I'm possibly going to build a new 620 cabinet...but I note the braching is mainly composed of 'on wall' method, with one single front to rear brace near the driver.

Would it pay to add cross braching in two or three places using panels with cut-outs....or best to keep the single large void per the original?

In other words, could the cross-cabinet braces adversely affect the bass response?

Kindly

Andrew.
