HELP in SUB

[cristiano]

Hi,

I need some help to choose a subwoofer kit. It's my first project...
Every thing coming from USA is very expensive.
I'm thinking in 22/500 from http://www.lautsprechershop.de/.
Is a Detonation DT500 with 2 Alcone AC 12 SW8.
The all parts without wood (EUR 779,00)
Is this a goog sub?
Is this a good price?

Thanks,
