Just finished up connecting my 950. I have the Def Tech 2000TL's for my fronts(has 15" subwoofer in each with choice of 2 low level rca in's - full range and LFE for the sub. Fronts are bi-amped 1 parasound 1500a for tweeters and 1 for midranges.Def Tech center with parasound 750a bridged,Def tech surrounds with another 1500a.Def Tech supercube 1.The supercube gets it signal fom the LFE output from the 950.Question..which would be the better...Making my fronts small and setting xover at 40 and connecting the rca to the LFE input of the Def Tech's (which I think would by pass the crossover in the Def tech's right?)to send the 40 straight to the sub. Or... Make front speakers large and connect rca to full range in and use the Def Tech's internal xover and make them true subs........Remember,I have the supercube 1 also...Boils down to, would my system sound better using my front stereo subs to run tighter and quicker by running the down to 40hz only or just making my entire system have 3 true subwoofers any input would be great thanks, Jeff

i would feed the supercube with the lfe output from the 950, the front towers from the front right and left outpus (need to split before going to amps I presume). this setup would have the fronts set to large (i.e. full range for their respective channel) and all lfe going to the sub.

First, I'll offer a couple of related threads: DEF TECH BP2000 and deftech powertowers . In all likelihood, the best bet is to let the subs in the 2000's act as stereo subs handling the low frequency for the mains while the Supercube covers the LFE and low frequency data crossed over from center and surrounds.

so we are in agreement!

Yep, that we are. As I recall, it's been known to happen.

gonk,I read in the 2 links you gave me(thanks!)that the xover in my tech 2000's are set at 80hz.Is this true,not very low. I read the manual...it doesnt say. Also, I think I'll try both ways as far as either using the 15" woofers as stereo subs or setting front speakers to small and setting the 950's xover at 40 for the fronts.Getting back to my question.... if I hook up to my 2000's via low level LFE "in" does that by-pass the xover that is in the tower? In turn,which would make the front speakers have the 40 hz xover per the 950?

Also, as I watched a movie tonight for the first time after hooking up the new 950 I heard very low muffled chirping sounds coming from my brand new supercube 1 (not all the time though,about 3 times during the whole 3 hour movie,lasting about 5 seconds each time,that I heard during quiet passages in the movie) could be doing it more and cant hear it.Has anybody heard of this happening? Suggestions on what it could be? Thanks.

Also,also,When I was cal. the speaker volumes,I couldnt get my center down to match my other speakers. I have gain controls on all my parasound amps can I adjust this control on my center amp(which has been bridged)? Never did quite understand how you use a gain control the parasound manual says I should leave it all the way up to have THX standards If so what is the procedure. Do I leave it at the default setting in the menu of the 950 and go straight to adjusting the gain on my center amp?

You'll enjoy better signal-to-noise ratio if you send the amp a relatively hot signal (as long as you don't clip anything) and turn the amp gain down to suit your needs. The gain control on the amp is basically an attenuator; it has no effect on the maximum power capabilities of the amp. It's best to optimize the levels of the rest of your system (unity gain) and then turn the amp gains (volume) up only as far as you need to. Turn the gain all the way up on the amp can be nasty. (Hum, buzz, and hiss..etc)

Tighter and quicker has nothing to do with stereo sub set up or not. It all depends on your driver's characteristics. The TS parameter usually will tell you the best. A driver with very high BL value will usually have a good control over the cone. But, I am afraid you will never know that since you purchased a ready-made speaker. Ask the manufacture, they might tell you.
