PROS:
Sound great.
Affordable entry to diy speakers.
Can be "upgraded". I turned my tritrix speakers into the
Dayton Classic WMTMW for only an extra couple hundred bucks for the pair. Just needed 4 Dayton 8 inch speakers and some more new/replacement crossover parts.
CONS:
It takes a bit of time to build them. It takes even more time to build them well and make them look good.
May require tool purchases that would bump up price.
In my opinion, totally worth it.
