Subwoofer crossovers


I want to use my 2 JL113's with my 2 channel as well as my surround sound system. The JL's do not have an LFE input only L&R inputs. I think I need a crossover for the 2 channel system that I can shut down via remote so only the setting in the surround sound processor control the sub in theater mode. I use the right inputs for 2 channel stereo & the left inputs in a T configuration for mono with the surround system but the settings for 2 channel restrict the sub too much I think. I would like two differant crossover settings.
Any ideas or am I making this harder than it is.
Thanks for your input.

Edorr,
Sorry for the loooong delay in replying to you.
I saw no reply's after 2 week and thought this was a dead thread.

I am using my Sarastro II's full range. They have an 11 inch bass driver but I like how the JL's load the room and with Floyd music they add that very low fast bass. I crossover the JL's at 35Hz since they are being used with 2 channel. I would not want them at a much higher crossover since the Sarastro's sound great in full range.
I have tried a few subs and for 2 channel I prefer the JL's they are the fastest sub I have found I just wish it had an LFE input.

Yes I want the Meridian to handle the subs crossover & EQ's when in theater mode.

Martykl,
The NHT x-2 sound very interesting and the cost is minimal but is there a better unit available.
I like the fact it has an LFE input. Do you know if it overrides the stereo input?

This thread is getting interesting.
Thanks for the reply's
Would have been interesting but I never thought of it and never tried. Now I never will because I sold my my Verities and I am using Eidolon Visions.
Hevac1, we have a very similar approach in that I cross over at 35Hz and run mains at full range. I am also using the NHT crossover (as low pass filter only) and it works like a charm. It sums the LFE to the stereo signal. Obvioulsy, it does NOT apply the Xover settings to the LFE channel but adds the "full range" LFE signal (which is typically up to 80-120Hz). Marchand will custom build you a Crossover that sums LFE and stereo as well. I believe it was Marty who mentioned he preferred the cheaper NHT though.

Funny you sould mention Floyd music. Blew up my midrange drivers listening to shine on you crazy diamond last month.
Hevac, the LFE channel on the NHT is summed to the stereo channels. It does not override it. Works like a charm. It was the only device I could find that could so this. Marchand offered to custom build me a 3 in 2 out Xover for a lot more money. Unfortunately NHT no longer makes the x2 but they show up used occasionally.
