![]() The crossover frequency is 4.5kHz, and the speaker’s claimed frequency response is 85Hz to 20kHz. This speaker has a polypropylene cone, which was out of style even in the 1990s, while later versions of the speaker used Kevlar. On top, a wire mesh grille protects the 50x110m Linaeum dipole driver beneath it, a molded plastic top plate is affixed to a rather unglamorous, matte grey finished metal box that houses the crossover and the 130mm mid/bass driver. The LX5 is a tiny loudspeaker with dimensions of 267x162x165mm (HxWxD) and a weight of 3.4kg per. Linaeum also produced its own line of loudspeakers, employing its patented tweeter, which is believed to have a thinner, more sensitive, better sounding, but arguably less durable diaphragm in this guise. To add to the confusion, the Realistic Optimus Pro LX5 was also offered as the Genexxa Pro LX5, which was virtually similar. It was released with the less costly Optimus Pro X77 and LX4, which used a less desirable front baffle-mounted tweeter, but the LX5 featured a top-mounted bi-directional tweeter on a baseplate. Linaeum, an Oregon-based high-end speaker manufacturer, supplied the tweeter subassemblies, which were shipped to Malaysia and placed into the speaker box before being coupled to a relatively generic mid/bass driver. Tandy Corporation produced the Realistic Optimus Pro LX5 speaker (Realistic was the speaker brand of that company, which sold in the US via Radio Shack stores, and in the UK exclusively via Tandy). That’s impressive, but the story doesn’t end there. They effectively act as a dipole, radiating both front and back, resulting in a totally different listening experience than a traditional dome tweeter - as soon as you put your ears on them! These create sound by rotating back and forth in the air. The voice coil of the Linaeum tweeter is vertically flattened and suspended between opposing rectangular permanent magnets on either side, which push or pull two semi-cylindrical sheets of mylar film fastened at the other end. As the current alternates, the dome or cone travels forward or backward, causing the air to move and produce sound. In traditional dome tweeters, the electrical signal transporting the audio goes through a coil of wire suspended between the circular poles of a ring-shaped magnet. It’s one of the most fascinating loudspeakers of its day, made all the more remarkable by the fact that it was a low-cost design. If you blink, you’ll miss it – but there are still quite a few about. One of the most intriguing to yours truly was the Linaeum ‘figure of eight’ dipole design, which was first introduced to the British hi-fi market in 1995 with the quite odd-looking Realistic Optimus Pro LX5. Ribbons have recently regained popularity, although other types have also come and gone.
