Based on Paul Carmody's Sprite and Murphy's corner line array, I've developed a little "thing" about the Dayton ND90-8. I've been toying with the idea of building a pair of computer speakers out of them in a transmission line. A single full range driver with Paul's filter. Simple and quick is the idea. This simple little calculator http://www.mh-audio.nl/Calculators/TML.html would probably do the trick, but if anyone else has access to Martin King's software and would like to embellish the concept, well, that's what this thread is for! Simple, quick, cheap. Not fantastic SPLs, but F3 in high 40Hz - low 50 Hz range should be achievable. Peeking over a computer monitor is the idea. The driver is here: https://www.parts-express.com/Dayton...iver-8-290-210
I hope someone is interested in playing this little thought exercise. If not I'll build the simple calculator version. Either way, it should be fun!
