Ok this is my question. <BR>Why do tower speakers have cotton in them, and how come there are no vent holes? <BR> <BR>I thought speakers needed to breath? <BR> <BR>Thanks for any info <BR>David

The cotton is actually polyester fiber-fill. It is there to make the speaker think the enclosure is bigger than it really is. It also helps with the acoustical resonance. The only time you want a vent hole is if it is a exact size and length to "tune" the enclosure for a better bass response. Otherwise it is best to have a fully sealed chamber.

Thanks
