After experimenting with various combos of crossover values, although the MK I cheapowave using the Pyle PDS221 compression driver sounded OK.. the high end was never really impressing me.
Note: this post continues on from cheapowave MK I postwhich documents building the cabinets etc
After reviewing the Econowave thread on Audiokarma yet again I ordered in a Selenium D220Ti-8 from Parts Express in the USA. The shipping cost almost as much as the drivers themselves.. but although I could probably find a more than acceptable replacement from the P.Audio drivers from Cannon Online, I decided to go with a combination that already has shown so many good results for others, plus the hard yards on the crossover circuit has already been done by people with way more expertise than myself.
The Selenium drivers arrived, and the immediate impression is that they are bigger then the Pyles.
