Specifically for Jason and others who may have an appreciation for music, speakers and quality sound.
These are a series of prototypes and a final design of a set of speakers that me and my father have been working on for the past 2 years or so. Don't have the specs of exactly what components they are or specs on the amp and pre-amp and deck but it powers the speakers all the way up to probably 140+ dB while remaining crystal clear and has an almost flat dB log curve.
As a bit of a background my dad used to be a dj back in his younger "cooler" days and started building speakers with his friend Adrian. My dad then took the accounting route while Adrian continued to build speakers, high end speakers and started a company called Tetra speakers. He has sold many sets of speakers (some of them go for as much as $40,000) to many big name music industry persons which you can see on the site.

Anyways our goal was to design a speaker that competed, well not only competed but surpassed the Tetra design in terms of sound quality. I firmly believe that we have
Pics of our work over the past 2 years:
prototype 1
Inside mold:
Faceplate initial design:
Concrete casing design:
Tweeters:
Mid-range:
Woofer:
Circuitry inside for the crossover points:
Assembling prototype 1:
And its in action ready for testing:
So after prototype 1 we figured it was a pretty good design. It sounded great, needed a bit more umphh from the lower frequencies but the mid to high sounded great. So we tested different size resonance tubes on both the top and bottom focal point holes and found a combination that worked phenominally.
Another thing that we didn't like was the fact that the speaker weighed in at just over 200lbs, we definitely had somewhere to go with this design for it to be practical.
Prototype 2
For this version we mixed in very small styrofoam balls with the concrete, not enough to ruin the sound rebound properties of the concrete and the structural strength but enough to make a difference in the weight of the actual speaker. We also changed the outer molding a bit more the take out some of the concrete on the back "legs"
The new outer mold being worked on:
The new speaker with the resonating tube in the bottom:
We still have this speaker in our basement but the finishing that we put on the outside wasn't the best. It just didn't look right for a high end speaker but it sounded just the way we wanted it to. Sooooooo we built another!!!
Final version
Not much else to say other than it looks and sounds just like a $40,000 set of speakers would
Thanks for reading and comments are appreciated, if people are really interested we can even arrange a time to come over with some friends and bring some beers and just chill, listen to the stereo and play some ping pong, darts, fooseball etc
