   hey,

I´ve build my first two xtro´s, and now I have to load them.
I´m asking me what woofer is the better choise. I`m not sure if the  B&C 15 nw76 is only a cheaper option wich isn´t as loud and kickfull. Or is the B&C 15 nw76 the better choise to load the xtro because it is louder and kickfuller?

	In the cost-less-for-about-the-same, you could consider the 15NDL76. It's at least as efficient as 15NW76 and 18S'nd 15ND930 in the 100Hz regions. Also 18S'nd 15NMB420 might work good.

	so the b&c 15nw76 is as loud as the 18sound 15 nd930? or is it louder? when i´m looking at the tsp i think the b&c has a bit more kick, is it right?

	I've been looking into this lately cause I'm making the 15" section of the xtro seperately. I did get the ndl76 and tried it on my test cab that is similar to the xtro. I think that the NW76 that has a higher BL would be a better choice. Here's the hornresp plots if it's any help, for the original xtro cabinet for one 15". nw76 =black nd930 = grey ndl76 = black nd930 = grey

	The 15NW76 will work fine in the Xtro, probably minimal difference between that and the 18Sound as the plots show. I use them in other cabs and they're great.

	do you think there is a big difference between the eighteensound and the ndl76 ? the eighteensound has: mms 101g, BL 23,8 and the ndl76 has: mms 96g, BL 22,5 has the eighteensound now much more kick or is it almost the same? greetz

	i reckon differences would be near indistinguishable by ear. if you can get nw76 for cheaper than the 18sound go for that option. the nw76 is a slightly more versatile driver than the ndl76 imo. if i was really concerned about getting the perfect driver i'd need to mount them both in the horn and do distortion comparisons. then i could find find out whether maybe the cone treatment is making a difference. maybe the b&c sounds sweeter higher in the range whereas the 18sound sounds better slightly lower as it acts as a piston better at lower frequencies. complete guess though, maybe im wrong and the b&c is just as rigid but not as shiny i don't think a db here or there on the frequency response curve would be the defining difference for me Edited by darkmatter - 31 July 2009 at 2:37pm
