Hi,

What sort of drivers would be best used, I would like to order from www.bkelec.com as I've dealt with them before, unless anyone else knows better in the UK. Budget would be about 200 for just drivers, I liked the look of two Fane Colossus 18B-600.

Intended to fill small venues with serious ammounts of bass. Amplifier will be made latter. I think would be good to have a lot of power around 60Hz to 150Hz. I thought Ported would be best too.

Anyone built large subs/bass bins? Thanks

I've delt with BK allot in the past 10 years, no problems.

You could go with the Eminence Kilomax 18" 200L enclosure tuned to 40Hz with 2 8" ports 18" long. With a 150Hz 6dB/Oct LP and a 35Hz 12dB/Octive HP protection filter, this unit would give about 128dB SPL at 1KW. with 6dB points of 40Hz and 136Hz, good chesty thump, with a good bottom end.

If your going for Bass, I would not use the Fane 600B, rather the 600XB which is more designed as a sub. you would have to contact fane to get the spec on this, or BK, as they would be happy to do that.

I actually meant 200 for two drivers, I probably didn't make that clear. It's quite confusing over the possible choices. I could go for two Kappa 18s or maybe four Delta 15s. The music that it'll be used for has both kicking bass, and also loud low basslines.

Maybe I should be widening my suppliers, anyone else know of good suppliers of subwoofers in UK. I can get Monacor drivers if anyone knows of any good ones (15 or 18 inch).

I'll design the amplifier around the speakers I think, bridged bipolar in rack case. Nice!

Thanks in advance, Lyndon

BK has some Wharfdale drivers going cheap at the moment. The 15" 300W driver TC15-300 is only 40 in the bargin corner.

http://www.bkelec.com/special/sp3.htm#tc15-300

Looks quite good tuned to 35Hz, with a 70L each. You will need a 30Hz HP filter to protect the driver, but thats normal on PA subs. Easily take 300W a driver, and you could afford four of them, giving an SPL of somewhere near 125-128dB from 40Hz up running the block at 1.2KW

If the Fane 18" have low moving mass then a Gauss 5181 Karlson-type might be a good choice - do a search for "Karlson homepage" to check construction of the 15" cabinet and also EV-Telex and request free plans for their 1970's Gauss 5181 cabinet - superfically it looks like the old Karlson box scaled ~1.1:1 but baffle tilt is a bit different at ~27 degrees - these would be reasonably compact/light built of plywood and 3-4'x8' sheets would yield one pair
