Below 20 HZ Notes/Instruments

Thanks P1s1. I will be sure to check out the top 30 bass CDs. Danvect, that is what I thought but in my case I could locate the 'pressure source' even with lowest possible cut-off of 22 Hz on the REL stormIII and lowest possible useful volume , perticularly with nearfield listening ( relatively speaking, my V's are 9.5 ft apart and sweet spot is at ~8.5 ft distance.)I tried the subwoofer at different loations; near left, near right, middle, back(never a corner since that is the last thing I would want) and each time disruption to main speakers occurs (to my ears,the wife and daughters can't tell the difference!). One thing is for sure , the REL does put out big clean punch during the casual listening and movies ( Watched the fast and furious and Pearl Harbor over the weekend). Seandtaylor is correct that for the V's REL or any subwoofer unless specifically designed would be just counter productive for music.

P1S1, What do you know, I GOT some of the CDs from the top 30 bass discs. 1812 overture, food for woofers #3(i got all 5 volumes), Illegal bass, techmaster P.E.B, Bass Mechanik (this is where I got the freq tone down to 10 Hz, actually this has tones for 10-11-12...100 Hz!)Bass erotica, Bass syndicate, bass society,bass hit, bass alliance,and many more bass cds. These were from my old car bass freak days ( I still am but towards flat and clean bass, My car stereo is so good I refuse to replace my old 88 Honda PRELUDE si) Thanks again. What are the acoustic instruments that can go that low? Not too many i think.

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.
