Would suggest Hertz or DLS .. Polk is way too bright even with a silk dome tweeter . DLS and Hertz have paper cones and Polk has plastic cones . The SQ is definitely better with paper cones . For Hertz you can check out Maruti dealerships as they sell Hertz and are cheaper than the retail shops . The Energy series are good from Hertz . Please do not go for deici or lower versions . they have a plastic dome tweeter .
Are they from the same price range?
