Bass trap is 18" deep, 36" high, 8' wide. Covered on 3 sides by speaker grill cloth on wood frames. The rear is covered by screen.
It's packed with R-13 pink fluffy fiberglass. This will do the work of numerous hanging traps. I used it against a wall.
It's well-built enough that 2 adults can stand on it. $150 for the bass trap. These will require a pickup, van or truck.
Not that heavy, but bulky enough to require a larger vehicle.
Both devices are clean, no smoke, no animal stink.
