You said it does. Have to take you at your word.The thing is, no-one buys a Barefaced cab on a whim, and most email for advice, and I've learnt that the best approach is to be as precise and honest as possible with my analysis of what's needed, that way people get the cab they really want, and continue to spread good words about us.
Regarding high pass filters, you can use a separate one if you like but I can't see why anyone would need to use one with a Six10 and it's not something I hear from customers (and one of the big upsides of selling direct is we also get very direct feedback). Are you assuming that the Six10 has tons more low-end than an Ampeg 810 or have you heard one?
