It's a 4" voice coil, aluminium alloy dome with mylar suspension. Looks good on paper but I don't know if it is good. The retail is $210, usually goes on Ebay around $160. So you actually set on your following midrange setup: S3 as a lower mid (as you call it fundamental) and S2 as a higher mid, crossed to RAAL. Right?
