After much hesistation back and forth, I've finally gone ahead and purchased a 2nd hand Behringer ep 2500 to run an 18" sub.
I live in New Zealand and my original plan was to buy a stereo integrity 18" sub and import it with their resonable shipping costs. But just this morning I came accross a blaupunkt VPW-460 18" sub for sale and I snapped it up for a good price. Now I'm trying to understand if this sub will be comparable to the SI 18". The first thing I noticed is that the Blaupunkt's power handling is much higher, some 1800w rms. I figure the ep2500 should drive this nicely bridged at 4ohms.
But when I look through the specs they are quite varied so can someone please shed some light on the sound characteristics of these speakers ? At a guess I'd say the Blaupunkt will have more punch but not reach as low ? I'm yet to fully understand what all the listed specs mean. My intended sound from this speaker is for low rumbling bass for explisions etc for movies. So I want it to play as low as possible. Punchy bass not a priority.
