- No box necessary!
- This means it's usually cheaper to design and implement
in your system
- Requires that a good seal be obtained between front and
rear of driver. In a car, this can be quite difficult and
may require the installer to remove trim panels to plug any
holes that would let energy "bleed through".
- The responsibility for damping cone motion rests solely
on the driver's suspension. As fatigue sets in, this becomes
a critical issue in infinite baffle set-ups.
- Less efficient in the sub-bass region than above
- Potentially more expensive drivers than good boxable
woofer - The suspension must be extremely hearty and
long-lasting to withstand high power applications.
