Ive built two HD15 a while ago, but at the time of building I didnt have the money for the right drivers. I just used some crappy 15'' that doesnt work well with HD15.. anyways, I have the money to buy some drivers now.

Since my HD15s are supposed for outdoor use, during festivals, Im looking for a high SPL rather than super sound quality.  Bearing that in mind, should i still go for the PD154 or instead pd1550?

PD1550 seems to be able to handle more watts, but Im a bit confused, cause the PD1550 magnet is smaller than the PD154. Does anyone know which of the two is better for max SPL?

Having looked at all the plans on this site, it seems to me that the HD15s are some of the best horns/subs for max SPL? It peaks at 108dB.

Looking forward to your replies

154 hit subjective harder/harsher, 1550 more "musical".
That´s my experience in one sentence, hopethis helps a little...
Who the fu&k is Mr. Phanton, and why he has so much power!?

Thanks

An important thing i forgot to mention; its all run by truck batteries, thats why output is so important rather than quality. 

The amp I want to run the HD15s with is a Genesis Sub 2x350watt 4ohm

+1, never actually heard any of the two in hd15 but just by looking at the specs of both drivers i would say that above may well be very true. 

pd1550 vs pd154, lower fs, higher vas, higher cms, slightly higher xmax.

Best regards,
Teun.
