| Sealed Enclosure | |
| A type of loudspeaker enclosure in which the rear of the woofer fires into a tightly sealed chamber that is completely separate from the surrounding air space. Sealed boxes have a higher F3 than a vented box with the same woofer, but the low-end response rolls off at a shallower rate. Sealed boxes exhibit superior transient response and group delay characteristics than ported boxes. | |
