That's how South Korea kept their death toll at 301 and Japan at 1,011. You'd think that fines wouldn't be necessary, that the promise of staying alive... -
You can avoid it and cross very close to Fs with a high enough filter order. Neville Thiele's preference was for fifth order. He felt the additional component...Leave a comment:

ULF frequencies are inaudible to elephants as well. They sense those vibrations through their feet. https://www.sfgate.com/science/artic...et-2593114...Leave a comment:

True. If the measured response indicates a need to lower the Le you can always strip wire, which is better than having to add more should you do so and...Leave a comment:

Wow. I searched what's happening Down Under, and it seems you've got the same screwballs as we do mucking up the works. It's a shame, because it seems...Leave a comment:

The effects of length, taper, throat and mouth size can all be modeled in HornResp. It also can model polar response but only with a round mouth. It does...Leave a comment:

There's no need to try a woofer to see how sensitive it is or to see its frequency response in various cab types, speaker modeling software will tell...Leave a comment:

I measure with 1/6 octave smoothing. That's as much resolution as you can hear, so there's no point driving yourself to distraction with so many peaks...Leave a comment:

Two ports in the same chamber function as one port. You must have two chambers. WinISD 0.7 is freeware.Leave a comment:

The Fs isn't the reason for the high F3, that's primarily the result of the low Qes....Leave a comment:

It seems the main difference is the surround, rubber half-roll on the HT versus cloth accordion on the Pro, which drops Fs a bit.Leave a comment:

Model it and you'll see. If you simulate the voice coil inductance F3 drops to 55Hz, but response below 50Hz remains the same, as the shift in F3 is the...Leave a comment:

That's at 2 watts. At 1 watt it's 92.8. That's still respectable, but high sensitivity is usually the result of low Qes, which also results...Leave a comment:

It models fairly well in 8 cu ft ported with 27Hz tuning, but not spectacularly so. In 4 cu ft sealed it has enough xmax to run with a Linkwitz transform,...Leave a comment:

It can't hurt, but no need to overdo it with those curved surfaces. Maybe just on the flatter surfaces.Leave a comment:

It's an inherent problem at very close listening distances. It's why you seldom see dual woofers used in studio nearfield monitors, which typically are...Leave a comment:

In blind testing EQ'd for identical response, at identical levels, and not driven past linear limits, you can't tell the difference between sealed and...Leave a comment:

Most of you weren't around to remember this, but in the early 1970s acoustic suspension dominated the speaker market, to the tune of a 90% market share....Leave a comment:
