A family friend recently passed and left some gear behind which is making its way to me. He played both guitar and bass, but the family doesn't know what this cab was for. It's clearly semi-recent (made in the late 90's at the earliest, I think) but doesn't have any identifying markings on the outside so I'm thinking it might be homemade. I've seen some pictures but still no pertinent details. I'm hoping I can look up the speaker model when I receive it to find specifications. I've heard that speaker/cone (?) travel distance has a lot to do with how well a speaker can stand up to bass frequencies, but looking up other speakers I don't see any numbers representing that specifically. What should I be looking for in the information I find?
