Hi i am going to be purchasing athena f-2's today at best buy for 179 plus i have a 12% off coupon. They close in 3 hours so i need opinions. i have a harmon kardon avr 320 w/ a set of JBL nsp 24 all around with a jbl center channel that came in a 5 speaker set. Believe they were the NSP-II sets and i do have a 12" Sony sub. Anyways the F-2 after reading many good reviews, will they go with my JBL center or should i purchase the Athena centers today too? i was reading something about timbres matching? Dunno what that means. Thx any help is appreciated.
