Axiom Home Page Forums General Discussion Home Theater sub....liminal

Subliminal, sounded good anyway. In regards to Audessey/sub setup, with the onkyo, and the energy esw-8. The autocal seems to be ok. I can here the sub, but I really want to feel the sub. It's been less than 30 days, should I send back to Audio Advisor and try something bigger. Room is about 11'x14', and I am about 12' from sub. I can slightly feel effects, but I would almost like my hair to be blowing when there was explosions or the like on most movies. I think the sub does fine for music, but I tend to watch more movies. Any suggestions from the Audio Advisor line up.

Or for reasonable price from Axiom. Remember I have 6 kids, a wife, and three dogs. So I am slightly budgeted.

Looking at the specs for the Energy, it just can't play low enough to give you the effects that you are going to FEEL more than hear. Now granted, specs aren't everything, but if those that are reported (33-150 Hz, +/- 3dB) are accurate, the speaker just can't do it (though it does a lot for the price, no question!).

For something that'll really rumble while playing movies, I'd look for a sub that has a relatively flat frequency response down to 25 Hz.

The other thing to do just to be certain before you return your sub is to do the subwoofer crawl to be sure you have the sub in the best location in the room, which is ultra-important no matter which subwoofer you're using.

In my experience, an 8" sub only enhances the bass, it will not allow you to feel the effects, even a 10" sub is barely felt, IMO. You need a 12" driver to really move the air and be felt. I would send that little 8" packing and save up till you can afford the EP350 or PB12-NSD or similar. Looking for a used 12" sub as well will save you some money.

If what I am understanding from all advice and info. so far, is that I not only need a bigger driver, but also one with an amp that is capable of getting way down there.

In general terms, I understood that smaller drivers (8-10") are usually better for music because they react quicker, where 12"+ drivers are better for effects because they go lower. Anyone?

Not really. The quality of the individual driver determines how good it is a reproducing the sound information sent to it regardless of driver size. That is determined by linearity, damping blah blah blah...

Reproducing low notes is about displacement. Displacement is determined by the area of the driver and the length of throw. An 8" driver just dosn't have the displacement to reproduce really low notes.

There are some really good long throw drivers out there now that can reproduce sound accurately and have the displacement to reach absurdly low.

Tks Fred, but let's say both drivers were of equal quality, would there be any difference in the speed...I'm asking mainly because I've heard some people complain about their subs being slow (usually referring to the ones with large drivers in the 14-15" range, when they listen to music.(not referring to any spec. brand of sub)

People like to think so, but no, there is no difference in speed.

Size is only one factor in the performance of a driver.

Are you trying to tell me size doesn't matter, Fred ?
