If It Ain't Broke, Don't Fix It


Exhibit A for: If It Ain't Broke, Don't Fix It

Object Lesson: If It Ain't Broke, Don't Say It's Broke and Damage the Good Reputation of A Well Regarded Company So You Can Make Money on Gullible Viewers

This is a critical review by Audio Science Review regarding a speaker crossover upgrade kit sold by GR Research for the Ascend Sierra-2EX V2 speakers. The video features a neutral A/B comparison and argues, with evidence, that the measurement methodology was flawed, that the performance was made worse, that false concerns about impedance are asserted, and overall there is no objective evidence of improvement and that the Ascend Sierra-2EX V2 is already a well-engineered speaker that does not require aftermarket modifications.

Taking a general pot-shot at ASR is for me a way of life...Like going to used record stores...

Daniel von Recklinghausen, the renowned audio engineer at EAD and KLH is famous for this old chestnut: “If it measures good and sounds bad, — it is bad. If it sounds good and measures bad, — you've measured the wrong thing.”Hard to argue with the man's logic.

If it sounds good and measures bad, — you've measured the wrong thing.

Bright speakers sound good at first and measure bad. So, it seems that the question is, "sounds good over X amount of time"

@hilde45 If we are judging business' reputation based on measured performance specs only and how well those specs correlate, why are we calling out Danny for not measuring distortion specs without calling out Dave for phase response errors and impedance mismatch in drivers? Dave has a klippel, wouldn't they measure for that? Heck, even a umik1 and REW could do it. I could understand big mfg turning a blind eye to that on their base level speakers, but seems to me there was some engineering "good enough" and some cost analysis to fit a market point at Ascend. Time and phase alignment is one understated key point to set great speakers apart from the good ones while driver quality, crossover components and cabinet construction being the others usually get more attention.
