A Bright Shining Lie…Why ignoring an inconvenient truth is stifling system performance a blog from Roy Gregory

In my case the original panels were in excellent shape and did not need replacement. The focus of the restoration was with the deterioration of the foam around ribbons which causes the Buzz sound. And of course to retention the ribbons back factory specs.

The work was done by a gentleman in Florida name E. Pagan, who has decades of experience with all models of Apogees, including the Duetta II, Duetta Signature, Stages, Centaurus, Caliper 1 & Caliper Signature. His preference are the Caliper Signatures due to that to him they sound more magical in small rooms or medium rooms, and in large rooms will produce better execution on low bass frequencies due the lower bass notes needing the extra space.

He has restored Apogee’s for many years and feels that the best ribbon panels that you can have are the original Apogee panels with the matching crossovers as according to him, “each single Apogee speakers are tailored on the inductor coils of the crossovers to match each ribbon panel”.

My Caliper Signatures have all original ribbons and original crossovers and a silicone shore 8 on soft scale mix to regenerate the cushion that the foam lost after decades. Also all ribbons have been detoxified of magnetic particles and dust accumulated over the years on them inch by inch ( a lot of patience and time required to perform this job and not damage the ribbons).

Here is a picture of mine, the outer pair:

reviewers are human beings with their preferences /tastes and flaws just like anybody else

Amen !! I quit paying attention to them (and stopped buying the magazines) long ago. Not that I don't have respect for some of them, but my PREFERENCE and in person experience has far more effect on my personal buying habits (cars, audio gear, coffee makers, etc) than spec sheets, or subjective reviews (or for that matter, objective reviews).

What this hobby needs is more good music , not more reviewers.

Look at this forum alone some put themselves in the center of the whole operation
