Below 20 HZ Notes/Instruments

Thanks to you all. Rcprince, I did try the pomp and pipes, actually 2nd and 4 th cut which has both organ and kick drums. I also tried Asante from Maplesahde which contains lots of drums that ranges from 20 hz and up, with ambient info lower than 20 Hz,( by feel). Yes, Sumiko did suggest the Sneakers soundtrack, and I will see what others have to suggest. But so far my conclusion ( after spending about 3 hrs of listening and tweaking and right now completely tone-deaf)is that although the REL adds 'musical' Content at the basic reference 80 db level now up to 15 Hz, with - 4db at 13 Hz ( all measured withRadioshack meter with requisite interpolated corrections), it ADDS 3-4 db from 20 to 30 Hz, (even at lowest crossover point of 22 Hz and Volume set at midpoint), upsetting overall balance. The subwoofer location w.r.to left and right speaker further deteriorates the perfact imaging (both time and phase coheraent) the Dunlavy V's are capable of. Overall result is obscured soundstage ( hard to believe but I trust my hearing) So I may use it for HT set-up or the Stereo surround casual and dance music, with cross-over now set at 49 Uz for that night-clib added, but musically clean PUNCH. What do you guys think? Am I giving up too early?

I think the answer would be to have two Stereo RELs Placed symetrically with the main speakers and then adjust the volume such that it blends with the Dunlavy's. Setting will be still at the lowest 22 Hz cross-over cut-off. So now the imaging is right from L-R but depth could be still off. I am considering to have the matching Tower subwoofers that Dunlavy makes. Of course the option is much more expensive both $ and space wise, and a question is still there if it is gonna work for music.( like the main speakers are capable of on their own. Bass originates precisely at certain region in sound stage full bodied and deep with lot of air) All for last 5-10 Hz!! If They are only for movies then I would not be interested. I must be crazy even to consider it. But I got extra amplifier and matching cables laying around... The quest continues.

I was persuing the Dunlavy Tower subwoofers option futhermore. ( They have info on their web site- spec and description summary and some owner systems). The description mostly talk about the bass notes that can be heard from the movies. The built in cross-over 20-100 Hz tuned similar to the V's and that the DTS's should be placed right next to the V's. No mention of music! I am skeptical about musical merit of this arrangement. Of course I will have to call them tommorow to find out more. If this works, man that would be one heck of a stereo!!!

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.
