Strong Speaker Pod Clamps
Crutchfield Customer Review (What's this?)
Overall these are very well built clamps and the range of sizes available fit most every pipe size used for marine applications. Fit and finish is very nice and hopefully will hold up to the environment over the years. I must say I was skeptical that these clamps would securely hold the speakers steady while traveling in rough seas, but JL Audio has engineered a very capable clamp/speaker pod system that doesn't allow any more movement than whatever they're clamped to. I would have liked to use the swivel-type clamps instead of the fixed, but the drawback with either option is the cost.....
Pros: + Very strong + Well constructed (fit & finish) + Looks good + Comes in variety of sizes
Cons: - COST!!!
