Hello,

I just logged myself in so first of all: Hi Everybody Wink

Few days ago I aquired a pair of very interesting 3way horn speakers which seem, as I imagine, to ba an ambitious DIY project from the past. These are basically the Altec Vott A7 replicas (made of 25mm plywood) loaded with 15" TAD TL-1601 8 ohm speakers, a completely new for me Onkyo HM-300MK2 horn tweeter/squawker/midrange/whatever, and last but not least the legendary german Corona plasma tweeters.
This system also contains a pair of active Sony SRP-F300 crossovers.
I know TAD but this Onkyo Horn is extremely rare and I only found some japanese websites which I completely didn´t undestand. I connected these drivers without any crossover and immediately was very suprised about the sound quality. They sound very very smooth. I had some experience with Altec horn which IIRC sounded more harsh and sharp. Not these Onkyos...they sound more like EV 1823 in Sentry 3. They also seem not to be extremely efficient like the others.
Anyone have some experience with HM300? maybe some fellow members from Japan could tell me something more about it? I´m not sure if I understood the translation correctly but it was told that the crossover point suppose to be at 300hz which I don´t really believe. I like them very much and I think these are keepers but I´d like to know more about them anyway...
I will try to connect the entire system within next few days as soon as I organise all amps (6 x mono) and xlr cables for both active crossovers.

Cheers

Pawel

edit: I just bumped into another japanese website and look what I´ve found: http://ameblo.jp/sp3/image-10019757868-10011792151.html
So 300Hz? really?
