What do you do to "Break in" new woofers

[Retriever 1,128]

They just sound so tight at first allways seems to take some break in before they sound right.

Thought about taking my oscillator to about 15 hz and drive the amp to about 100  watts to speed the process. Any Ideas?

Well darn returned to its original values, however one sample the FO lowered by 5 Hz this is enough of a change to affect port tuning of the enclosure. the speakers are close to the original protypes For Qts and VAS, however the Free air resonance is higher 30 hz vrs 26 hz of the originals.

The problem I have with the GR research link is that he doesn't follow up on measurements days/weeks later, just hours; there is a change in T/S parameters short term, but they eventually settle back

I should point out that these are my "half size" prototypes built years ago to test the math of the design, performed so well I went on to the full sized cabinets.

Yep, I love the guys speaker design, but he has some thinking I just dont share.

Hes a big promoter of cables and ICs, and me not so much....to each his own. 

 

Just thought I'd  post another view......
