Quoted from athenspin:What’s the difference between the standard and premium upgrade on the pinball pro speakers?
Quoted from SeaLawyer:"The Premium high energy subwoofer is CHROME with a 50% bigger magnet and develops deeper/tighter bass than our regular subwoofer." Not sure why the explanation page on their website went away. Pulled this up with the Wayback Machine:

Maybe shoot ovfdfireman to verify it's still accurate?
Thanks for posting the info. We actually did not take it down, just moved it. it’s on every kit page as a link. next to where you select the model you want we have in bold orange “click here to view the premium high energy upgrade” which takes you here http://pinballpro.net/premium-upgrade/
Now it is easier to order and to find, because before placing the order you must select which version you want on each kit. Before you had to know it existed to buy it.
Here is the kit for T2 found here https://pinballpro.net/shop/williams-wpc-89-speaker-kit/
Hope that helps!
