Thank you for the correction. They are indeed sectoral.

Acceleration is SPL - the higher your acceleration, the louder you are.................Anyway, in a driver what limits how fast you can change your acceleration (rate of change of acceleration is the jerk force) is the inductance. That's what limits your transient response. Mass really has nothing to do with transient response. Only efficiency...................Efficiency is affected via mass changes, but transient response is not"

Given the choice between multi-cell and "One Hole" horns, I've made my choice.
so 15 would be better than 8?

Pano, please san I ask for your reasoning (in detail if pos.) why you feel/think that way and made that choice. I very much respect your opinion & knowledge

Then you should get the TD15m. It has light cone, high efficiecny, and Le better than any others @.2mH. That is 25% of most others you have looked at or talked about. It also has light cone.

holy cow 0.2mH? It'd kill you if you just thought about music, let alone play it!!

I think more cells = better because that's what I've heard. Not what someone told me, what I've really heard. I've heard the multis from 2 to 18 cells. More always seemed better to me. Bigger, more open, more real. That said, the 1005 and 1505 may be the practical limits for home use.

As for placement/aim of the multicellular horn - do you fire them straight forwards, down the room? Or toe the in so the centre is aimed at the listener?

Both work - it may be room dependent. Currently mine are pointed straight at me. That could change in a different room.

Thanks Pano. I've asked the ebay guy about the cell terminations and I'l let you know what he says. Here's a pic the maker sent me of an 18 cell version.

Wow he was quick!!

"Because of the widening of the of the entrance it keeps all the 15 appertures the same area never thought about it before. they could be tapered if you prefer that would give the outside 6 cell slightly more area"

I guess he means widening at the external cells. I think its because his cells start from a flat plane rather than radiating out, as if from a central point.

What thinks you?

Just thinking on the above, doesn't that mean the outside are a different length to the rest?
