TB W5-1611SA vs. MA Alpair7
Hi guys,

I would appreciate if you could share your experience with these two drivers.
I've not heard any of them, just deciding which one to buy.Price is very similiar. The enclosure will be a sphere, amp not decided yet (probably some Japanese vintage - I'm in japan now, unbelievable shop with used gear :) old pioneer amps for under 100 :) )
Listening levels low to medium, music type classical, smooth jazz, ocassionaly all types from disco to metal, room 4,7mx4,8m, around 2,5m high, wooden floor, some rugs.

Any other info you need, just ask.

The TB is more sensitive, but I think the MA has got a far more honest FRplot. I have heard neither. One is metal cone one is polypropylene. I tend to like a phase plug better than a dustcap, but the MA drivers are supposedly cutting edge technology wise. Um, I guess this is no help at all, heh.:confused:

The other chinese manufacturers think Mark Fenlon is crazy to be as anal as he is on the level of consistency and precision he demands in his drivers.

I'm listening to the A12 (just in a temp OB, and only 100 hrs on them) and these are pretty special. The latest dustcap tech, the multi-forming cone technology, and the trick suspension all contribute to something, that, as one would expect, are a step up from his earlier drivers. A7 is built to the same level. New CHR and the CSS EL70 all have as much of this tech as possible for their price point.

W5-1611SA vs MA Alpair7 vs others
Thank you all for input.
Just to fill in the start thread:
I'm considering all these drivers
-CHR70 in 25 or 30cm sphere (8,2-14L) good price/performance ratio
-Alpair7 in 25 or 30cm sphere, very good reviews price ok
-W5-1611SA in same spheres, not much info, price is good
-168E Sigma in 30 or 40cm sphere (14-34L), I'd like to hear your opinions on this, high price/high performance ?????

When I decide on driver, next will be construction issues :D

Help me decide :) folks
If you think of any other driver,Im open to suggestions (please, up to 160Euros/pcs top)

EL70 and Alpair10 could be in the list as well? but maybe you could decide a size of driver, that should make choosing a little less difficult... larger full range have something special, but smaller have the benefit of better off-axis highs

barackuda 17th March 2010 04:37 PM

Hello Henkjan, well the size is open to suggestions, as I have at hand shapes in 25cm, 30cm and 40cm diameter.the volumes are 8.2L , 14.2L and 33.5L respectively. I'm not concerned about the size, more about the sonics. What might be a good compromise between size, off-axis response, bass extension (pair of woofers will be added later) and of course looks.

BIG in Japan :)

What do you think about the price for this 168E Sigma? its used, about 10 hours on them, very good shape, looks like new, amazing driver. The price is for one peace, around 100Euro....

And some other goodies :
