A question along the lines of the 0.69 wonder.....

Consider the following driver. What looks to be a laptop computer or something....



Although by themselves they probably don't put out much, how do you think 30 or so per side would do?

Their only rated at 0.4W each, but with 30 of them per side, they would hardly need any power for normal llistening (80-90dB). I don't even know what to call this style of driver...i tried searching small flat speaker, small thin speaker, but just got normal stuff (like "this speaker has small enclosure that is also thin", or NXT speakers). I didn't know if these are called specific types of drivers.

I can buy 60 or so of these for less than $15....do you think it would be interesting? I think a line of 1.5" holes on a baffle would work....possibly high pass all the bass (below 100Hz) out to keep the excursion low.

What's the resonance frequency? That might choice you a bit as regards the LF crossover point.

Do you have a link to these? Also, on another point, i was playing with 2 8 ohm 2w 2" speakers yesterday, highpassed at 120hz, and they were taking all of 30-40rms and stayed fine. Those will handle alot more than .4w with a higher crossover, just like the Tangband w3-871 will take 100 watts when HP 2nd order at 400hz.

Using a large quantity of these will give power handling and semsitivity but it won't change the F3. I'd be sure to obtain the relevent specs and do a WinISD sim to be sure that they'll reach your intended F3.

Hmm, these "equipment speakers" usually have a diaphragm of stainless steel to make them more weather resistant. Not that a metal diaphragm has to be all bad (after all, titanium/beryllium/aluminium compression drivers can sound wonderful), but stainless steel... well I sort of have my doubts... Also fq response might be anything but flat.

But it sure would be interesting to see have 30 or more of these would perform in a LA! Keep us informed!

I think the chances of finding any graphs on these are gonna be next to impossible. But like I said $12 for 60 ain't a real bad investment even if there crap

Perhaps some Piezo's crossed over at 2KHz would take away any harshness these would probably have.

they are called Super-Thin Mylar Speakers i believe
