Below the point where baffle width = wavelength, I've heard that the efficiency drops. Anything below about 300 Hz (a baffle width of about 3.5 ft) would be about - 6 db.
But I've also heard that open baffle bass sounds great.
How would you describe the quality of the PHL 18" open baffle bass???

The size of the unit is so large as to overcome alot of the open baffle cancelation. Its like a 18" open is like a good 12" in sealed.
That is I know the 18" would sound much more forceful, deeper if it was in an enclosure, but that enclosure would be bigger than a refrig and possibly too much for the other drivers. In the config above the 18 did a fine job.
