低音喇叭:Tang Band Speaker W5-1138SMF
I brought this project to InDIYana 2013, but never put any info out there about it. A thread a few days ago asking for a small sub prompted me to get myself in gear and post the plans.
I designed the sub around this amp, although obviously any sub plate amp will work (depending on how creative you want to get mounting it to the somewhat small enclosure). Is this amp truly 68 Watts? Probably not, however it has the neat bonus of allowing you to add bookshelf speakers to create a 2.1 setup.
The only other things you need to do this project are:
- TB W5-1138SMF (great little workhorse)
- 2 of these vents, glued end-to-end
- 1/2″ plywood or MDF.
外壳的大约体积约为 7 升，它应该达到 35 Hz 的 F3。我没有最大 SPL 的确切数字，但理论上它应该能够在放大器耗尽蒸汽之前达到 98 dB。端口直径可能是这里最薄弱的环节，如果再用力推动，可能会非常糟糕。那个司机，它只是走来走去；这就是它的本意。
The approximate volume of the enclosure is around 7 Liters, and it should reach an F3 of 35 Hz. I don’t have an exact number for the max SPL, but in theory it should be able to get to 98 dB before the amp runs out of steam. The port diameter may be the weakest link here, and would probably chuff pretty bad if pushed any harder. That driver, it just goes and goes; this is the kind of thing it was meant to do.

关于导向管长度的一些说明:
9″ 模型稍微好一点，但是……我认为 Paul 说 9″ 是总长度（包括 2 个圆角端）。如果你用 1.5 英寸的 PVC 制作自己的通风口（直的 – 这可能会导致咯咯笑），它可能只有 8 英寸长。无论如何，如果你买了 2 个这样的管子，并按照保罗的指示使用它们，一切都会好起来的。
