I had success with a TL design drawn by the people on this board with Martin King's mathcad sheets. Very pleased with the enclosure, gives a different sound to any other design I've heard and the bass keeps going lower and lower without suddenly dissapearing (its a small sub design).
Those worksheets are available but perhaps someone would model it if you told us the model of the driver. Usually a high Qms of around 3-6, a low Qes around 0.3-0.4 and a low Qts of about 0.3-0.4 work well combined with a relatively low resonance frequency (30Hz would be good). If your parameters are way outside this you may not be met with such success.
