MONOPULSE Model 42A [£3,445] £1995

New, old stock. Audiophile. No compromise hi-fi loudspeaker design. In black
Shown below in burgundy cloth [actual model in black not burgandy], with Gunmetal steel

This is a major visual statement as an audiophile speaker, at 108cm high x 23cm wide x 25cm deep, and 25Kg each.

Power handling is 300 watts continuous, 550 watts maximum, and 1,500 watts for 10ms.

The 200mm, 8 inch, Kevlar-coned LF drive units, large for the relatively slim enclosures, have 4 layer voice-coils and 40oz magnets. They have long excursion before they become non-linear, so even at high volumes with high bass content, there is no uneasy feeling of overloading.

They are coupled to separately suspended ferrofluid-cooled, 28mm, silk domed, 30kHz, HF drive units with Neodymium magnets. These are rated at 500 watts for 10ms.

Thanks to two 6 inch bass drivers which are perfectly adopted to the tweeters, a passive frequency switch can be abandoned. Due to this direct "quasi-Active"-interpretation the full-bipolar 3&3 fascinates one with it's ease and homogeneity of the rendition of musical reproduction, almost like in the concert hall.

OPERA PLATEA speakers, beautifully made, excellent quality, boxed, £475

The Platea's 190x900x200mm (WHD) cabinet is, like every Opera model, made from solid, 25mm-thick, interlocking hardwood sections, with extensive internal bracing. Each cabinet is hand-polished with five coats of lacquer to protect and enhance the natural wood finish, with mahogany as standard. As is the Italian wont, all of the enclosure's edges are rounded to eliminate the possibility of diffraction problems (while enhancing the looks), and the rear-firing, flared port "...allows good breathing at high volume levels". Actually, that should read 'no breathing', because the bass is whoosh- and woofle-free. The cabinet's lower cavity can be filled with lead shot or sand for additional mass loading.

The Platea is fitted with the same 19mm doped silk dome, three-fixing SEAS tweeter specified to Opera's requirements and now found in the Duetto. Below it and crossing over at 2.8kHz is an ATD-made 130mm bass/midrange driver with copolymer cone and hefty chassis/magnet construction, specially developed to provide the extra damping demanded by a larger enclosure. The crossovers, hand-made and tested by Opera, use audiophile-grade components including high-saturation, self-cementing inductors and close-tolerance non-polarising capacitors. Drive-wise, this system is as easy and amp-friendly as the Duetto, with a nominal 6 ohm impedance, sensitivity of 89dB/1W/1m and recommended amplifiers including valve amps of 12W or more, or solid-state amplifiers of between 30W and 80w.

The Platea's forte is acoustic music, well-recorded vocals, mellow jazz and other forms which can exploit its way with subtle harmonics and textures. The dynamics of the speaker are such that it will not crack under the strain of excessive levels and it can just about cope with the speed of the transitions present in the choppier, noisier depths of Prodigy recordings and other Intel-inspired ca-ca. If anything, the Plateas are not clinical enough to respond properly to technoid sounds, a trait some might classify as a lack of absolute refinement. But feed the Platea a diet of music with high emotional content and they almost glow.

The message is one of involvement, of music embracing the listener. And the Opera Plateas will stick you right in front of the performance, with a room-filling display. So maybe it's no mystery why Opera called this little beauty the Platea. Because 'platea' is Italian for the stalls in a theatre. Which is exactly where this speaker will place you.
