84dB/watt is not "hard to drive", speakers which are hard to drive are those with low impedance and/or big phase shifts which demand a lot from an amplifier and some modest amps can not deliver the required current.
A low efficiency speaker with a benign impedance curve is not hard to drive it just needs more power for a given loudness and the small low impedance speakers tend to have a lower maximum loudness simply because the amount of power you can put into a small driver before damage is usually less too.
My LS50s are not hard to drive but they are small, they will go louder than the LS3/5a they replaced but nothing like bigger speakers.
Gotcha well I should be fine with my little amp than, this is why I like this site because you guys use science and not magic, lol. Everyone I’ve talked to said they LS50's need 200+ watts with no reasoning behind their statement, unless im running bass boost (which i wont be, if anything ill run a crossover at 100hz) and listen at normal volumes of 75-85DB I dont see how that adds up. Since this is really a 4 ohm speaker would that not be better for me because my amp puts out 60 watts at 4 ohms instead of 45 at 8 ohms. Its harder on the amp but its designed for it so i dont see the problem here and the fact that its 4 ohm seems beneficial.
im really after a 3D/holographic soundstage and imaging, so im hoping the ls50s have that. Im also looking at the totem Skylight but i heard on here they sound bad, on the flip side the formal reviews i read said they were great and offer up 3 dimensional sound. In either case im less concerned about total accuracy and more interested in the former.
