Default Seas MU10RB-SL or Scanspeak 10F/4424G?

Just wondering how these two mid range drivers compare to one another?

One is used in the LX521 speaker the other in the Nao Note II RS.
Both these drivers appear to be utilized in the same way, as mid range in a dipole configuration operating over the range 1-7kHz.

Price wise though they aren't similar as the Scanspeak is $100 and the Seas is $57.

Could these drivers be easily substituted with a full range driver like a Fostex FE103en or similar?

The Scanspeak just bc I listen to it daily and there's absolutely nothing wrong with it, very, very nice midrange!

It also has 5dB higher sensitivity than the Seas and a more linear response between 1 and 2 kHz.

Measures nicely too in third party measurements, very low distortion!

SS also more efficient than the Seas.

There's plenty of measurement of both (e.g. Zaph, MarkK). Clearly the SS is the winner.

I have heard it (not the Seas) on NaO note and they are very nice indeed.

The SS looks extremely good to 15khz off axis, I'm very surprised these aren't commonly used as wide band tweeters. I'm taking that route with my next speaker project, as I cant see a down side?

I may have to invest in a pair then as they are readily available in the UK for around 62 each where as the Seas are only available in the LX521 bundle. I worked out that to import the MU10 from Madisound, it would cost 5 more per speaker.

I see my self very close to building the Nao Note II RS!
I managed to get another pair of the Peerless XLS drivers for a steal as well!

I suppose it is a question for JohnK but would his build plans be suitable for sending to a CNC shop to make up the pannels?

Because an actual tweeter sounds much better.

I am also tempted to build the Note II (nearly have a clone already). Struggled to find a UK source for the tweeters but found them for 50 eventually - special order only.

Is this first hand experience wuth the SS? All the data suggests otherwise. Then there's the fullrange crowd, but they usually use drivers with poor measurements.

Because they don't actually work like that. That darn thing called physics again. But they are legitimate 5K midranges, which are few and far between. Go ahead and try it, but leave room to add a tweeter later as you will want it.
