Dissected a few bolton drivers

somakmaitra · 16th July 2008, 06:16 PM

I have ripped a few bolton drivers wanted to share some data .
The drivers are highly inconsistent.
First a silk dome tweeter.

Attaching a few more images .
there is a sloping ridge in the upper plate of the magnet assebly which slopes down towards the pole peice .
what is the reason of this jagged slope ?

A pair of 4 inch drivers dissected .VERY weird one has an extended pole piece while the other has a normal one both the drivers has the same nomenclature.Moreover one driver has a uneven pole gap .

The 6.5 inch Bolton has an extended pole but lot of hammer marks on the pole piece .

Hope some Fellow DIYers from India would share their views on such drivers

Hi Somak, if the quality is so inconsistent, no point in buying bolton at all.

You are very right vivek but there are no alternatives in Kolkata other than building your own drives

.
The import route is very expensive .I think what sumit did is the only solution ie building your own driver.

nicely told.. I have been searching for a long long time for good drivers. There is not a single alternative available other than Bolton.
