Just looking to see if anyone here has used these before and if they have how they like em? I made the mistake of installing flush ceiling speakers for Atmos and now the wife would really like it if I flushed the surounds. LOL

Bi-Amping is not going to gain you anything, I would run them with the binding posts connected. IMO you really should match your center to your LR, right now your not getting proper sound stage with a mismatched center. If your running a sub your speakers should all be set to small. You might look into running multiple subs or larger ones if your looking for "P.S. When I watch a bluray, Such as The Avengers, or Dark Knight rises, I aim for sharing my home theater experience with the neighbors on the backside of my property. I want to experience the Hulk, smashing." as you put it.

LOL! I knew by reputation it was loud, but I never heard it put that way before! http://www.avsforum.com/forum/155-diy-speakers-subs/2300554-nu3000dsp-fan-mod.html LOL you think the 6000 is loud you should hear the old EP2500 I had before, souded like a helicopter lifting off when it got going.

The new Reference series (not the premiere) are just painted/tinted poly cones. But they are the replacements for the synergy so lower end.

Thanks. The RF-35's were used as donors for the build, so the 8" woofers out of these went into the new build. They are the replacement drivers for the RC-7's and measure very close (within 1/2dB through the range) for the original woofer. I am still waiting on the 2 new 8" for the center, everything else is ready. Yeah that is a iNuke 6000DSP, it is currently running my JL 13W7 (seen on the left) and a near feild 12W7. I have a 2nd 13W7 that is also being used but I'm currently finishing the veneer on now. It has been fan moded and you can't hear it at all from 1' away.

Follow up on how the pair sound in place of my RF-35's. I'm in the middle of redoing my theater setup to more of a open space rather than the dark dungeon I had going on so it's a WIP right now. Watched American Sniper for the first time with these last night and They sounded fantastic, sound stage was far more dynamic and open. I tried them without the Subwoofers on and can say for sure they don't dig as deep as the RF-35's but with the crossover on and subs on it's a non issue. I cannot wait to have the matching center done and all behind a AT screen. And just to see how the crossover mods worked I one with a stock RC-7 crossover and one with my current modded RF-3 and the sounds is so much smoother, I think that is the resistor mod that everyone loves so much so worth it.

They both use the same size 1" compression driver but with klipsch the horn sizes do matter. This also applies for the tower speakers. I am not sure on the new rp line and the pictures seem to suggest the rp250c and rp450c share the same horn size while the rp440c seems to be smaller. If someone could elaborate on the horn dimensions that would be great. That's actually wrong the RC-52 and RC62 use different tweeters (there just horn loaded tweeters not CD's) the RC-62 has a much larger heavier tweeter. The new RP series seem to all use the same tweeter though.

What are you driving them with? Maybe you need more power like derrickdj1 said just, cleaner undistorted power.

If you can deal with a few dents in the dust cap here is one for less then 1/3rd the price of new. I bought the KF-87 horns off him and they arrived packed super well and work perfectly. http://www.ebay.ca/itm/Klipsch-RF7-K-1089-AV-10-Woofer-Dented-Cone-2-RF-7-/191791911639?hash=item2ca7b052d7:g:5UYAAOSwGotWposY

I am with you my friend, and I bet a lot of other people are too. I'm not tech savy enough to advise, but it's fun to watch you work. I have an idea for a "super center" as well, but I don't have the knowledge or equipment to make that happen. Seriously, even though you may think you are talking to yourself what you are actually doing is adding to the general knowledge of the collective. How cool is that. Yep that's why I said I would report back with the outcome. Couldn't wait so I put one together at luch, these will be using the woofers out of my RF-35's so I have to take one apart then assemble so I was only able to get one done. I lined the box with foam and a bit of poly in the top above the port and behind the CD driver, no poly behind the woofers only 1" open cell foam. So here is what it looks like compared to my RF-35, not near as deep but not tiny either. Agian don't mind the finish as this is just to see if they are actually going to work or not, also the angle on speaker is the basement concrete is super out of level. And a quick measurement, I placed my RF-35 center of my screen yesterday and took a measurement raw that is the purple line. And one today witht he new speaker in as close of spot as I could raised off the floor with a chair, the yellow line. Both 36" back, not sure if this is useful at all to anyone but to me it looks like a winner and should just get better with a little Audyssey action.

Ironman, the voices in that Blu Ray are messed up as well. Great movie great sound effects but not the dialogue.

Last update on this until I measure in room responce since I'm talking to myself anyway. LOL But I'll be sure to close it off with how it all worked out, or didn't. Braces in, the top is braced by the port as it sits tight against the sides. And one with it all together with a quick rolled out coat of primer, need to do a few more but shouldn't take long. The center speaker is all ready to brace up and put the front baffle on as well but no woofers yet.

Looks to be in phase with the mid, tweeter is out of phase.

Well you were the only vote other than myself. lol I decided to go with the MTM configuration but I could not center the layout, I forgot my new sceen wont allow the space to go below. :/ So here is what I ended up doing for the baffle layout, my CNC seems to have a messed up driver so I had to do these by had last night. I am 100% not a wood worker so don't judge. Took about 3 hours to cut all the boxes holes etc and put this one together to the point the front baffle and braces are all that are left, need to go get some foam to line them with before I can go any further. I will have a 2" wide cross brace front to back side to side on each side of the horn and on the last woofer, so 3 in total. I think that will be fine, about 6X what is in my RF-35. Ended up with a internal volume of 1.4 cubic feet and a port tune of approx 54 hz, don't mine the cutting mistakes I will be filling those when the box is fully assembled. Like I say not a wood worker but I am a Autobody tech so I fan fill/finish NP. How they will sit on the shelf behind the screen. Test fitting the Horn in And a comparison for the RF-7 horn and the RF-35 just cause I had it out on the weekend.

What program did you use on this if you don't mind me asking?

So thinking about it more I'm not 100% if I should be going with TMM or MTM, anyone have any thoughts on this? I had time at lunch to do up a few baffles , pretty simple since they will be out of sight anyway. These will be cut out on my CNC router, I can easily do the either of the first 2 and they would be fully behind my screen. If I go the 3rd option the bottom would be just under the screen, not a deal breaker but it wouldn't be as clean. Don't mind the blue cylinder in the pics, used my 3D printer slicing program for screen shots. lol Hopefully I can get a port designed tonight and on the 3D printer in the morning, going with a rectangle flared top and small flare bottom if all works well.

Little math and a multimeter might get you what your after. https://www.youtube.com/watch?v=Zq2goZXCbMM

Are you looking for max ouput or just output at a certian volume?

Decided a few weeks ago to try a build with matching LCR speakers behind a AT screen. Wanted to go RF-7's but they are just too large for my space and finding a used trio in Canada is pretty much not going to happen. So I have been buying parts to build my own in a size that fits my space better, here's what I'm working with. 3 - K-87-KV CD's with horns attached (ebay) 3 - RF-3 crossovers modded to RF-7/RC-7 crossovers (ebay) 6 - K-1122-OB 8" drivers which is the replacement for RC-7 8" They will be mounted on the wall behind my screen and ran with 3 subs so 80hz and below is not a concern with this build. Will be mounted upside down so the horn is at the base centered approx 38" off the ground. Dimensions will be 36" tall 10.5" deep and 10" wide wich gives a internal volume after drivers etc of 1.35 cubic feet, approx 47% larger than a RC-7 Will be tuned to approx 55 hz. Have the 8" driver measurements from the 120841 (RC-7) and the K-1122-OB driver (RF-35), WinISD has them within .5dB from 80 hz up. I'm guess the difference would be the test procedure I used to measure opposed to how the 120841 was done. I went with 3 RC-3 crossovers for a few reasons, I got all 3 as well as all the upgraded parts (new caps and resistors) for less than I could find 2 RF-7 crossovers. And I was planning to upgrade the pieces anyway so it seemed easy enough to just that right off. Few pics of the first one I built, if anyone sees anything wrong please post up and LMK as this is the first crossover I have ever touched. I have since put a few nylon tie wraps on the resistors to hold them to the top add on board. Took me about 3 hours from start to finish so I'm prety slow at this. LOL

Could not agree more, and yes sealed tiny subs for massive clean bass. I feel they were 100% the exrta I spent on drivers, they made my TC sound like a 12" lol

Your in Montreal? PM me info on the Heresy set if you don't mind.

WOW nice setup, The combo must sound fantastic. I had it in my mind to build a 212 clone when I built mine but they were just too big for the space I had. Went with 2 separate 13W7's and 1 12W7. Have to say the JL subs are cleaner than any sub I've had including the TC sounds LMS.

The RC-25 would match better and would be cheaper to buy, I have ran across a few on ebay resently for cheap. I have one sitting in my closet doing nothing since I bought it, but shipping to you would be killer. And yes the RB-25's are front ported so they can be wall mounted (keyhole rear mount) or tight to the wall on a shelf.

Non of the speakers I listed measure over 4ohms (3.5 re) so I would still guess the final load would be 4 ohms rather then 8.
