    First time DIY Subwoofer AV12 Tube - Help!

    I will have to see if I have the space for 2X 32" tubes with 48" ports sticking out of them. It didn't seem right before having the port come close to the back of the driver. I can open word files. Thanks in advance for sending the graph. I tried reading some of MK's stuff last night...

    Thanks again! This is great! You are right, who cares what they look like as long as they sound great. I will just convince my wife that funny tubes always stick out of the good subwoofers. I calculate that I can reduce the 92L tube (15.5" ID) to around 34.75" long with 24" of the port inside...

    Actually, I get a longer tube with 6 inches. 2 ports 3.875 inches in diameter have less volume than one 6 inch tube so the 6 inch one would need to be longer, right? Anyway, I have the 3.875 sitting here for free so there would need to be a good reason not to use it. I was hoping that it...

    First time DIY Subwoofer AV12 Tube - Help!

    I am planning on making 2 SVS type subwoofers (Sonotube with driver on one side and ports on the other) using Strike's TC Sounds AV12 driver. I plan to lay the subs on their sides behind the couch and drive them with a Sampson S1000 amp. My goal is to be able to produce sound at near...
