Sealed or Ported Sub? What should I do?

It seems like this would be an easy decision. Just pick the box that best fits your design goal. But did you know that there are two differing rules of thumbs on what type of box a driver would best be utilized in? Seriously. One of them uses the QTS of the driver, while the other uses a formula called Efficiency Bandwidth Product. Let's talk about both for a minute.

HOW TO BUILD $3,500 SPEAKERS FOR $400 – KLIPSCH KL-650 COPY

123Toid Leave a comment

The Klipsch KL-650 THX Ultra II were iconic in the Home Theater Industry. It was one of the first times I remember that you could affordably buy speakers that were truly designed for a small movie theater, for your own home theater. However, when I say affordably, they still cost around $$3500 for a pair! And for the entire system...a cool $13,000! And although, for movie theater speakers, that isn't crazy, it is still a lot more than I want to spend on my Home Theater. And truthfully, I think that is the same as most other people. SO why not build some, for a lot cheaper.

The Best Amplifier Under $150? SMSL SA300

123Toid 1 Comment

The SMSL SA300 is loaded with features and customization. Could this be the best amplifier under $150? The amplifier itself came with a few pamphlets and a user manual. Although the user manual looks small, it was quite thorough on the operation of the amplifier and remote control. The box also contained a USB cord for the DAC, a massive power supply that is capable of outputting 162 watts, a Bluetooth antenna and a remote control.
