Pictures would also be useful. I'd definitely be interested, depending upon the details, if it appears to be a reliable manufacture. Low(is) Fs and High (ish) Qts and high efficiency, rare balance. I'd expect Vas on the order of 400L if these specs hold (and they're 8ohm). On the other hand, depending on the looks of things, it could be an issue of car audio specifications
johnmark said:I bought these about 4 years ago.
I tried the number sequence with a 290 instead of 299 and switched some others around and there were lots of speakers but I guess the number has been reassigned. It seems it was last used for a Pioneer 10" poly cone (I think)
more info I found the ad flyer so ..
