Best floorstanding plan for Alpair 10.2 ?
I'm just thinking in terms of the simulated response... most would go for a sealed box with Q = 0.707 = butterworth = max flat or 9.2 litres. There is nothing to stop you from extending the sides down and filling the void with sand -- making it more difficult to knock over.

I was thinking a high output impedance amplifier might be in the mix somewhere, in which case the extra would be useful. Agreed though, with a high DF, smaller would be better once suitably stuffed.

You can always put a false bottom in the cab and ballast below.

Just curious, does anybody has experience with it on backfiring BLH?

If you're partnering with subs, a back horn isn't likely to be necessary, unless you happen to like the power-response produced by the larger radiating area within it's operating BW.

Just want to know their effect. If they really shines, why not. Subs is always a backup.

Stick to the Pencil 10.2 after considering different setups, since I have no idea how MA drivers sounded. Pencil 10.2 should be a good reference. Thanks to all the nice guy here.

Hello! What about these:http://http://www.diyaudio.com/forums/markaudio/192034-jim-griffin-a10-2-mltl-variation.html
Mark Audio Alpair 10 MLTL Design
How do they compare with the Pensil 10.2 and Bob's M10-A10?
Thanks,

As they said, M10-A10 has little edge, but not big difference.

which "who" exactly?


simulations are one thing, but has anyone actually listened to all the cited designs in the same room / system to formulate a real-world impression of their relative strengths ?

Having heard 2 different Pensils ( 7 and 12.P), and the 10.2 in several designs, of all these named, I'd be inclined towards Bob's, even if only for aesthetic reasons. But to extract even more from this driver, I'd probably wanna try the Woden Silbury. .
