GRS 8PR-8 8" Polycone Rubber Surround Woofer

GRS 8PR-8 8" Polycone Rubber Surround Woofer

Q: If I'm planning to wire this with a tweeter, do I need to buy a crossover?

The crossover would really be for the tweeter. It protects the tweeter from low frequencies. The woofer doesn't need a crossover.

Q: Are they made with plastic or paper material? And do they distort at high volumes?

They are a silicon type material and they seem to hold up at higher volumes. Keep in mind that these are low cost speakers, they may not hold up in a high performance sound system. They are definitely an improvement over stock speakers in an old Sony cabinet.

Q: What is the mounting bolt circle diameter? Or what is the distance between the mounting holes (either diagonally or on one side)?

These replaced my woofers in my Advent II speakers from the 1990s. They sound great. Diagonally is 7.75". Side to side (and up down) is 5.5". Ned Chatt Jr.

What would you recommend as the high pass cross-over point on these speakers? i.e. frequencies below this point should go to a dedicated sub-woofer?
