So, my brother brought over over 4 blown Cerwin-Vega Pro Stax PSX-153 speakers from the club for me to take a look at them.
Three of speakers had original crossovers, all of which were damaged and burnt, likely due to excessive power being applied to them (the PSX-153 is rated at 600 watts PEAK)
One of the speakers was fitted with a generic, and likely very unsuitable, crossover. The original crossover likely suffered the fate of the three mentioned above.
We took the speakers apart, and we were able to salvage three woofers, three midrange drivers and three tweeters from the four speakers. The remaining drivers were blown.
New crossovers can apparently be purchased online for the PSX-153. Apparently the original crossover had a “flaw” and the new ones have a “daughterboard”, which is basically a mini crossover that connects between the main board and the midrange. The new crossovers can be purchased online from www.speakerrepair.com for about $150 each. Three of the speakers can be returned to service almost immediately if three of these crossovers are purchased and used to replace the damaged ones.
It may likely be possible however to manually build replacement crossovers using components from Madisound or Parts Express. Of course the schematic for the original crossover will have to be sourced (or worked out from the burnt ones).
Of the blown speakers, replacement midrange (MR-65A) and replacement diaphragm for the tweeter (CD44C) can be sourced from www.speakerrepair.com for about $70 and $60 respectively. Of course a new crossover will be needed too, bringing the total to $280. Considering that the woofer also needs to be replaced, it may be best to simply buy a new speaker (or two, considering one of the other PSX-153 speakers left at the club is basically an empty shell). Alternatively, I'm thinking that the two empty shells can be used to build two new speakers using parts from Parts Express. I'm interested in doing this, particularly if can be done and produce similar performance to the originals at a fairly cheap cost. That said, does any one have any plans or suggestions for a decent two-way or three-way that I can fit into the shell of a PSX-153?
