I'm guessing that this is also a function of the speaker motor.  For example, my Altecs are very highly damped due to a very large magnet, so I would think they require less damping factor from the amp than a smaller-magnet 15".

Isn´t this why tubes work so well with fullrange speakers? Most fullrangers are highly damped due to the big/strong magnet and don´t sound so good with highly-damped amps like most of the SS verity
