Playing around using the driver I can see, keeping the old cabinet and building on to it sounds like a shack, and not even the Radio kind. I don't see why you would need more bass, always at the cost of some other quality, from all of your speakers. You only need ONE good source of bass per room, maybe even per house given the way bass carries. My own view is that nothing beats a purpose built bass speaker. Pick a design and make one.

I think if you have some good local help, anybody with the bare minimum of electrical and hifi knowledge, you could quickly sort this out, and from reading the whole thread I have some concern that without that help some type of accident is likely. Your receiver shutting down sounds to me like some kind of protection circuit is operating, and you don't really want to repeatedly rely on it saving you from more serious trouble. Things I think need checking; AC wiring to all devices, and the outlets and household circuits being used. Verify all in good condition with no overloads. Check each device on its own for proper operation.

I'm not a big switch fan, and like to keep stuff simple, I would use a patch bay with one section RCA and one section banana plugs. OTOH I don't think I agree with the basic premise of periodically turning on electronics to keep it in good working order.

Who would guess a company best known for 99 cent cigarette lighters wouldn't make a cheap quality subwoofer? BIC as long as I have know them has been a low cost low quality brand. OTOH while I doubt 4 of them would be impressive, 16 or 32 of them might be.

Building a sub is an excellent first speaker DIY project, its a box with a hole, nothing simpler, except maybe a tube with end plates. Improvements are more a question of what you want, ability to customize the design, but I suspect you don't have to go far down the road to improve on building quality just by using better materials, heavier panels, more bracing etc. than is practical in a consumer product.

Orange county is lucky to have a number of good speaker repair shops, but quality issues and price are not making reconing very attractive options with the K-22. Fixing rotted foam is the bread and butter of speaker repair shops, and the Klipsch are long lasting paper, new K-22 are not expensive, so we end up with the chicken and egg, few are reconed, low volume drives up cost and reduces quality, which further reduces volume. OTOH with shops local I can drive over hand them the driver, and inspect it when its done, and maybe even get a deal as a local. I think recone is currently my third choice behind find a good original, and find a good upgrade. Speakers are now sitting on a table in my garage, wow, not light weight and barely fit in my trunk, but still smaller than I imagined. Tomorrow morning I hope to do some quick testing, make sure the rest of the diaphragms are in good shape etc, then attempt some patience to see what turns up in woofers. I'm surprised that some of the quality cast frame 12" drivers haven't been tried, Altec and JBL. *** BEC drivers are in the running, but I usually have a strong urge to try something different with upgrades.

I've read the first link, second one is going to take some time. Having fun is the easy part, all I have to do is hide them from my wife. I was hoping to hit the ground running, have some replacement woofer ordered before I pick the speakers up, but I think I need to give some thought to the direction I want to take. Its a bit disappointing that nobody recones the originals. Thanks, more after I have the speakers in my hands.

I'm a long time Klipsch fan, and tonight made a last minute bid on a pair of Heresy HBR on ebay with kicked in woofers (movers according to seller). K77, K55V, K22, with a type E crossover. Cabinets are a bit rough, but looks like mostly cosmetic damage. One woofer I think I can repair the 2" tear along the surround, right at the junction of the wiggly part, but the other is torn away a couple inches around the voicecoil and all the way to the surround and a few inches back. Initially I'd just like to get them working as original. Long term, I expect I have been biten by the horn affliction, and will spend the rest of my days fiddling with horns. I like what a subwoofer can do when crossed electronically to mains between 80 and 120 hz, so I am thinking about replacement woofers that would be optimized for 70 hz and up. Goal would be to bump up the efficiency a bit, but also sound quality issues are important. Any suggestions, anybody try this? I'm in SoCal not far from Disneyland, so a local or semi local inexpensive source of a spare K22 or two would be good too. Thanks, looks like a great forum.

What about a cross brace that instead of going panel to panel in wood to wood connection, put a compliant vibration damping material between the brace and panels?
