By the way, I am looking for punchy, tight sound.
for exemple I only use pro amps (Crown), I don't like tube sound.
Maybe this can help.
I read on french forums that the BMS tends to be smooth, less impact that the Beyma.

For a tight punchy sound you should be looking at a more traditional cone-based co-axial. One with a lot of Bl.

Possibly the best of these is from McCauley.

Their 6224cx closed back 10" driver and their 6520 compression driver. Not cheap.. but I don't think you'd get a much more punchy sound from anything else.

Yeah Mc Cauley is a brand I have been interested into.

Even if it is a bit more expensive, I have to check if they are available in Europe.

Their website is down.

Maybe there is some good stuff from Precision Device.

Punchy, whilst not a technical description, usually represents a characteristic of the lower midrange. No 2" driver works well down there irrespective of the flare it's placed on. Try a 2220 JBL on it's own, x-ing to the BMS on an oblate speroid at 800Hz or so.

I also have a number of prosound amps and I can think of nothing worse sounding on a hi eff driver at close range than the low level distortions of these amps. But if you like it..... I'm just glad I don't have to listen to it.

Hi,

I already own JBL 2226H, I am not going to change them so soon and I like them a lot. Works really well on a pro Crown K2 amp

But I dont want to have a xover at 800 hz, first because it is in the middle of a lot of things, second because I don't think 15" speakers are as good as a compression at 800hz.
The highest will be 400hz. This is why I need a 2" compression driver.

Greg.

I've tried a LOT, and I've yet to find one that works that low on any practical flare.

With a 250hz JMLC profile, this makes a squared horn, about 60x60x60.
I know some french people owning a Beyma CP850ND and they tell that it can realy play low for home use.

I would like to see the THD (incl spectra) esp in the bottom octave before I comment upon what others "hear".

I think it depends a lot on the power you send.
For home use you can get more than 100db without a lot of power.
Don't forget that audio is always compromises.

You're still going to be asking a lot of excursion from it that low.
All engineering is about balance of compromise, but I think you're heading in the wrong direction, based upon my experience. However, don't let my opinion stop or dissuade you. You may love the result.
