I'm not so ok with you eric you saw your signature aprcie jbl lot and I understand you "preached in your parish." It is true that the orrigine c'tait a woofer jbl jbl in boxes which recess is logical but if you compare the specifications of JBL K151, E155, 2240 or even 2242 (which could be mounted of origin in 4818) with that of the FCR L18S800 home CHARACTERISTICS are similar to telephone marketing as well say, the biggest diffrence is with the power which is almost double that of jbl woofer that is why j I chose this MODEL stronger than jbl (cash and seen the power that I shoot with amps dja very big.
