Initial Listening and Gradual Refinement Having already written the basic crossover software, and after a day’s furious woodworking and wiring up, the system worked! I set the relative driver levels using the amp volume controls, doing this by ear, matching the levels at the crossover frequencies. So at this stage I could listen to CDs […]

Software I have some experience with real time programming and DSP so I decided to write the crossover software myself. Firstly I established that with a suitable software library I could receive audio from a sound card on a sample-by-sample basis, and also send multiple channels of output to the sound card, all locked together […]
Electronics This was fairly straightforward: I would need a Windows PC, a multi-channel sound card and three stereo amps. The PC was a several-years-old Dell that I knew was going to be pretty much silent, running Windows XP. I struck lucky with the sound card, finding that a Creative X-Fi is very well behaved with […]
Woodwork I used the program WinISD to calculate the ideal size of sealed enclosure for the bass drivers. Ideally it would be 120 litres. Quite big! I managed to find a pair of 1969 Goodmans Magisters going locally for £20, which have about 90 litres internally. Luckily they weren’t in great condition, so when I […]
Further work I have been listening to these speakers for almost a year, and have hardly made any modifications in that time. I sold off my previous audio gear (except for the vintage stuff) with no regret whatsoever. It is tempting to go four-way just to see if it could sound even better, and I […]
Solid State and Active are Clean I don’t think it is too controversial to claim that solid state amplification suffers less from distortion than valve, can have higher reserves of power, lower output impedance, flatter frequency response and so on. Nor is it controversial to claim that active speakers <a href=”http://en.wikipedia.org/wiki/Powered_speakers”>distort less</a> than passive systems, […]
The Result, and Interpretation Obviously I don’t expect to convince you that my speakers are ‘high end’, but they are! All types of recording sound better than I have heard before (outside, presumably, of the active Backes and Mullers mentioned earlier!), but where the system excels in particular is in playing back uncompressed large scale […]
