While I agree that proper testing procedures are required for definitive proof of audible differences when dealing with the same class of speakers, there are situations where there is such an Extreme difference in quality as to safely make an immediate judgment of preference.

For instance, put a small cube speaker from a cheap HTiB setup up against an M80 grade floor stander??? An extreme example to be sure. True, in this case we are dealing with a modification to just one component without changing anything else like the driver, cabinet, etc. Here there is indeed argument for controlled testing.

However, just to be the devil's advocate..... What if Jake adds in these new crossovers and they change the sound in such a large degree that it is simply unmistakable. Unlikely but perhaps the new crossovers are tuned sooo way off for this particular speaker configuration that it turns them into the tinny sounding equivalent of a tiny cube speaker. Or, to be fair to Ninja, maybe it goes the other way around. Although an improvement to that scale is even more unlikely due to the laws of diminishing returns on a speaker of this caliber.

So no disagreement on the necessity of controlled testing for most situations but lets not say his experiment has no value just yet. I for one, look forward to his comments as he is the only one investing the time and money to do at least this much.

With great power comes Awesome irresponsibility.
