I like my test speakers, a 2 way design with an inward firing 12" woofer crossed over at ~170hz to a modified full range driver (frd). The woofer I wanted had specs that required a large box, 4.5 cu ft in my case. The overall design provides several advantages.
1. As mentioned in an earlier post, a cohesiveness of the sound from a single driver across the ultra sensitive
midrange frequencies.
2. The crossover, and FR abnormalities which occurs, is away from the most sensitive part of the ear, a very general 2khz to 5khz range.
3. The doppler effect is minimized vs a crossover higher in frequency.
4. The old natural big box bass is simply superior imo. I have never heard a small box design that sounded
right, all the way down to the deepest bass.

ps. My speakers are 11 inches wide.
