        I bought these Dayton Audio ND90-4 3-1/2" speakers and was shocked at how powerful and low they play. I got three resonances 48 Hz 60 Hz 90 Hz bass reflex tuning frequency 60. I really liked these speakers and with so small in size If they had a resonance of not 90, but at least 60, these would be super speakers https://photos.app.goo.gl/2K418U66kDx2bzyv7 Here I compared mine with JBL, Jbl 50 W, I have 20W on video, linear sound, all improvements...

        Very good for small speakers. I tried several box volumes and passive radiators waight but i can’t able to reproduce deep bass below 80/90 hz. Good sound but needs a sub reinforcement for my tastes.
