GPA N604-8A crossovers, $300 US for the pair. The 8C version with attenuators cost $240 USD each.


I bought these new from GPA with my 8H-III several years ago, and they have been sitting on my cupboard shelf for most of the time as I used a custom xo for my custom 10 cu ft cabs.


The N604-8A Crossover is suitable for use with any Altec Lansing 604-series loudspeakers. The 604-8G, 604-8H, 604-8K, and 904 series loudspeakers all perform well using this crossover.
