Home High Efficiency Speaker Asylum

Need speakers that can rock with just one watt? You found da place.

RE: found problem with 808-8A frequency response ...

I removed the back cover and diaphragm so I could shine a light thru the phase plug and see if the bug screen needed cleaning.

Bill at GPA suggested removing the bug screen, but I have read that it can collapse the magnetic field of the driver, so the bug screens were left alone.

I was not sure how to properly take the driver apart any further without damaging it, so that was as far as I went with the process.


There is a local prosound/MI/electronics repair depot close to home and I dropped off the drivers for their speaker tech to evaluate.

One of the sales guys said they might have re-mag equipment in the shop, perhaps later today I will know if they can help or not.

Edit : the local repair depot failed to produce results, so I sent the 808's off to GPA.

Bubble wrapped and doubled boxed them to survive UPS delivery goons, but IME they can trash anything.
