Extremely clean for the price i was so surprised how loud they play🔉🔊🎶

Auto Stereo
Great performance

I have to say this is one of the best pro mid on the market and the price definitely does not reflect the quality and performance. Solid midrange with great low end. I used a sound processor with a band pass cross over the filter out any extremely low frequency and clean up the higher. Very efficient speaker, plenty of volume with 100 watts rms per speaker. Great choice for building a motorcycle system.
