Well I can call this project done. Grills and name plates done. Thanks for all the help along the way, I learned a lot being here.. Lonny

Hello Good People; Well I had another deal for said tweeters (model 23 or equivalent) fall apart, so I will ask here, do any of you fine people out there/in here have a working set for sale. let me know.. Lonny Thanks

i got my crossovers finished and switches installed but still looking for Model 23 (or equal) tweeters to finish off this build. Lonny

Happy whatever you all celebrate, I am glad I found this site, the information here is invaluable Thanks to all that helped me through my stuff.. Lonny

Thanks dxho, I am aware of these other tweeters I could use, when I say I'm looking for model 23 tweeters I am looking at all options just none have come up for sale yet ,That is why I went with a phenolic tweeter until I find the correct tweeters, I am still waiting on my crossover parts to build the 23 crossovers..... https://audiokarma.org/forums/index.php?threads/klh-model-23-dimensions.939140/page-2 Lonny

Hello All, I carried this thread over to AudioKarma https://audiokarma.org/forums/index.php?threads/klh-model-23-dimensions.939140/ But am still in search of Model 23 tweeters to finish this build.. Lonny

Hey Tommycat, The Five, Twelve and Twenty Three use the same tweeter . I am also looking for a pair ,there was some on Epay a while ago and I was negotiating for a pair locally but that deal fell through so I bought a pair of phenolic tweeters to fill the hole until I find the right ones for my "23" replica build seen here.. Good Luck... https://audiokarma.org/forums/index.php?threads/klh-model-23-dimensions.939140/ Lonny

Hey guys, I know mine came out of a model 5 and were listed as 12" but after receiving them they measure 10.75" I was just curious if they made a 10" and a 10.75" I am still looking for the inductor size mH. of the model 23's.. Norman look here and here to see what I am up to. https://community.classicspeakerpages.net/topic/12454-more-bass-bottom-end/?tab=comments#comment-132582 https://audiokarma.org/forums/index.php?threads/klh-model-23-dimensions.939140/ Lonny

Hello all: Are these two different speakers?? model 5- 12- 23 list a 12" but on measuring the woofer is 10.75" What's up KLH... Lonny

Hello all: I hooked these up and was not disappointed with results, I have no scientific way of measuring them, just my ears and brain, and my brain said wow! Once I get the surrounds doped they should get better according to most everyone on here. Now my dilemma these are too nice to just be subs, so I am bidding on some model 23 tweeters to finish this build and turn them into replica 23's (for the basement) but I need a little info, measurement's to cut the tweeter holes (top to middle of tweeter and side to middle) and numbers (milihenry's) for the inductors, I have the numbers for the resistors and cap along with a diagram So any "23" owners out there please feed my addiction.. Lonny

Finally, got my baffles back, never tell a worker "No Hurries". Installed 24 oz. of pink insulation as per Ligs and kent's recommendations ( averaged ) got the grills cut out but am still waiting for the cloth to cover them . don't have time today to hook them up . Lonny

Hey all: got the crossovers and terminals installed today along with a few hours of wax on wax off they are really starting to shine now. i should get the baffles back on Tuesday to complete this project. Lonny

Hey Guys: Thanks for the tip about the XO's, I am planning on mounting them inside but will have access to them if they need tweaking. The gold oak on birch looks great when it is still wet, but dulls a little while drying so today I will try furniture wax and elbow grease. I still have to get the pink insulation stuffing and 1/4" hardboard for the grills, the grill fabric is in the mail and is coffee colored to match the CB-10's and baby Advent's. I am still waiting on a backordered amplifier (200 wpc 8Ohms)to power the AR's KLH's and Advents then these woofers will get the Peavey IPS150 75 wpc. Lonny

Hello good people: I am making progress on this project now that I have (almost) everything in hand, there are no before pictures of the speakers because all they were was a pile of plywood pieces not photo worthy. A picture of the KLH model 5 woofers with the new low pass filters and spring terminals from my baby Advent II tune up. The cabs were made of 3/4 inch Baltic birch because the available oak was crappy looking, so Baltic birch with 3 coats of golden oak stain. I sent the baffles back to the carpenter to have the rabbet joint cut around the hole for the speaker inset. not much else I can do until I get the baffles back . I have ordered surround sealer from Vintage AR as mine look to be very porous, judging by the flashlight behind the speaker test.. Tomorrow some waxing and buffing and maybe install the lowpass filters and terminal cups.. Lonny

Thanks ligs: The cap looks too new to be factory so they might have been added by the previous owner. Lonny

Hello Speaker freaks: I received my KLH 5 woofers (and xo's) today, checked the VC's 4.1 ohms ,frequency sweep from 0 to 1000 sounded smooth . These speakers look new except for the sloppy re soldering job. These cones are the thickest and stiffest material I've seen. Looks like the cloth surround's and dust caps need to be resealed . Ok now for the questions, the speakers came with 5 Mf 15v caps soldered across the + - terminals, as I am not using the KLH 5 crossovers should I keep them or remove them ??? I will be using off the shelf lowpass filters 350 hz 12 dB slope. I had to drop my wood at a cabinet maker to get cut because I don't have the tools or room to cut a 4x8 sheet down, I should be able to pick it up next week. Till next time... Lonny

Typo Try Sony hap-z1es Lonny

Thanks Kent, The AR3a box is verrrry close to the AR1w box and mine will be the same dimensions as the AR1. I read that the AR1w box " was filled with fiberglass" but no numbers ? So now I have a number to start with. I have not read all of the AR3a Restoration guide but will .. Lonny

What have I got myself into, woodworking and MATH! two of my least favorite subjects, but I am a details guy so I know the results will be exactly what I am looking for. It's snowing here again so just about time to turn the heat on in the shop and get to work. Ligs I read your other post and I have a question for you or anyone, is there a formula to figure out how much fill to use in each box?? more to come... Lonny

Hello All: After reading a lot about the AR-1W I have come to the conclusion that I need them (but not for a $1000+). I have my KLH 5 woofers and crossovers being shipped as of yesterday . All the reading I did on the AR-1W and KLH 5 I found the boxes to be very close in size, 130 cubic inches (2.1l ) difference to be exact, So I decided to replicate the AR-1W boxes with the KLH 5 12" woofers and some form of crossover/lowpass circuit ( the AR-1W was low passed at 600-650 hz) I should have my wood cut (3/4" oak to match everything else) before my woofers get here pictures will follow... Lonny

Hello Kent: I was not aware of the AR-1w, but after reading this http://acousticresearchspeakers.net/2016/10/acoustic-research-ar-1w-loudspeaker-single-lacquered-walnut-finish-sn-09697-2/ It gave lots of technical numbers for the speaker and the box, I like it. IT gives me another way to go , I'm looking for a winter project (we already have 4-5 inches of snow). Being in northern B.C. Can. KLH fives are hard to find, and if you do find one(two) they are $800-$1000 pr. I've priced out KLH 5 woofers, mids, tweets and crossovers and I could build one (two)for far less. The Dayton kits look interesting in a 15" or 18" I saw an ad for the AR 1w $2500 a pair WoW. I'll keep posting my progress.. Lonny

Hello good people: My CB-10's are the biggest woofer I am running right now (along with baby advents and AR 102's both with 6.5" woofers) but feel I need a little more bottom end bass , and after scouring ebay and other auction sites I see I can buy all the drivers I need to piece together a decent KLH system, model 5 12" woofers mids tweets and crossovers cheaper than a complete speaker set.. DO any of these companies (AR Advent KLH etc.) make a stand alone sub??) What makes these speakers so good ?? the drivers the boxes etc, I should be able to make a exact copy of a speaker box and if I use factory drivers and crossovers would it not sound the same? What are you guys (girls) doing for more bottom end? Lonny

Hello all: I received my baby Advents on Friday and I am pleasantly surprised by the near mint condition of these speakers , people really do baby their baby's. Replaced resistors and capacitors on the crossover boards then swapped the boards to the new binding posts, simple swap and the holes all lined up on the new cups, nice. I am amazed at the BASS these little speakers put out . As others have stated in other baby Advent posts the corners of the tweeters always break off as mine did as soon as I removed one (the other was cracked but did not break off) Simply Speakers has this tweeter in stock so I might order a pair. pic. with the green cap is the old XO and spring posts, pic. with the Dayton cap is new resistor + cap.+ binding posts. Lonny...

Thanks Kent, I looked on Audiokarma but did not see that post, So I will wait patiently for my speakers to arrive. I will change out the spring connectors for some binding posts and replace the crossover components for solens. I think these will look good with the CB-10s. Lonny

Yea I get it, I was trying to get an order placed to have the parts in hand for when they arrive. They should be here early next week . Thanks again RTally Lonny
