I have an ONKYO tx-sr605 receiver and Boston Acoustics t930 speakers (20 years old) as the base for my home theater. I have to turn the volume way up to get decent sound. I think that the speakers are power hogs but I am not sure. Any suggestions?

No reason that the Onkyo should not be able to power those Bostons.   Have you considered that the Speakers may need to be re-foamed.  Have you connected other speakers to the Onkyo and how do they perform.

A quick search on Google shows that those speakers have a sensitivity rating of 91dB and they are 8 ohm. There's no reason that the 605 should not be able to make them play very loud. They are definitely not power hogs. :D What do you mean by 'way up'? And have you run Audyssey?

I have had to turn it up to at least 65 to get a reasonable amount of sound. I ran Audyssey last night and i get the same result.

I refoamed them last year with parts from BA. Should I consider refoaming again?

You may just be too accustomed to receivers which reach max level about 1/4 of the way up.  They generally don't work that way anymore.  If you get decent volume at 65, but it goes up to 100, you are fine.

I'm pretty sure that reference on the 605 is around 72 on the volume (the 605's volume display is not relative or absolute - it's some sort of scale). So if 65 sounds good, then you have nothing to be concerned about.

Thanks for all of your help. I have adjusted the individual speaker levels manually and it seems to be ok.

I bought a Yamaha RV-371 receiver a few months ago and I want to look at new speakers for 5.1 in an apartment. Any suggestions?

Hello Gregory,


Welcome back!


You posted this same question in another (new) thread, and already got a first reply there.

I suggest we continue that conversation there, to avoid occasional bewilderment, and I'll close this one therefore.


Thanks for understanding.



Cees
