I have an SVS PB-U13 with Klipsch (Rf82's,Rc62,Rs52's and Rb61's) speakers.

My speakers are calibrated to -75dbs, but I bump my sub up till my Spl Meter reads-76/78 dbs. At 75dbs my sub has no slam for most movies, mind you I watch at -15 from 0 on my Onkyo.


What I am out to ask is DO MOST OF YOU run your subs 3-5 dbs HOT?

where do you set your sub at

[Todd Lee]

Yes, I do as well. (PB12-NSD)

I run flat and have plenty of bass. Something isn't right if you have to run hot all the time.

It's not about "have to". It's about want to.


Also, unless you have Dynamic Volume/EQ, it is important to remember that "flat" was set at reference when you calibrated your system and VERY few people actually listen to movies at that level (who want to keep their hearing). If, for example, you listen 10+ db less than reference, then bass (while it may still "measure" flat) will not sound flat. That is a function of the way we hear. So many will crank up the bass. I have mine up a few db's ... at least until I get a pre-pro that support dynamic eq/volume.

Strangely if I use Audyssey DynamicEQ or THX Loudness Plus with my sub calibrated to 75dbs, the tech will bump it up to 76/78 dbs at fifteen below zero.

Maybe you answered your own question. DynamicEQ is suppose to correct for bass levels at lower listening. I wouldn't now cause I never bought an avr with it because I don't listen much below reference ha.


Also when your meter is at 76-78 you are actually 3-6dB hot

I have the Integra DHC 9.9 with Dynamic Volume/EQ so that does explain it. i never have upped my sub bass for any movie with Audyssey Multi EQ. I guess that is why I love it. When I had the Pio 94 with MCACC, I was always turning up the bass and sometimes up to 9+ db from 75 db with the mains. Audyssey has made a believer out of me. That is one reason I am selling off the SMS-1 and Anti Mode as I don't really need them.

What is it about Audyssey that doesn't encourage you not to turn up your bass? I am assuming with the SMS-1 and Anti Mode, you had a flat response with your Pio 94. Is there something that the Integra does better for you?

 

[darkhorror]

Have you checked the subs freq response? That could be why you aren't getting the sound you are looking for. If you check it and see that it's flat you may just like it running hot.

Total audio is BETTER and more detailed along with the bass. MCACC only does 3 positions and the AUDYSSEY does 8 and 32 with a installer doing it.

audyssey eqs 'flat' at reference level (0db). dynamic eq boosts the low end at lower volumes, to make up for the fact that human hearing is not flat across the spectrum at all volume levels.


so, if you use dynamic eq and do not listen at reference levels, the machine turns up the bass so you don't have to...

http://www.audyssey.com/technology/dynamiceq.html


looks like at -20db levels the boost is ~3-4db at 60-500hz, maybe twice that under 60hz.

FWIW, in my room with my sub (which is not necessarily a super sub) and with Dynamic EQ engaged, what works best for me is to set the sub about 2 dB lower than the automatic setup (through Audyssey) comes up with. I think I vaguely recall liking the sub a bit hot (maybe 3 dB) before I got a receiver with Dynamic EQ, however. But I tend to listen in the -10 to -20 dB range (versus reference) most of the time.

That is pretty cool...didn't know Audyssey had something like that.

not all implementations do.
