Help configuring my subwoofer

Kuergan

Hi,

I've been trying for months to achieve the best configuration on my home theather and so far I believe I were not able to configure the subwoofer correctly.

Regarding the room, this is a little trick. It is 13 feets per 26 feets however the tv environment is just half of it.

What I have
- Receiver: Onkyo HT-RC270
- Front: RTi A1 bi-AMP
- Central: CSi A4
- Surround: RC80i (ceilling)
- Sub: PSW111 LFE located on the corner of the room. (10 inches subs won't fit on the spot)

My Current settings are:
impedance: 6 - Onkyo has only 6 (for 6 to 16) and 4

Crossover settings:
Front - 50Hz
Center - 60Hz
Surround - 40Hz
LPF to LFE - 80Hz

Main concern, I'm not looking for a BOOOOMMMM, and walls shaking, but I fell more bass from surround then sub.

Should I increase LFE to 100 or 120?

Any help is welcome. Thanks in Advance

I think you got things a lil backwards. I would make it simple and set everything to 80HZ. Changing your sub to 100-120 actually is decreasing the bass frequency from your sub not the other way around. What is your subs trim level over the fronts? Also with that?s sub and the dimensions of your room the advice from me would be you need a much bigger& better sub. That?s a lot of area to pressurize. Just my thoughts others will chime in.

Your crossover settings are off. The RTiA1 has a lower -3db cutoff at 60Hz, the CSiA4 at 65Hz, and the surrounds at 50Hz. With your current crossover settings there is a lot of bass that is simply not being handled by any speaker--it's just being thrown away, essentially. And with the in-ceiling surrounds having the lowest range, it will of course sound like they are producing the most bass.

Try this for your crossover settings and see if things sound better:

Front - 70Hz
Center - 80Hz
Surround - 60Hz
LPF to LFE - 120Hz (highest setting possible)

I was checking some other models to replace it, but the dimensions limit my choices; 8 and just a few models with 10 inches. I friend told me about Mirage Omni S8. Just looking at the specs I could say it is looks better, but not sure it would be a "solution".

I'll configure it tonight and make some tests... thanks for the help.
I tried once a 80 80 80 80 (THX settings according to Onkyo Manual), it sounded good for movies, but crap for the rest

Could you go DIY and configure the box size to your space requirement? An 8 inch sub just isnt that much in the volume of space you described. What about a cylinder style sub like SVS offers its got a small foot print but uses a vertical style cylinder to get the proper airspace?
