a question for the experts from JBL,
Excuse my English.
I have a home theater, JBL L-112 with front, rear and center for 4688 TCB cabinet low frequency(2240).
But I have a deficiency at the low-mid.
I would like the punch (kick bass) added at to the tcb 4688 (ultra low frequency)
Is it a good idea to add Jbl 4530 (with 2225) or Jbl 4648 which are mounted front speakers(front load).
What is the difference I would get with the speakers mounting " rear loading horns " and '' front load ".
thank you for also recommended for another model
