Well after reading all the reviews here I just ordered a pair from Amazon.Figure for 54 bucks to my door worth a try.I have the old model J&M's and have been happy with them will put my thoughts here how I feel about the JBL's after I get them in.
From all the positive reviews on this thread on the JBL GTO 638 speakers, I pulled the trigger. I purchased from Amazon for $54.95 plus shipping, a total of about $64.00. Thanks to everyone who contributed to this thread.
The GTO638's arrived @ an hour ago.
The GTO638's are marked as 2 Ohm speakers, but measure @ 2.8 Ohms according to Mr. Fluke.
The OEM woofers are marked as 3.8 Ohms, but measure @ 3.3 Ohms according to Mr. Fluke.
One other minor observation. The Tweeter/Midrange stalk is fixed and you have to mount them upside down. Being such, you can not balance the treble with both tweeters either on the inside or the outside.
