This may be a sore subject for some, not trying to ruffle feathers, but some are telling me I can upgrade the crossovers to accept 198's an some telling me you can't?? Now, I have never heard either, so not sure it would make a difference one way or the other, so looking to see what some here have to say. That and if I were to only change out one tweeter in each speaker to a 194 would it make a noticeable improvement, or do I need to do all 4 to hear that improvement....?....or is the change so minimal that my beat up ole ears wouldn't know any difference. Thanks and hope to hear from members that really know!

Thanks Big Dawg, will do, but this thread is 1B activated and hope it stays that way. No control over that and still plan to read all 5 pages of the mentioned thread. Looking to see if the 2 members I am talking to are involved there as well."if it's not fun, it's not worth it & remember folks, "It's All About The Music"!!

Reading that thread seems like it could be done...

The 1B high frequency circuit is basically the same as the blade/blade SDA SRS 2.Political Correctness'.........defined

Identical except for one resistor on each HF board. 1B uses a 2-ohm resistor where the SRS 2 uses a 3.5 ohm resistor. My 1Bs don't have enough treble, I think a 1.5 or 1.8 ohm resistor in that place would be better.The 1B high frequency circuit is basically the same as the blade/blade SDA SRS 2.
LF boards are just plain identical between the two models.
