hey guys

i need your help here.

i want to get a new subwoofer and i decided i want to go for an active subwoofer.

my 2 choices are

1 samson db 1800a 1000w 18" powered sub - ive used 2 of these for live sound before and they are really exellent.

2 studiomaster vpx15 600w 15" powered subs they look good and they are a nice price.

my problem is what sub/s would be better for mobile work
the samson one drops to 20hz and it has a nice high pass crossover that you can set via a frequency sweep control on the back.
but the studiomasters look nice and i could get 2 of them for the same price as 1 of the samson 18"s but will the studiomasters be better for mobile work or will 1 samson 18" be better for mobile work.

has any of you used the studiomaster vpx 15 subs if yes what are they like??
thanks alot

I can highly recommend the excellent RCF 905 or 902. 1000 watts of bass

Can't comment on the Studiomaster as the brand is relatively new since the demise of the original Studiomaster Diamond company of powered mixer and 'D' series amp fame.

The Samson powered speakers are quite nice, very loud, decent quality, though I'd dismiss the 20Hz thing because unless you're throwing oodles of power at it, you probably wont notice it in a venue from any single speaker that's small enough to be lifted by 1 person.
