Proac 2.5 Response tweeter upgrade with Ribbon Tweeter?


Greetings,
Has anyone tried replacing the tweeter (mine is Scanspeak 2010 851300) on the Proac 2.5 Response (mine is a clone) with a ribbon tweeter? Would it match or is this just a silly idea?
Thx for any comments or advice,

For many years I drove my 2.5's very successfully with a Cary SET 300B amp putting out about 13w max.  This combination was recommended by Arnie, the guy who founded Audiogon years ago.  It was rumored that Denis Had used Proacs when voicing his amps.

@mozartbrain If you read a lot of review of the 48R carefully, you'll see that they say that the ribbon is well integrated, better than most, but that if you system is already fairly revealing, they may give too much of a good thing.  I've tried in vain to find feedback on the D48, with the dome tweeter.

Thank you all for your comments.
On Thursday I auditioned the Proac D48r’s.

I brought along some vinyls - MJ BAD ; Messiah; Nat K.Cole etc.

1. Whilst we warmed up my Diva 25w/ch amp we listened to some CD’s (Eva Cassidy). We found the sound quite engaging: smooth, rich LF, nice mids and very smooth HF. However, we still found the overly ’warm’.

2. With the Diva connected on the 4Ohm taps and to the SS Pre - Phono - TT we listened to Nat K.Cole. Oh dear - sounded screechy and thin. We listened to some MJ and after a minute swapped the speaker wires to the 8 Ohm taps. This was much better. However, not the control of the bass and overall lost some integrity and coherence in there sound. We listened to some more vinyl with the same conclusion.

3. We swapped out my Diva for the shop’s SS Amplifier (100 w per channel) and everything was better. Control through all frequencies, smooth and engaging. The only thing we didn’t like was the slightly over ’warmth’ that is maybe a signature of these speakers.

So our conclusions:

1. My 25w/ch Diva is not capable of presenting the best that these speakers are capable of.

2. If I want a speaker of this ’ilk’ (2 woofers + Tweeter and crossovers) that needs serious drive power then I would need to purchase a new amplifier. However, I would rather investigate other speaker options so that I do not need to change my amplifier.

Kind regards,

Today we auditioned the Tannoy Turnberry GF. Wow! My amp had no problem driving these speakers. Whilst the specs say that the bass only goes to 40Kz it was a much more musical and real. The sound stage is huge and 3D (compared to my Proac 2.5 and the D48r's) Clean sound and transparent too.

My wife liked them but was concerned I might be playing them at the same volume as we tested today. I said, "not quite - just seeing what they can do through my amp" I actually took my SUT, Phono, Pre and Power amp. All great except for a hum which I think was just the set up in the shop environment. Would speakers cause a hum? The hum increased with the volume control. This doesn't happen at home.
The shop use their turntable, tonearm and cart. They produced a very high Rez and resolving sound. I think my Garrard and ebony tonearm would mitigate the slight brightness that we heard and suspect was their t/table, arm/cart combination.
Thank you, 

Glad you like the Tannoy speakers. I am sure they are a much better match for your amplifiers.

If you don't have a huge 3d soundstage with the D48r something else is wrong


(((If you don't have a huge 3d soundstage with the D48r something else is wrong))Yes in total agreement. They play music without ringing artifacts.To some folks, ringing offers a short term wow factor.
