Hi jzagaja

did you ever get a chance to listen and measure the B&C DCM50 with one of your horns?
i would be especially interested how it sounds and measures w/ the Iwata 300 ?

Not yet. We use BMS and Radian/Truextent.

K-horn is similar to Klangfilm KL51, spherical horn, to be used instead of JMLC-400, slightly wider dispersion (5-10deg). Price -> diysoundgroup.com

Default K Horn vs. Iwata

Thanks for the comparison graph.
you say : to be used instead of JMLC-400 .
jmlc-400 has a recommended xover point of 600hz , KL51 has min rec. freq. of 400hz .
i thought i can take the KL51 down to 400/500hz according to autotech page .
have you had a chance to listen to KL51 ?
any comparison to iwata 300 re sound ?

Instead I meant mouth size, it's longer. I don't have a space (having Mummy and Universe) for test loudspeaker and horn swap. Autotech is building such for private use. They focused on listening test regarding JMLC-200T with Radian 950PB/Truextent and JBL 4560 bass bins (a friend installation).

I got JMLC 350 trough Erich’s diysoundgroup. They sound wonderfully with GPA 288, much much better than the Stereo Lab Tractrix 400 horns.

I have a question: there is a kind of tape on the outer edge of the horn. Is this tape embedded in the gel coat or it is just a protection for transportation purpose? I haven’t dared to try to take it of. Any owner of the Autotech horns had the same?

This is topcoat masking layer needed when you join two parts in this case horn and its rollback. Can be sanded when painted.
