Can someone give some input on speaker configuration for the JBL Metregon? I very close friend has left me his Metregon's, one I get to keep the other has to go to the estate. The first one, system 205 has 275 horns and 130A woofers, which he owned from new, the cabinet is stunning! The second, system S72 has LE85 horns and LE15A woofers, which belonged to his friend, also nice, a little later and satin /matt finish. For a new audiophile (me) will there be any noticeable difference in the sound between the two system, assuming all speakers are working as they should?

Looking forward to hearing experienced advice.
