Choice Horns 1.4" neutral sound

[Pano]

A well designed and built long horn does not honk. At least not with a decent crossover.
On the flip side, beware horns that are too short, as they can have beaming and horn "Blat" or the sound of the CD breaking up at medium volumes.

You need to find a JBL parts/service center in your part of the world.

Price will be more than *2 and waiting a few months .

Mleod,
What's your room (and speakers pacement) like?

the length of the horn is going to be determined by how low you want it to play with 1/4 wavelength being the most common compromise. for K-Tubes I set the tube at 1/4 Fs and find longer tubes do not sound as good.

I use an 18sound XT1464 with a Faital Pro HF144. I like it.

Much preferred over the two other waveguides I tried, Pyle PH916 and FaitalPro LTH142

Limmer horns are getting very positive comments in german fora but again no personal experience.

Test Bench: Eighteen Sound ND3ST 1.4” Compression Driver in XT1464

This is not the first time that I have read that about the LTH 142 but I do still not know why. Someone mentioned that the dispersion of the XT 1464 would be better at its upper end but no other "complaints" about the LTH 142.
If it is just a frequency response thing then it could probably be EQed out. I am interestd in the LTH 142 because it is smaller and it looks prettier than the XT 1464 ( Unison Research uses it in the production version of their MAX 2 Speaker). I will probably build a 12" version of my MTM and I will cross over a little higher than I do with the 15" version and that's where ther LTH 142 might come in handy.

from a F point upwards, we know K-tubes will work. WVL was enthusiastic but the public doesn't seem to accept the looks of the things so there's a marketing problem.

(WVL's field coil driver looks stunning)

here's my 115BK some years ago with a custom 1.875" ID x 9" long tube - derived from an X15 Karlson tube of the 1960's. Karlson had a strange beveled 1"Id transition piece in an 1.875" x 7.25" K-tube - subjectively, it sounded fine, but could measure rough (probably from the transition "jump") - another specimen of X15 appeared to have a 1.2" ID tube x 7.25" long - that probably measured pretty smooth.

Hello people!
Thank you for the many interventions. Following the many suggestions I ordered a pair of 18sound XT1464 horns, when I got this and did some test I'll let you know. Thank you all. Greetings.
