[QUOTE="chipwelder, post: 1593, member: 54"] These were made for it... possibly mechanical excursion limiter... veddy cheap, the first order was existing X-O in ceiling mount speak - will use better cap and large gauge inductor on 6 inch polyprop ( which left to its own devices gets up to about 6kHz - with dubious fidelity), they are upgrade of old mini-fi speakers, besides x-o going to be up at 3-4, maybe even 5kHz... Am just damping baskets, sturdy box with port that'll be variable, probably not lower than 60 - 70 Hz... eartuned... saw about 3mm excursion one way without audible distortion... maybe if it has to do mid as well you'll hear distortion... but they seem to be the epitome of well behaved drivers... at cost of most everything else...
