Very few full range speakers will reproduce bass down to 20Hz. A lot of subs won't do 20Hz either. If you have output at 25Hz then you are doing very well.
Stereophile Test CD questions
Hi all,
I just got the Stereophile test cd's, and i'm trying to figure out how to use them. I have some very basic questions, so please bear with me. First off, how does one use pink noise? Secondly, I was pleased to see that the imaging seemed to be very good, by all their tests. Thirdly, as I went through the test tone warbles, wuth progressively lower frequencies, the volume seemed to diminish. I don't have an SPL meter, so this is according to my ears. 25 Hz. was clearly audible, but 20Hz. was barely there. Does this imply that I need a sub to fill out the lower frequencies? My room has no treatments, and the speakers are close to the wall, thanks to WAF. I plan to get a room in 6 months or so, where the speakers can be in th center, if that's where they'll sound the best.
Thanks,
David
