What is its power handling like?

A disadvantage is that most amps don`t deliver enough current for the 13s rise time. A friend of mine tuned his power amps with large mica impulse capacitors in the power supply. Breathtaking performance.

One has to watch out not to mix things up. The rise-time has nothing to do with current delivery (or better: current consumption). Current consumed is a function of impedance and driving voltage.
Rise-time is also affected by impedance (namely inductance) but other factors as well.
The Manger is almost resistive only, with a very low 16uH series inductance which is an easy load for almost any amplifier.

If you don't use an amp with high bandwith (Manger recommends > 150 kHz) you don't have any disadvantages from the fast rise-time of the MSW but you don't get all of its advantages. Simple as that.

As far as disadvantages go, there are two that I can name: Somewhat higher distortion than other drivers and two "holes" in FR at 800 Hz and 1600 Hz.
But even though there are some things that others do better I wouldn't change to anything else at the moment.

Regards

Charles

Hi again,

yetserday I've heard third audition with swing+subsonice.
Mmmmh, something of not perfect in the integration sub-sat.
But the 200Hz ---> up is "magic"!! Really amazing.
I have suggested to my friend to ask the little zerobox bookshelf
to the distributor, but at the moment they do not have " in-house".
I' m very curios to listen it...

Cheers,
Inertial

Hi, Yeroenkv.
Yes, you are right.
But from the moment that one swing plus two subsonice(manger also)
costs about 8800 euro, my friend want to try the little zerobox bookshelf ( 3400 euro).
Again I am skeptical about the very low ( 90 Hz) x-over freq suggested from Manger : my ears hear something of not correct. Just my opinion
of course.

You can also do it the DIY way. Buy a pair of Mangers and Vifa woofers and use the filter & building plans from their site.

Oh, the speaker isn't for me, is for my friend!!
He is a bit "snob", and like "trade" , signature, etc.
But I have the opportunity to listen and comparate (to my DIY) the best loudspeakers he can test.
And this is very important, IMHO.

regards,
Inertial

Wanted to purchase two scan_speac 25w_8565_00 but it seems model have removed from production. Can there are best variants?

Hi max653,

The original woofer of the subsonice is a VIFA 10" ( custom I believe).

regards,
Inertial

Default fast rise time

Charles

> Rise-time is also affected by impedance (namely inductance) but other factors as well.

What are the main determinants of fast rise time, in order?

What amps (eg around 50 watts) would have a very fast rise time, the Aksa 55?

Thanks
