hi! just thoght i put up a thread where all can say which speaker is the best you´ve ever heard & why. me myself have´nt heard heard the top of the line jbl:s. the ones i got a chance to hear are. L-19, L-50, L-100, L-110 ,L-200B, 4311, 4315 & jubal. in my opinion the 4315was the best. can only imagine the sound of the 4343 or 4430.
