InventiveAudio.com Posted July 19, 2002 Share Posted July 19, 2002 Hi, I fnally got my digital camera and have taken some pics of the different crossovers from each K-Horn that I recently obtained. I was hoping someone could identify them and give me some insight. I'm wondering if they crossover at the same frequencies and why one is so much larger then the other? http://www.nyonline.com/klipsch/crossover.htm K-Horn: 1965-K-B-WO Serial: 2D190 Alnico Magnets Crossover: Type 1RB K-Horn: Pre 1965-k-b-WO Serial:1704 Style: B Crossover: K-500-5000 All drivers updated to match the above K-Horn. Original crossover and Fiberglass horn. Quote Link to comment Share on other sites More sharing options...
JohnA Posted July 19, 2002 Share Posted July 19, 2002 You have a variation in the crossovers that I have never seen before. The 1RB is completely new to me. Have you drawn the circuit to see if they are at all similar? I once had Klipsch custom make me a "new" Type AA network, but the parts yours are made from are surely no longer available. Having one custom made to match is probably out. I've seen K-500-5000s on ebay. John Quote Link to comment Share on other sites More sharing options...
k2dx Posted July 19, 2002 Share Posted July 19, 2002 I haven't seen that 1RB before, but I don't have that much experience. I can see it has two inductors, one iron core and one air core. Can you trace out the circuit and scan it? The metal 'cans' are caps, there should be values marked on the sides, the voltage rating is unimportant in this application, but the capacitance is. It will be in units called 'microfarads' abbreviated 'uFd' or 'mfd'. The second one, the 500/5000 is the same as one I'm trying to identify as to vintage. This one I have was installed in a Brociner/Klipschorn, vintage probably early to mid 50's. It may have been an update and has w6 stamped on the nameplate. My other 500/5000 crossovers are different, having three air core inductors. They are definately '54s. I had posted an inquiry about the one with the two air core inductors and one iron core. There were no replys. You will find variations in both the physical layout of these networks, having been assembled by different workersand subcontractors.There are also variations in the capacitors, different values being connected in parallel to make up the same total capacitance. Nice pair of khorns, were they the ones in suburban Phila area on ePay? Good luck with them! Fred Quote Link to comment Share on other sites More sharing options...
InventiveAudio.com Posted July 19, 2002 Author Share Posted July 19, 2002 Fred-I bought the K-Horns in PA. About a 300 mile trip from NY. I'm a happy camper. I was wondering if the mystery crossover is similar to the 500-5000? Here is a macro of the crossover with labels. http://www.nyonline.com/cross.gif ------------------ Electronics: Two" TARGET=_blank>http://www.nyonline.com/klipsch Electronics: Two Sherbourn 5 channel, mono-block amplifiers. 200 watt bi-polar design. Very similar to the Bryston amp with more power and a much shorter warranty. Incredible reviews got me to buy this amp. I wanted mono-blocks for 5.1 listening and I can hear a huge difference over my old B&K AV5000II amp. The B&K was a great 2 channel amp but for 5 full range speakers it was not too good. I can hear sounds in the rears and fronts that I didn't hear before with the B&K. I really believe that 5 full range speakers require mono-blocks to perform correctly.Two Newcaste preamps. These preamps are dark horses. They are dead silent and transparent with incredible bass, gain, and speaker settings. I also have a 6 channel pass through and a CD analog pass through. One Pioneer Elite 47A DVD, SACD, DVD-A, MP3, player. I love the DACS on this player and am addicted to the new, high rez formats. One Pioneer 414 DVD player. Great picture with OK audio. One Denon DCD-1500 CD player. This was one of the first CD players to be produced. VHS: Who cares! Just got digital TV with on demand movies and programming. Most of the channels are in DD so I have really been using my 5.1 setup. Cables are Monster and AR and Dayton. I don't believe in spending big bucks on this. My setup is not ultra-high end but is on the cusp of it. You could spend thousands more but I doubt of you could get more then 10% better sound from the gear I have. I haven't heard tubes on my rigs yet so I better hold off on my last statement. Quote Link to comment Share on other sites More sharing options...
k2dx Posted July 20, 2002 Share Posted July 20, 2002 The 1RB appears to probably be a 6db/octave crossover, the difference being the 500/5000 having a steeper crossover for the tweeter (better lower frequency attenuation). Call Klipsch Monday... maybe they can tell you more. Quote Link to comment Share on other sites More sharing options...
Vavoline Posted July 20, 2002 Share Posted July 20, 2002 Trader, did I read in another post you got those big old horns into a Nissan Pathfinder? HOW??? Quote Link to comment Share on other sites More sharing options...
InventiveAudio.com Posted July 20, 2002 Author Share Posted July 20, 2002 K2 I called Klipsch and talked with their resident expert who misplaced the scematic and specs for my crossover. I was told that the crossover was designed to work with the wood/fiberglass horn I have and not to swap it our for a 500-5000. One of my K-Horns had its guts removed to match the newer 1965 model. It's interesting that each crossover is so much different. I wish I understodd the elements that are present and how it effects sound. For the record the K-Horns were hauled in a trailer. There's no way they are fitting in a Pathfinder. WIshfull thinking on my part for about 20 minutes. (: Quote Link to comment Share on other sites More sharing options...
Vavoline Posted July 21, 2002 Share Posted July 21, 2002 trader, thats sounds more like it. Hope you enjoy those khorns. I had an opportunity to score a pair locally, but it wasn't meant to be, I guess. Quote Link to comment Share on other sites More sharing options...
