new Hi-Vi surplus drivers 3"

[ocool_15]

I just found these 2 3" drivers and was wondering if anybody has used them or has information on their frequency response beyond parts express's info.

I did not find them on Hi-Vi's site(only the A2S is listed in this series) and google turns up little info.

HI-VI A3SII SHIELDED ALUMINUM DRIVER PAIR
this mobile thread mentions them.

The less expensive ones look particularily interesting...

they both are patheticaly unefficient
i have not hear these particular ones, but my experience in general is that i do not like unefficient drivers
somehow they sound without life

I tend to agree with you ,,,, the problem with small drivers is that efficiency has cone area in the equation so the smaller the driver, the less likely it is to be efficient. And if that driver has lower Fs its efficiency goes down even further,

The efficiency of these is trypical of the class, the Fostex FE8x drivers probably being the most efficient.

check the pe message board, theres a post that has frequency response and impedance for the a3n. unfortunately none for the a3sii atm

I find at close to 85 db they are pretty typical spl, more than loud enough for a mid size room, if your families health is important and you dont want them to go deaf over the next few years, a wise choice.

A Line Array is one way to combat the inefficiency and these may well be suited to that purpose.

In my room, with my favorite amps having less than 5W, the 91/92 dB speakers i use are right at the edge of being efficient enuff.

Line arrarys have facinated me since i was a teen. But every time i do the math getting a single, better driver just seems to make more sense.

The fact that the line arrays i have heard -- with the exception of my acoustat 1+1s -- have not been very impressive hasn't helped at all either.

I was fortunate enough to get the spec sheets from Chris F at parts express.
The A3N driver actually suites my needs better.

I was looking for 100-150Hz in a 3" to above 4K hz
I already own the Tang Band W3 593S 3" driver 264-809. These are a 3 way design on my pc using a pair of surplus 5.25"and will likely keep the same Dayton ND20FA-6 275-030 tweeters. I am tri amped so sensitivity is not of much concern.

I also wanted something easy enough to reference to the common Hi-Vi B3S and B3N.
