jason str Posted December 18, 2013 Share Posted December 18, 2013 Claude peaked my interest on the K-43 woofer use in the LaScala and i looked but cant seem to find any information here though i know i have seen it around. The new forum is playing tricks with some information it seems. Anybody have information on a SPL chart for this. Does the K-43 get rid or reduce the bass hump the LaScala has ? Also is there a direct replacement using a new Eminence driver or anyone have the K-43 theil parameters ? Quote Link to comment Share on other sites More sharing options...
djk Posted December 19, 2013 Share Posted December 19, 2013 (edited) Gray is K33, black is K43. K43 vented mod, no EQ. I use an EV Interface A EQ that adds 6dB of boost centered at 35hz. With the EQ they measure good down to 30hz or so in most rooms. Edited December 19, 2013 by djk Quote Link to comment Share on other sites More sharing options...
jason str Posted December 19, 2013 Author Share Posted December 19, 2013 Thank's djk, there does not seen to be much difference according to the graph though im sure to the ear it would make a bigger difference. More input would be appreciated if anybody has any. Quote Link to comment Share on other sites More sharing options...
ClaudeJ1 Posted December 19, 2013 Share Posted December 19, 2013 (edited) Thank's djk, there does not seen to be much difference according to the graph though im sure to the ear it would make a bigger difference. More input would be appreciated if anybody has any. What djk shows is a hornresp simulation, not a measurement. Real measurements are good too, but listening is believeing. What Roy Delgado said about the K-43 woofer is that it has a higher BL product which tips the response towards the mid range instead of the bass. I lived with LaScalas for decades as center as well as main channels. When I tried K-43's I was Amazed at the greater MIDRANGE detail I would hear....guitars, saxes, female vocals, etc. It does, however "thin out" the bass substantially, but if you build another THT, you won't miss it, I promise. IndyKlipschFan's home theater is all commercial split LaScalas with K-43's in the bottoms and it's one of the best I've ever heard (outside of my setup, of course, LOL). And NO, nothing tames the LaScala/FH-1 peak except a PEQ. Sorry. Edited December 19, 2013 by ClaudeJ1 Quote Link to comment Share on other sites More sharing options...

I would like to get an EQ to adjust some minor frequency peaks but worried about adding unwanted noise to my system. Quote Link to comment Share on other sites More sharing options...
djk Posted December 19, 2013 Share Posted December 19, 2013 "I was Amazed at the greater MIDRANGE detail I would hear...." The cone is a lot harder texture and doesn't damp out the detail like the heavier, softer K33 cone. The Qts is a lot lower too, suggesting the motor is too powerful (less bass). 1 Quote Link to comment Share on other sites More sharing options...
Frzninvt Posted December 20, 2013 Share Posted December 20, 2013 I want to try a K-43 in my center channel La Scala to improve its midrange performance. I have read though the one you want is the steel stamped frame version since the cast version will not fit without hacking up the inside of the doghouse. I think I will keep my eye out for one in good shape. Quote Link to comment Share on other sites More sharing options...
