Other than impedance, all acoustic measurements were made with the DRA Labs MLSSA system and a calibrated B&K 4006 microphone. To minimize reflections from the test setup, the measuring microphone is flush-mounted inside the end of a long tube. Reflections of the speaker's sound from the mike stand and its hardware will be sufficiently delayed not to affect the measurement.

The use of paralleled bass units means that the Mani-2's impedance (fig.1) falls to a very low value below the midrange, reaching a current-hungry 3 ohms at 200Hz, which will be…

Fig.6 Totem Mani-2, horizontal response family at 50", normalized to response on tweeter axis, from back to front: differences in response 90 degrees-5 degrees off-axis; reference response; differences in response 5 degrees-90 degrees off-axis.

When I reviewed the $3995/pair Totem Mani-2 in February 1996 (Vol.19 No.2), I was very impressed by this modest-sized but expensive two-way. In particular, the speaker produces an astonishing amount of low frequencies, this due to its compound woofer alignment, which features two 7" Dynaudio drive-units, one mounted magnet-to-magnet behind the other, with a volume of air trapped between the two cones.

For a given bass extension, the compound configuration (patented in the UK by Linn Products as "Isobarik" in the 1970s…

The loudspeakers Vince Bruzzese designs for Canadian manufacturer Totem Acoustic are intended for the long haul. His Model One has been in continuous production since its introduction at the end of the 1980s, and I recently gave a listen to its current iteration, the Signature, to see if the Model One was worth continued inclusion in our "Recommended Components" listing. Similarly, I first reviewed Totem's second loudspeaker model, the stand-mounted Mani-2, in February 1996, with a Follow-Up in October 2001…

I performed my usual set of measurements using DRA Lab's MLSSA system. The 2009 sample of the Mani-2 offered an estimated sensitivity of 84.0dB(B)/2.83V/m, which is within experimental error of the 84.5dB I found eight years ago. Nevertheless, this is 3dB below average, implying that the Mani-2 needs to be used with an amplifier offering at least 50Wpc. Its impedance (fig.1) was very similar to that of the earlier samples and dropped to 3.5 ohms in the midbass and lower midrange, confirming that a good, 4 ohm–rated amplifier be used. The shape of the impedance curve…

Sonus Faber's big reference model is the extraordinary Extrema (footnote 1). Stereophile's writers voted the Extrema their 1992 "Loudspeaker of the Year," appropriately so, I feel, considering its amazing looks and equally remarkable performance. The $14,000/pair Extrema is built like a tank, and is capable of producing a seriously big sound, even in quite large…

Whether just sitting there or playing music, the Guarneri is never boring—it's fundamentally true to the spirit of the music it plays.

The Guarneri is loosely based on the "larger-than-life" Sonus Faber Minima Amator (reviewed in December 1993, Vol.16 No.12, p.174), which costs…
