Bookshelf speakers-double up,kef ls 50


I would like to ask,could I get increased performance,if I put one pair of book shelf speakers on top of another pair.My amp is powerful enough.Im using kef ls 50,and would consider getting another pair if things will shine.Thankyou

Oops. Sorry, I meant SVS SB12s that go for $1149 per pair. The SB13s are over twice the price. My bad.

Good Good,Yes I have 2 pre outs on my Ar ref 5 linestage,I prefer balanced.There seems to be some well reviewed subs around,but Ive never owned one with small speakers.Thankyou for your good suggestions.I'll get in there,and see how these ls50 sound, and go from there.My other speakers, Im yet to sell,take 2 people each to lift,so im down sizing you could say.
Hi there,I have just connected up another pair of book shelves.A pair of tannoy mx1,to the kefs, just to know.Im getting alot more weight,a fuller sound.Its good too,the amp is taking it,in its stride.This just mite do the trick,for now anyway.Thankyou for all suggestions.
The fewer the point source, the better the sound, that's the whole point of the LS50...

Go for a Rythmik F15HP subwoofer, you will be amazed how deep it goes.
