I want to in the Future get a more powerful poweramp,and some bass bins 15 inch or 18 inch with built in passive crossovers.But I need portable bass bins and a poweramp for no more than £1000 pair,which can fit in a small van with the rest of my dj equipment.

I heard Scoop bass bins are very good sounding,but even the 15 inch version are still large.A friend of mine has a pair of scoop bass bins made of 18mm plywood,loaded with FANE Collossus 15 XB,they sound awesome.And he has an amazing Crown Macrotech poweramp with 2x 600w rms into 8 ohm.
Or I could buy some smaller 15 inch bass reflex bass bins,but bass reflex design is inefficent.
Also W bins,and J bins are very good,but I heard they are expensive,so I could either build my own or get twice as much bass reflex bass bins[£400 pair with Eminence Kappa pro 15 lf 500wrms].
What do others suggest? My Main speakers are AC EURO AC115D[450w rms each,Eminence Delta 15 and Fane 1 inch comp],And my Poweramp is the Gemini X3[2x 300w rms into 8 ohm]

i use the Proel Smart15 system which is 2 x 15" top & Mid + 2 x 15" sub bass bins, very light & I get them in the back of a Suzuki Vitara. under £900 retail I think. But Chris will let you know

Wouldnt advise scoop bins for general mobile work - firstly there huge, secondly there long throw, and thirdly there best off playing techno. I would opt for a pair of shelf ported 15's from proel or DAS or something - if u want a simple solution (althought i think these bins are appauling) then u could always go for a pair - or even 1 - of hte mackie active subs

But the Mackie bins do have sexy blue siganl lights though!!!......
