Tannoy gold 12" cabinets

Ah, beautiful city. I have a photo on my wall I took from a hotel room of the city at night, showing the city lights, and the harbor, with the moon at its brightest. Got engaged to my wife that night. Fond memories.

I am still building. What I figured out is that it is very much about the cabinet volume and not what dimensions you use to get there. Unless you are skilled enough to build or want to spend thousands on really complicated cabinets.

The 12" golds work best apparently in cabs of 90 to 205 litres. WxHxD x .61 or convert cubic inches to litres on line. Mine ended up an interior size of approx 125 litres after calculating in driver and bracing. 38" T x 16 x 13.75. 1" Baltic Birch. This is apparently a favourable size.

I am now going through porting and tunning. I am lucky enough to have professional help with this stage of the build. Correctly tuned, this cabinet should get me down to about 33hz which is very good.

I did not mitre I used but joints and re veneered the tops and bottoms to cover the end grain. My finished product will resemble the DeVore Fidelity Orangutan 0/96

This is a fairly simple design to build. I have  not built Cabinets before but do have solid basic wood working skills.

I would be happy to answer any questions you have about my process or tricks I learned along the way. I have never actually heard Tannoys so am  really looking forward to it. I will post my impressions when I get there.

Cheers. Paul

I am not an expert- you may want to check out the site diyaudio to get more info. That's a great resource. 

Having played around a bit with my own speakers I can suggest if you go ported use some interior wall lining and minimal stuffing. You want to retain the 'life' but still decrease back reflections through the cone. That's a tough balance to find. 

Also if port use two ports for each speaker it seems to work better for a larger driver. Don't be tempted to tune the Fb too low. That driver you may find a tuning of anywhere from 45hz to 52 hz works better in that size cabinet than something lower. ymmv. 

Build the cabinet so it's somewhat easy to pull the back off or the driver out to make adjustments. 

There are some great modeling programs available. They can work well I think- but in your room it really may boil down to trial and error once you have it fairly close by spec.
