Bass speakers for an event

If you have a problem, if no one else can help, and if you can find them, maybe you can hire the S-Team. (S being speaker... as in the members of this forum who seem to be speaker gods from what i have read)

anyway, joking aside.... id like to point out straight of the bat that I'm a lighting technician, the most experience i really have with speakers is my surround sound in my room. and yet I'm now being asked to source enough bass speakers to fill a medium school auditorium on a shoestring budget...
basically, I'm running events at my school (year 11) in the hall (floor space: 11m x 19m approx..) and i need to source some speakers, new, used, anything. i have found a pair of Wharfdale EVP-X15B's while the moneys right, i have no real idea whether they would be adequate. it only really matters that i fill about 3/4 of the hall from the front with a basic rumble from the speakers.

oh and to make matters more complicated (to me anyway, this is probably to you like doing 1+1 is for me), i need to also get an amplifier for them. which of course i have no ideas about either.

the information i can tell you (which is all that i know) is that the room has installed 4x wharfdale pro titan 12"/15" (cannot remember which) speakers, they are running of amps mounted on a small flight case the school mainly uses as an exam desk/writing table/drinks bar, basically a table.
anyway, i do not know what amps the school use unfortunately, but to my knowledge they only have enough ones to power these four speakers.
the type of music we would be playing is 99% hard style (same type of music (if not the same music) as they play at the Defqon.1 festival) and it is all recorded/digitally created.

so is there anyone here who could give me some information, in case you don't realise my knowledge is in the lighting side of things and i have absolutely no idea what I'm doing when it comes to speakers other than what sounds good and what doesn't in terms of volumes.

A pair or 2 of 15" or 18" reflex boxes should do the job, depends on how much rumble your after.

while I'm on the subject of timings (just re-read your reply), due to the lengths of cable going to the built in speakers, the delay on the subs shouldn't be a problem. they all have about the same distance of cabling.

Edit : ooops

FInd a pair of used JBL JRX 125 on ebay. Thats the 2x15 ones, pay up to 200

Look on the Wanted Section of here under 3 amps wanted, the Deja Ibiza post has a T&M amp 700w a side for 175quid, ask him for some leads :)
Now you need a mixer or music source, NOT directly into amp

As an upgrade later
Call Blue Aran and buy 2 x Beyma CD10 fe compression drivers and screw adapters, swap them out for the JBL ones and sell them on eBay

One kids PA system, no crossovers, no hassle for 400 quid
