There's no performance difference between the cones colours on this driver. It's only the Alpair 5 that has a performance between grey and gold.

Frame is made from ABS and acrylic tri-mix. It's a single piece injection unit so no joins, making it strong and also helps to damp resonance. Take a look at the pic and you'll se the rib box sections behind the faceplate. Tap the frame, it sounds like natural wood, very neutral.

These drivers also come with pva gaskets (seals) for easy mounting to the cabinet.

Sure, desktop, that sort of thing. I've also been asked if the CHR will be good as a mid range unit. Yes, with the right cross, its an ideal size for the job also.

Hi Patrick,
Yes, the cone's 10mm bigger in diameter, using a single aviation grade alloy sourced from Japan. This alloy can take more power that the hybrid mixed alloys used the Alpair series. Box software suggests larger volumes on BR. Bob Reimer uses Bass Box 6, that also came up with volumes around 7 litres up.

If you're looking for absolute sweetness of delivery, pure musicality then go for the Alpair 6. Henkjan has commented on this aspect of the A6's performance on this forum.

I think you'll find the CHR gives a very good account of itself against other full rangers of a similar price. The cone set it apart from most other drivers in class. Detail in the mid range is very nice, bass and highs are there to be used.

Hope this helps

Mark.

That means price no issue -> Alpair 6 ?
(I know I shouldn't ask such questions that provokes not-always-neutral answers.)

$65/pair means for complete 5.1 setup that just cost about $160

not bad, if they can perform at least 70% of the JX92S

Hi Patrick,
Yep so a pair of CHR's are half the price of a pair of Alpair 6.

Ummmmph, this is where we' re into subjective and judgement. Henkjan said it well, the A6 was the best small driver he's listened to but it's also the most expensive
He said "no free lunch"
But the CHR 70 I think will be very pleasant for most people's ears.

Hi Henry,
Its an idea to think in terms of 70% of the Jordan 92 (or Alpair 10) . Maybe the way to think of it is a sort of mini version with less bass.

Take a look at Jim Griffin's comments on the Alpair 10. He makes a comparison between the 92 and the Alpair 10:

Mark Audio Alpair 10 MLTL Design

"Well how does the Alpair 10 compare to the Jordan JX92S you may ask? The Alpair 10 tends to need a little larger enclosure volumes than the Jordan driver which I saw in simulations in sealed, bass reflex, and MLTL models. The larger Xmax of the A10 yields a little lower bass and higher overall SPL versus the JX92S. Furthermore, the larger frame of the A10 assures that you will need some baffle redesign because the two drivers have different foot prints. They apparently need less baffle step compensation. Bottom line is that given their relatively pricing, I would say that the A10 is an excellent value compared to the JX92S. The Alpair’s sound is comparable enough to the Jordan so that most users will be able to achieve that single driver magic at a lower cost."

Thx
Mark

It's a 4" full range, how can you possibly want deeper than that. If anything I think it's too low. I'd rather have had it more efficient and that's the trade-off you have to make unless you want to construct some sort of quantum mechanical driver that breaks the constraints on regular physics.
