200 watts @ 8ohms would require a 8ohm loudspeaker of 89db sensitivity to achieve an 105db

89db sensitivity 1 watt 1 meter means it gets 89db with just 1 watt
92db = 2w
95db = 4w
98db = 8w
101db 16 watts
104db 32 watts
107db 64 watts

I don't see any need for more than 50 watts for your necessity. If the amplifier is rated 50 watts and has an equivelancy at 4 ohms (a 4 ohm tap for many tube amps) then this is all the speaker requires.

Most speakers on the market can't handle 325 watts - in fact most speakers can't handle 200 usable watts.

The best speakers that I have heard do not require more than about 30 watts and the best amplifiers I have heard are 50 watts or less (a lot less).
