it's real loud in the upper bass region (100). you can make 1 12 hit 127db in free air (that's loud). but they don't go that low in frequency. the cut off is around 70- 90 hertz on mosts. it will go lower in a corner, but not much. if you face it down to the ground with legs built on it, it will go a lot lower and pound
Soundmaster2.0 what you made was a speaker stand/ mount, it has no inherent properties of a sealed, ported or bandpass box ...due to your use of USPS tape for the sides.
It's cool. my first stereo was like that (I was 12). because my dad had lot of trucks people would sometime have have him hual away their furniture and stuff. A lady threw away her stereo so I took the horns, tweeter and woofers out of the humungous stereo and I went to the store and got some cardboard boxes and cut holes in them. I put the speakers in them and hook it up to my boom box.
