What would a cone and surround cost on the HPD 12” pair…? I have the chamois surround and original cone (see above) which is great but at the same time hard to know if they are performing optimally either.

Lockwood Audio advertise a price for HPD 315 cone assemblies at 380 British pounds, plus postage.                sales@lockwoodaudio.co.uk               07813041959.

 If the original cones are in good condition, then a replacement foam surround may be a more economical solution. Bear in mind that the chamois surround may have been used as the earlier foam surrounds did not last all that long in humid climates.

By the time you add shipping and GST that is probably more than they are worth as working drivers!

It looks like the correct parts to replace the cloth suspension on my Tannoy 12" LGM K3149 drivers are not available. Does anyone know of an aftermarket alternative? 

Is there a future for them? Only one is torn, the other seems fine for now.

Thanks

The first step would be to measure the inner and outer diameters of the 'M' profile cloth surround, also the diameters of the angled flange at the edge of the cone and the diameter at the inner edge of the frame where the surround attaches.  I would suggest that a conventional cloth surround, with 3 to 4 corrugations be used rather than the 'M' profile type which tend to be low compliance types. Try Queensland Speaker Repairs for suitable replacement surrounds. Skillful repair work is required if the end result is not to look messy.

I have very recently score a couple of Monitor Gold 12s in cabinets. They sound truly wonderful ,  The drivers are rear mounted but I have the desire to front mount them (just a feeling I have)

 

Should I do it or will it be a retrograde step?

 

I welcome your knowledgeable comments and suggestions.

 

Thanks

Hey there , I think this would mostly depend on what cabinets , if it's an immaculate set of factory built lancaster 12's then from a collectabillity point i wouldn't do it but if they are in locally made cabs like most are then there is nothing to be lost,  less refraction from baffel , easier to remove the driver ect.

If you haven't found the correct suspensions yet I can share a link with you on where together them , I've done a few hardened k series surrounds now, and undoubtedly to keep t/s parameters even i would do both drivers

 Thanks for the reply. That is what I wanted to hear, especially from you.  The cabinets are good but not collectable .  Now to get busy

Thanks. I ended up selling the speakers, something I never thought I would do. The tech. Said he could get the cone and surround for around $800 and the buyer was going do that route. It would have been worth the outlay for me but I was fed up of the waiting on technicians.

That's a shame , I haven't been really active on here for a while , I normally source the surrounds made especially for k series drivers from Germany and they come with the foam dress ring around $75 each and about 1h per driver to replace

It will be worth it , in most cases the front baffel will be the same thikness as the frame so if you trace around the driver and cut that out then make a sub baffel to mount from inside the cabinet it will be perfectly countersunk , this is the method the 70's arden , cheviot  factory ect cabinets use

For future refferce for anyone that needs hardened k series surrounds , trying to treat them is only a very short band aid fix , they always require replacement to get F/S back down to deliver low end again , also smoothes the mids out allot

After I sold the Tannoys I picked up a pair of Boston acoustics A40 with rotten surrounds. Changed the surrounds and cap and the sound great. Just to prove that I could do it.

Hi Alex,

Further to the concept of changing my Monitor Gold 12s from the rear to front of the baffle, what do you recommend for a gasket on the backside of the frame?  

Thanks, in advance.

Never mind.... I have it sorted

It appears that my Monitor Gold 12s are mounted in "Onken Cabinets".

 

Does anyone know of or have used Onken Cabinets? 

 

Your opinions are very welcome
