Axiom Home Page Forums General Discussion Advice from Axiom Owners EP500 - No / Barely any LFEs

History:

Got my Axiom in/ons & Qss, installed, set up ran Audyssey using my JBL 10" Sub. Everything sounds incredible. So ordered a W100, and EP500, installed ran Audyssey. The Fronts Centers amd Surrounds sound incredible, not much from the EP500. Set it up as instructed Vol @ 10 o'clock, Phase 0, Crossover @ 120, Sub sonic off.

Audyssey (with EP500) set fronts to Full, and the rest to THX (80 crossover, forgot Sub setting)Not great sounding. Audyssey set the Sub at +12db also.

Reset the crossovers to Fronts 90, Center 80, Surrounds 100, Sub to 120. I set the sub db to 8.5

Watched 2012 last night nada, totally un-impressed. Wasn't watching it real loud, but didn't have to with the JBL 10".

What other setting could it be? I was expecting liver damage from the EP500!

Thanks

Time to back things out of the equation. The first place to start is backing EVERYTHING out. If you've got an iPod or MP3 player, or portable CD player, hook that directly to the input on the sub. Make sure you have the sub turned down. Then press play, turn up the volume on the sub until you can hear something. I think the new EP500 amps need to be at about halfway (could be wrong, be careful). If you never hear anything or if it's very, very soft, double check the RCA->1/4" adapter plug. At this point, there could be a problem with the sub amp.

If it works fine with the MP3 player, try setting things up in the receiver manually, without Audyssey.

Thanks, I'm getting something out of the sub. I went up and listened & heard the sub, it's outputting, I could hear bass during the movie from my seat.... but and the LFE's, tiny body tingle. but I would think the 2012 earthquake scenes, just might make you know something was going on. I'll try some music or a movie with my droid

Thanks Again

Jeff, what caught my attention was that the sub had been set to +12 by the auto-calibration. This indicates that there wasn't enough room to set it louder with that setting(10:00)on the sub volume control. Set it substantially higher so as to end up with a receiver sub trim closer to 0.

Hi wordgasm,

I would forget about the auto setup for now. Try this...

1)Go into your receiver settings and set the subwoofer pre-out to +2.
2)Set speakers to small with 80 hz crossover. Subwoofer set to "yes" or "on"
3) Play some music
4) Adjust the control on the subwoofer starting at our initial point at 10 o`clock and adjust upward to the point where you get satisfactory bass.
5) If you get the bass you are looking for, we then take another step on how to fine tune your subwoofer.

Buy a ratshack spl meter and level match properly. Also, take the time to do the sub crawl to make sure its not room related.

I agree with JohnK. Having owned 2 EP500s, I would turn the gain to 2 o'clock and recalibrate.

Bingo. Turn the sub volume up about 1/4 of the dial and try Audyssey again.

Thanks All, all responses make sense .... I'll start with the easy one.... recalibrate at a higher volume.

Any updates on your issue here wordgasm?
