What are specs for Mirage BPS-100 subwoofer drivers

[mokus]

Hi there,

I just got a pair of replacement drivers for a Mirage BPS-100 subwoofer.

Does anyone know where I can find any specifications on them? The person I bought them from didn't know anything about them other than the model they were used in.

I've found the manual for the model: http://www.miragespeakers.com/PDFs/classic_manuals/Subwoofers/BPS-100/BPS100manual.pdf

On the back of each driver is a sticker with the following printed on it:
4DR51803-A
P95B3
MADE IN CANADA

They each weigh about 1.1kg and the diameter of the metal frame is 16.5cm

Does anybody know anything about these drivers?

By extension, does anyone have any cabinet suggestions for them.

They'll be used along side a pair of full range speakers using tangband W3-871 drivers. The cabinet details are described on http://www.zaphaudio.com/archives.html

As far as cabinet size/porting , I have no preferences. I know it will depend on the characteristics of these drivers.

I presume I'm going to need a plate amp for them and am looking at either the CSS SUB 100 http://www.creativesound.ca/details.php?model=SUB100

or the CSS BASH 300

I'm not looking for or expecting mind-numbing bass out of them. Most or the music we listen to is symphonic and acoustic with a healthy dose of Tom Waits.

If anyone has any information about the drivers and any suggestions about the cabinet size, I love to hear your thoughts.

Thanks in advance.

This is a picture of the front and back of the drivers:

Well as a guess, in the manual it states the external dimentions why not built a replica.

Thanks for the suggestion

I'd thought of that but from looking at the specs I don't know if the box is ported or not, if the speakers are in series or parallel.

I also can't tell how the inside of the cabinet is arranged.

Some info the its Bipolar nature.

It looks to be a sealed unit.

If you want to know about series or parrallel wiring get a multimeter and measure the impedence of one of the drivers, that will then tell you what your options are.

Thanks for the links to the bipolar design.

Because the cabinet is sealed, am I correct in thinking that the inside of the cabinet is basically an empty box with a bit of bracing?

Any thoughts on the 2 amplifiers that I'm considering, the CSS SUB 100:

or the CSS BASH 300

I've read good things about the BASH amps but would it be overkill for the drivers that I'm going to be using?

After some hunting, I found a deal on an amp for this subwoofer project and just picked up one of CSS' amp, the http://www.creativesound.ca/details.php?model=SUB250R

As I still haven't found any real specification on these drivers, I've decided to reproduce the original subwoofer cabinet as much as I can.

Does anyone know if the cabinet's interior would be one continuous space or if there's a wall dividing the interior into two separate cabinets?

Any suggestions on how much stuffing should be put in the cabinet?
