No bass from Sony str hd520 receiver

by scottwski / January 26, 2013 12:05 AM PST

I just bought Sony str hd520 receiver and have it hooked to to large front speakers, a center speaker, and a sub woofer, but very little bass even with bass turned all the way up in settings menu. I feel like there is a setting I am missing. Help?

Powered or Passive?
by sunwatcher / January 26, 2013 1:17 PM PST

Do you have a powered or passive subwoofer? Make/model?

If it's a powered sub, then have you set the sub's crossover to maximum?

If it's a passive sub and you have it attached to a speaker output on the receiver (not the sub out), then you will not hear the low frequencies since the LFE channel is only sent to the subwoofer audio out.

LFE and Sub

I should correct myself when I said the LFE is only sent to the sub out, which is not the case. But again, the crossover should be set to "max" on the sub itself. The receiver speaker pattern should be set to 3/0.1.

Yes, it is a powered subwoofer and I have it connected to the subwoofer connector on back of receiver but am not sure of make and model or what the crossover is set at because I am currently on vacation. I do have the speaker pattern set to 3.0.1 I know. I will get back on the make/ model as soon as I return home. ( I read somewhere that front speakers should be set to small even though these are big speakers? Heard of that?)

If speaker size is set to "small", then low frequencies for that speaker will be sent to the subwoofer and not the selected speaker. I've heard the same thing about the setting... you don't want two different outputs producing low frequencies, so keep them set to small. Also be sure to double check the phasing on all speakers.

Sony str hd520 no bass & question about surd. snd. rear sp

So I finally got back from vacation and changed front speaker setting to small and that finally fixed the problem. I also adjusted the output of the subwoofer in the speaker level settings and now I have plenty of bass.
I would like an opinion from someone who is more surround sound savvy than me. I have two large front speakers, a center speaker, subwoofer and two medium sized speakers I have set up as side speakers. In order to install rear surround speakers, I am going to have to have someone come in and put them in the ceiling flush mounted. What I have now sounds very good; will putting in the rear surround speakers make THAT much difference? The installation will be very expensive I'm sure, and was just wondering if it would be cost effective.
