Tkacik) Organization: EE Dept., U of Virginia, Charlottesville Lines: 15 Summary: Does anyone know how the speaker configuration (vented, sealed, etc.) affects a woofers sensitivity? Acoustic suspension speakers are known for being less efficient than bass reflex speakers :-) Is this because IT IS an acoustic suspension speaker, or is it because the drivers used are less efficient than drivers used in vented speakers? Why would this be the case? I have also seen a statement which helps a builder decide wether a particular woffer will work better in a sealed or vented cabinet. If fs/Qe (resonence frequency divided by electrical Q) > 100 use a vented speaker. If it is less than 100 use a sealed speaker. Does anyone know how to decide if a driver will work in a TL or horn?
