Guest David H Posted November 13, 2013 Share Posted November 13, 2013 would these work well with AA crossovers in a Belle These are a direct replacement. Quote Link to comment Share on other sites More sharing options...
Guest David H Posted November 13, 2013 Share Posted November 13, 2013 Dave. This looks wonderful. I may have missed this but is this tweeter/horn a drop-in for the original K77 behind the baffle mount....such as in a la scala? Thanks JC, and Yes it is designed as a drop in replacement. Great to see you around again. Dave Quote Link to comment Share on other sites More sharing options...
SonicSeeker Posted November 13, 2013 Share Posted November 13, 2013 I am waiting on some AA'S with jensen PIO's from Dean, wanted to make sure these would be o.k. Also in the future if I wanted to go with your mid horn would this work also? Quote Link to comment Share on other sites More sharing options...
Deang Posted November 13, 2013 Author Share Posted November 13, 2013 I could have sworn you said you weren't going to change out the horn. No matter. If you do the Fastrac, you'll be fine. If you go to anything bigger than that you'll have a problem (too much gain). Quote Link to comment Share on other sites More sharing options...

After reading about them, they kind of got my interested. Thanks Dean Quote Link to comment Share on other sites More sharing options...
coolhandjjl Posted November 15, 2013 Share Posted November 15, 2013 The best thing I did to improve my sound was move the mid/tweet x-over up to 6k. Apparently the original K-Horns were at 6k. I read an article a couple days back a member had linked about keeping that 400~6k range handled by one driver. Very enlightening. Lots of superior tweeter & horn combos available all with their respective unique polar patterns, but crossing at 6kHz seemed to be the more important factor, polars be damned. (unless you have a HF horn that really collapses drastically between 3500Hz and 6kHz.) Quote Link to comment Share on other sites More sharing options...
Deang Posted November 15, 2013 Author Share Posted November 15, 2013 The 6kHz crossover point does three things: 1) moves the crossover point out of the most sensitive part of your hearing 2) gives you almost four full octaves out of the midhorn, and 3) reduces excursion of the tweeter's diaphragm which results in lower distortion.

bliss53 Posted November 21, 2013 Share Posted November 21, 2013 There is a DE120TN titanium driver available. Any opinions on Titanium Vs. Mylar? Quote Link to comment Share on other sites More sharing options...
Deang Posted November 21, 2013 Author Share Posted November 21, 2013 Yes. Quote Link to comment Share on other sites More sharing options...
Guest David H Posted November 21, 2013 Share Posted November 21, 2013 Yes. I have to say Dean, that was a bit vague. My preference is not to use Titanium. To my ears Mylar is a better choice. Dave Quote Link to comment Share on other sites More sharing options...
NBPK402 Posted December 18, 2013 Share Posted December 18, 2013 Would these be a big improvement over the stock tweets in a La Scala? I am thinking of replacing the tweets first, then maybe go to a Fastrac horn, and then crossovers. These are used 90% for movies but I think I would like to start listening to 2 channel music again too. Quote Link to comment Share on other sites More sharing options...
Guest David H Posted December 18, 2013 Share Posted December 18, 2013 If your Lascala's have the square magnet K-77 these will be subtle improvement. Replacing the mid horn would be the best place to start. IMO. Dave 1 Quote Link to comment Share on other sites More sharing options...
NBPK402 Posted December 18, 2013 Share Posted December 18, 2013 Is it possible to order just 3 Fastrac mids instead of 2 pairs? Quote Link to comment Share on other sites More sharing options...

tigerwoodKhorns Posted December 18, 2013 Share Posted December 18, 2013 The 6kHz crossover point does three things: 1) moves the crossover point out of the most sensitive part of your hearing 2) gives you almost four full octaves out of the midhorn, and 3) reduces excursion of the tweeter's diaphragm which results in lower distortion. So is it better to go with 6K for these factors, or move down to 4500 hz as many have done to relieve the K55 a little? How do the tradeoffs work? I have La Scalas that will use JBL 2470's and K Horns that will use the K55. Aftermarket tweeters on both. Quote Link to comment Share on other sites More sharing options...
ClaudeJ1 Posted December 18, 2013 Share Posted December 18, 2013 That said, I've measured B&C units, they're decent. Excellent, that's good news. I have had good results with B&C drivers as well. Dave Me too. I'm using a DE-250, mylar diaphragm on the QSC "mini me" horn that looks like a small K-402..........see avatar. Since I don't have to retrofit a Klipsch cabinet, size is not a factor here. B&C makes good stuff. Quote Link to comment Share on other sites More sharing options...
ClaudeJ1 Posted December 18, 2013 Share Posted December 18, 2013 Here it is: http://community.klipsch.com/index.php?/topic/30801-beyma-cp25-questions/page-1 Okay, I love the new forum. It took me less than a minute to find the post I was looking for. "A tweeter with 4-22kHz bandwidth will sound "better" than a tweeter with a bandwidth of 4-15kHz even if you can only hear to 15kHz. Bandwidth defines transient behavior, the broader the bandwidth, the better the transients. In other words, the 4-22kHz tweeter will be a better tweeter in the range you have audibiltiy. Repsonse linearity, as a function of input power (i.e. 1, 3, 5, 10 20W, etc) is also of importance. Lots of tweeters look very good at 1W input but not so at 3W, 5W, etc." I posted a quote from PWK saying the same thing about the GAUSS coffee can sized driver on the original 2-way MCM back in 1976. If it does 19Khz. it will be better at 10 Khz. or something to that effect. Quote Link to comment Share on other sites More sharing options...
babadono Posted December 30, 2013 Share Posted December 30, 2013 So....... Who got a set of these from ALK? Impressions? Quote Link to comment Share on other sites More sharing options...
Deang Posted December 31, 2013 Author Share Posted December 31, 2013 The tweeters just came in, I don't think anyone had ordered a pair yet. Quote Link to comment Share on other sites More sharing options...
Guest David H Posted December 31, 2013 Share Posted December 31, 2013 The tweeters just came in, I don't think anyone had ordered a pair yet. I believe only 2 or 3 pairs of these are currently in use due to lack of drivers. The DE-120 is out of stock everywhere. I am always on the lookout for a suitable driver.
