Hi

I've had some MT122's I built some years ago now. I'm just building some more but has the spec'd horn changed? I thought I got the correct horn (at the time) as I can't see the ones I currently have available anywhere I assume that they are no longer available?

Can someone help me identify what horns are in the pic below?

I was hoping to have all four horns matching but this may not be possible. If not how do people find the 2723 horns? How long has this been the spec'd horn?

Thanks

Phil

It looks like Beyma td460.

it's almost impossible to find P-Audio horns and drivers (in EU) which are included in the orginal spec.

From this reason I choosed Beyma CP750 + Beyma TD460, but if you have better budget I recomend to go with BMS 4592ND

I'm sure its a P audio horn of one sort or another, I should be able to remember as I did buy them new but I can't remember, I'll have a closer look at it tonight. There are tons of pictures of mt122's with the same horn knocking about, its round throat as opposed to the slot type throats is a distinguishing factor. Blue arran have lots of P.Audio horn inc the one on the current plan but I wonder if the one spec'd on the plan has changed. Its probably 6 years since I built these cabs. The current one spec'd (2723) has a much smaller mouth. The 2723 looks like it probably has a better dispersion pattern that the ones I currently have esp for arraying 4.

Thanks
