Những điểm nổi bật của loa hi-fi Wharfedale Jade 1 (Cherry)

The Jade 1 is a three way bookshelf loudspeaker that measures 14 inches tall by seven and a half inches wide and 13 inches deep. It tips the scales at a solid 18 and a half pounds. The Jade 1 features Wharfedale's new Crystalam cabinet design, which employs the use of a new laminate technology that is said to improve dampening and effectively kill resonance that often plagues traditional MDF cabinets. From the outside, the Jade 1's cabinet is a sexy piece of design, featuring gentle sloping sides that nearly come to a point in the rear. The back of the Jade 1 plays host to four five-way binding posts, which are arranged vertically. The binding posts can accept everything from bare wire to spade terminated speaker cables.

The Jade 1 features three unique drivers, a one-inch aluminum dome tweeter, a three-inch Acufibre midrange driver and a five inch Acufibre bass driver. Acufibre is a new driver material that mixes a bit of carbon fiber technology with that of more traditional woven designs. Wharfedale takes it a step further by adding a molded pattern to the drivers, which is said to break up standing waves, thus reducing coloration and distortion. The Jade 1's three drivers, along with its aperiodic bass loaded cabinet, are good for a reported frequency response of 65Hz to 24kHz. The Jade 1 has a listed efficiency of 86dB with a nominal impedance of six ohms, making it an ideal candidate for everything from entry-level integrated amplifiers to modest AV receivers and beyond. The crossover frequencies are listed at 710Hz and 3.2kHz. The Jade 1 employs a phase linear crossover that is said to achieve true coherence between multiple drivers, making the three-way design sound more like a single driver or point source design.

Lastly, the Jade 1, despite being a simple bookshelf speaker, is rather inefficient at 86dB into six ohms. In smaller rooms, I was able to get them to sing on as little as 35 watts, courtesy of the Napa Acoustic MT-34 tube amplifier, but it wasn't until I connected them to my 250 watts per channel Parasound that they really came alive. My recommendation would be to power the Jade 1s with at least 50 to 75 watts, and possibly more if you can manage it. Also, because of their low efficiency, the Jade 1s' optimal performance envelope or butter zone is surprisingly narrow. While they sound good at low and moderate volumes, feed 'em a bit of juice and they're simply magical. The problem with this approach is that you can find the point at which you can feed them too much in a single step up the volume ladder, at which point the Jade 1s go ugly early. It won't take long before you discover the speaker's butter zone and, once you do, you'll know where its limits are andvhow to never cross them again.
