Cornwall IV and break in

Recommended Posts

Lots of good points, including things I hadn't thought about before, like @joessportster comment about needing to start the breakin process all over if a speaker hasn't been used in a long time. But, I'm still skeptical about breaking in. Speakers are make from components, which are designed to specifications, then tested after manufacture to ensure they meet those specs. Since that is measurable, is there anyone doing before and after measurements on drivers after xx number of hours, to see if those numbers have changed? Is that something that PWK would have thought of and documented during his long career?

I'm 99% sure that PWK would have whipped out his "BULLSHIT" button since Horn Loaded Woofers hardly move to produce loud sounds. So pushing their excursion limit with any kind of "break in" would have very little effect on the actual output of the speaker, so the real break in happens with the OWNER!!!

I Agree with Claude. Think of the bass speakers as a horn driver just like the mid and tweeter driver. Horn drivers move very little and depend on the horn to amplify the sound. Since horn drivers move very little the sound is naturally more clean, equating to less distortion. I doubt it takes very much breakin with a Klipsch horn loaded bass driver. Bass speakers in conventional speakers are the ones that require a few hours to limber up being that they have to move so much more to produce bass notes. IMHO

That's all well and good until you remember that the Cornwall is NOT a horn loaded bass speaker............

You are correct. Only responded to Claude's statement without looking at the topic of Cornwall's. They do need some time to limber up being a conventional bass speaker. I stand corrected.

No need to stand corrected. Since Cornwalls used the same woofer as the Khorn for years and years, and the Cornwall box was designed by PWK around that same driver, I just wanted to communicate the difference between the two. So break in is not always required for the same driver depending on it's excursion demands in actual use. I'm still not totally convinced about break in other than when drivers are brand new.

All I have to say on the matter is that three weeks later the CW IVs sound very different than they did in the beginning.

Yes indeed. This means YOU and the speakers are fully broken in to each other! LOL.
