post #661 of 865
My room is 2150 cubic feet. The cabinet is bigger slightly on the 450, the cone material is different, and the mounting plate for the mids and tweet are aluminum on the 450 and some other material on the 370,s What's important is they sound very similar which makes for a cohesive soundfield. I put in a couple of picture so you could see what I,m talking about

Also, these speakers are Ultra. Was there a significant change in the THX spec to Ultra2 / Select2 that I should trade these out for a set that has the newer spec (4400)? My surround backs are both dipole and the newer spec has directs next to each other. Should I get 2 bookshelf speakers, like the AT-2, to replace the rear dipoles? Thanks for any guidance.

I have a original Ultra 370 setup with a small SVS sub for our little home theater room which measures about 12' by 12.5' with a small entrance alcove. I bought them new and have thought about upgrading several times over the years. However, I find the sound so great with clarity and dynamics with movies that I don't upgrade to something else. In the past I have found some other brands that I've had in the room too bright for my tastes with the way that some movies are mixed.

I disagree, the 450's are a big step up in my eyes. Someday!

System 350 mains use 5.75" woofers and 3" mids; the rears use 4" woofers

System 450 mains use 6.5" woofers and 3.5" mids; the rears use 5.25" woofers

I have a review of the original system 350 as well as AT's spec sheet comparing the 370 and 450 which give the driver size and driver materials:

The 350 uses the size drivers that you state in your post, whereas the 370 uses 6.5" woofers and 3.5" mids in the L/C/R and 5.25" woofers in the surrounds like that of the 450. The 450 is stated to use Injected Molded Graphite materials in the woofers and mids whereas the 370 uses Coated Composite Molded Graphite. The 450 uses an aluminum mid-tweeter mount but the 370 uses a molded mid-tweeter mount.

I cannot comment on my impressions of the sonic differences among these speaker systems as I never heard either the 450 or the 350. I bought my 370 THX Ultra back in 1999 and have used it in my small HT system since that time. I have a separate dedicated 2 channel system that I use for listening to music so my impressions of the sound of the 370s is primarily with movies and TV.

I stand corrected! I thought a system 350 and 370 are the same except 350 had 5 vs the 370 having 7 speakers. I learned something today!
post #666 of 865
At one time, I thought the only difference between the 450s and 370 was that the 450s had a nicer piano black finish. Bought both. Turns out that I was wrong (what else is new lol). The 450s really do sound better than the 370s. More detailed and broader dynamic range....regardless what the specs say.

As I recall, the AT dealer where I bought my 370s told me that the 450s are more dynamic, can play louder, and sound different than the 370s. I no longer have the Home Theater review of the 450, but from what I remember, the comparison in sound with the 370 was similar to what you state here. That being said, the 370s sound wonderful in our little HT room with the SVS sub.

As trivia for anyone that might be interested, the Suggested Retail Price (January 1, 1999) of the entire System 450THX Ultra was $5496.00 while the System 370 THX Ultra was $4296.00

Thanks for everyone's help with getting over my most recent bout of upgraditis! I will stick with the 370s. (Although, I stand corrected in that there is more to the 450s in terms of parts quality that likely provides sonic improvements.) After adding the AT sub to the back of the room and re-running Audyssey and listening again to some tough scenes, I'm very satisfied that I couldn't squeeze out much more performance from my system.

Just to satisfy my curiosity, I picked up a set of B&W CM9s and a CM2 center and A/B'd the setup and decided there just wasn't enough difference to justify the significant expense. Caveat: in my room, under my circumstances. YMMV!
post #669 of 865
Hey folks,

For the people still using the 370s or 450s , what do you have them crossed at? Audyssey keeps setting mine at 110 or 120 . Bit confused! The center is set to 80 though
post #670 of 865
When I was still running my 450's it would try to set them at 70 or 80 for the fronts and 120 for the rears. I'd leave the fronts at 80. I figured that is what they're designed for. But maybe the crossovers where allowing a little lower frequency hence the 70 recommendation

Gaahh gotta try to run it again then!

Having a tough time deciding about In Walls.
I am torn between going with the IWTS-30 or the 6200e's for the front. (Can't really audition locally)
If I go in-walls I was going to do the in wall sub too.
I am def using the IWTS-30 SR for the back. I am studding out now so I have easy install options.
I just have a hunch that the 6200e and 642e will sound better?
It is a pretty big basement room.
**Also I was going to go with IWTS-14 for my bar area TV
Thoughts? Thanks a lot!!!
** I've had a AT 271 5.1 THX system in a smaller room for years and love it.

Does atlantic provide sensitivity numbers for anaechoic rooms or in room?

My 370 system with SVS sub was crossed over at 100 when calibrated by Jeff Meier (UMR) of Accucal http://www.accucalhd.com/ even though the Atlantic specs in the owner''s manual are stated to be 80Hz-20KHz. Jeff stated that this higher crossover was necessary to yield a more even frequency in the crossover; at least in my room with my SVS sub.

Here is a link to the audio calibration services that he provides:

(long time lurker, first time poster)

I own a set of the AT System 370 speakers. (Had them about eight years now. Love 'em.) I'm debating making the jump to Audyssey DSX. Any thoughts on what speakers would match for wides/heights? I'm pretty sure I can't swing installing four more 371s. Would any bookshelfs from the current lineup work? or should I try to look back at AT products from eight years ago to match?
post #676 of 865
Try to find a pair of LR Atlantic Technology 4.5 's they are small but use the same tweeter used in the 370 and 450's They measure 6.5"x4.5"x10.5" The come in Gloss black. Ive included a photo of a 450 so you can see the center section of it is what a 4.5 is

post #677 of 865
Not saying they are bad but are you sure you want wides? Not really a fan of DSX
post #678 of 865
Thanks Dennis. I had a feeling the older models would be better matched. I'll start looking for them.

pokekevin - Mostly I'm just looking for something new to mess around with. I might love it, I might hate it, but it'll be fun finding out.

Just recently picked up the 2200 5.0 series and I have a stupid question.

The speakers have spring loaded terminals on the back. How do I connect banana plugs to these speakers? With the screw-down terminals its easy enough, but I'm completely blanking on these.
post #681 of 865
Spring terminals can not accept banana plugs.

Here is a pic of my in-wall setup rough in. (only 12'-0" wide) The back boxes are for the LCR-30's. Putting the center in the horizontal took a little more effort but it was worth it. Don't for get about the offset of those boxes to get everything centered up!! I could've saved a pc. or two by making the header wider but oh well. Gotta add some cripple studs wire it up and get some drywall hung!
There are some "unique" things going on in the pic. Any questions (explaining) don't hesitate to PM me or post up. That wire above is from the prev. owner...(coming out soon)

Seems like there won't be any soundproofing in-wall installation
post #684 of 865
Boxes are factory filled. But a little more is coming.......

Looks great. Can't wait to see the finished product and read your impressions of how they sound

Why is your 371 cabinet color/material look so different from what I have? Mine is like in black with wood grains. Did they come in different colors?
post #687 of 865
The 371's were available in the black ash, and natural finishes. When I went from a 5.1 to a 7.1 system, this was the only color available new that were available at a closeout price

Thanks for the info. I think they look beautiful in black. I love the glossy look on the 450s though. Any chance of you selling the 450 LR channels?

Damn makes me wanna spray paint the silver part on my 450s lol. Never really liked the gloss finish cause it made it look like I had 2 luxors in my room when I watched movies lol
post #690 of 865
Wow! Are the AT 8200's and the Triad Gold LCR's the same speakers???
