I'm moving to a new office and I'll have space for speakers literally on a bookshelf that's 14.5" deep. Out of respect for the office below me, no sub.

I'd like to get the 340s, but that's only 4" of clearance behind the speaker. Is that enough or will the bass get boomy or otherwise unhappy? Or are there plugs for the 340s like there there are for the Sierra-1s?

(P.S. I'd love to do the front-ported Lunas but the budget does not extend that far.)
