2 identical pair of speakers side by side, 1 with drivers that had been playing 7/25 for 6osh days and a 2nd pair with drivers freah out of th ebox. No delay between one pair & the other. Dramatic differences.

The OP's report would have more credibility if another speaker was used as a reference before/after. Still, a single individual switching components is not a very good test. I know this from personal experience.

It took 10 minutes to swap out the drivers. The change was immediately apparent. I didn't create this thread frivolously. Your logic makes no sense. I have been listening to the same system for 14 months straight. I know what it sounded like. 10 minutes later, it sounded very different. I had to turn my sub on. I had to dial my tone controls.

End of story.

When you swap nothing but the drivers in a 10 minute interval, there is no acclimation involved. The sound is dramatically different.

Like many of you around here, I spend hours a day (many hours) listening to my system. I change nothing. It always sounds the same. I changed the drivers out for new ones and bam! Different! So much so that my wife and one daughter commented on it. After all, I had to convince the wife to let me buy them in the first place...

Me: "Ummm, ya... I know, I just have to dial in the tone controls..."

Perhaps I am missing your point?

No way. I am convinced. That's good enough for me. I just wanted to report it, not prove it.

Apparently Dave and I can hear better than the rest of you.

True. However, if you were here at the time (and you are not tone deaf) you would have experienced the same thing. I'd put a thousand bucks on it.

BTW, it seems simple enough to me.:

Fs on the EL70 is rated at 64hz. The "old" drivers were likely reaching that low.

Fs on the 4 new ones were measured by Dave to be closer to 70hz.

Include the fact that this is a MLTL design, recognizing the fact that such designs rely heavily on lower Fs to really start to dig deep. That 8hz delta would translate to significant bass loss in an MLTL. That's what I am hearing, and I have no doubt I will get it all back, in time.

Not asking you to prove it - it's a great opportunity to get some data. I hear differences between a fresh driver and broken in driver BTW.

Breakin is real, for you.

What kind of replies did you expect?
I guess you dont need to contribute to this topic anymore.
Thanx for reporting.
