P.audio for 12" speaker

[hicksynet]

hi i am about to build a pair of 12" speakers the only place i can get speakers in Australia is http://www.cannonsound.com.au and they are having a sale on. These speakers will be coupled with 15" subs as well they are more of a party sort of thing with sub good grunt. i was just wondering first of all are any of these speakers/horns any good? also does anyone have any ideas?

and for the sub

im still not sure if i should go 15" sub or 18" i want to try and keep these as small as possible for transport.

i like the look of the HK speaker http://pro-music-news.com/html/02/e50412hk.htm

thanks in advance

the 15" are going to need a HUGE cab to respond low,
even the 12" will be pretty big ~ 100L /driver;
for party use, I'd forget the 15" and go for 2x 12" per side.
If you want portability I'd think about using closed boxes and electronic equalization to get good LF response
Prices are nice
