Height is irrelivant however cu ft is of course. Cosmetics will dictate what sacrifice you make to keep volume of the box the same while keeping the height you want. 9 inches should be doable but you may find it neccessary to have the cabinet wider or deeper than the stock La Scala. I have had the best luck with a slot port, il try to post some pics of what I did, seems now the challenge is keeping light bulbs from breaking the filaments now.
