where do you cross over your ht setup

John Z, I do exactly what you say not to, and I am not 100% satisfied with how my Sub sounds. Although 100% satisfied with audio is an oxymoron, especially with Subs. Anywho, can you or someone else, explain the technical reason the two filters will interact poorly.

I am going to tinker with cabling tonight and I intend to try your recommendations, but I would like a technical foundation on which to ponder. Thanks in advance.

For lack of a better word, I fiddled around with the setup last night. Changing around the settings for large and small, Xovers (5hz increments), and the Sub Xover bypass.

The jury is out on HT, but, the bass did improve with multi-channel music when I, set only the rear speakers to "small," selected 80hz as the Xover point, and bypassed the Subs internal Xover.

I am still curious about the technicalities. I would imagine that like most everything else in audio, less is more. A signal running through two Xovers is unnecessary and doubles the potential to degrade the sound quality. Not to mention slope differential (db per octave) or overlap.

Thanks for the tips.

Eldartford, that makes sense. I can see were two Xovers set at different points with different slopes would interact and possibly get messy. Thanks much for the explanation of Xovers, I didnt know that.

Exertfluffer, thanks so much for the info. Today I tried running the LFE straight from the processor to the Sub. Which, in effect, bypassed the external controls/crossover. It didnt make any difference. But, when I choose, and I usually dont, to run my Sub when I listen to 2 channel bypass, I will need the Xover since my Processor only outputs a full range Subout (in that mode).

I have watched a couple of movies since I made the changes mentioned above. It seiously improved the impact and extension of the lows in both DTS/DD. I may try bypassing the outboard controller(NHT SubTwoi) altogether, running the LFE directly from the Processor to the Sub. I'll lose Phase control and the LFE gain, but....I have phase at 0 degrees and I can easily compensate the gain with the Processor itself. I will repost after experimenting. Thanks again guys.
