Craig6519 Posted May 2, 2001 Share Posted May 2, 2001 I can pick up a single KLF-10 with pretty bad scratches and no grill for $85, I was wondering If anybody ever thought about trying to build a center out of one of the legend series? Could I use all the existing components in the KLF-10 to make a good center? I pretty sure I could make a quality cabinet to house the 2 10's and the horn, Would this be a better match than say the KLF-C7? Or am I crazy to even think about It? Anybody have any thoughts/Ideas that would make this work?

boa12 Posted May 2, 2001 Share Posted May 2, 2001 craig, if your yammy has a rear center hookup that would work great, but i guess it doesn't. but yea I would think if you could build it the 10's horn(k) could be the better match to the 30s than the c-7's(kv). that'd be one big center.

Craig6519 Posted May 2, 2001 Author Share Posted May 2, 2001 Thanks for the quick reply Boa, I was wondering if the KLF-10 has everthing internally I need for a good center? Is there any kind of cross over in the C-7 that I need or would everything inside the KLF-10 work? Any Idea's? Craig Quote Link to comment Share on other sites More sharing options...
boa12 Posted May 2, 2001 Share Posted May 2, 2001 ohhh that may be best answered by the cross experts. sorry. just wanted to get in that rear center idea just in case. good luck... Quote Link to comment Share on other sites More sharing options...
4977 Posted May 2, 2001 Share Posted May 2, 2001 Craig, I called tech. service at Klipsch this morning To ask about doing the same thing with a KG 5.5. I was told that it will work with all the original components. How well it will work is another story. Keeping the internal volume of the new cabinet the same as the the original cabinet is necessary. You can however adjust the deminsions within reason. I was also advised that changing the driver aray could have an adverse effect on the sound. As far as the crossover question I was told that I would most likely. have best resluts using the 5.5 crossover. One thing working in your favor though is that the C7 & KLF 30 share the same tweeter diaphragm. Klipsch made no garuntee that it would sound good only that it is definately possible and may work out. Since I already have a KG 5.5 with a damaged cabinet I am going to buy a sheet of plywood and try to put it together this weekend. Good Luck, Q Quote Link to comment Share on other sites More sharing options...
Craig6519 Posted May 2, 2001 Author Share Posted May 2, 2001 Thanks again Boa, Anybody else out there in Klipsch land with any info? Will I need anything besides's the woofers horn and internals to make a good center channel? has anybody tried this is it even feasible? Any input would be much appreciated.

Craig6519 Posted May 2, 2001 Author Share Posted May 2, 2001 4977 I was typing my reply at the same time you made your post, It sounds like I might have a chance here!! Funny how we were both thinking of doing the same type of thing for our center channels. I really appreciate you reply it's answered alot of questions. i guess I can't go wrong for $85, Keeping that internal volume issue the same might require a bit more thinking. Thanks again Craig Quote Link to comment Share on other sites More sharing options...
PhilH Posted May 2, 2001 Share Posted May 2, 2001 Craig: It's not easy building a speaker, and not much easier modifying one like you are. It's tough to get all the variables covered and find the right combination that gets the best sound for the materials involved. Like our Tech Support people are saying "it's possible, but there are no guarantees..." One other consideration...you need to shield the drivers since the KLF-10 is not magnetically shielded...see parts on our website or call 1-800-KLIPSCH...and good luck with your project!

boa12 Posted May 2, 2001 Share Posted May 2, 2001 i just got done putting all the buck magnets on all the drivers in the klf-30s. let me tell ya that was no walk in the park for me. but the old sony tube is back to normal ------------------ Klipsch KLF 30 (front), KLF C-7, Cornwall I (rear) Velodyne HGS-18 sub woofer Monsterbass 400 sub interconnect & Monster S-12 cable Sony STR-DE935 a/v receiver Sony DVP-C650D cd/dvd player Sony Trinitron 27" stereo tv Toshiba hi-fi stereo vcr Technics dual cassette deck Technics direct drive turntable Scientific Atlanta Explorer 2000 digital cable box 2nd room: Klipsch RF-3 (front), RC-3, cheap little Technics (rear) Kenwood KR-9600 AM/FM stereo receiver (vintage '75) Teac PD-D1200 5-disk cd player Sega Genesis game player Sub: None yet rock on!

Craig6519 Posted May 3, 2001 Author Share Posted May 3, 2001 Thanks PhilH, Keep the info coming please. Boa do I need Buck magnets for all the drivers? Is this what shields the speaker? Please bear with me If I'm asking dumb questions here, just trying to get it all worked out. Thanks Craig Quote Link to comment Share on other sites More sharing options...
boa12 Posted May 3, 2001 Share Posted May 3, 2001 craig, i believe a more complete shielding is done by using both bucking magnets & shielding cups. i just did the magnets & did it for all as the tweeter & midrange were nowhere near as expensive as the woofers' & i did them 1st to see. but the bigger woofer mags were definitely more of the problem.

Craig6519 Posted May 3, 2001 Author Share Posted May 3, 2001 Boa, any idea how much money I'm looking at to completely shield a KLF-10? Thanks Craig Quote Link to comment Share on other sites More sharing options...
Jerry22m Posted May 3, 2001 Share Posted May 3, 2001 Craig With all due respect I think you would be crazy to think you could improve on the C7. The C7 was made to blend perfectly with the Legend Series what you suggest IMO would be a serious dowmgrade. GOOD LUCK. ------------------ Jerry Quote Link to comment Share on other sites More sharing options...
Craig6519 Posted May 3, 2001 Author Share Posted May 3, 2001 We'll Jerry22m, to have a set of speakers perfectly blend together theyed all have to be the same. I love my C-7 but think that having 2-10" woofs compared to 2-8' woofs would get It that much closer to running a full up front matching set. And I also thought for $85+ I couldn't go wrong even If It didn't work out. Craig Quote Link to comment Share on other sites More sharing options...
boa12 Posted May 3, 2001 Share Posted May 3, 2001 craig just the magnets would be a bout 1/2 as much as u paid for that 10 (bout $33 shipping included). the prices are listed on the parts list under home audio. ------------------ Klipsch KLF 30 (front), KLF C-7, Cornwall I (rear) Velodyne HGS-18 sub woofer Monsterbass 400 sub interconnect & Monster S-12 cable Sony STR-DE935 a/v receiver Sony DVP-C650D cd/dvd player Sony Trinitron 27" stereo tv Toshiba hi-fi stereo vcr Technics dual cassette deck Technics direct drive turntable Scientific Atlanta Explorer 2000 digital cable box 2nd room: Klipsch RF-3 (front), RC-3, cheap little Technics (rear) Kenwood KR-9600 AM/FM stereo receiver (vintage '75) Teac PD-D1200 5-disk cd player Sega Genesis game player Sub: None yet rock on!

decibel man Posted May 3, 2001 Share Posted May 3, 2001 Craig and 4977, first of all, if you go ahead with this project do not use plywood. You should use 3/4" or 1" MDF (medium density fiberboard) or some other sound deadening material. You may want to even build a small section for just the tweeter. Using a seperate box section for the woofers may help in the driver array problem, but it will be one tall center speaker. The drivers would be in a triangle array with the tweeter on top, picture a small rectangle on top of a large rectangle. It is a tough project. You are going to have to figure out where to put the wide flare port so you don't have increased bass distortion. Tuning a box is pretty tough. I just built a pair of speakers for my workshop. I had a couple of RF-3 drivers that the movers has slightly damaged which were replace at their expense. I easily fixed the damaged drivers and used them in a pair of speakers I modelled after the RB-5's. I used pre-assembled crossovers and Selenium horns (low cash). It was about $200 and a lot of sweat and blood to get it right. They sound good, but they are in my workshop, not in a listening room (thank God). You guys are taking on a bigger project. I think the center channel speaker is probably the hardest speaker to make, let alone tune. If you guys go ahead with this project, I wish you the best of luck. Be sure to keep us updated as to how it is going. Good luck and enjoy! JT Quote Link to comment Share on other sites More sharing options...
Craig6519 Posted May 3, 2001 Author Share Posted May 3, 2001 Thanks again Boa, What else besides the magnets will I need to shield the speaker? decibel man, I hadn't thought of setting up the speak with the horn on top,I was gonna do It In the same layout as the C7 but your Idea sounds even better. As far as tuning the box I have no idea as I've never took on such a project. Any more info would be appreciated. Craig Quote Link to comment Share on other sites More sharing options...
boa12 Posted May 3, 2001 Share Posted May 3, 2001 the other thang be shielding cups. don't know much on them as haven't tryed those. Quote Link to comment Share on other sites More sharing options...
Craig6519 Posted May 3, 2001 Author Share Posted May 3, 2001 Boa, Are the cups to shield the Horn? Craig Quote Link to comment Share on other sites More sharing options...
4977 Posted May 3, 2001 Share Posted May 3, 2001 decibel man, I asked about placing the tweeter above the woofers like you suggest. I was told that it would probably be best to keep the voice coils on the same axis. As far as the port goes I don't have a clue as to how to determine the proper place for it. I have thought about using two 2" od 4" long tubes on the ends of the speaker similar to the KV3. I haven't decided for sure about that. I have been thinking about using MDF but the main reason I thought about was cost. I agree that this is a big undertaking, especially considering my lack of knowledge in speaker design. I have decided that even if it doesn't work I will only be out a small amount of money and a lot of time. Of course if it does work I will have an incredible center channel for basically free. As far as shielding goes I placed two of the woofers directly on top of my RPTV and saw no difference in picture quality. If the speaker sounds good I will buy the bucking magnets just to be safe.
