Sold!

Selling a pair of Fastlane Fastrac horns designed for La Scala’s that I’m not using. They have been mounted, but are in great shape. Asking $550, plus shipping Thanks for your interest!

Selling the following Crites items that I’m no longer using. They are both used, been mounted, but in very good condition. Pair CT110 tweeters with B&C DE110 drivers, asking $180 Pair A-55G midrange drivers, asking $300 Thanks for your interest.

Thanks, no worries.

I only went up to 0.75” because my K-55-M were at 0.75”. It was an early mod. I’m now using Dave’s Fastrac horns with Crites A-55-G drivers. These have the 1” throat. I’m also using Crites CT-110 tweeters. Stock AL3 crossover with a few mods. Enclosure was originally painted black, later brush painted by original owner. I braced and cherry veneered it, finished with espresso satin.

Upgraded my 1994 La Scala's years ago, and finally decided to part with the original components that have been collecting dust. Pair K401 squawkers, slightly bored out from 0.67" to 0.75" to better match K-55-M driver - Asking $300 Pair K-55-M drivers - asking $175 Pair K-77-M tweeters with new Critics diaphragms - asking $150 I still have the original K-77-M diaphragms, one is still functional. Thanks for your interest.

The Eliptrac's are SOLD! Thanks for everyone's interest.

Yes, they were used with K33E woofers in my La Scala's and I crossed these over at approximately 400 Hz. I used the woofer portion of the AL-3 crossover and a slightly modified version of the AL-3 squawker portion. The AL-3 squawker portion is not a true bandpass and is designed to let the K55M roll off naturally, therefore it allows the HF144 to extend to it's 18K limit. The stock tweeter was also disconnected from the crossover.

Comparing the K55M/K401 combo to the K55M/Eliptrac combo, the Eliptrac is more open, smoother and forward sounding. Vocals are more compressed through the K401 and there is an ease of presentation with the Eliptrac. Everything just sounds more natural. I noticed and measured about a 1 db. increase in output with the Eliptrac, possibly because of the shorter horn length. The Faital HF144/Eliptrac combo is even smoother and fuller sounding. I used it as a 2-way without the Klipsch tweeter. I liked the sound of the HF144/Eliptrac combo the best, but didn't like the look of the horn boxes I made sitting on my La Scala's. I considered cutting the Eliptrac 400's into the motor board, but didn't want to molest the La Scala's that much. I like the stock look of the speaker, so I switched to the K55M/Fastrac combo and it was a slight compromise in sound, but still better than the K401. Presently my 1994 Lascala's have the stock K33E woofer, K55M/Fastrac combo, Crites CT110 tweeter and slightly modified AL-3 crossover. Mostly stock with some enhancements.

Still looking? If so, I have a pair that might interest you.

Adding the port tubes was my idea. I noticed that the bass was a little boomy around 80hz to 100hz so I modeled it using bass box pro and it did have a slight bump in response. I then modeled it with 4" port tubes and everything got better. I also rebuilt the crossover myself and got the caps and mounting board from Bob. I picked up the coils and resistors from Madisound. It was a little work dismantling the existing crossover, but worth it. Exerything got a little cleaner and more realistic sounding.

I obtained the T/S parameters for the K-48 driver from the Klipsch Tech Help Center. Then I modeled it using Bass Box Pro and determined that by adding ports I could get better bass response. With the stock bass loading there is a 3db peak centered around 80 hz and the F6 is around 45hz. This woofer really needs a larger box. By adding the ports I was able to almost eliminate the peak and was able to extend the F6 to approximately 37hz on paper. The ports are 4" in diameter and 5.5" long.
