Posted March 25, 200817 yr I was wondering if the BP option changes anything on the T/S parameters of any woofer it gets done to?Does it lower efficiency? And if it does, what is the point?Does a subs BL drop by having the BP option?
March 25, 200817 yr Nope...just an aluminum plug in the pole to make it cool better...If you add cooling the parameters do change some, as there is less steel in the gap.
March 25, 200817 yr Author Ah, well that's good then.So even for someone to be on the safe side, getting bp is only an advantage.
March 27, 200817 yr No problems w/mine. It gets pushed hard and I've never bottomed it out or smelled coil. This thing is tough
