Catbo Posted April 15, 2008 Author Share Posted April 15, 2008 Wow he's got lots of drivers going on there , but there's something about your design that's got me Wow, thanks !!! [A] Quote Link to comment Share on other sites More sharing options...
Catbo Posted April 15, 2008 Author Share Posted April 15, 2008 Do the goldwood horns have to be adapted to receive the Atlas PD-5VH midrange driver? Yes, I used an adapter for a 2" throat bolt type to a 1" throat for a 1-3/8"-18 TPI screw driver. It's just under 1 1/2 inches or so and cost around $6.00 to $7.00 each and "made in china" The guy I bought them from purchased them for that price at a local PA Systems/Audio store. It's made out of aluminum and has a nice black satin finish/paint. Quote Link to comment Share on other sites More sharing options...
GaryO75 Posted April 16, 2008 Share Posted April 16, 2008 Catbo, Can you supply an address, phone, or e-mail address for the adapter supplier? I have the Goldwood horn, and was looking for that type of adapter. Any source information would be appreciated. Thank you!! Gary Quote Link to comment Share on other sites More sharing options...
dmonte Posted April 16, 2008 Share Posted April 16, 2008 this is the only adaptder that I found but according to the reviews it doesn't look too good they have another adapter that's made out of aluminum but it's male. http://www.partsexpress.com/pe/pshowdetl.cfm?Partnumber=264-322&FTR=264-322&CFID=23475959&CFTOKEN=71654560 Quote Link to comment Share on other sites More sharing options...
GaryO75 Posted April 16, 2008 Share Posted April 16, 2008 That adapter is designed to connect a threaded driver on to a flanged horn, but with a 1" throat. I need to go to a 2" throat. Quote Link to comment Share on other sites More sharing options...
dmonte Posted April 16, 2008 Share Posted April 16, 2008 Gary the Atlas driver I believe has a 1 inch threaded male end correct? that we need to adapt to the horns 2 inch opening and flange. I believe we need a female version of this one that is cast aluminum.not the flimsy plastic one. http://www.partsexpress.com/pe/showdetl.cfm?Partnumber=264-323 Quote Link to comment Share on other sites More sharing options...
GaryO75 Posted April 17, 2008 Share Posted April 17, 2008 You're right. The adapter needs to be female thread for tha Atlas driver to connect, and a 2" throat for the Goldwood to bolt up. The Goldwood has a 4 hole configuration on the mounting flange. Quote Link to comment Share on other sites More sharing options...
Speedball Posted April 18, 2008 Share Posted April 18, 2008 Those have a beautiful finish..............Nice woodworking skills too with all the screws and no glue. Quote Link to comment Share on other sites More sharing options...
Catbo Posted April 18, 2008 Author Share Posted April 18, 2008 Those have a beautiful finish..............Nice woodworking skills too with all the screws and no glue. Thank you. I did use glue to get a very good seal on the enclosure but I needed the screws to hold it all together until the glue dried [], because I didn't have anything to hold it together until it dried! [:^)], but screws+glue only makes for a stronger hold I would think! Quote Link to comment Share on other sites More sharing options...
Catbo Posted April 18, 2008 Author Share Posted April 18, 2008 Can you supply an address, phone, or e-mail address for the adapter supplier? I have the Goldwood horn, and was looking for that type of adapter. Any source information would be appreciated. Thank you!! I contacted the guy who purchased the adapters I have, it was purchased almost a year ago. It seems there was a China Company making speaker drivers, compression drivers, horns, and adapters that didn't make it and sold off all their inventory. So the adapter I have, I have not been able to locate anyone on the internet having it in stock, searched Google and can't find it, but it has no name on it, just "made in china". I talked to www.jamacspeakers.com and they said they don't see those lately but said they carry the 1" bolt to 2" bolt adapter for $14.00 and have the 1" bolt to 1-3/8" screw adapter for $7.00, he said the two adapters would be needed now to do the same, for the 1-3/8" screw driver to 2" bolt horn. Click on contact information for address and phone number. Sounds like they may be able to help. He said they have two of each in stock now. I also remember coming across a German website of a guy who makes wooden horns and he showed on his website how to make a wooden adapter to mount a compression driver to any plastic or wooden 1" or 2" throat horn just out of a 1 ?/?" thick and 2" to 3" square wood that he cuts into shape and makes the exit hole from a tool bit he uses on a drill. It was interesting because I've never seen anyone do that and he said that works well. I spent some time last night trying to find that website again and cannot find it nor does my memory recall the website name. He made it look easy to do. If I find that website again, I'll post it here, or maybe someone else knows the website? Quote Link to comment Share on other sites More sharing options...
GaryO75 Posted April 21, 2008 Share Posted April 21, 2008 I think I have found a one piece adapter that will do what needs to be done to join the Atlas driver to the Goldwood horn. Go to www.speakercity.com, then click on the P-Audio logo. In their listing of company sectors, go the the P-Audio Adapters, and scroll down to the PC50. It's a one piece unit that looks like it should do the job. I have a couple of them coming to me to experiment. I'll let you know how it goes; it is supposed to be 3.5" tall, so I'll have to see if I can make the three pieces fit into a CornScala II box.

dmonte Posted April 25, 2008 Share Posted April 25, 2008 In searching for an adapter I came across this compression driver that would be a direct connect. http://www.speakerrepair.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=genem&Product_Code=04-300 Seems like a very high quality unit, can anyone think of a drawback of using this instead? And for myself I don't know if a tweeter would at all be necessary with this driver, I doubt very much I could hear anything over 18,000 Hz at this point :-) Quote Link to comment Share on other sites More sharing options...

Catbo Posted April 27, 2008 Author Share Posted April 27, 2008 GaryO75 - wow, thanks for sharing that with us! I searched all over the internet looking for one and couldn't find it any where. I've had a few people asking me where to just get a 1-peice adapter to use with the Goldwood horn, now maybe this one will help them out. It should work as long as the horn + adapter + comp.driver = no more than 13 1/2 inches internally from front to back for the original cornwall size. You will also gain 1 inch or more (can't remember) if you front mount the horn like I did. Let us know how it works out for you and thanks again for sharing where to get an adapter for it!!

Catbo Posted April 27, 2008 Author Share Posted April 27, 2008 dmonte, I don't see why the P-Audio BMD-750 2"Throat Compression Driver wouldn't work, as long as you make the compensations needed to the crossovers you use for the proper output to it and the woofer. I have the Klipschorn's that go up to 17 kHz and other speakers that go to 20 to 23 kHz and I can't hear any difference, I hear everything in the Klipschorn's that the others higher kHz do so I guess my ears aren't sensitive enough to pickup higher than 17kHz?? Looks to me you could bypass the tweeter but I'm not one to know enough to say for sure on anything but you could always give it a try and see how you like the sound.

dmonte Posted April 27, 2008 Share Posted April 27, 2008 Yes the tough part will be finding a bass driver that blends well with that compression horn that is 108 db and 8 Ohm's .Orange County speaker recommended the following to match with the P-Audio BMD-750. http://www.speakerrepair.comEminence Kappa-Pro-15LF-2 - 600W RMS / 1200W Peak 38Hz-1.8kHz Quote Link to comment Share on other sites More sharing options...
dmonte Posted June 15, 2008 Share Posted June 15, 2008 catbo how about a follow-up review on your super C walls? if you were to build another pair would you make any changes at all ? Which set have you been listening to more, super C,s or your Khorn's? Quote Link to comment Share on other sites More sharing options...
Catbo Posted June 23, 2008 Author Share Posted June 23, 2008 Hi dmonte, I'm very pleased with the Super C walls. I've been amazed with the sound quality. It's a very clean, clear, and smooth sound. Piano keys and strings sound more realistic and the overall sound just sounds more rounded, fuller sounding, more real sounding, more relaxed sounding, and a little more detailed, probably has much to do with the tratrix horn with these differences? I haven't been listening to my Klipschorn's. I find myself listening to the Super C Walls more than any of my other speakers. If I were to build another, I wouldn't make any changes with how this has a very nice balance from top to bottom. I would be curious how a larger horn setup would sound like the jubilee but I can't imagine a larger sound than I'm already getting with the Super C Walls, but I know the jubilee would be larger sounding. I'm happy with the Super C Walls sound and feel content and set with it. How's your speaker project going? Quote Link to comment Share on other sites More sharing options...
