AA is this the cab from Bowtie ?
Yeah, except for the parallel walls that can't be damped enough without screwing up its response, though using a 300 Hz XO like it was initially designed for mostly solves the problem.Quote:

A 'shootout' with one of DSL's larger Synergy horns would be interesting, though theoretically the latter should perform better overall, but my 'burning' question is would it be enough to justify all the extra time, cost, labor?

edit: AB, can all the info on his site be added for posterity to the Altec library?

When I look at that cabinet, I always feel like putting two cross members across the mouth to stabilize and break up resonances in those large side panels. 2x2s would do it.
Sure is. He has one more which I'm hoping to pick up by the end of next summer. Now I just gotta figger out what to pay him.....Quote:

Don't know what the minimum wood size is for sure, just know that I got excellent results with the scrap I had.
They really 'color' the sound otherwise, though after decades of even what little was left got to where it was sometimes too distracting, so will never again recommend/use a parallel wall horn except possibly a true 'sub'.

That's even better you get them with no price included ! :biggrin2:Quote:

I have to get together with Todd on this... The most important thing is that we can import a copy of the Altec User Board database to a new server from 12/2002 till now 9/2015. IME we CAN NOT lose all the information in this forum as that would be disastrous for us.. From my chats with Steven IIRC he makes a back up of the database once a week..
Right now I'm using my Dropbox account for the Altec User Board Library..Once we have a new server or move the library to Todds site we will have a much larger storage capacity for the Library.I'll keep you in the loop.
