where do you cross over your ht setup

I agree that the power is in the hands of the sub.Most manufactured subs are not able to reproduce the bass of six channels.Not that they all are producing bass all the time because they are not.I watched the whole movie saving private ryan and the movie is in the sub.Build it big with out board amps and custom drivers and you too will feel what they felt in the post production studio.THX standards work.They work because of the practical use of subs handling the bass.Case closed

I´ve had the next door neighbour knocking on my door because there was a war going on his living room, I was watching Saving Private Ryan... ;)

Any way, what I really love to listen to properly is music, and I hear mainly the great sound tracks on movie and concert DVDs, the explosions and such are also there, very realistic too, I never fail to be fooled by rain and thunder on movies, always look out the window...

Music is my priority, movies are yours, we are both happy, cheers... :)

Enjoy the hollydays, and have a great 2004...

I must admit that a LARGE PART OF MY BIAS stems from my "long running" complaint regarding the shor-comings of passive systems in closely proximating "dynamic transparency" on the whole!
I still remember the first "real" high-end system I heard many years ago. The guy who's home system it was my pleasure to have heard, had a completely active system, that just blew me away!!!!...I din't hear anything even remotely close to that system, dynamically at least, until many many years later. His system was so dynamic IT HURT!!! There was soooooooo much power and dynamic ability there, that it left everything else I heard rather flat sounding and "gut-less" by comparison over the years.
Granted, that system was also very refined and "high-end" sounding as well...not just strong and dynamic!
That said, ESPECIALLY IN REGARDS TO HOME THEATER, I have very little impatience with whimpy sounding passive speaker sysetms that can't DELIVER THE GOODS when it comes to dynamic transparancy and general power deliver/dynamics!..which I think a good HT system should do.
I think more high end speaker makers should be building, at the very least, active woofers(for the demanding bass) into their speakers!
I have talked with many high end designers, and I find that the arguments they usually offer are "cost factor", "flexibility", "tradition", "practicality"(heat build up, space issues, etc),"public acceptance"! To me, I think the only "move-up" that can be made in transducers is to do more active speaker/woofer designs!
It's this reason, not to mention that that's what the "home theater experts" in the field have found, that I think the only way to really handle bass magangement in a passive sysetem, is to enlist the help of a crossover to a powered woofer of some sort!..it's like effectively bi-amping your system, and adding and active woofer to your bass chores...it's closer to what you need for dynamic accuracy.
If people don't want to do this, no problem. But don't think you're going to blow anyone away with your action adventure demo's at home!...that's all I'm saying. Because a lot of what's "exciting" and "involving" from a movie soundtrack, is the "dynamic ability", and authority a good movie has to offer...and a sound system needs to portray that more than anything!...that and dialog inteligibilty and lack of coloration.

Here we go again!.. I've been pondering much of what has been said above on this subject and decided to do some more checking on the matter. Here's an excerpt of an email I sent my friend regarding this dilemma and his reply. Said friend works very closely with the engineer who helped create the spec for THX Ultra2 (among other projects) in the Bay Area. Names have been changed to protect the innocent. To wit:

Dear Mr. X,
I have a quick tech question for you regarding THX
equipped processors/receivers. There's been a lively
thread on Audiogon.com in the "Home Theater"
discussion forum regarding where to properly set the
crossover for bass management for movies and home
theater. There's lots of debate regarding why it's
better to set your crossover to 80hz and set your
speakers to "small" (even if you run "large" front
speakers) to maximize dynamic range. Others say it's
better to set the crossover lower depending on where
the main speakers rolloff.

Correct me if I'm wrong, but isn't it true that
regardless what type of speakers you tell your Dolby
Digital processor you have (large or small) and where
you set the crossover point for bass during initial
setup, doesn't THX override those settings and default
back to an 80hz crossover, set all speakers to
"small", and route (or "sum") all LFE to the active
sub when THX processing is engaged? It seems to me
that's the only way THX could reasonably ensure proper bass
management and to coax the maximum dynamic range from
a 100 or 120-watt THX-equipped receiver which most likely will be used in a
variety of potential systems with different
brands/specs of speakers, room size, etc.
I'd love to hear your thoughts on this!

Mr. X's reply:

"Regarding your question, funny thing, (name omitted) called last week
with
the same question. You are correct, the crossover point is 80hz, no
matter
what size speaker is being used. As for your explanation, you nailed
it on
the head." (End)

I hope this helps to clear the air at least a little bit especially for those running receivers and/or processors equipped with THX processing. If max dynamic range is your goal for movies and HT, THX knows a thing or two about helping you get there!

Cheers!
