The classic Model 42A hi-fi loudspeaker and the newer Model 82A have just undergone a restyling.
The two models are now similar in appearance - but the Model 82A has the quarter-inch rolled-steel surround, slightly further back.
This Model 42A is in Burgundy cloth and Gunmetal steel. The height is 110cm and the width 26cm.
More rounding of the front panel contributes to the powerful styling.
This picture shows contrasting colours - but the units look fantastic in all black, with contrasting surface textures - more difficult to show on a photo.
The new detailing of the top, is truly, form following function.
The HF unit behind the removable top cover is separately suspended on the rolled steel surround.
This separate mounting on the heavy steel, limits enclosure- transmitted intermodulation between the two drive-units.
This is augmented by the acoustic foam break which limits air-path intermodulation.
The steel itself is aligned to give absolute precision of impulse timing.
The rear of the main enclosure, and of the HF unit mounting, are covered in acoustic foam to limit spurious sound emissions to the rear.
The same function is performed at the sides by the quarter-inch rolled-steel.
This heavy rolled steel is clamped to the all-bonded cabinets via high-hysteresis-loss polymer.
To minimise unwanted emissions from the front panels of the Models 42A and 82A, steel is added to the inside of the front panel.
As an optional styling feature some of this can be mounted externally. This serves to break up the front panel visually as well as acoustically
This steel is finished to match the rolled-steel surround of the enclosure.
The steel is mounted asymmetrically - one of a pair with the steel on the left - the other with it on the right.
In all, this gives unrivalled enclosure deadness to the uncompromising Models 42A and 82A.
Chunky spike holders on the base, match the steels.
Extra long spikes for stability on thick carpets are available.
So are slightly-rounded nylon "spikes", which are more suitable for hardwood floors.
Both of there are supplied as no cost options.
Below is the slim MonoPulse 32S in Champagne cloth and Metallic Bronze steel.
The height is 92cm and the width 17cm.
This modernistic hi-fi design is available in the full range of ten cloth colours and five steel colours.
The 62S shares the same slim styling, being only 1.5cm deeper.
This Model 32S is in Chocolate cloth and Metallic Burgundy steel.
The steel top, houses the super-tweeter, which takes the frequency response of the Models 32S and 62S to an airy 30 kilohertz.
This photo also shows the profiled top.
The rear of the Model 32S is similarly profiled.
This photo also shows the foam back which is common to all MonoPulse models.
The purpose of this is to reduce unwanted and out-of-phase emissions from the rear of the enclosure.
The bi-wire terminal panel will take 5mm bare wire, 4mm plugs, or 7mm spades.
