The primary benefit to multiple midbasses is being able to use two smaller drivers that have at least the same, if not more, displacement than one larger...Leave a comment:

For home theater use, sure, but in a vehicle F3 lower than 50Hz is counterproductive due to cabin gain. Cabin gain allows using a smaller sealed enclosure,...Leave a comment:

I'd say that 300Hz is unnecessarily low. I don't see any problem with 800Hz, which would greatly expand the choices for the mid driver.Leave a comment:

Fb is usually midway between the two major peaks, in this case about 30Hz. The various peaks and valleys in the chart can probably be attributed to insufficient...Leave a comment:

It indicates the front chamber is too big. If there's an error most often made when calculating a bandpass it's having too much sensitivity at the lower...Leave a comment:

December 7, 1941 is an example. Why did the Japanese attack us? Not for the reasons most think. It was because they thought the US was trying to put them...Leave a comment:

Those sold in the US and Canada are made in Kentucky, from components that are primarily sourced from Asia. Their factory in China services mainly OEM...Leave a comment:

No need. Its content was one of the things we discussed when I met him. He did not say that efficiency and distortion were inversely proportional, he...Leave a comment:

I doubt that all speaker magnets are made in Asia, but I wouldn't be surprised to find out that 95% are. The same applies to frames, cones, spiders, voice...Leave a comment:

1% distortion is irrelevant. That's -40dB. It may seem high relatively speaking, since 0.1% and lower is common for amps, but that's because it's so easy...Leave a comment:

They are huge. I use a Table Tuba myself. The THT came about at the request of Adire Audio, back when it was run by Dan Wiggins, who wanted a folded horn...Leave a comment:

One major advantage to a horn loaded speaker versus direct radiating is negligible distortion. This has been well documented going back to Paul Klipsch....Leave a comment:

That rule of thumb is incorrect. My Tuba HT, 28Hz F3, has a mouth area of 320 square inches, with a circumference of 74 inches. What the mouth area limits...Leave a comment:

+1. The low Q gives high sensitivity but poor bass response. That's fine when used with subs to handle below 80Hz or so, which would have been the design...Leave a comment:

The effect is also exacerbated by how many devices your system has, as each adds its own bit of noise. Back when I had a TV with analog audio outs I had...Leave a comment:

Running the power cord back to the AVR power strip doesn't help. Ground loop noise isn't caused by not having a common AC ground for the components, it's...Leave a comment:
