Bass improved in Tannoy Ed’s

Bass improved in Tannoy Ed's - audio system Power cords

Bass is always a problem in the audiophile world and it is very hard to get the correct amount of Bass and the way that you want it to sound. There is either too little Bass of either too much Bass. And it really can be a huge problem for the Audiophile to get it just right. I am writing because I had an email from a contact of mine in the Tannoy group. And,  was asking some questions. And, so thought it could be good information for other Tannoy followers.

Tannoy Fan

I am a huge Tannoy Fan and have been for most of my life whilst being involved in the wonderful world of Audio. I have owned so many different models of Tannoy from the Berkeley, Arden, SRMx15, Turnberry’s, Glenair’s, Edinburgh’s, GRF’s, Kensington. I have also listened to many other Tannoy loudspeakers and everyone is different and has its own personality.

Driver 3149

drives 3149

This is the Tannoy “pepperpot” 3149 12″ driver with that was fitted to the Edinburgh enclosures. The driver came with a Tannoy crossover. The crossover 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.

Crossovers Number 0ne

The Tannoy crossover that came with the Edinburgh’s was I think not up to par and it would not give these enclosures the response that I wanted and so I went searching for a substitution

cross over home made

My first attempt was a crossover that was homemade and I found it on eBay from an enthusiast in Rumania. The crosser was hand-built using excellent components. And it crossed over at about 1K. But, did not do what I wanted it to. However, it was an improvement from the Tannoy crossover supplied. And, so, my search continued.

Crossover number Two

This was a very simple crossover and was designed by a Tannoy expert using all the best components available. It was Clarity Caps and Mundorf Inductors that crossed over at 1.2Khz. This crossover had been designed to work with the Tannoy 3811 which was a 15″ driver.

But, I thought I would try it on the Edinburgh’s, The quality of the sound was in a different league. Absolutely clean clear sound and far better than the Tannoy crossover that came with the Edinburgh’s. But, still, the bass was lacking. Not by much but I wanted more!

Crossover number Three

I was determined to get the bass to sound the way that I wanted it too. And, my search came to a very well know and respected Audiophile. Who operates, as “Mainly Tannoy” and supplies professional Tannoy crossovers and components.

Tannoy crossover

This crossover was from the Tannoy professional series and sounded very good. But, did not have the intense clarity of the number two crossover. I decided to get the soldering iron warmed up and made a couple of mods to the crossover. After, which, installed it, into the enclosures.

I also used a very high-grade cable to connect the drivers to the crossover. And, actually soldered all cables directly to the Drivers. The cables were soldered directly and the other ends soldered to the crossovers. And, now the only thing to do was to test the system. Firstly, to see if it all worked and secondly to see how it sounded!

The result

The modifications were carried out at one of my friends listening rooms. My friend has a pair of Tannoy Autographs, fitted with 15″ monitor Golds. And, these are a simply amazing sounding pair of Loudspeakers.

testing both

As you can see, Edinburgh’s look rather humble next to the Autographs. But, it was the sound that we wanted to hear.

There is a saying “Third time lucky” and this certainly was the case. We had everything set up and been listening to our favourite test track. Now, it was time for us to hear what the Edinburgh’s sounded like with the new modified crossovers.

Listening

It only took a few bars of the music and we were both in 100% agreement. The Edinburgh’s sounded absolutely fantastic. They had the clarity in the upper regions plus the middle tines that these pepperpot drivers are renowned for.

But, there was the Bass. OMG, what an amazing sounding bass. It had everything you could imagine. And, the sound was so close to the Autographs it was a shock for us. This was the best sound I had ever heard from Edinburgh’s. Resulting in such a pleasure from what we had done.

Conclusion

If ever, anybody ever says to me Edinburg’s are no good because they lack bass. I will stand up and tell them my story. There is, however, another small point to add to this story. My friend was using very expensive loudspeaker cables made by an American company. My friend paid over 6000 USD for his loudspeaker cables. But, when we fitted my loudspeaker cables the difference was let me say more than noticeable!

  1. I have inherited a pair of Tannoy Edinburgh TW and read your article with great interest. These are solid, large speakers, yet seem to be quite thin in the bass. Can you send me some specifics of what you did to the custom crossovers? Thank you.

    1. Hello Sam

      It is such a pity the Eds lack the bass I know but I did what I could to improve things.

      However, I will state that a good set of cables certainly does make a difference to the Bass!!!!

      To answer your question – If you zoom in and look at the back end of the crossover all I did was
      remove the small light and the two resistors. Which are to the right the light at right angles,

      And that was it.

      Now I am using 15″ Tannoy 3818 in 300-litre enclosures the bass is phenomenal!!!!

      best regards
      Paul
