THX and Bass Mgt

I had this in the opinion area, but it really needs to be here:
I have an Onkyo 898 THX receiver to go with my new RM7600 speakers which I haven't had a chance to set up yet (receiver arrived yesterday).
I want to take full advantage of THX, DTS, and Dolby Digital movies but I'm not sure which speaker/subwoofer wiring arrangement works best with all three without compromising the movie sound qualityof any of these formats
One issue of the Speaker Specialist wrote about Bass Mgt ('The THX Exception') and it mentions that when you switch to THX mode that bass mgt filters are activated and the front L/R and centers are high pass filtered at 80 Hz (bass removed below 80Hz) and that the subwoofer output jack is turned on to high pass filter at 80Hz as well - which I guess means that I should hook up my PSW650 to the sub-out jack - I thought that the best set up was to not to hookup the woofer to the sub-out because it has a fixed cut off - I'd rather use the PSW650 to adjust the bass roll-off and not be constrained by the sub-out's inflexibility yet at the same time take full advantage of THX, but not at the expense of DTS, and Dolby Digital.
- can anyone recommend the speaker/woofer wiring that lets me do all 3 formats at their best? Your help would be greatly appreciated as I need to know what to do before I get started on setting up this system :-)
Thanks,
Angel

Hey Paul,
Thanks for the feed back, I'll try it!
Thanks,

Ps - Wow!, NICE LSi speakers - hate to bug you, I know this is subjective, but what LSi speaker model would you guess would go well as a front L/R with my new 110watt Onkyo 898 rcvr (it has the 192Khz DACs and 7 channels) and RM7600 speaker system? The five RM7600 surrounds would be used to fill out the remaining 5 channels -
Paul, my room is 11x18 - quite small. theLSi 7 is more in keeping w/my budget (then again, with allthe home theater goodies out there, a budget can become an afterthought) and within the capabilities of the 898 and the room that I have. they sure would look nice w/7600's. Anyway, I hope the line really takes off!

Thanks Paul, by the way, who is your boss and what did he major in? Anyway, I'm a big Wolfpack fan (micah is a UNC fan - NCSU and UNC fans mixe like oil and water) . . I go to all the football and basketball games and graduated from there in '89 (industrial engineering). So, where did you grad from?
So in your advice above, the Onkyo's 110 watts per channel @ 8 ohms (.08 THD) should be sufficient to cleanly drive the 2 LSi7's
for music and also serve as front L/R for movies with my RM7600's and 650 right?
With that in mind, do you think that in movie mode the LSi7's would blend in well with my RM7600's and 650 sub, or is this a dubious proposition?
Sorry for all the questions -
Hey Paul, you get brownie points just for being ABC - ha, haaa! But I hear Micha is a UNC fan, so you haven't completely eradicated the problem (seriously, Micha is alright, he can stay :-) I went to the Duke/State game, tailgated, and had a blast. Terps are hot, Fridgeon has turned the team around overnight! I hope State can beat them in Raleigh on the 17th. The only thing about the Terps first year succes under Fridgeon is that the fans next year are going to expect the same performance - that's not easy for a new coach repeat.
No rush on the LSi7 issue, I'm in the process of setting up my 7600, sub, and new rcvr - I won't finish 'till this weekend perhaps. I have to travel to Detroit Wed thru Friday, Carolina Hurricanes/Penguins hockey game Tuesday night, and take my girlfriend to meet my parents tonight. I think I need to take a few days off from work and lock mydelf inside the house just to finish my set up and learn this system!! To be honest, half the fun is putting this together and later tweaking it. I have a playstation2 game console and am getting the Micorsoft X-box console next week - video games for the x-box do support 5.1, so it's going to awesome playing video games on this system. Talk about getting full use of a system - music, movies, and 5.1 video games!!! This may be a useful marketing point - feel free to use it and tell 'em I sent you
I think that if the LSi7 will not blend in with my 7600's & Sub, then the next option for me might be the RTi55 - do you think? -
This tarheel loves his 55s.
So there.

I had the THX Ultra certified option on my receiver, but the first time I used it, I didn't like it at all (you have to turn the volume control way pass the 12 o'clock position to hear anything), so I never use it again. I always use the standard DD and DTS option and follow the set up procedures.
