P-Audio SN 15MB Dis-continued!

   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!

	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

	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
