What size clamps? How many? And what brand of glue?
Ok, for a minimum glue up 4 18" clamps for duals and 6 if they are the triples but remember, that is bare minimum... more is always nice as you can add them to other places..... The dowels in the base / top / side panels take care of the alignment, so really, you only NEED to clamp across the braces to squeeze the cabinet together and from front brace to rear brace to keep them up against the baffle.
In Peter's video, you'll see I recommended assembling them upside down and not to glued the top on during the first step, it is actually done last.... instead, you want to glue the baffle, side panels, and braces using the top as a jig. Then the base to the exposed end facing up using the 4 dowels for alignment. The base has 4 counter sunk screws so no clamps required here.
Once the glue sets up, unclamp and flip the cabinet over (right side up). Now knock the unglued top off and glue it down using the 4 clamps (they'll clamp from the top to the braces) ... I'd use a small piece ctive piece of scrap between the clamps and face of cabinet top.
Titebond glue will be fine, or, get the Titebond Extends if you want a bit of extra open (work) time
