DynaVox V Pulses

No question – the DynaVox impulse V (1600 euro per pair) is huge. So huge like the fun it brings especially tubes fans: No 1600-euro speaker and also can just a few more expensive – from a handful of tube Watts generate impulses V as much momentum as the DynaVox.

When AUDIO tests cheap tube amplifier, the testers are always back and caught in the Middle: almost divine exalted, the transistor colleagues always far superior sound is often only a foot apart from hollow reverberation, by high-frequency harmonic distortion steam-clouded depths in the same device. Between soaring and crashing decides almost exclusively the speakers why AUDIO always topped such tests with appropriate recommendations. Specifically on the claims of amps optimized boxes don’t actually there but hardly, and in affordable price ranges. Until now at least.

To breed, in the form of kippeliger hunger hooks under the years trend, once stately HiFi speakers – apparently by crossing a pencils – wasteland of loudspeaker market in view of the low power amps to enemy territory. For the shrinkage process remains the efficiency on the game: the scrawny speaker, approaching the more efficiency be a Spring mattress.

Adaptable: The generously equipped unit has level switch for “Bass” (actually acts in the middle) and “Treble”. The solid terminals range from the Alublende directly on the printed circuit board.

With the series of impulses, DynaVox follows an entirely different approach that is physically only reasonable, in addition to the slender stems of consensus but radically acts: instead of a collection of highly cultivated small chassis employs the box rough workhorses in the professional field, opts for classic case volume, membrane area, Horn sound leadership and even the support of the rear wall of the hearing room, to get the absolute maximum sound pressure from every Watt. To hell with the lifestyle: overlooks a boost and not hear about.

The heart of impulse V is a broadband driver of the American manufacturer eminence with basket diameter 32 cm, cardboard, fabric surround, Treble Cone – very Old School. Really, it is suitable as full-range transducers but only for instrument amplifiers or maybe small stage monitors. In the impulse V is he (eminence specifies 8 kHz) supported much before the end of his nominal frequency response of a Horn tweeter and eventually replaced after an unusually broad overlap range. Also, the Horn Driver comes from good House, namely from the Brazilian manufacturer of selenium.

Developer Frank the get not only high efficiency of raw material with a refined crossover, a powerful case and an unusual bass vote, but holding line – favourable conditions even for unstable single amplifier of very old school the impedance of the box to 10 kilohertz on the 9 Ohm. In the bass really deep to get off, the box plays specifically with the acoustics; She can and should be directly in front of the wall and played also the AUDIO listening room from this position.

The listening distance prevented the box but not that immediate, packender and live sticky notes to play as pretty much every other box on either side of the 2,000-Euro border – but only in conjunction with amps. At the beginning of the test, the editors made the mistake, an (expensive!) Transistor combination to connect in the impulses of V, and harvested fahle, low-bass, total slack sounds. The furious transformation that made the box after the cheap lyric TI-60 (1200 euros), exceeding even optimistic expectations: tired, singing and realistic precisely filled the bass at “sever” karate (from the jazzy floating rock masterpiece “unsolved”), the listening room.

Each drum accent – fine shiny pool, throbbing bass drum and an explosive snare – got own experience value that had increased almost anywhere: with each twist the volume knob was the listening more to the rehearsal room, drum kit, seemed truthful to pulsing bass and guitar amplifier, to vibrate to flood the space with their specific energy. Borders? Even with the TI-60 (and even with the more expensive T.A.C. K35, which ran hot for a future test) not really. For normal apartments, far more dynamic than you will ever need is in this combination.

Legitimate objections had only classical music fans in the Newsroom: the midrange was not one hundred percent neutral and made especially voices seem sometimes slightly closed. There are also boxes – turn primarily from the perspective of the classics – sharper contour depicting similar efficiency than on a large scale, but slightly soft-edged DynaVox. On the other hand, also classical music benefited from the wide, effortless Dynamics game room – the trademark of this remarkable box.


Who a middle wall space for the DynaVox V impetus finds, comes with a cheap also and a good source (we have used the Linn Sneaky) to a chain that keeps up with scale and dynamics easily with several times more expensive equipment. You give a chance – a rock – or radio plate of the giant box later you will have forgotten any Setup concerns.
