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 very wide and so much information can be 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 really think hard to find the best solution because drivers have different sonic signatures. I decided 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 actually make or break the final sound you hear from your listening position. I have known people to build beautiful cabinets but when they actually sit down to listen they find the sound is not what it should have been. This is in most cases the incorrect selection of crossover.
The crossover necessary for this driver to perform correctly is actually 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 was 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 that was 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 sound 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 was done with the cross members and bracing bars. The Enclosures were filled with two layers of WoolRock and a single layer covering the crossover
When completed the system sounded exactly as it should be and I was very pleased with the results I have had many friends to listen to my system 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 have been said by many of my friends who have heard my system.
