    Default Replica Tannoy GRF-R Narrow/slim versions

    Here's a pair of speakers I recently made that were delivered by Pallet transport to Stafford today.
    They are already unpacked and installed in a dedicated music room.

    These feature tear drop baffles in the throat of the back loaded horn for bass cleaness, internally mounted Tannoy crossovers and switching boxes (after market X/O's can then be fitted easily) with no slots cut out in the rear panels.
    Finished in clear spray lacquer for an attractive tough finish.

    They are pictured here in my workshop (no fancy photo shoot I'm afraid).























    System: Turntable : SP10 MKII slate plinth, Custom Ebony tonearm board, Arm : Fidelity Research FR64s, Cartridge : SPU Royal N. SUT : Lundahl 1:13. Phonostage : Icon Audio, Streaming RPi/Kali reclocker -> I2S -> DSP XO / Pre / 4 DAC's : WAF Najda, 5 Poweramps : 3 x EL84 SET's, 2 x D class amps on bass channels, Speakers : 5 way front loaded horn system: 2 X Tapped sub 15" LF drivers / 2 X Exponential mid bass 15" drivers / Tractrix 200Hz mid horns with JBL2482's, / Tractrix 550Hz upper wooden horns with factory refurb'd Vitavox S2's / Raal Lazy Ribbons as high frequency tweeters.

    Oh my god! There's nothing wrong with the bidet is there?

    “Nothing discloses real character like the use of power. It is easy for the weak to be gentle. Most people can bear adversity. But if you wish to know what a man really is, give him power. This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".

    “You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”

    "You don't have free will. You have the appearance of free will.”

    “There's a war out there, old friend. A world war. And it's not about who's got the most bullets. It's about who controls the information. What we see and hear, how we work, what we think... it's all about the information!”

    Lovely job Steve.
    “Music has always been a matter of energy to me, a question of fuel. Sentimental people call it inspiration, but what they really mean is fuel. I have always needed fuel. I am a serious consumer. On some nights I still believe that a car with the gas needle on empty can run about fifty more miles if you have the right music very loud on the radio”
