Yup, the xover is in the "can" with the input terminals attached to the woofer frame. It it odd that they'd offer a coax driver, it's obviously factory as it has the PWK label and the blocking-board over the regular horn openings looks factory. Gonzo, have you hooked 'em up yet? I wanna hear those if they play... Todd in Beerbratistan

Ouch! My go-to is New Glarus Brewing Co's Spotted Cow, which is a farmhouse ale. Even has a touch of corn in it! Nice bite, not too bitter. Russ...still enjoying the '75 Heresies? Todd in Beerbratistan

Heya, A friend of mine found a pair of H-WO 12 at a thrift, the serials are #289 and #290. They're smaller than the 1975 HWO's I had, and the slots for the tweeter and narrow-horn squawker are blocked off inside. The driver is a PWK-labeled Jensen AlNiCo coaxial unit. He had just found them when we ran into each other this afternoon thrift-diving, so no idea if they play. My jaw dropped when I pulled the back off of one of them and saw that coaxial, though! Any idea what year these are, and if the "12" designation was for a coaxial-loaded HWO cab? Many thanks, Todd in Cheesecurdistan

That's the man I got my diphragm from. The link I posted is to one of his auctions. Straight up guy and very helpful. If I needed more diaphragms I'd get them from him. TP, still lovin' his '75 HWO's....

Your tweeter diaphragms are most likely toast. They're still available though, I bought mine from an eBay seller. Measure the DC resistance of the tweeters (disconnect them from the crossover first) with an ohm-meter. They should read around 6 ohms or so. I bet they're open...they're pretty robust but abuse will do them in. The seller I bought mine from has K77-M diaphragms for $62.99 for a pair, a bit steep but he does ship fast. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3074431741&category=14993 TP

Got the 9191 for $125 (BIN). It has all new belts and rubber, had all its mechanisms and controls cleaned and lubed and has had a few caps replaced as well...seller had a technician go all through it. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3045915034&category=4784&rd=1 A tube amp would be fun to play with...but I'm usually one to keep the tubes in the musical instrument amplifiers and out of the hi-fi, but that's me. I did have a Scott Stereomaster 222D once...was a fun piece. Bought for $10 at a flea market, sold for close to $200 on eBay. Anyway... Dang I love these speakers! TP

Oh man...it sounds gorgeous. Wonderful. No harshness or graininess...almost brethtakingly lifelike. And I don't have much into my electronics either, I've gotten into collecting and restoring vintage Pioneer receivers and so on...running a nice 1978 SX-780 (which, despite having oft-derided STK IC outputs, is incredibly smooth, handily trouncing the all-discrete later 1992 Denon that it replaced). My 1977 SX-450 (15 w.p.c.) sounds wonderful through them too, though the 450's now in the bedroom. I'm lovin' it!

It's a fairly simple repair, but you do need to work carefully and slowly to avoid accidentally ruining the new diaphragm. I have to laugh, I paid for for the diaphragm than I did for the speakers! LOL TP

Wellp...finally got the new tweeter diaphragm for my 1975 Heresies. I installed it this morning. Finally they're both working as they should. Sat down to listen...wow. What a lifelike loudspeaker these are. $15.98 for the pair...$25 or so shipped for the diaphragm...around 41 bucks into them all told. I'm jazzed. TP

Aw man...someone beat my cheap Heresy score, and didn't have to get a new tweeter diaphragm either! Good goin! Gonna refinish those puppies? Todd, anxiously awaiting his new diaphragm so he can make his Heresies sing

I find the bottom to actually be quite pleasing. I live in a small apartment, and the other loudspeakers in my main system were Polk Monitor 4a's. Back in Michigan I had the Magnepan SMG's which aren't known for LF extension. They didn't have a lot of bass, but the bass that was there was very accurate. The Heresys seem to be quite accurate down there too...whether it's an electric bass, an acoustic upright bass, or left-hand/pedal B-3 organ bass, it sounds right. They don't sound overdone at all. Some say the low end of the Heresy is a bit on the thin side...but compared to the little Polks I've been listening to, they're a step up. Once I get the other tweeter tweeting I'll really be able to sit down and critically listen to them. I've got a feeling these are loudspeakers I could confidently track and mix on. Todd P.

Woohoo.... My replacement diaphragm's on its way tomorrow...so it should be here in a few days...I'm stoked! Can't wait to get it in there and really sit down and listen to these puppies. They're hooked up and playing more or less for background racket, and the working drivers are putting forth a 'presence' I haven't had out of a speaker. I used to have Magnepan SMG's and loved them, still am partial to that maggie sound, but there's an immediacy to these Klipschs that is apparent even with one tweeter out. But they're not the least bit harsh. I'm gettin antsy TP

Gonna order the new diaphragm Monday. I have them hooked up and playing anyway, just for grins. The fully-working one sounds solid, and the 2 working drivers in the other one sound solid. Even with one tweeter out I can tell these things have some magic in 'em. Looking forward to fixing that tweeter...can't wait! No rattles, buzzes, or honks at all. Grills on, grills off, and one speaker in front of the hi-fi/bookcase mess. TP

Hehehehehe Can't wait to get the new diaphragm These are keepers, methinks. TP

Hello! (first post here) I was crusing the Goodwills today (I often find good vinyl for cheap at those places) and happened upon a fresh cart of stuff headed for the appliance section. I saw two wood boxes, dug 'em out, and about had a heart attack. A nice pair of Klipsch Heresy speakers (I'm told they're 1975's) for $7.99 each. Cabs have some dings, but the drivers looked perfect. Triangular PWK logos on the grills were intact, too. Got them home, they work perfectly except for one tweeter is inoperative. I'm in the process of obtaining a replacement diaphragm. Aside from the bad tweeter, they sound wonderful. Even with a low-wattage vintage Pioneer SX-450 (15 wpc) the sound is clean, effortless, and dynamic. Just need to fix that tweet to get the upper couple octaves in the other channel, and they'll be singing. They're both super clean inside, they look almost new. A bit of TLC to the cabs and they'll be looking very nice outside too. I've never owned Klipsch speakers before (a good friend has had KG4's for years, I always liked them) but these bargain Heresys will probably make me a convert. Todd P
