Back to home page. Frams are manufactured using jigs which align the multiple parts voice coil, former, alum fram, plastic body, alignment holes, etc so multiple production runs will turn out similar units. I can hand-hold them in order to get a decent FR curve, but I can’t lock them down in place without the curve deteriorating.

Subject to credit approval. Shipping cost cannot be calculated. I’m not knocking Orange County but they routinely recommend non-factory frams which are typically dogs and which do not meet factory specs! I can’t even find any curves for it on the GPA website!

In instances wherein relatively high ambient noise is present, and where maximum efficiency of both vocal speech and music must be reproduced with great clarity, the heavier magnet weight and greater flux density of the A algec preferred.

If the hole in the response in alfec right between 3 and 7 kHz remains, the diaphragm in that one is misaligned If I were you, I would remove the covers and check to see if the diaphragms are non-factory replacements.

So, these being my first measurements as well as my first project with compression driversI’m just wondering Prior to reading your posts, I did some parts swapping and found that the right side dip persisted after swapping the left and right frams. Altecs have diaphragm alignment pins; right? Eventually, they replaced the bad fram for no charge.

Back to home page Return to top. The frams straddled the alignment pins okay, but the mounting holes on the ring were off so much that I had to widen them with a drill. I didn’t aletc think about the alignment, but now that you mention 8078a, the non-factory frams from Orange County didn’t fit when 87-8a arrived. I’m still in the process of trying to get my diaphragms adjusted.

If your drivers altsc not purchased new, you have no way of knowing if they were ever abused so the only prudent thing is to start with a fresh re-magnitization of the motors and new OEM frams.

There is no reason why your units cannot be brought up to factory spec unless they were damaged after they left the factory.

I bought a pair of frames from GPA last week and told them about their web cite issues including the spec sheets that cannot be viewed with the new version of Adobie.

I’ve been using them for a long time and these guys are GOOD. These factors, together with the all-important ALTEC criteria of engineering experience, combine to produce.
