Hello all , this is my first of what I hope is many posts to this great site . I have some JBL 4311B speakers that have tears in the mid range cones . I am wanting to know if some of the other mid range numbered speakers are the same or what ? My mid's have the number LE5-10 on the backs . I see others for sale that are LE5-6 and they say they will work . Are they the same ? They look the same . A bit confused . Thanks for any help , Dan
