The Tannoy 3818 driver is one of the best sounding drivers that I have ever heard. I consider it the best driver for testing all types of Audiophile cables. The range of the driver is extensive, and so much information heard.
I have heard and owned many Tannoy Loudspeakers my life. When I decided that I wanted a Loudspeaker for testing audiophile cables, I had to think hard to find the best solution because drivers have different sonic signatures. I chose the only way to get the sound I wanted was to build everything myself, and so my search began.
It took me about five months before I finally found a driver from a company in London, and I considered myself very fortunate to have found it. The 3818 drivers are 15″ dual concentric with Tulip waveguide and were made and fitted to the Glenair enclosures.
The crossover fitted to the driver can make or break the final sound you hear from your listening position. I have known people to build beautiful cabinets, but when they sit down to listen, they find the sound is not what it should have been. And, in most cases the incorrect selection of crossover.
The crossover necessary for this driver to perform correctly is 1.1K. And, I chose components from ClarltyCaps and Mundorf. Because I consider them to be amongst the finest in the world, the cabling that I used cryogenically treated as I have carried out tests with and without this treatment and prefer the cleanliness and transparency the cryo treatment offers.
The Driver in the picture is the 3818 fitted to the Glenair enclosures. And, specifications are as follows –
- Dual Concentric™ high-frequency 33mm (1.75”) aluminium alloy dome with Tulip WaveGuide™
- Dual Concentric™ low-frequency 380mm (15.00”) treated paper pulp cone with HE twin roll fabric surround. 52mm (2.00”) edge wound voice coil.
- Recommended power: 50 – 225 Watts Continuous power handling: 135 Watts RMS
- Frequency response: 32Hz – 25kHz -6dB
- Sensitivity: 95dB (2.83 Volts @ 1 metre)
- Nominal impedance: 8 Ohms
The Enclosures were built by using 25 mm MDF and were designed to give a capacity of 300 Liters. The sturdy material used was WoolRock. The cabinets were internally braced and fitted on SoundCare spikes.
The build was done very carefully with every panel screwed and then glued into place. The same is done with the cross members and bracing bars. The Enclosures filled with two layers of WoolRock and a single layer covering the crossover
When completed, the system sounded precise as it should be, and I was delighted with results. I have had many friends to listen to my plan, and we have changed amplifiers, CD players and tested many different cables, and the results in every case are better than expected. I think the words that I will always remember are that is one of the best sounding systems that I have ever heard in my life and these words said by many of my friends who have listened to my system.
