That's right out of the Spammers Handbook, along with resurrecting zombie threads. -
There's got to be something in the Spammer's Handbook about digging up zombie threads for their initial 'testing the waters' posts. First posts that are...Leave a comment:

Narrow slots cause more chuffing and they also reduce the effective port area, lowering tuning. There is a zone in the port where there's high friction...Leave a comment:

I should have said 1.3ms. Sound travels at about 1125 feet per second, so one usually does an in the head quick calc as 1ms per foot. In any event you...Leave a comment:

I doubt you can hear a 16ms delay at 160Hz. Maybe at 320Hz.Leave a comment:

I rout first, then veneer. After veneering you rout again to trim it to the holes, using a special bit made for the purpose.Leave a comment:

When you try to force the design, rather than let the design determine the size of the box, there are going to be unavoidable compromises. For a no compromise...Leave a comment:

Reality check: you'll never put peak power into it. You're not likely to even put the full 300 watts RMS into it. It's reasonable to assume that you'll...Leave a comment:

Box Fb goes down as box volume goes up. Box Fb goes up as port area goes up. It's as simple as that....Leave a comment:

Again, I don't know how it works. But knowing how radar and sonar works I can see potential parallels, so I wouldn't discount it out of hand.Leave a comment:

Look at the port velocity at full power in your software model. You'd want it no higher than 20 meters/second.Leave a comment:

Your correct, ka is directivity in the low frequencies, In the high frequencies it affects the high frequency corner, which goes down by a factor of 0.7...Leave a comment:

Assuming both are rated 98dB at one watt that's 2 volts for the 4 ohm, 4 volts for the 16 ohm. With the same voltage signal the 4 ohm will be 6dB louder...Leave a comment:
