I looked over the website but didn't see if any of the subs came with a high pass output?

The subs are hooked up as a mono group but claibrated in pairs. I did fool around with individual settings, but the pairs are symmetric so tweaking them as pairs worked fine. The second rear sub is slaved off the first in the final configuration.

More pictures showing final (for now) system response over on the XMC-1 thread: Emotiva XMC-1 Owners Only Thread I shall note that four subs allowed me to really dial in the overall system response and integration with the mains so I have the best sound I have had in years. Should have added them a while back but other things kept coming up.

I adjusted pre/pro gain so the plots mostly overlie; I did get a large boost in output by adding the rear pair (do not need it, though).

Now of course I wish I had XLR2 amps on my first pair of F12's but everything is working OK as-is. I was worried about ground loops sice the rear subs are on a totally differnt circuit but no problems (whether due to the balanced XLR connections or just luck I could not say). I really like having a trigger input on the subs! Saved me having to get a couple more X10 appliance modules to switch them on and off.

It was a lot of work (had a couple of vacation days I had to take; this used a substantial portion of them) but I am happy with the results. Some sonic issues I've been hearing seem gone now, probably due to a more even sound field and smoother frequency response for the whole system.

Happy, yes I am! Thanks Brian and Enrico! - Don
WOW.... -6dB @ 7Hz.. That's really impressive, Don!!! Good job

The F12 with A370PEQ amp comes with HPF out @ 80Hz. Also our XLR2 amp has HPF out (mono) via XLR fixed at 80Hz as well.

I'm in the market for a sub, but not sure which model I'd be happier with. I'm thinking either the LV12R or the F12. I'd be using the sub more for HT than music, say 80/20 split. I don't consider myself a bass head; I've never cared much about the room shaking while watching a movie. But I do like tight bass when listening to music.

My current speakers are Paradigm Studio 60's version 2, but in the next year or two I plan on upgrading. At this time, the Ascend Sierra Tower are at the top of my list.

My listening room (aka "the basement") is 14 x 27 feet with a drop ceiling 6.66 feet high. About 2517 cubic feet.

I'm not concerned about the price difference between the LV12R and the F12, but I'd be reluctant to spend more.

I'd welcome any suggestions as to which model (or any other) people may think I'd be happier with.
Thanks.

In a room like that I would also consider the L22 which has more output than both, the LV12R and the F12.
