Sealed (Enclosure): Sometimes known as an Acoustic suspension type, the sealed enclosure is a simple design in which each woofer is mounted in a sealed, airtight box or compartment with a specific internal volume for precisely the woofer being used. The air contained within the box or compartment then acts as a spring that allows more control over the speaker's behavior. Great care must be taken in design, as too small a box will sound 'boomy,' while too large a box may have hardly any bass at all. This should be remembered when replacing a woofer in such an enclosure. Best results can be expected when using woofers with a QTS between .30 to .90. These speakers offer good control, low Distortion and high power handling.
