okay so i have an old three stack magnet btl twelve if i bought a new single stack btl 12 would it be worth it thanks.

worth it how? What do you want it to do?

I doubt it if your just going to replacing the one you have now, I know they made upgrades to it but nothing that the ear will hear.

I would not run them together if that is what you're asking.

no i was just going to replace it

While we like to make sales, I'm the first to tell a customer not to pay for an upgrade or option if it truly isn't needed. In this case, I wouldn't do it. Only a ever so slight motor advantage with the new singles, and some soft parts upgrades (especially if you have a really old 3 stack). If your current sub gets too tired, a recone will make it like new.

Thanks,

Scott
