Customer comments: (POLK SDA SRS)Installed the crossovers over the weekend. Speakers sound FANTASTIC! You restored the upper range frequency response. Thank you for a job well done!The speakers now sound incredible!E.D. another customer..... (POLK SDA SRS)"Hi, finally got the crossovers installed.... they sounded very very good out of the box... after about 20 Hours run-in, everything is opening up nicely. The new crossovers are a huge improvement over stock... massive soundstage, much better clarity and instrument separation and the bass is tighter. Most of all, everything blends together in a supremely musical way. With a good vinyl recording, the results are simply stunning!" C.G. another customer..... "They connected easily enough. The difference is night and day. They settled in really fast and the first thing we noticed was the transient detail. The speakers don’t sound lazy anymore. The transients are tight and impactful. The bass is presented beautifully- we were able to pull our alignment filter. There is more space.These are the speakers they should have been all along. Thank you for taking care of us.P.G. another customer........“Perfect!! Thanks again. Sounds great !!” (J.D.)
