Tannoy is synonymous in many places with the finest public-address systems. The Hi-Fi side of the business may be less well known (to the general public) but is nonetheless an extremely well founded part, producing some high performance loudspeakers, at very attractive prices.

So it was with great anticipation that I received the demo pair of Sensys DC-2 loudspeakers. To cut to the chase, these speakers are definitely on the short-list for my next upgrade.

What brought me to this conclusion? Read on and I will show you my reasoning.


The speakers arrived very well packed - one had been opened and re-sealed previously, but the accessory bags inside looked untouched. There was no audible difference between the two speakers and no visible markings to tell them apart, so I presumed they were both actually brand-new. The reason I mention this is that a used speaker would have already been broken in and would make one speaker sound different than the other for the first day or so.

After reading the instruction booklet from cover to cover, I connected the speakers to one of my amps (an ION Obelisk 100) and used this setup over the next few days for the recommended burn-in period of 24 hours usage. Over this period, nothing was optimized and, in fact, I didn't even fit the spikes until I was ready for some critical testing.

The Equipment

Feeding the Ion amp from my Philips DVD player and using both rock and classical CDs, I quickly found that I preferred to listen to rock CDs with the reflex port foam plug inserted in the Tannoys, whereas, for classical CDs I preferred the fuller bass produced with the plug out. If I had to choose a long-term compromise, it would be to leave the plug in.

The rest of the tests were done with a Quad amplifier fed from a Philips CD player. This setup confirmed my port preferences and, to my taste, suited the speakers better than the Ion.

Test Material and Results

For all sources, I found the sound to be smooth, clear, and revealing. When checking out different speakers you always notice new aspects in CDs, even old favorites like Abbey Road. The DC2s confirmed this, to the extent that I felt I was hearing Paul's studio amp for the first time, including a slight crunch of bass instability on certain tracks. This was present irrespective of volume, and was in the music, not the speakers.

While on the subject of the Abbey Road test, the DC2s sounded incredibly open, instrument placement and vocal location being precise across the audible spectrum. It's reassuring that these old analog recordings were mastered to CD with sufficient care that even after all these years, they serve as valuable test material.

My toughest test of the bass stability and extension is "I Love You" from Surfacing by Sarah McLaughlan. The bass sounded like well-formed, rounded notes rather than the 'humph-humph' you typically get from lesser speakers, epitomized by the bass toobs fitted in kids' automobiles!

More seriously, I have been enormously fortunate in being provided with a private recording, courtesy of the internationally-acclaimed conductor Robin Browning. Without test instruments to back up my assertion, I would still maintain that this recording reveals a completely flat frequency response from the DC2s. More than that, the coherent wave-fronts that the WideBand (TM) technology built into all Tannoy Sensys speakers produces, came through with no smearing detectable whatsoever. Some enthusiasts may have veered away from bass-reflex designs in the past, presuming that the phase-shift from port to listener would damage low-end location/imaging. All my test material produced rock-solid imaging at all frequencies. But more on imaging below.

I ran some further tests using vinyl sources, chiefly the classic Karajan set of Beethoven DGG recordings. I admit to feeling rather disappointed after my listening to the Browning recording. The Quad phono input has a steep anti-rumble high-pass filter characteristic which leaves vinyl sources sounding a bit thin compared with a good CD input. Even so, the DC2s sounded as good as any speakers I've heard using the Shure-Thorens-Quad chain.

Moving back to pop, I like to check-out a particular section in "Tell Him" by Hello: it goes 'chugga-chugga-chug' (onomatopoeically-speaking) and can highlight any inter-frequency dependencies causing intermodulation. I've never heard this section sound so controlled. Not disjointed, just delivered separately. Remarkable.

I like to try genuine mono sources as one of the checks for solid imaging. "Butterfly" by The Hollies usually gets an outing, and the source at all frequencies was straight down the middle. Mentally paying attention to each speaker in turn highlights any differences between the DC2s (and the source/amp chain as well), but there was none.

And finally, a moment that was truly breathtaking. I wasn't particularly listening to the speakers, just enjoying a favorite CD, like we all do. The track was Eric Troyer's "If Only" by The Orchestra. I thought the clarinet-quintet had moved in, and very welcome they were too.

More General Observations

I can't help feeling these speakers are ideal for the larger room. When I moved them from the Ion location in the sitting room to the Quad location in the same room, I found I was naturally sitting at a greater distance from them than before. What a difference this made. Suddenly it all came together - tonal balance, imaging, reality. These are not near-field monitors, so I would recommend a listening distance of 7 feet or more. With this positioning, the sweet-spot is certainly broad enough for family listening.

And on the subject 'family', the speakers are attractive units that should fit into any domestic environment. Many will prefer to have the smoky-grey grille left on. Others might wish to run no risk whatsoever in acoustically filtering the sound by fitting the panels. Tannoy themselves leave the choice to the user. My own preference is to have the grilles in place, but the speakers are certainly attractive enough with them off.

I was surprised just how sensitive the speakers are, comfortable volumes being achieved at very similar settings as those for my classic Goodmans speakers. Note that the recommended amplifier power is from 20 watts upwards. It would be interesting to make a comparison using one of the classic vacuum-tube (valve) amplifiers within the recommended power-range. That will have to remain for another day.


As of this day, the Tannoy Sensys DC2 has a completely clean bill of health as far as I am concerned. There are no vices, and the impact, smoothness across the band, and stereo performance are impeccable. The clarity this new vision has given me fills me with a certain yearning to continue the experience.
