The paper Frank linked to takes interference effects into account (as distinguished from room reflection effects -- as you may realize they are two different things), and states that on average there will be a 3db increase, with a range between 0 and 6db depending on the interference effects at the exact listening position and frequencies.

Hello Al,
This is what i was alluding to when you measure using a typical 2 channel setup ( hi-fi application ) the localization and summation of both channels lead to 4.5-6 db increase in SPL from the listening position. The 3 db as per previously discussed only applies to free space.
Regards,
