War of the Worlds DTS

FWIW, Paul said (on another forum) that he measured 123 dB at the listening position with the sub only.

Your 3500 cu. ft. room is exactly four times smaller than his, so your output using 4 Tempests *should* be just a bit shy of what his will do since you have a bit less than four times lesser Vd.

Cool, thanks smith.

I just wanted to know, I've heard many good things about Tempest drivers. Would they be appropriate in an IB installation? And for the same price, are there better drivers available in terms of sound quality and/or clean output?

Thanks.

Vaughan,
Sorry I'm late getting back to this thread. Just to clarify, it sounded close, but the subs did NOT bottom out...I simply blew a fuse in the amp! The amp is fused to prevent accidents (like listening to WOTW way too loud) and it worked as it was supposed to. No problem, no damage to anything, no nuttin!

My bad, not the IB. Go for it!
Paul

Hi Paul,

I'm glad ro hear that there was no damage to your system. Sorry if I jumped to conclusions.

My bad. ;D

I can't wait to audition this one.

When I set up my speakers everything is set at 70 db with white noise and the sub comes in at 75 to 80 I think. With a RS meter the max reading below 80 hz is 85 db using test tones.

When you guys talk about your setup being "hot", what does that mean? I have a lot of people complaining about things being to loud.

[ThomasW]

'Hot' just means having the output level raised.

Depending on the source I make adjustments in the sub level. If I'm watching OTA-HDTV, I turn the sub down becasue the stations add too much bass boost. For DVD I run +4dB 'hotter' than I do for music

Don't forget that the RS meter typically reads a couple (or more) dB low at and below 80Hz, so if you set up the sub for 70 dB indicated with the test tones you are already "hot". If you're showing 75-85 dB with test tones below 80 Hz of the same level that shows 70 dB in the speech range you're *way* "hot". It will sound unnatural, and most people of the female persuasion (who else matters?) won't like it at all. They mostly think theater levels are too loud anyway . . .

There's a correction table (which may or may not match your meter) at:
