JBL GTX subs

[king nothing 10+ year member]

Anyone have any info on the JBL GTX subs? specifically the 8s? I have 4 of them but cant find any info on them online. All I have is the info that came with the subs. They look nice, very much remind me of my old MTX thunder 7000s. 4 spoke cast basket. heavy simple black paper cone. Anybody know of or have any info on these?

I bump this thread - as I just got me a pair of them also.

seem beefy enough...

id like to find someone who has the specs sheet on them - that lets the user know ideal box sizing for sealed / ported / tuning ext...

along with powerhandling on each aplication.
