Skar Audio SK150HZBB PR Frequency Filters Review

These filters really make a difference in the sound quality of your car's audio system! The installation was quick and easy, and the difference in the sound quality was immediately noticeable. The filters are compact and well DESIGNED, and they are a great addition to any car audio system. The only downside is that they are a bit pricey but the quality and performance make it worth the investment..

These filters make a noticeable difference in the quality of sound in my car. AS my tests showed they filtered out the background noise and produced crystal clear sound .The installation was a breeze, and the compact size meant that they didn't take up much space in my car. However, they are a bit pricey compared to other filters on the market. Overall, these filters are a great investment for anyone looking to improve their car's audio electronics..

I bought 2 sets of 150Hz door speakers. I have a separate sub box so I wanted to cut out some of the bass playing through the doors. They work as advertised but are much "bulky" than other brands. I barely had enough room in the "speaker column" to accommodate them. If space is tight, consider another brand. Also, they (and every other brand) don't completely eliminate bass. Rather, they weaken the bass. This means that they reduce the bass by 6 dB. This is how condenser crossovers work.
