Earthquake PN-4521

Very smart cabinet design and great build quality ; Excellent finish and elegant in appearance ; Excellent Musical and Theatrical sound ; Deep and clean bass response for a non powered tower ; They will handle tremendous power to handle large rooms

This isn't really a weakness but, the system isn't cheap - over $7,000...the towers are about $2700...while expensive, it would cost you much much more to get anything better. So, they are a great value comparatively ; Over all I can't think of any...
