Page 1 of Eltax Silverstone 110 speakers, any good?

Hi,
Currys are selling an end of line Eltax Silverstone 110 bookshelf speakers (pair) for £25 (RRP=£120).

Music Power: 110W
Sinus Power: 65W
Feq Response : 50-20,000 Hz
Impedence : 4-8 Ohm

I bought them as the price looked very attractive but dont know if they are any good. Could not find any reference to them on the Eltax web site. Any one out there have any information about them please?

BTW: what is the Sinus Power?

They also have a pair of Mission DM7 with stands for £100. Are they any good?

Cheers

Jaf
