Penjelasan Produk

M340 - True audiophile heaven
Next in the M-Series is the M340, with four 41/2-inch (11.4cm) woofers and a 41/2-inch mid-range driver. As with all the M-Series models, the M340 incorporates a 1-inch EWB soft dome tweeter for Extended Wide bandwidth performance This sublime combinationof four powerful bass drivers, one specialist midrange drive, and a uniquely "open" tweeter is quite simply an audiophile's heaven

Main Futures:
- EWB
  All floorstanding and bookshelf speakers incorporate the highly-acclaimed EWB soft dome dome tweeter, This completely opens up the mid-high to high frequency ranges to create an almost infinitely wide, wky-high sound stage. It's and Extended Wide Bandwidth effect that is totally unique to Boston Acoustics

- Loaded Mid Range Driver
  The midrange used in M350 and M340 has a unique visual identifier;four small recrangular "tabs" on the inside edge of the surround. These tabs add mass to the midrange to achieve a smoother frequency response at the top of the drivers operating range. This technique of using mass to smooth the response of the midrange has a specific design benefit. It eliminates the need to try and achieve the same sonic result by adding components to the crossover netwotk.
- Lo-Q cabinet
  All m-series models are framed by a doublelayer side panel. Each of the two layers is 10 mm thick, an sandwiched between them is the Boston Acoustics specially-developed SDF damping elastomer. This absorbs the internally generated cibration and ensures that the speaker cones remain autonomous. So absolutely nothing is added to the music, and absolutely nothing is taken away
- Crossover
  
If the drivers are the heart, and the cabinet the body, the crossover is the soul of the speaker. The crossover is an electronic circuit that directs the appropriate sound range to each transducer and maintains the phase/timing accuracy between all of the transducers. All the parts in the crossover - resistors, capacitors, inductors – have an effect on the sound, and choosing the right parts will deliver the sound that the system is truly capable of. Special elements such as low loss film capacitors and low distortion laminated silicon steel core inductors have been used at all critical areas. 
- Separate Chamber
  In addition to utilizing Lo-Q contrcution the M350 and M340 also utilize a separate Internal chamber for the Mass-Loadded midrange. This acoustically isolates the midrange from the woofers inside the cabinet so they do not interfere with each other. Another benefit of the separate midrange chamber is that it doubles as a reinforcing brace near the top of the cabinet to add rigidity and reduce cabinet vibrations even further.
- Standing wave prevention
  A common problem with conventional floorstanding speakers is the build-up of standing waves and their consequent inteference. No such risk with the M-Series. By using four smaller bass drivers in the M350 and M340 (rather than two larger ones dual oscillation and standing wave creation is simply not possible)
- Laser-Based vibration management 
  Laser-based vibration measuring has helped degine the exact, optimised position for each cabinet's internal bracing and mounting locks. This ensures that negative resonance are not just shifted to other frequencies but are totally minimised.
