Rel makes some of the best woofers on the market known for speed, accuracy and integration.
I don’t disagree that they make well performing subs, just that there are equally performing subs for cheaper
Salk makes decent speakers using other peoples drivers. Rel or JL Audio design from scratch everything, this generally means a better performing product.
Disagree. It may mean their costs are lower as they don’t need a middle-man, but that doesn’t mean they make better sounding drivers than RAAL, SEAS, Scanspeak, etc. if the drivers are well performing, the crossover is well designed, the cabinet is inert, etc. who cares if the drivers are a third party, as long as the end result is good. There have been some “showdowns” between different equally priced speakers that included a Salk speaker, and everyone I found ended up saying the Salk sounded the best, including ones that were blind testing. I’m not saying they make the absolute best for the price hands down, but the certainly are up there.
for music servo woofers can often times be considered slow.
Untrue, at least for Rythmik (who Salk uses). Look up measurements, their subs usually have impulse response that is fast and clean, group delay is below 1 cycle, well controlled decay, etc. They are very tight and fast subs, even their ported models.
