This article will describe the fruits of my efforts to build a moderate sized speaker which might be moderately above average in performance for a basic two-way system. I desired a speaker like this both for my own use in secondary systems, and to fill a need for some friends, who desired fairly full range response (i.e., “it’s gotta have good bass”). Also, though I have access to a good wood shop, many potential DIY enthusiasts may not, so I hoped to use a modified...31 December 2024, 17:31 Tuesday -
Sometimes we find freeware that meets or exceeds commercial packages and I thought it would be good to start a list of peoples favorite freeware (can't be shareware...nor can it be shareware + "a crack I found on KazaA").
So here we go:

Minimum phase for a speaker can be described of the phase of the frequency response of the speaker at it’s acoustic centre, or the phase without any excess phase or “time of flight” included. It can be calculated from the speaker’s frequency response using Hilbert-bode transform, or HBT. When comparing multiple minimum phase responses, we can say that the responses occur at the same point in space, ie. there is no physical distance between them. When measuring speakers and processing the...26 December 2022, 14:27 Monday -
Gregg Loewen of Lion Audio Video calibrated my set this week.
I purchased the set from Circuit City 4 months ago and after running Video Essentials I was very happy with the picture. DVD's looked great and DirecTV was pretty good, some channels looked good and some looked bad. I planned... -
With a simple jig, loudspeaker impedance and T/S parameters can be easily measured with LIMP. The same jig may also be used to measure component value for resistors, capacitors, and inductors, as well as measure transfer functions of passive and active filters.
The setup is quite simple, the following diagram is taken from the LIMP manual:
