The problem with this subwoofer is the exhaust, which is located at the front. At high volume, the sound of the air "whistling" is noticeable. For its 50W and price, it is of good quality for room use.

I had purchased the Presonus Eris E3.5. I don't make music, but I wanted the music I listen to be crystal clear. The Eris 3.5 achieves this in the mid and high frequencies at a very good level. However, what they were missing was the bass, so that the sound could be richer. This sub does exactly what it should, it takes care of the low frequencies and leaves the mid-high frequencies for the Eris 3.5. In a way, it "relaxes" them, resulting in the sound after purchasing this sub to be louder, richer, with punchy, clean bass and not like the dirty bass (boom-boom) you hear from every Honda Civic passing by your neighborhood (no offense). In combination with the Focusrite Scarlett Solo sound card, at the moment the music is the best I have ever heard. Because everything together is expensive for some, I would advise buying them piece by piece, it really is worth the investment for those who are crazy about music and want to exceed the quality of classic commercial speakers.

Excellent sub, it elevated the eris 5 to new heights. I have chosen it mainly for listening when I am sitting at the office. The best 2.1 system you can create for this amount of money.
