BPD1503: What do you think the max it can handle for transients? (1 Viewer)

[Anthony_Gomez]

has anyone put any serious power into their 1503?

BPD sites says that it can handle 1000+ watts RMS...so how about transients like explosions in movies. How do you think it can handle the Depth charges of U571 at 2500watt explosions?

What are your box sizes again? Kinda hard to judge a trash cans volume

Rudy.....you know where you can shove it! .
I am not talking about the trashcan. I am talking about a single trashcan liner in a smaller can such that with 2500watts, the trach can liner willl just start to reach it's linear elastic limit

Damn PE trolls.

LOL to both of you
Tony, seriously what's the box size for your 1503's?
UniBox says you'll get out of Xmax @ ~40hz in a 2cf box with 2.5kw

Jack, those trollsstick to you like bubble stuck to the bottom of your shoe...only the gum is more pleasant
Rudy Troll:
I am looking at if I put a single 1503 in a 16"cube with 1.5" walls. Physical volume=32.7L. Heavily stuffed=39.6L
EffectiveQ=0.59
with the 2500watts peak of the K2, I could hit 106.5db @20hz anochaic...not bad for a 16" cube ..RMS of 1000watts= a continuous 102.6db@20hz

:frowning:
Excursion wise you'll be safe, but thermally....maybe if it's only the transient you should be okay.

I have a printout somewhere (the URL is gone) of an e-mail from Pat Morrisey to Rick C. from the PE board regarding actual Pe of the 1803. Pat said they had hammered the driver with 2000 watts for a while and it survived, so I think you'd be ok with those kinds of transients with the 1503 since it's the same motor. I think.

..damn test tones!!!

I was playing around a moment ago to see what type of volume I could get with my current system at 15hz. I was playing till the amp just started to clip...so 800-1000watts each (~105db anochaic). I was running from 15-20hz and only did this for less than 1 minute (probably 30 seconds), and I already feel queezy! I didn't really hear much, but the drivers were dancing..and I guess so were my innards!
