Bowers and wilkins dm 305

Rachel Cramond Thursday, October 25, They call this new form of construction the Prism system and it comprises a plastic moulded back panel having many of pyramid-shaped spikes projecting into the cabinet expressly to break up, and hence reduce the undesirable coloration from internal standing waves, bowers and wilkins dm 305. However, it should still be seen as a non-luxury loudspeaker in comparison with most systems of similar dimensions.

The new DM is a relatively small and affordable two-way tower speaker whose performance belies its size, weight, and cost. The center of the woofer cone has a rigid conical dome, and both drivers are normally concealed by a removable plastic-framed grille. In addition to a conventional circular bass duct whose vent is on the rear of the cabinet, there is also a narrow ducted vent across the front of the cabinet below the woofer. The rear of the cabinet presents an unusual appearance. It resembles an egg-crate, with more than fifty square openings. At the center are the input connectors.

But at least outwardly the system hasn't undergone any significant changes. The rear panel made of acoustically viscous plastic is molded in such way that wedge-shaped structure is formed inside, which increases the efficiency of energy absorption of spurious standing waves. Paper cone of the woofer is also profiled in a special way. Slit-type output of the resonator on the faceplate and the classic cylindrical one on the rear panel are connected with total volume of the loudspeaker. The area of heads' mounting is reinforced by bars. There are two pairs of terminals, spikes are attached. A lot impresses in the advantages of DM, but probably a perfect bunch of mid-top aspect earns the warmest words. The system easily copes with the dynamics of orchestral themes, clearly draws out the most difficult and subtle patterns; the atmosphere of concert hall is clearly felt. A high quality of long-suffering violin sound's transmission is a very serious argument in favor of the tweeter, which supports the image in cleanness up to very high volume levels. The system manages to deliver the nature of vocals to a listener in a good fullness. The bass of DM is correct, a bit dry, has a good depth. The wish to weight the low-frequency foundation appears only at playing harsh rock. In the end, live and full picture is formed almost in any musical material. There is no need to orient the speakers strictly to the listener - the stereo zone is quite wide.

Performance Stuffing dusters into the rear vents I'll try anything in the interests of science robbed the loudspeakers of almost all of their warmth and bass extension. Similar degradation in quality was audible if the loudspeakers were placed too close to the rear wall, and so I soon settled for placement at least half a metre out into the room, bowers and wilkins dm 305. However, it is a middleweight performer with a limited punch.

However, it should still be seen as a non-luxury loudspeaker in comparison with most systems of similar dimensions. It does not simply have a strong family resemblance to the earlier model, it looks uncannily as if the designers have taken a DM and stuck it on top of a box with a moulded fascia whose angled edges carry the DM's profile down to floor level. Of course there is more to the new model than this.

I am inclined to sum up the DM as a worthy floor-stander that looks handsome, despite that modest black ash vinyl finish, and avoids the fiddle of marrying smaller loudspeakers to floor stands. Nevertheless I could hear bass notes that belied this lack of physical weight and decided that the extra structural stiffness and scattering of internal energy achieved by the Prism back panel and bracing was having something of the effect that other designs accomplish with thicker panels, sand-filling, lead shot and so on.

It resembles an egg-crate, with more than fifty square openings. Slit-type output of the resonator on the faceplate and the classic cylindrical one on the rear panel are connected with total volume of the loudspeaker. The cabinets are finished in black ash vinyl with a cloth grille stretched over a contoured plastics frame.

There is no need to orient the speakers strictly to the listener - the stereo zone is quite wide. The nominal impedance is quoted as 8 ohms but this dips to a 4.

They allow the system to be biwired or biamplified, and apparently they are designed for use only with stripped wire ends, which must be passed through holes in the posts and then screwed down; dual banana plugs cannot be used, and even single plugs are extremely awkward to install because of the limited visibility and finger access to the connections. Tweeter height is about ideal and so the main detail to be determined was whether to point the loudspeakers straight ahead or at an angle towards the listening position. There are two pairs of terminals, spikes are attached. Nevertheless, there appears to be considerably more to this loudspeaker than can be inferred from its plain exterior and modest price — in fact, it must be inferred, since the manual is surprisingly reticent about technical details of its design. Our measurement of the external magnetic-field strength at 4 inches from the front panel of the speaker showed a safe flux level of less than 2 gauss, indicating that the DMs could be placed fairly close to a TV if necessary. Experiments with room placement did ameliorate this effect but could not cure it completely. Organ pedal notes can be relied on to expose such irregularities, which do indeed have an association in some designers' minds with the use of reflex enclosures.
