Below 20 HZ Notes/Instruments

I agree that the rel has to be able to be set lower then the mains. If not its just going to get boomy. Maybe a better Rel? I have Stentors and I think they go down to 17.

Two Rels will break the bank. I had the first one for three years before I bought the second and the only reason I did, when I did, is because the Stentor 3's were coming out and I wanted a 2 to match my current one sonically.

Try the corner and let us know what you think. You have nothing to loose and you may be as suprised as I was.

I'll dig out another list of low bass CD's that I only have on paper. As for acoustic instruments it is pretty much a few pipe organs to 16HZ. The extended double bass and contrabassoon bottom at 27Hz. However the big Bosendorfer grand piano has a unique musical "rumble" below 32Hz due to resonating strings tuned below the end of the keyboard. A few years ago I had the chance to use an RTA on one and there was a fair amount of sound in the 16-32 HZ range but not enough to require any kind of sub woofer on top of the Dunlavy SC-V's

Lots of electronica these days has sub sonic electronic drums

Here is the list. I got it from Dr. Hsu of Hsu Subwoofers.

Gentleman, to each his own. But, there are some fundamental reasons why subs are best placed in a corner. This doesn't mean jam it anywhere, of course, each room is unique. I just wish everyone could hear a good musical sub. Charlie
