Obviously not quite accurate according to your link.

That being said, I really don't know if the HomeTheater measurements can be trusted either as the 68 Hz -3 dB point is surprisingly high and pretty far from the quoted 31 Hz. The 34 Hz figure I remember from Energy's web page before they removed the specs. I remember because I got the ESW-C8 sub as a bonus with the RC-70s and could not refrain from giggling seeing the C8 was rated at 36 Hz.

Seemed too low for the LCR and 10's so I bumped the LCR to 50 and the 10's to 60Hz. The whole setup is around 10Hz high than their rated specs which I figured would provide a clean transition to the sub. My EXL S10 sub isn't of the quality of the RC series and thought it should be used for just .1 duty and rounding out the bottom of the RC's.

So I cross my RC50's, RC-LCR, RC-10's and RC mini's at 80 Hz. I have two S10.3 subs (apartment) to handle the low end, sounds pretty good.

The mini's are nominally 80 Hz, but I know what you mean.

I bumped that to 100 Hz and feel that higher bass is better reproduced at high volumes with the subs than the RC-70s. Pops and thuds are livelier. With the duals localization is not a problem, but the 6.5 in woofers on the 70's are no match for the bigger woofers of honest subs.

Agreed. If you are fortunate enough to have two awesome subs I would set the crossover higher than 80Hz. The reason the "standard" recommendation isn't higher than 80Hz is purely do to localization issues, and if you have dual subs which smooth out the response and mitigate that problem, I would definitely go up to 100-120Hz. As you note, it really depends on the quality of the subs, but if you have excellent subs that play easily up to 100Hz+ with low distortion, there's a lot of benefit to doing so.

Music sounds great too with the subs, but your mileage may vary: electric bass can play as low as 40 Hz, so make sure your sub is appropriate for music before setting the crossover high. You don't want to trade shear output if it's for muddy instrumental bass. But I could not really get any sort of satisfying chest thump with the 70s alone, or if the subs are crossed over too low.

One thing I'd like to try is to run the dual subs in stereo, that is, incorporating them into the L and R channels. However since I lack speaker level inputs with those subs, the only way I see of doing this involves buying lots of new gear (AVR with pre outs, amp) and who knows, maybe I wouldn't like it anyway.

The EXL s10 isn't a bad little 10" sub. I have one of those.

The s10.3 is better which I have in my main room but the exl:s10 is pretty decent.
