I got my pair of 580's and unboxed them.
JBL could learn a little about packing and presentation from Klipsch. I would consider my RF-82 II's to be roughly in the same class. I will be comparing these two speakers in the near future, but first impressions matter and the Klipsch packaging and unpacking instructions allowed me to feel like I got something special while the JBL was thoroughly utilitarian. There is no significant cost to having better unpacking instruction on the exterior of the box. From a practical standpoint, this is not a big deal because you only unpack them once, but if I was JBL, I would want my customers to be as proud of their purchase as possible to reduce the incidence of returns!
They have an interesting panel to act as the lower section of the waveguide if you prefer to leave the grill off of the mid-woofers.
The upper pic shows w/o & with grill, the lower pic shows this panel installed (and an interesting speaker stand in the background - looks like a very small Martin-Logan sub for the base):
Unfortunately one of these panels is defective - it looks like one of the mounting pins was mashed while it was still hot - right after coming out of the molding machine and there is no way to align/install this panel!
Normally, I would follow the normal retarded system of returning the entire speaker to get a functioning panel! However, since these are out of stock, I don't want to end up with a single speaker!
Question #1 - Does anyone have ideas on how to contact JBL directly to get a replacement part sent? I think Sound Designs was the seller, but figure JBL is who ultimately will replace the panel. Not sure I will ever use it, but I want the speakers to be whole in case I sell them.
Question #2 - The crossover is at 1500kHz. Will the removal of the grill over the mid drivers have an audible effect? I generally think of grills as effecting the higher frequencies, but don't know what frequencies would likely be compromised by the grill.
Question #3 - Often, with dual woofers, one is a mid-woof and the other is only a woofer. However only one crossover frequency is specified so I assume there is no BSC (baffle step compensation). Does the use of a compression tweeter with horn somehow eliminate the need for BSC? (FWIW, the Klipsch does not have BSC either)
