Line Array Speaker

I am getting more and more interested in different speaker design .
Originally I want to try infinte baffle design (and make good use of my Diatone P-610MB).
But recently I found some interesting stuff about line array speaker when I surfing the net.
Since those small full range speaker from Tangband were quite cheap, I should give them a try.
Maybe they will sound good in TaShi house .

Update 20060502
Recently , there is a group buy rush for Tangband w4-1320. I did not join for some reason.
After I study some info from internet , I start to realize line array is not how it looks like , not as waht I've imagined at least.

Plate choke

These two iron stuff are 70H/30ma plate choke for driver stage.It did not improve the sound as I expected, somehow brought a narrower bandwidth impression . Maybe they're not good quality choke, need to figure out this later....
