Just looking for some reactions to these speakers, specifically the 5 1/4" DKE-113 for the rear of the w123. (And the 110's for the front.) There are some posts mentioning that people have installed them, but I'm looking for folks who have some mileage with the speakers. Any bass response at all? Onlinecarstereo.com has them for $49.99 right now. Trying to decide between them and a pair of Polks that are about $20 more. Thanks for your responses.

Joe
