2.1 set-up

I have decided to upgrade from my edfier s730, there are no complete 2.1 sets more powerful than the s730 so i'll have to piece together my own i going for power and bass, the source will be my fiio e7/e9 or i have a m-audio audiophile usb with volume controled rca outs.

For the stereo speakers i am thinking of going with these http://www.djsuperstore.co.uk/=froogle/item/amplifier-speaker-packages/p03706822_3-sound-pack-package-package  , these have a nice crisp clear bass heavy sound and are a bargin for £129 i'm pretty settled with these.

For the sub-woofer i am thinking of going with this http://www.htfr.com/more-info/MR384971 , it's a 12" so should go lower than the s730's 10", the problem is there are very few subs too choose from in the uk that have rca in & out.

Can anyone suggest anything else thats avaible in the uk, for the 2.0 speakers i am looking to spend up to £150 and for the sub £250, the 2.0 must have at least 5" drivers and be 50+watts each , the sub must be 10"+ and 100+watts and go down to atleast 35hz at +3db and have rca in and outs.

I'm not really looking for passive speakers as i would have to buy a amp aswell and it would add up to more than i'm willing to spend.

I ordered the kam soundpack 5 , so not sure on the sub the choice is between the QTX QM 12S and samson resolv 120a, the qtx has a 12"driver and goes down to 32hz before a -3db drop , the samson uses a 10" long throw and goes down to 30hz before a -3db drop i have the freq responce graph for the samson here,

According to some reviews the kam soundpack sounds awful, so i cancaled my order i now want 2 powerful loud bookshelf speakers and an amp, i brought the amp a alesis ra 300 http://www.alesis.com/ra300 , i got it for £55 used, now i need some speakers to go with it i have £150 to spend i am considering these http://www.htfr.com/more-info/MR98786 , any other suggestions i need volume power and a clean clear sound.
