this woofer wrong for khorn need Fs low twenties 4 ohm K-33E is good for application mccauly is for musical instruments w/Fs 40Hz carbon fiber cone is good for horn loading high magnetic field is good for horn loading

Colin, that realy cool place was called Tech Hifi located at MIT and Harvard Sq. in a place that is now a yuppified teen mall. I worked there part time 77-79 while going to school there. Commission only. Tweeter was on the other side of the Sq. on Mt. Auburn St. Tech sold all high end stuff for the time. Big McIntosh and JBL Pro dealer. Place was always busy, always made money, badly managed.

i have a pr. of T-350s w/k-horns. I think they're ok. efficiency is ~106dB/W/m. I'm not sure I'd pay $400 for them.

sure those baskets are stamped?

those Empire speakers with plastic enclosures that resembeld buckets with the downward firing woofer--came in white, blue and red.

Hmmmm- Here's a picture of a K-33, labelled such on the mounting flange. The K33E designation is on the magnet. This came from a 1982 K-horn. One speaker, both designations!!!

cement makes a great horn material. packing an aluminum or polymeric horn in cement is a BAD idea, the cement will separate from the horn

Guy-Patrician bass output is impressive, organ pedal notes are reproduced with real weight. Down side is that it is a 4-way configuration a real pain to network. Need a decent mid-bass horn and complex CO network.

don't get hung up on wire---just get OFHC grade copper (Carroll and Belden makes it to the ASTM specifications).

call klipch at 1-800-BEND-OVA for a replacment.

Q-man, My Patrician plans came from Oct 1955 Audio magazine article written by Roy Allison. Very well detailed and includes a step by step procedure. I built the unit detailed in the article and used EV 18WK bass drivers, no decorator cabinet, utility look only. If you have different plans, lets copy and swap. Send me address off-line, I'll reply. Regarding construction, It is my opinion that the Patrician per the Audio mag plans is easier to build than the K-horn per factory plans. Also, high end roll-off of the Patrician starts around 250Hz, 3-way will leave a hole in the response unless you go horn loaded cone for mid-bass. LaScala atop Patrican folded unit?

John A-The bass horns were shipped in the "KD" configuration, nothing special to look at. Recently, I've developed a exponential mid squawker horn cast from ultra fine Portland cement. I'm modifing the design to minimize the cement usage. Total weight is only 70lbs. Compression driver is the stock OEM but any 1 3/8" can be substituted. Listening tests made the effort well worth the work! I will post pics when complete. Reagarding the network, I swapped out the caps (Holivand) and the coils (Solen). Also, I mounted the components on a larger board given them greater nearest-neigbors distances than OEM spacing. The sound improvement was significant and IMO superior to OEM unit. The AA-network has been around for a long time, works well with the K-horn and PWK likes it. I can't say if Al's design brings more value to the table than a "hot-rodded" OEM unit. For my ears, I know for a fact that premium hardware improves the stock AA unit so dramatically (repeat 3X) It should be a standard mod for anyone serious about listening to music accurately.

tomd--thanks! the horn is fabricated using end-grained joints, they must be prepared prior to joining or else the glue will be pulled into the plys and away from the joint. The end-grains are first painted with a thin coat of hot animal glue. the low viscosity of the hot glue penetrates about a 1/16" deep into the end grain. once dry the mating panel is then fitted, pilot holes and c'sinks for screws properly located then drilled. for assy, the mating panel is "primed" with stainless steel sheet metal screws, a heavy, continous bead of glue applied, panel is set and the screws are driven. No caulking of any type is used, the excess glue is allowed to just squish out. The woofer chamber looks like a bead of caulk was applied, actually I just ran my finger around the woofer chamber joints to keep those surfaces clean. I made these units for someone else, the woofer chambers had to be clean. You right about the DIY thing, you must have a good table saw and soem decent tools. I've got an old Tannowitz Variety Saw, makes a Powermatic look like a toy! John

rowooo-thanks, i've made many over these so a bit straight fwd. key is assembly sequence, if sequence is wrong you end up with gaps and misfits. precisely machined parts is good start but if assy sequence wrong-->gaps!! i've made University Classic, University Dean, EV Patrician and Klipschorns, its fun, keeps me sane and only real cost is the plywood. It takes 2 sheets of 3/4" and 4 sheets of 1/2" premium birch ply, about 500 screws and a quart of glue to make a pair of K-horn bass horns, or about $200 each.

we roll our own here

"Laugh-at-it" was what it was referred to elsewhere.

When I think of well run companies that use the internet effectively for sales Apple Computer is not the first company that comes to mind. 1D / 5D / 1M / 6M / YTD / 1Yr / 5Yr

Clarion brand car audio amps have parts sourced from Binghamton plant.

a couple tblspns of grated soap in a pint of turpentine. soap improves wetting action of turpentine and reduces work. soak rag (not sopping), lightly rub, repeat, work the whole surface until it brightens. when done you have to remove soap residue so finish wipe with turpentine only. if it still looks swirled, try again, if after two attempts, and still looks bad, I'd say re-veneer. if not experienced working with flammable solvents, better to re-veneer, sand and re-stain. khorn is large and ventilation is important--->not worth having a house fire over. also, check out ingredients of Scott's Liquid Gold, it might be turpentine based, if so I'd just use that.

I don't know what Scotts Liquid Gold is but I use Fels Naptha (soap) mixed with turpentine to clean oiled finishes. Clean and let stand about a week, then oil, then bees wax. The amount of crap it takes out of the finish will blow your mind and the venner really brightens up. Real easy to do but the rags are flammable so don't leave them lying around, let them dry out.

The largest McIntosh dealer in MA found out about the McIntosh sale to Clarion a week AFTER it happened which was two weeks before it was released officially to the media.
