first of all, happy thanksgiving to all!! it has been a while since my last visit here. My theatre room leaves a lot to be desired acoustically...dont they all..... I have found the best placement for my RSW 15 but it is all the way across the room ( a combined living/dining space or great room if you will ) by the dining room table. This is not the best location acording to my wife, and the idea of any room treatment is out. If I move the sub anywhere else in the room it creates a node right where my listening position is. I lose all audible frequency tone but keep the impact----I can feel the inital strike of a concert bass drum but I cannot hear the ring. I realize that the acoustics of the room are determined by the size, construction, and design of the room but do different designs of subs "act" differently? Would I experience the same nodes with a sealed rear firing sub versus a ported front firing one? How about the new triangular klipsch subs. I have no experience with this so I am asking some of you experts out there!! thanks for the help!!

The history of the speakers (to my knowledge)--- Bought in japan at a military PX by one of my former platoon sergeants at a tent sale during the mid-late 90's. brought back to the good ol' USA and traveled from California to Lousiana and sold to a lucky Private because said Platoon Sergeant couldn't fit them inside his new base housing comfortably. I used them since then for a low budget/high performance (so I used to think!!) home theatre. They are in good shape and I have replaced on of the woofers in 2005 (15"!) due to the foam surround rotting. The new woofer cost almost $300!! The level controlls for the high/mids are a little scratchy but could be restored with a little TLC and some contact cleaner. These speakers would make a great starter system for 2-channel or mains for a home theatre. I have not set a price but would like to get back out of them at least what I paid for the new woofer. The only reason I am selling these beasts os to make room for my RF-7s!!!! original retail for the pair was $1,200.00 email bentrek@camtel.net for more info I also have matching center channel CC-2 in excellent shape that I will throw in for free (orig. $350.00) Frequency Response: 44Hz - 25kHz (+/-3dB) Crossover Frequency(ies): 500Hz, 5.5kHz Sensitivity: 102dB (1 watt/1 meter) Power Rating: 10 - 300 watts Nominal Impedance: 8 ohms Woofer: 15" (381mm) polypropylene coated Midrange Driver: TWO - 4.5" (114mm)polypropylene coated Tweeter: 1" (25mm) high-output polycell Center channel specs: Freq resp--90-20k Sensitivity--90 db 8 ohm peak output--110db power--10-100W two 5 1/4" mids and 1/2" polycarbonate tweeter crossed over at 3khz

THANKS TO EVERYONE FOR ALL HELP AND ADVICE!!! I haven't had any time at all to try even moving the sub an inch!!! I will be getting married in two weeks and things are getting pretty crazy around here!!! Not to mention I work 12hr shifts at CITGO. I will definately be investing in a meter some time in the near future. Does anybody have suggestions for a test cd/dvd that will aid in not only sub placement/performance but help in evaluating the entire setup? I don't know if other companies have this kind of customer support/camraderie but I am blown away by this forum and the advice and support given to each other here. KLIPSCH ROCKS.

i believe the recommendation from the klipsch manual was 3-4" clearance but I assume that it could react differently in different rooms. I will need a test CD/DVD and a SPL meter to really get serious about this...sigh...any good suggestions for a good meter that doesn't cost an arm and a leg?

concerning the rf-7's They are placed about 1.5' from the 8' wall (see above for room desc.) The left is located near a side wall with enough room between it an the corner for the sub and the right is also in a corner but it is only a partition that extends about 3' from the wall....I will try to come up with a visual aid

concerning the sub...currently it is placed right next to the left rf7/ in a corner with about 2in clearance to the side and about 3in. to the rear. The "sweet spot" problem began in another room measuring about 14'x13' with an 8' ceiling. I tried the sub in three different corners and found the best place to be in the left rear corner behind the listening position. I suspect that the difference was in the makeup of the wall (it was an outside wall which would include insulation and a brick backing versus hollow drywall everywhere else) The sweet spot in that room was located in two places on either side of the love seat which was the only furniture in the room. In those two spots the bass was unbeliveable. When I sat down in the loveseat, the bass lost volume and seemed to drop out frequencys---example--- when listening to classical/movie scores and a hard hit on a concert bass drum occured, I could only feel the initial hit of the drum but not hear the frequency generated by the movement of the head while sitting in the loveseat. If I moved to the sweet spot and replayed the track, it was a totaly different experience ( a wonderful one!! ) these two listening positions were only about 2' apart. Also worth mentioning is steping outside the room into the entryway proved to be yet another sweet spot where the bass relocated my brain cells! All I ask is that I can have the same experience while sitting comfortably in front of my 56" DLP Samsung!!!!!!! Since then I have relocated the system to another room in hopes of more tuning possibilities. this room is larger 23'x19' with a sloping 8' to 17' ceiling and is open to a med.size kitchen. after initial setup, the bass is pleasing and actually better in the listening position than in the smaller room but while sitting here in a totaly different room the bass sounds better formed ( more distinct ) than in the room with the system.

I have been looking through some of the posts and have seen some information regarding upgraded crossovers for the rf-7's. where can I find out more information i.e. price,benefits, where to buy? I am currently "breaking in" the beasts by playing various types of music/movies but am finding the sound to be a little bright still, I am using the yamaha rx-v2500 as my amp/processor and not finding a lot of adjustibility as far as changing the actual equalization. Also having trouble with correct placement of rsw-15. I seem to have "sweet spots" where the bass is mind-numbing but they are located nowhere near the listening position (I am in a totaly different room and the bass drum from the First Knight score is moving my shirt; it is mediocre at best in the room where the sub is at!) thanks to all who can help a budding audiophile/theatre geek
