Axiom Home Page Forums General Discussion Home Theater VP150 above a new plasma?

You could try Axiom to see if they can send you the insert, however, not sure how you would place it in position unless you could remove one of the front woofers to reach inside of the cabinet.

To answer your question, yes you can put a center above the screen as long as it is pointing towards the listeners. Idealy, it is best if the tweeters are lined up as close as possible with the left/right main tweeters.
