High Efficiency Loudspeakers

Wood cones are definitely worth exploring given there will inevitably be trade off between the usual gains and losses. Gains include slight increase in tonal density, losses include a slight loss of apparent speed.

My JVC mini system sounds fabulous, albeit on a small scale with a pair of wood cones bookshelves.

If this JVC blurb is to be believed birch seems to the best wood of choice.

I look at drivers voicing/accuracy/percision/soundstage, 1st,,,then i ck db #'s. SEAS has low db, but incredible hifidelidty,,even better db ratings are SB and possibly equal/superior. I choose speaker 1st, THEN amp. 

if you havea  $50K amp and a  2 cent sounding speaker =  2 cent sounding amp. Go figure. 

@mozartfan      You did say nothing new,  i agree for 100%. But 
seas exotic wide range is not expensive to compare Voxative especially wooden cones (3-4 times chipper ) and to make sure the yours is best , you have to listen other brands Cheers
