I have looked at three of the Alpair drivers in a couple of enclosure concepts, including resonant enclosures (TL's) and even some OB concepts, and they look very promising. If the manufacturer's specs are accurate I think the drivers might generate really high perfromance designs at very reasonable prices. The one thing I do find confusing is the two different color cone options which seem to offer different performance trade-offs according to the manufacturer's website.

Hi Martin,
The coating processes used on the Alpair 5s alters the driver's performance. Cone rigidity changes when we use either our soft or hard treatments with the grey model's cone rigidity being higher than the gold version. This plus a few other tweaks causes the performance difference between these drivers.

The grey Alpair 5 is noted for its accurate clinical deleivery, making it popular in Japan while the gold verison sofer cone has a more mellow tone, usually appreciated more in Europe and the West.

For the other Alpair drivers, the coating processes used are similar regardless of the colour, and so driver performance remains the same. In these cases the colour choice is to give customers cosmetic choices.

We've done a lot of work over the past 3 years developing cones and caps with most effort going into profile design, tooling and sourcing multi-grade alloys from Japan and Taiwan.Combining all these elements has been challenging but satisfying and we hope to offer more drive choices in the future.

We are busy further up-dating our web site so will take another look on how we present the information.

Thanks,
Chris

and, have you tried anything else yet?

as a quick test I put them in a horn enclosure I had standing around (the one I had the TB W5-1611 in), and after some additional stuffing the sound was already very good, no notch, just pure full range pleasure....

Chris,

Could the Alpair 6 be made available in Grey AND circular flange if I order 3 pairs ?


Thanks,
Patrick

check with Blue Planet Acoustic www.oaudio.de they are the German representative

i'm looking forward for TL or MLTL designs for the alpairs, but anyone find the solid wood sounds better than mdf or plywood?

cheers

The Jordan is actually 9mm peak-to-peak, so 4.5mm xmax one-way.
