Default good midrange

Hello there, I currently have 12m revelator midrange and I am look for a replacement. It must be better, same pricerange(or a bit more) as 12m, higher SPL and/or higher power.
I have an active system with
2x21W8555-01 with Aleph 5
12M4631g00 revelator with Aleph 3
D9505/990000 revelator with Aleph 3
active system, first pictures


Ok, any suggestions?

I would only replace a Revelator with another Revelator - I don't think there's anything better - subjectively maybe, given personal preferences, but not in terms of distortion measurements.

I agree, but the spl of the 12m is not that great and also the 40W.
Most of the time I play classical music on a live-concert level(very loud!) and I dont think the single 12m is enough (and I don not want to use 2 drivers parallel as the 12m is only 4 ohm)

40W should be power rating without a crossover. Your midrange's real power handling and excursion limit should depend on the HPF setting you're using now. I'm pretty sure that your bass drivers' excursion will reach its limit before your midrange's does with most of music materials you listen to.

Its your xo you need to address ... its a 89-90 db driver and should be sufficient
You may need higher xo points, at least 300hz ... what are your xo points and slopes
Well, I suppose with active its a 24db ... try 12db

You may also need to raise upper xo point ... fore some reason the revelators seem to sound a bit lazy with low xo point ... well, I only know the 15W, which can sound very distorted and quite awfull ... but its all in the crossover

There are plenty of excellent sounding pro drivers with 96+ db/w sensitivity out there.

Please point me to a distortion graph for this. I'd love to see it!

I am crossing at 350 and 3500 hz with 24dB LR.
I do like the sound of the 12m but it cannot be played as loud (breakup?) as I want and the tweet and woof can!
So must I build an new case with more 12m's and maybe an extra Aleph? I don't want to.... I want an alternative speaker with more power and same quality as 12m.
Magnetar; please name some?

The Audax PR170MO comes to mind -

Look Here

Very high sensitivity, low distortion and smooth to 3-4k. It can be crossed at 300 but 400 is better. Sounds best on an open baffle.

These are very good - I never had the Scan Speak - Still waiting on a distortion graph?
