A lot of players, hell, most of 'em, chase after speakers that colour the sound in a particular way, or 'break up' just so in response to a particular amp. To me that has at least one major drawback. This 'magic' confluence of amp settings and speaker characteristics only works for [u]one[/u] kind of sound, at one volume level.
If you drive your amp a little harder, it doesn't sound as good. Drive it a little less, it gets weak or flabby sounding. Arse!
I hold that if your amp sounds great, you sure as hell do not need a speaker that presumes to 'interpret' your amp for you. I chose my amps because they sound good. I use Weber California speakers because they deliver exactly what my amps send out to them. Efficiently. Loud as the voice of God. And no bull**** cone breakup or 'interpretation'.
