's case, will typically produce 3 - 6dB more output at a location - Which may not be the MLP. But the general use for multiple subs is to smooth the bass response across multiple seating positions, yes, by having them placed strategically about the room.

I am by no means an expert on this subject, but as I understand it ideal positions within any given room depends heavily on the room itself, and the listening position(s). Crazy amounts of information on this can be found within the Earl Geddes' writeup (very short version: https://mehlau.net/audio/multisub_geddes/) as well as AVS's own DIY Speakers and Subs subforum, and Bill Fitzmaurice's work (he posts quite a bit here on AVS). A terrific (if not horrifying to a beginner) rundown on integrating multiple subs was done by mtg90: mtg90’s multiple subwoofers + mains integration How To thread

As Soulburner mentioned, without measurements (and the sub crawl), sub placement is pretty much shooting in the dark. However, in the end it all comes down to how you like the sound, not how your graphs look.
