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 also own SC-V's. I listen to a fair amount of organ and electronica which are the only instruments with fundamentals below 27Hz. I use a Sigtech and with a realtime analyzer measure my Sigtech corrected Dunlavy's flat to 22 Hz with very decent output at 16Hz due to room placement. (Try the Dutoit recording of the Pines of Rome with a 16HZ pedal on the final track).

I've tried several Subs and have found that they detract from the Dunlavy's for music reproduction. I only use mine when we set up the room for dance.

I wouldn't use a sub with your speakers. The bass the Dunlavy Vs produce is so deep, accurate and tuneful that it seems to me that you're more likely to hinder the overall presentation in both balance and soundstage.

Good luck, Dave

I found two things really made my rel sound good. First it was designed to go into the corner.

Second is the crossover setting. If your speaker cut out at 21hz then your Rel should be set at 20hz with the volume on the rel on the high side.

All crossovers have bleed through. The volume turned up on the Rel creates a little more bleed through and helps cover the small gap between 20 and 21 hz. If you put them both on 21 then they overlap and it gets boomy.

This is how Sumiko told me to set it up and it made a HUGE difference.

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.
