Not only are you an avid audiophile, but also quite the wood craftsman. That is some serious work you did. Your wood shop is amazing. Congratulations on building an impressive subwoofer system.
Building Resonance Free Subwoofers
Rotator cuff surgery has left me with enough disability time to complete the picture diary of the construction of MS Tool and Woodcraft Model 4 passive subwoofers which many have asked for. Here it is https://imgur.com/a/dOTF3cS
Feel free to ask any questions. It will help fight off the boredom.

@rhg3 That is an understatement! Those woofers used a total of 230 shop hours. The going rate is $250/hour or $57,500!! Materials totalled $2300. Cost to manufacture $59,800. If they were direct marketed they would sell for $120,000. Most people only need a pair for $60,000 and you need a crossover and amps. Very few people will spend that much on passive subwoofers not to mention I have already told my friends with big systems that I am not making any more. Perhaps a manufacturer will see the post and find efficiencies to get the price down low enough to make them commercially viable. All I want is credit for the design. @rick_n @audioquest4life Thank you both. @blackbag20 They cross to the ESLs at 100 Hz 10th order. The first thing you notice is you can hear every bass note clearly. Many systems including my previous designs have one note bass. You hear bass but you can not make out the note or rather each note is the same. What you are hearing is cabinet resonance. Put on a set of headphones and you can hear each note clearly, that is what these subwoofers sound like. I put on Primus, My Name is Mudd which has an insane bass line and tell people to put their hand on one of the subs. They always then put their hand on the driver to make sure the sub is playing! Then, I get this look of amazement. |
