Well the new speakers have settled in nicely. Using the OEM drivers is always a bit risky even when they are basically copies of Peerless design. (According to the suppliers).
I have altered my opinion of the tweeters, its settle in much better than I would have thought. The 1 dB attenuation didnt seem like much but is precisely the required amount, the essyness has all but gone and mids are now well defined, especially for the vocals, both male & female. Base extension appears to be as good as the graphs were indicating. In fact base extension and level is so good that I have the Base level at either 0 or -2dB as the standard level.
Bass notes I didn't know existed in some tracks are easily heard and the roll off is excellent. I can hear the thrum of individual notes die out after they have been played.
Overall there isn't a lot I would change, possibly go for some better caps for improved tonality.
I'm now confident enough with this new design to put them on the market.
They are currently being used in my HT setup as fronts and are running in conjunction with the Aria Pettites which are a Paul Carmody inspired design based around his ClassixII
This is a very nice pairing between front and rears.
The sound of these is very similar to the B&W 684's but doesn't display that slightly reserved feeling I get from the B&W and my old Kefs.
Based on the outcome of these speakers, I'm now going to do a 3 way version using the same enclosure design as it has proved to be very neutral to resonances, and that of course was the intention.
