Parts freaks will delight in the component-heavy crossover (which operates at 5.6kHz). Eschewing buzz-word brand names but not cutting corners, Dente has filled the board with mil-spec goodies, as I learned when he disassembled the speaker in my studio so I could take a gander. Among the ingredients are air-core coils made from double-insulated copper which has been 'polyester catalysed against vibrations', high voltage/high current metallic polyproylene MKP capacitors and high power non-inductive 'armoured' resistors; all parts are specified to 1%.
Specs-wise, the TUG is not the beast than I thought it would be, partly because Dente did not want to preclude the use of tube amplification. The TUG's mean impedance, encompassing 28 values measured at thirds of an octave, is 11.5 ohms; sensitivity is a high 96dB at 1m for 2.83V (0.70W). The company claims that the maximum SPLs obtainable are 124dB, but I wasn't even remotely inclined to challenge this. Suffice to say, playback levels were never an issue. Should owners wish to test this claim, the TUG will allegedly handle 250W, with only 194 of 'em needed to reach the 124dB point.
Unaccustomed to speakers so positively gregarious in their willingness to mate with all manner of amplifier, I was able to use everything from the luscious but low-powered Unison Research Simply Two integrated tube amplifier to the monstrous Krell MDA300 monoblocks. In my listening room of circa 4x7.5m, I was unable to make the speakers scream in pain. Indeed, I had to work at making even the Simply Two clip with any audible clues. Quite simply, the TUG is an easy, efficient load which allows it to work in systems with even the humblest of power amps.
What the TUG will not tolerate is any harshness preceding it in the chain. I'm sure I faced that SEAS tweeter before, but I don't recall it spinning into chalkboard scratch antagonism with such ease. This isn't level-related at all. The tweeter simply doesn't ameliorate, mask nor ignore edginess, brightness or sibilance...and still I kept the toggle beneath the speaker in the brighter of the two positions. Why? Because, in addition to sounding 'duller', slower and less detailed, the -5dB position also seems to affect the imaging capabilities. And the TUG, by virtue of its sloped and narrowing baffle, images better than a speaker of its cubic volume tends to do. I was overjoyed to hear that it could position sounds with the skill of an LS3/5A, with nearly the same three-dimensionality.
Where the TUG clearly betters mini-systems, though, is down below. The cubic volume, the port, the sensitivity and the stone-dead cabinet all collaborate on the reproduction of smear-free, fast, deep bass. Though not quite as rich as the similarly-priced Ruark Equinox, the TUG comes close to the British marvel for impact and control.
