AV cabinet for large center channel.

The dimension of the center channel is 14"(H) x 38"(W) x 13"(D). 14 inch worth of opening does not seem to exist in any ready to order AV cabinets,  where the opening accommodates the speaker and levels to the ear. Putting the speaker at floor level seems like a waste.

Any pointers or even how to get one custom ordered?. Serious WAF issues with large center channel :( need help.
