    Actually, not really. The bass is great with the drivers half towards the floor.

    Ive always been surprised how the mods sound free air, when you leave the room, you can hardly tell they are free air versus in an enclosure. The bass is not as forceful or the impact but it is there.

    They wont fit inside :) Some people also feel external crossovers sound better since they are not exposed to much vibration... ymmv
