                The Audio Physics line is from Germany where precision engineering
                  is a way of life. But while there is a lot of engineering
                  in this design, and though important and of interest to the
                  manufacturer and some audiophiles, I am of the opinion that
                  engineering alone does not guarantee good sound. Therefore,
                  this review is going to focus on the loudspeakers’ performance
                  and sonic accomplishments when they are used in an audio system
                  to reproduce music. However, the loudspeakers have numerous
                  indicators that point at design proficiency and quality, likely
                  based on Audio Physics’ 25-some years of experience.
                  I have heard APs at trade shows, but have never auditioned
                  them under controlled conditions, so I can’t comment
                  on the company’s history and/or its past achievements.
                  I do know that they enjoyed good press with the Tempo 25 — the
                  25th anniversary edition — often compared with the lower
                  priced Tempo model, both belonging to the company’s high-end
                  series. AP actually produces 22 models divided into four categories/series
                  of loudspeakers and includes home theatre components.
Appearance
The slim, immaculately finished enclosures are stylish and
                    present a tastefully designed almost understated elegance
                    that fits almost any decor. They are slightly tilted toward
                    the rear (for time alignment) boast great single-wiring terminals
                    and adjustable spikes. For a truly nice final touch, the
                    supporting structure is covered with four black covers, which
                    adds to the visual appeal and shows the company’s regard
                    for precision as well as appearance — a touch of class.
                    A number of finishes are available — check the AP website. 
The Sound
For the initial auditioning session, I had the Tempos connected
                    to the Genesis power amplifier, pre-amplified with the Allnick
                    (tube) and a Dolan (solid state) designs, with the source
                    components an Atoll CD player and Origin Live turntable/arm
                    with a Dynavector moving coil cartridge and cabling by XLO
                    and Argentum. Earlier, these electronics had been connected
                    to a pair of Genesis 5.1 speakers (about $25K) and I have
                    listened to the system for months thus familiarizing me with
                    every component’s voice. I reasoned that by simply
                    replacing the Genesis with the Tempos, I should get a pretty
                    good first impression and a general idea of the Tempos’ sonic
                    temperament. Well, it didn’t take long to find the
                    speakers’ voice, but what should have been routine
                    for this reviewer, became a bit of a thrill and a lot of
                    anticipation. Thrill, because the Tempos sounded real good;
                    and anticipation because I wanted to test them with the other
                    amplifiers I had at hand — the Bryston 7BSST Squared
                    monoblocks and the Atoll 400 series integrated amplifier.
With the Genesis power amp, the Tempos sounded entirely relaxed.
                  I never had the feeling that the amp labored or that there
                  were restrictions relating to dynamics. Surprisingly smooth
                  highs, clear midrange and solid deep bass made this system
                  sound musically pleasing with but a few slight upper midrange
                  dips (around 900 -1000Hz). Outstanding imagery and the speakers’ knack
                  to delineate detail, led me to believe that I am actually hearing
                  the amplifier’s characteristics, while the loudspeakers
                  faithfully reproduced the musical signal they received. That’s
                  a good thing, of course. With the Bryston 7BSST-Squared connected,
                  the Tempo 25s didn’t sound as relaxed as with the Genesis
                  amp and, in fact, exhibited a bit of tension — the kind
                  that borders on anticipation for things to happen. When I played
                  back my favourite Beethoven recording of the 5th with Fritz
                  Reiner and the Chicago Symphony (JVC CD) my anticipation turned
                  into appreciation as the speakers faithfully reproduced this
                  very complex musical material. Basses and cellos —stage
                  right, violas in the centre, first violins —stage left,
                  percussion way back centre and horns and woodwinds just in
                  front of the percussions. In other words, the loudspeakers
                  easily recreated the space, the position of all instruments
                  and the many subtle tonal shades and dynamics of the 50-some-piece
                  orchestra. While I heard plenty of detail, I was impressed
                  with the way it was presented, not as a highlight, but as a
                  beautifully realistic blend and part of the orchestral arrangement.
                  The loudspeakers’ ability to recreate a solid three-dimensional
                  soundstage image was in the same league as the one I recently
                  enjoyed at a live performance at the famous Musikhaus in Vienna.
                  I believe that the Tempo 25s do not add spatial expansion or
                  contraction, but do provide the impression of proper boundaries
                  and out-of-the-box sound that doesn’t seem to emanate
                  from their slim enclosures. The Bryston amps introduced a little
                  more bass resolution and a slight increase in harmonics above
                  fundamentals. The midrange segment from about 170Hz to 1300Hz
                  was almost the same as with the Genesis amp, but in the mid-highs
                  from about 2500Hz to 5kHz, the Bryston amps had a warmer tonal
                  character with additional presence as this relates to harmonics.
                  Top frequencies were identical with both amps and showed that
                  the Tempos’ tweeters never sound edgy, extend well into
                  the dog-whistle range and handle harmonics — the element
                  that provides listeners with the essence of instrumental timbre
                  and tone. Goes to show — there is never too much power
                  even with an efficient loudspeaker.

The Atoll integrated amplifier, when connected to the Tempo
                  25s, didn’t impress me. While it did provide decent bass,
                  mids and highs, this system combination lacked harmonics and
                  sounded rather clinical (coldish) when compared with the other
                  two amps. Nevertheless, imaging was great, resolution was in
                  line with the other amps and I’d call the all-round sound
                  quite good, but not yet high-end.
Synopsis
The Tempo 25s never sounded less than involving with all amp
                    combinations, thus showing a relatively neutral quality.
                    Though I didn’t have a good vacuum tube amp in house
                    with which to try them, I’d say that any such design
                    would sound great. However, in my system with the 700watt/channel
                    Bryston 7Bs the Tempos reached peak performance elements
                    usually reserved for much higher priced designs. Not only
                    was the bass more harmonious and tighter than with the other
                    amps, there was more of the midrange presence, better transparency
                    at top frequencies and significantly better harmonic complement
                    around fundamental tones. The company’s slogan No Loss
                    Of Fine Detail is appropriate and spot on.
Commentary
As with all system combinations, it is important pay attention
                    to every component’s contribution to the end result — the
                    music. Though manufacturers will make claims about the quality
                    of their products, and there are, of course, specifications,
                    it is wise to use the information carefully. It is best to
                    listen and trust you own ears (or mine). Synergy has no guide
                    and cooperative interaction is found only by trial and error.
                    Some folks have developed a sixth sense, but most have to
                    rely on their audio guru — and he/she could be wrong
                    as well. Having said this, I believe that the Audio Physics
                    Temp 25 loudspeakers feature a high degree of sonic neutrality
                    and allow the electronics — amp, preamp and source
                    component — to perform at their best (or worst, as
                    the case may be). Therefore, the sound of your favourite
                    components will be reproduced rather faithfully. This, of
                    course allows the end-user to choose the kind of sound he/she
                    prefers. 
As the Tempo 25s were the first I have reviewed of the Audio
                  Physics brand, I couldn’t compare them to the standard
                  model or any others in the line-up. However, considering how
                  well they performed, their build quality and their superb musical
                  caliber, I can only recommend them to anyone looking for high-end
                sound at a relatively reasonable price.
