how to dismantle huge whalfdale bass speaker

[tackon]

I have a large bass whalfdale speaker with a huge magnet bolted to its base, and i'd like to know how I can dismantle it so that I can access the wire coil ?

What's the model number of the Wharfdale?

And, uh, what do you plan on doing the the "wire coil?" I assume you mean the voice coil.

the speakers are called Wharfedale E.Seventy and the driver is a 10"moving coil bass driver 2513 AERN 102.60 68.
Guess its the voice coil that id like to insepect for damage.

Assuming you have no history in loudspeaker repair; You will not be able to view nor do anything about a potentially damaged or melted voice coil.

You can, however, test whether or not the driver has continuity, by using a 9V battery or a multimeter-set to Continuity. Do this directly to the driver, after any amplifiers or passive crossovers built into the speaker cabinet.

As a side note, you can also use the battery method to test a tweeter (hi-freq) driver. But use either a AA or AAA battery, DO NOT use the 9V for tweeters.

Thanks for your reply. Have completely dismantled speaker and discovered that the voice coil had melted and become stuck. Realized that by cutting around the edge of the cone I could pull it and the voice coil out. Many thanks for reply.

You have just greatly increased the chance of the cone ripping apart while in operation. Try to take it easy on that sub and be prepared to replace it if you don't.

If you haven't already, try to patch the cut you made, not just glue the seams back together.
