I just looked at various forums n different discussions about Flipper Fidelity speaker kits versus Pinball Pro and it seems a 50/50 with all sides saying their choice is the best, which means its a 50/50 on opinions.

It seems that this seller, with the link I have enclosed below, is cheaper for the Pinball Pro product, versus the Flipper Fidelity pricing P/L has.
Theres barely anything in it $.
