What would suit best ?

[aft]

Hi all,

I'm currently building my 3-ways loudspeaker (separate cabinet for bass and Medium+Tweeter) based on the following speakers
Scanspeak D2905, 18W/8545K00, 25W/8561 all are 8ohms nominal except the tweeter that is rated at 6Ohms.

The sensitivity of the loudspeaker is in the range of 88-89dB.

All this stuff is going to be installed in a 45 squaremeters room.

I have been looking during hours to the amplifier that would suit the best, reading post after post (learnt a lot bye the way)
but unfortunately I'm not yet at that stage !

My main concern is around power required, are 10 watts Class-A sufficient or shall I look to an more powerfull Class AB amplifier.

Other question is the importance of the dumping factor, shall I look to a specific range, knowing that I'm listening to various
lounge music where bass can be quit strong !

I would really appreciate your advises.
For your information I have posted my question in the PassLab area as well.
Thanks, Raoul
