What is this driver good for ?

[Aucosticraft]

A friend of mine gave me this unused diver.

I tried using WInISD, but could not understand what this driver must be designed for? When with closed enclosure, It gives over 200liters.

the TS are as follows.

Qts : 0.718
Vas: 57.7L
Fs: 40Hz
BL:6.2
xmax:3.8mm

(TS is provided by him. he says seller gave him those. )

What do you think what is this driver good for ?

OB woofer? How big is it?

[sreten]

Hi,

Its sealed mildly peaking (max efficiency alignnment woofer) probably 12"
Designed to work in a stuffed~ 30L (qbox=~ 1.2) to 60L (qbox = ~ 1).

rgds, sreten.

OB/IB is possible of course.

Ditto TL.

Xmax only 3.3 would not be a very powerful sub unless it's pretty large diameter.

OB, Can you give us a few more hints? Size, material, picture? You are asking too much with too little.

Thank you all for showing interest in this thread.

I did simulate using WinIsd, but it limits lower to nearly 45 Hz. But the Xmax is low too. I think what you said would make it more practical. BTW max power rated is 75W

I am titaly new to TL, but would be interested. Can I request you to suggest me the enclosure parameters (rough).

Its a paper cone. I will upload Pic tomorrow morning. also I have plans to measure its TS myself. ( my desktop monitor, which has LIMP installed has some problem.)

thanks again to you all. More words are welcome.

Sounds like an excellent candidate for a big midrange in a big system [think 15" woofer or more]. Consider using it in a "holey" or open back system. The high Q units seem to perform well in those. Looks like an XO of around 150 - 200 might work for power handling. How high can it go? That can determine the cost of the tweeter.

Post some pics please.

[Aucosticraft]

Just a curious thought. did you want the pics for the size of magnet ?

I am habitual of listening drivers when I get them. I take my ear close to it. and play some music at a audible level. I heard many but this one had a good tight deep bass. and a clean vocal. I know its foolish to listen this way but just have put it here, if it could point out something.

[GM]

Not me, just waiting on specs.

Ok, GM.

I don't have rest of the specs readily available. I would be measuring those at the weekend. ( In couple of days I should get my desktop monitor repaired. and unfortunately my laptop don't support Aux or line in for making LIMP to work.)
