Driver for Dr 280

[aricabral]

If I was going to go to the effort to build a DR280, I would be putting recommended drivers in it...

Thank you Brant
I think the same as you, but unfortunately the recommended driver is not available here...

Where in South America are you?

Argentina

Eminence USA tells me that there is a distributor in Argentina.

Grant, thank you for the information
The problem here is that the Goverment has limited al the imported articles and there are a lot of stores that do sell eminence, but no one has stock
I have just called Todo Musica (didn¨t hear about them before) and they told me they are out of stock, but may be they will receive some units by year end, so good news I think...I´ll wait

Than you!
