Ahhhhh!! Gotcha!! Thanks 😉 Looks great!! 👍

@Gbal4 the link expired before I got a chance to see. Reload it!! 😃

No problem and happy to help 😊 Yeah, old Carver A-500x. I have a ton of old Carver, Outlaw and Adcom stuff along with the Klipsch stuff. Too much!! I figured out one day that if I hooked them all together I'd have a 15,000 watt amp 😆🤣 I'm also working on a set of Not-your-Average Heresys with built-in powered subs and 80s vintage drivers and crossovers but those seem to always take back seat to an old Shovelhead chopper I'm building. Too many projects, too little time. ☹️ I'd do a build thread on what's gone into those Def-Techs but this is, after all, a Klipsch forum 🤣 I'll definitely do one on the Heresys though. Good luck with your project!!

May as well throw in this photo for grins. 😆 These are Def-Tech 10/10 IW subs in some steam-punk cabinets that aren't quite finished but I'm impatient so they're in use already 🤣 They shake everything off the shelves in the adjacent room so I have to keep them constrained 😂

Backside. I couldn't attach it to the first post 🤪

I do this routine a lot, so here's my suggestion~ Search ebay for your chosen driver by its original model name, R-12SW for example, and either buy a bare driver or one in a cabinet with a blown amp. Look up your T-S parameters here http://www.loudspeakerdatabase.com/ and use https://speakerboxlite.com/manufacturers/shared to get in the ballpark with cabinet dimensions. There are other tools available for project as well, but these are quick and dirty and quite close enough!! OR!!! Buy a Klipsch cabinet and go the other direction . . . replace the driver with something similar from the aftermarket. Dayton/Parts express has a ton of good stuff. I just finished a pair of R-100SW for a bedroom system using the last two Peerless by Tymphany SDF-250F75PRO1-06 on the planet (for the for-seeable future, at least) and they absolutely ROCK!! These were bare cabinets and I just blocked off the amp hole with a bit of aluminum diamond plate. That amp is an old LF-10 unit but they're being powered in the bedroom with a Carver M-1.5t Good luck, have fun, and I hope this is helpful 😊

@Audible Nectar ~ No tone intended, combative or otherwise, ☺️ I didn't consider your post as argumentative, and I'm sorry if what I wrote had you feeling like you needed to be defensive. That was NOT my intent!! I actually quite agree with your methods and approach, which is why it took me so long to find those guys in the first place!! 🤣 Deciding who's to operate on our beloved equipment isn't something easy or without anxiety, for sure. Paul and crew have earned my trust. There are certainly others that are as trustworthy, just as there are hacks and thieves. So, my friend, I think we're in agreement!!

There's one on eBay right now in decent shape for 1995.00. https://www.ebay.com/itm/134091546644?hash=item1f387aa014:g:xr4AAOSwktViXyds I have an Outlaw 770 and 950 driving five DefTech Mythos IIs that have been making happy noises for me for over twenty years in my HT along with a pair of DefTech 10/10 in-wall subs that aren't actually in the walls but in custom steam-punk cabinets (that I built) driven by either a Carver A500x or the M-1.5t that I'm having refreshed, so 5-channel stuff isn't on my radar at the moment. All my other various pre-amps and amps do 2or 3-channel duty in the garage or shop or the bedrooms and I'm always in the market for something new to play with. I have Bose stuff, Klipsch stuff (I'm building custom cabinets for some old Heresy drivers and crossovers at present), Sunfire and Carver, Soundcrafstman, Outlaw, Adcom . . . . . . I don't actually know how many I have!! It won't all fit in one room, that's for sure. I have better equipment in my garage than most have in their homes. 🤣 But to the point of this whole thread . . . . the guys at Atlantic are aces. I interviewed a lot of techs, including the so-called "specialists", before I chose them. They're the quiet, capable pros that don't engage in any of the "look at us!!" bullsh!t but do outstanding work at a very reasonable price because they love the gear. If the OP doesn't want to wait forever to get his gear serviced there are reputable, capable options out there. 😊 It doesn't really matter to me one way or the other. I have no dog in this fight and there's nothing in it for me but the satisfaction that I've been helpful to a fellow audiophile. On with the show!!

They work on anything, even if it's not on their list. I've seen Mac, Nakamichi, B&O and a host of other brands on carts or on the shelves. They don't care what name is on it, they love vintage stuff, and in actual fact they have one of my Carver M-1.5ts in their possession as I write this, waiting on a PCB for the meters. They also spent hours cleaning and testing my GFA-565 and gave me the diagnosis for only 50 bucks. I'm waiting on Hoppe's Brain to send a populated board to replace the poisoned one they found (a leaky cap fouled it and it can't be resurrected), and I'll be bringing it back to have them get it up and running once I have it in hand. I do know that they're reluctant to work on some Sunfire and Carver stuff depending on the year of manufacture, though, because of the notoriously low-quality heat-sensitive parts used (sub-woofer plate amps in particular), but they're worth a conversation. Great guys, they know their stuff, they're into Harleys, old cars and cool audio gear, and they won't break the bank. Good luck!! And if you're in the neighborhood give me a shout!! I'll show you some of my toys. 😆

I bring my stuff to these guys http://atlantic-systems.com/about-us/ if you're not opposed to shipping. They're not fast (faster than Bill though) but they're honest and good and easy to talk to. I can never get out of there in less than an hour once Paul and I get talking about "the old days" 🤣 They've worked on my Carver and ADCOM amps and I usually get them back in a month or so. They're local to me, sort of. Only an hour away. Give them a call. Maybe you can work something out.

I'm with ya. Heat is the enemy with both the driver and the amp on these. I have the amp in an open-back box, and so far the best alternative to the driver is a Peerless by Tymphany SDF-250F75PR01-06 10" Paper Cone Subwoofer, it having reasonably close T-S parameters. Nobody I've talked to is willing to replace the voice coil, I'm not at a high enough pay-grade to do it myself acceptably, and I'm still waiting to hear from Klipsch about a suitable replacement for the K-1073-K Driver. Oh well. We make do, yeah? 😁

Yo, Glotz!! I don't know how much you wanna spend but I just ran across this on eBay. Not quite as much ooomph as the original but it might be an acceptable replacement. https://www.ebay.com/itm/Klipsch-Subwoofer-Amplifier-SPL-120-Amplifier-Only-/284673824909?hash=item4247e1d88d Or this https://www.ebay.com/itm/Klipsch-SPL-150-Amplifier-1067491-AMPLIFIER-ONLY-/265577007452?hash=item3dd59f895c

Yeah, that's the general consensus. Anything built later than '99 isn't worth fixing from what I was told even before I talked to Bill about it. Nice talkin' to ya Glotz!! Good luck, and let us know if you ear anything new!! 🤣

Having re-read your query for suggestions I realised that I didn't really answer your question 🤣 I haven't actually witnessed this first-hand, but I'm told that a pair of SPL-150s are AWESOME to behold!! As in blow your hair back and rattle the walls. The C-310ASWi look like a pretty good approximation of the LF-10, albeit with a bit less power but a smaller footprint. I haven't auditioned those either.
