Original 604-8K or GPA 604-8H-III

I hope you build them quickly and love them!. I've got refurbed 604Cs and the Bison plans. I trust the change in drivers would not be very different in the same cabs. If you do the bottom port option, there should be good (not visible) tuneability. Your experience will influence my go/nogo decision.

I'll likely be pulling the trigger on the GPA drivers next and dropping them into my cabs while I work out the Bison build... I'll keep you posted.

Can?t give a direct comparison as it?s been many years since I?ve heard a 8K. I can say the GPA 8H III in a 620 cab sounds incredible. I?ve thought about upgrading the stock fixed crossover but then answer my own question with a why.
