If it was me to do so I'd
- buy from company directly, if possible, otherwise certified seller
- burn-in, run-in, whatever-in protocol 24 h (and document it, just for shure)
- klippel it (or use some other decent device for measurement)
- disassamble it and document every single part I can find
- evaluate if redesigning crossover, BR-design, enclosure-damping etc. could do profit
- publish measurements of original design
(chuckle, if evaluation brought up siginificant inprovement, and wait)
- if then complaints arise, publish own 'enhancement'
