Subject: P-Audio SN 15MB Dis-continued!
Date Posted: 09 April 2013 at 11:42am
I was planning on making the X 15 plan on this site, but it seams the P-Audio SN 15MB is dis-continued on blue aran, so wondering which is the best alternative? Blue Aran states that this was a 300w driver and there are now 2 p-audio drivers at 300w:

P Audio E15-300S 15 Inch 300W - 40hz to 2000hz.

P-Audio 15BM-300B 15 inch 300W - 45hz to 3500hz.

There was no specifications on blue aran for the discontinued one but someone stated in this forum the frequency range was 35 - 3000hz. So would the (P-Audio 15BM-300B 15 inch 300W - 45hz to 3500hz) be most suited.

As the specs are different would the box be no longer suited?

Many thanks.

people have said the eminence kappalite are a good swap for these. i have tried kappa pro15a in place of these and they didn't sound as nice. there's a good few threads about these drivers... search it up

Anybody tried the new SN models (Series II)? A friend has a couple of 2 x 15" + 2" cabs with the original 15MB and I´m a big fan of the old SN12B/MB. I have over a dozen of them around in various cabs and they sound great. Also yet to blow any, very impressive! Smile

I´m also a bit sceptical about the Series II - it looks to me like P-Audio have sacrificed sensitivity for the (stupid) watts game - a bit disappointing, but maybe someone can tell me something different?

There is a possibility of bringing back the original SN MB drivers, only hurdle is a minimum order quantity of 100 drivers - it's no longer a current model for P-Audio.

they are a great driver... no chance of some replacement baskets (recone) for them, andy?

I think the recones face the same problem as the drivers, Minimum Order Quantity.
 
We could look into getting a combined batch of drivers and recones and see if they will do that, but they generally wont consider any special build of less than 100 pieces.
 
Its something I am considering, but there needs to be sufficient demand.

I'm halfway through reconing a pair of SN15MB's, P-Audio can supply the recone kits....

I don't think there was much issue ordering them, they're just not on the standard price lists, you have to ask.  If you look at the paperwork for the last but one order, you should find them.

The most recent  response on anything 'discontinued' was a categorical no unless it's 100 pcs or more. I'll have to check on the SN15MB recone kits, they may be a special case.

Thanks for your reply, I have compared the parameters and the P-Audio 15BM-300B 15" 300W would seam to be the closest match but the paramaters are not exactly the same, but I do not understand how to use the parameters to calculate if the box will work for the newer model? Do you think it will work ok without modificaton. I understand that there is an optimum air volume you want inside and the port length size is important!

P-Audio SN 15MB 300w old model:

Thiele-Small Parameters  
Resonant Fequency (fs) 47 Hz
Impedance (Re) 5.5 ohms

Equivalent Resistance of Mech. Suspension Loss (Rms) N/A
Efficiency Bandwidth Product (EBP) 151
Voice Coil Overhang (Xmax) 3.5mm
Surface Area of Cone (Sd) 907cm2


P-Audio 15BM-300B 15" 300W New model:

Re.....................................................................................5.7
Fs...................................................................................48hz

Many thanks - Simon.

winisd pro is the (free) software you want.

don't get hung up on the wattage.. it's not an important specification really.

where did you get to reesi?

i'd be interested in any recommendations of drivers for the X15 - the SN15MB is long long gone now, and p audio kit is hard to get hold of in the UK atm

did you not get a driver?

i replaced some sn15mb in some xm15s with bms 15n620 for a while... they are good. think people also used to say eminence kappalite were also appropriate replacements

also aware that if anything happens there's no way to recone it seems...

i got spooked bringing it back on the plane, figured airport security might not be kind about a large magnet... didn't want to risk losing it.

hopefully a friend will be driving over before the year is out!

thanks for sending it earplug :)

in the mean time i guess i'll start poking about with drivers for the X15, good exploration time to be had perhaps.

nice springy neos being first port of call

Aaah ok - as long as you do find a use for it. It is a good driver.  Smile
