How to improve the bass in Tannoy Edinburgh

how to improve the bass on tannoy EdinburghsBass or rather lack of it has always been a problem in the audiophile world. In most cases it is hard to get the correct amount of bass and the way that you want your system to sound.

How to improve the bass

The Tannoy Edinburgh is the subject of much discussion and so I have written this blog How to improve the bass  to share my findings and hopefully it will help.

Tannoy Loudspeakers

I have owned many models of Tannoy from the Berkeley, Arden, SRMx15, Turnberry, Glenair, Edinburgh, GRF’s, Kensington and others. I have listened to other Tannoy loudspeaker systems and everyone is different and has their own sound.

The driver ~3149

drives 3149This is the Tannoy “pepperpot” 3149 12″ driver with Alinco magnets. This was the driver that was fitted to the Edinburgh enclosures. The Tannoy driver came with a crossover that was first order HF and first order LF and set to crossover at 1200 Hz. The driver had a frequency response of 28 Hz to 25Khz and a sensitivity of 94db.


I felt the Tannoy crossover that came with the Edinburgh was not up to par and it would not allow the enclosures the response in the way that I wanted. I decided to look for a replacement crossover and this is my story of how to improve the bass.

cross over home made

The first crossover I found was build by enthusiast who lived in Rumania. The crossover was hand built, used top of the range components and crossed over at about 1K. I had several emails with the owner who was able to answer all my questions perfectly as he had great knowledge in this field. The crossover arrived and I connected it up and sat down to listen. Unfortunately the crossover did not make any bass improvement so my search continued.

The second crossover was build for me by a Tannoy expert who lived in London. Again we shared many emails and it took over a month before the crossover finally arrived.

The components used were “Best of the best”. The Capacitors were from ClarityCaps and Inductors from Mundorf. The crossover frequency was set at 1.2K. Cabling was pure silver and mounting board was hardwood. When I connected this crossover I had a big shock because the difference really made a big impression. There  was more air to the presentation and the range expanded. But even though the bass had improved I still wanted more!

The third crossover was from the Tannoy professional series with a frequency set to 1.3K and supplied by “Mainly Tannoy” from Hampshire in the United Kingdom.

I was very happy when the crossovers finally arrived and the installation complete. But to cut a long story short I was still missing the depth of bass I was looking for. I decided to get the soldering iron warmed up and made a couple of mods to the crossover and installed it into the enclosures. I used a studio-grade cable to connect the drivers to the crossovers and actually soldered all cables directly to the drivers.

The result

My friend has a pair of Tannoy Autographs fitted with 15″ monitor Gold’s and have a simply amazing sound and as you can see the Edinburgh looks very humble next to the Autograph!

testing both

It only took a few bars of music to hear how the Edinburgh”s sounded. They had clarity in the upper regions plus the rich middle tones the “Pepper-pot” is famous for. The bass was now in another league and the best that I have heard from my Edinburgh’s and my friend agreed.


If anybody ever says’ “The Edinburgh has no bass” I will stand up and tell them this story because it shows what a crossover change can do.

My friend’s loudspeaker cables cost over 6,000 USD. But when we fitted my loudspeaker cables the difference was let me say more than noticeable ~ read more
