jwc Posted December 26, 2005 Share Posted December 26, 2005 Has anyone tried out the Eminence tweeters Such as the models listed above. They are rated at 104dB. I was curious about this one in particular: http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=290-536 I would think it would integrate with the networks fiddled with here. Just wonder about the sound. jc Quote Link to comment Share on other sites More sharing options...
Duke Spinner Posted December 26, 2005 Share Posted December 26, 2005 I think BEC is working on something using those Quote Link to comment Share on other sites More sharing options...
BEC Posted December 26, 2005 Share Posted December 26, 2005 jc, You had a pair of them. Bob Quote Link to comment Share on other sites More sharing options...
jwc Posted December 26, 2005 Author Share Posted December 26, 2005 Well I assumed they were a similar driver. Though maybe Eminence did some "special driver" for you like the new woofers you have. AS far as the Horn goes on that line of tweeter, I guess the APT-200 would have a good dispersion although bet it would sound different than your K77 like horn.

Daddy Dee Posted December 27, 2005 Share Posted December 27, 2005 I think they sound very good. In comparison with the K77, these tweeters have a startlingly better natural sound to drumstick strikes on cymbals and such. I have not heard them mounted to the horn you have in the PE link.

Deang Posted December 27, 2005 Share Posted December 27, 2005 I'm more interested in how they sound compared to other popular replacement units, particularly the Beyma which I find to be a substantial improvement over the K-77. With my highly compressed Rock recordings the improvement is marginal -- but with good recordings and DVD movies it's very impressive. I believe Bob is using the APT-50. I think his project will make the K-77 obsolete. When the modified unit becomes available -- anyone who opts for diaphragm replacement over tweeter replacement should have their head examined. I would also like to see Klipsch take a hard look at the unit -- I think it's time to put the K-77 to rest. Quote Link to comment Share on other sites More sharing options...
Duke Spinner Posted December 27, 2005 Share Posted December 27, 2005 put me down for the First pair, BEC I Detest the K-77 Quote Link to comment Share on other sites More sharing options...
jwc Posted December 27, 2005 Author Share Posted December 27, 2005 Well I guess I didn't realize so many people new of the details of Bob's new tweeter. Yes, Bob let me borrow a pair. It is definately a drop in replacemant for the K77. Quote Link to comment Share on other sites More sharing options...
BEC Posted December 27, 2005 Share Posted December 27, 2005 As far as I know, the mold to build the new horn is being manufactured now. Hopefully, I can provide good numbers of the new tweeter with the new horn in January. Price will be $150.00 per pair plus shipping.

jwc Posted December 27, 2005 Author Share Posted December 27, 2005 I meant to concur with what the others said above. If your tweeters are $150 for a pair, there is no reason a DIY guy or someone wanting replacement will need a K77. Quote Link to comment Share on other sites More sharing options...
tofu Posted December 27, 2005 Share Posted December 27, 2005 $150 per pair? wow.. i thought they were $150 each! Quote Link to comment Share on other sites More sharing options...
Deang Posted December 27, 2005 Share Posted December 27, 2005 That's what I told him he should charge for them. You wouldn't believe how much money he invested into that mold. Quote Link to comment Share on other sites More sharing options...
Daddy Dee Posted December 28, 2005 Share Posted December 28, 2005 Yeh, that mold project is pricey indeed. I've thought if I was doing the project, I'd be sorely tempted to go the cheap Chinese route. But Bob's tweeters are made in the USA all the way. Note to TomB, he is a non-union shop, though. :-) Dean, have you had a chance to compare these to the Beyma? I thought they compared quite favorably and even did better on natural sounding cymbals and such. Quote Link to comment Share on other sites More sharing options...
lar418 Posted December 28, 2005 Share Posted December 28, 2005 I was also lucky enough to test a sample of these gems and they sound extremely musical. I was able to lower the upper crossover point on my Industrial La Scalas to 4500 hz. This helped reduce the rise in response in the 6000 hz range and eleminated any ring the squawker may have had. IMO:The combination of Bob tweeter and the lower crossover point sounds more natural. Quote Link to comment Share on other sites More sharing options...

What kind of crossover and what kind of mods did you do to accomplish that? Quote Link to comment Share on other sites More sharing options...
lar418 Posted December 28, 2005 Share Posted December 28, 2005 The crossover is basically a DHA2 with a few modifications. I like the approach of using a true bandpass section on the squawker. I padded down the squawker similar to the ALK design by connecting it to taps 2 and 5. I used Goertz coils from Madisound and GE Oil Caps from Bob Crites. My marked up schematic is attached and the second post has a picture of the finished crossover. DHA2-004.pdf Quote Link to comment Share on other sites More sharing options...

BEC Posted December 28, 2005 Share Posted December 28, 2005 Here is a pretty simple mod to a type A crossover that I think might work very good with the new tweeter. I haven't built one of these yet, but I think bringing in the new tweeter a bit earlier and rolling the squawker off gently might sound very good. The new tweeter can take the power at the lower frequency, so no need to try to protect it. Bob Crites Quote Link to comment Share on other sites More sharing options...
Daddy Dee Posted December 28, 2005 Share Posted December 28, 2005 Lar418 and Bob, Thanks for the description here. BTW, what is DHAXover? Quote Link to comment Share on other sites More sharing options...
lar418 Posted December 29, 2005 Share Posted December 29, 2005 Daddy Dee, The DHA2 was designed by John Albrights brother. You can find John on the forum. The DHA2 is a constant impedance crossover similar to the ALK crossover, but with first order slopes. There are a few highly regarded designs on the forum, Klipsch original designs, ALK's and the DHA2. I've seen a few posts that compare these and the Klipsch Type A, AA and DHA2 are said to sound better at lower volumes, while the ALK's are said to sound better at higher volumes. I've only heard the Type A, AA and DHA2, but never the ALK's. Quote Link to comment Share on other sites More sharing options...
