Review on Skar Audio SK150HZBB PR Frequency Filters by Ayush Bonuccelli

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.
