The Isabel Signature is newest speaker in the EgglestonWorks line. The Isabel Signature is a floor-standing 2-way speaker with respectable low frequency response. Many people have said that the bass response of the Isabel is surprisingly impressive for a speaker with a single 6" driver.
The Isabel Signature is no entry-level speaker, but more a model for smaller rooms. However, this speaker is still capable of presenting a large soundstage with accuracy and airiness.
