David Mellor’s description of his first two speaker builds is priceless…
He was building them for use with his band.
1st Built the boxes just big enough to fit the drivers… so the speakers would fit in his car.
2nd his car was now ahatch back & built the cabinets bigger, he’d carry one speaker at a time… but reversed the polarity… didn’t realize it… thought it was a horrible build… sold it to a man that wanted a pair… so built a match… but it sounded great….
Anyway, he goes through the build levels:
Buy a kit with a flat pack…
Buy a kit, but build the cabinet…
Buy a kit, but assemble the cross over…
Pick your drivers & match with a prebuilt crossover…
Finally get some design software & design speaker & crossover yourself…
I personally have built kits with or without flat packs … or bought drivers then found matching prebuilt crossover…
& every one I built was “the best speaker in the world”….
