stoka Posted October 13, 2017 Share Posted October 13, 2017 Hy guys I have a question about the Klipsch RP-280F. I searched now a lot but didn't found any describe or anything else, how I can open the speaker. I hope somebody has a n idea, or even better some pictures or description. Why I wanna open it? So, I have actually the RP-450C as center speaker and its really a great center for movies. But... when I'm listening multichannel music, I hear a difference between the center and the fronts. It's simply not the same and I'm very for this equality thing. It's hard to describe, but I simply would prefer the same speakers for LCR. So the idea is to buy and open a third RP-280F and make a new frontplate for it, to set the horn in the middle and the 2 8" left and right of it. I have found in the internet some topics about a modification of a RF-7 II as center, so that's what i planed to do with the 280. 1 Quote Link to comment Share on other sites More sharing options...
dtr20 Posted October 13, 2017 Share Posted October 13, 2017 I believe the cabinet is all glued together, so you would have to unscrew to remove the woofers, the horn, and crossover terminal cup on the back. I think this is the most they come apart without unglueing the cabinet panels. Quote Link to comment Share on other sites More sharing options...
thisgsx Posted October 13, 2017 Share Posted October 13, 2017 I agree with the OP. The 450c simply does not match the rp-280s. The 450c sounds way too small and thin compared to the 280s. Best to probably build a custom center utilizing the same drivers and crossovers from the 280s.Sent from my LG-LS997 using Tapatalk Quote Link to comment Share on other sites More sharing options...
dtr20 Posted October 13, 2017 Share Posted October 13, 2017 I believe center channels have a different style crossover to prevent lobing(?) since the speaker is on its side. @MetropolisLakeOutfitters can explain it better. 1 Quote Link to comment Share on other sites More sharing options...
stoka Posted October 13, 2017 Author Share Posted October 13, 2017 thank you all for your fast answers! And yea, it's like thisgsx said, I can just hear out, that the center is too small for the fronts. But as I said only at music. If I would use my system for 100% HT, I think there wouldn't be so much a problem and I would let it like it is. I also thought that the front is just glued. My idea is (I think it would be the easyest way) just to remove the front panel and make a new one for the other positions. The rest of the cabinet i wanted to let like it is, so that there is not so much work. I never builded a complete speaker by myself. I would like to, but as I'm living in a normal apartment with family, there is no space for me, for such a big project. But just to change the frontpanel should work I think. Do you think, this would work like that? Quote Link to comment Share on other sites More sharing options...
rebuy Posted October 13, 2017 Share Posted October 13, 2017 Turn the center OFF when you listen to music. that will solve the problem and probably sound much better. Quote Link to comment Share on other sites More sharing options...
stoka Posted October 13, 2017 Author Share Posted October 13, 2017 That's what I'm actually doingt, but I would like to be able to hear music in multichanel;-) Quote Link to comment Share on other sites More sharing options...
rebuy Posted October 13, 2017 Share Posted October 13, 2017 I have a 5.0 system--for Music I turn off my center--to me, it sounds better. So for music I use Two Mains and Two surrounds. And I have a very large center. Quote Link to comment Share on other sites More sharing options...
The History Kid Posted October 13, 2017 Share Posted October 13, 2017 What you're describing is the homemade "RC-7 II.". There is a build on the forum for it. You'd be better off building it from the ground up or leaving the tower as a tower. Quote Link to comment Share on other sites More sharing options...
Paducah Home Theater Posted October 14, 2017 Share Posted October 14, 2017 Just run a third vertical one if possible. The "custom center out of tower components" has its ups and downs. Midbass is great but if that design made for a great center in general, they'd just make one like that from the factory, no? Big woofers spread out pretty far and crossed over pretty high makes for lots of lobing / comb filtering issues. 1 Quote Link to comment Share on other sites More sharing options...
stoka Posted October 14, 2017 Author Share Posted October 14, 2017 That would be of course the best option, but as it's in my living room, there is no chance with the space... I have actually a lowboard with the center on it and the tv above. So there is no way to put a third one vertical in the middle. Now the first point is a new lowboard. I think when this is finished, i will just look for a used 280F for a good price. When I find one, I will just buy it and try. If it sounds complettly bad or even worse then with the RP-450C now, then I have at least learned something ;-) Quote Link to comment Share on other sites More sharing options...

stoka Posted October 16, 2017 Author Share Posted October 16, 2017 Yea, you will laught, but 3 weeks ago, there were 2 here for around 300 Dollar each, but i went on holidays, and now theyr'e gone... But maybe i will find also a pair for a good price, where one of them is a little bit demolished or something like this. I will see, time is not running out at the moment. 1 Quote Link to comment Share on other sites More sharing options...

stoka Posted March 7, 2019 Author Share Posted March 7, 2019 Of course. I have hooked it up yesterday and I think it will stay. The "sound"-difference compared to the RP-450C is not HUGE, but audible, so I've got what I wanted, the est matching center for the RP-280F's. The biggest difference are the vocals, which are now a bit more voluminous and it just sounds a big "bigger" now. It's hard to describe. I mean, the 450C is a really great center, but this one makes some thinks just a little bit better and sounds a bit more like "big cinema".

Hunter Posted April 7, 2022 Share Posted April 7, 2022 @stoka I was so glad to come across your post here. I found a 280f online for $259 and jumped on it for exactly this reason. How is the center channel treating you now? I have removed the components and the next step is to get the face of the speaker off… any advice before I pull out the circular saw?
