This hybrid technology is the key feature of the £2,500 ElectroMotion ESL (or EM-ESL) floorstanding front speakers that spearhead this 5.1-channel system. Without the woofer, the panels would need to be huge to generate serious low-frequency depth. That’s why MartinLogan incorporates a woofer into the design, taking care to tailor the crossover network to the electrostatic panel, ensuring that these two types of technology work in harmony. The thing is, electrostatic transducers are invariably found wanting in the bass department.
That’s the tech-lite description, of course. With most brands opting for conventional cone-based designs, it’s ploughing a lone furrow with this tech, but reckons the results are better than anything else available.Įlectrostatic transducers use a light plastic film diaphragm stretched tight between two ‘stators’ (perforated steel sheets coated with an insulator), which are charged by signals of opposing polarity – the push and pull of the stators’ positive and negative charges then causes the diaphragm to move and produce sound.
MartinLogan is famous for creating speakers that blend electrostatic panels with traditional bass drivers, an approach it’s been perfecting since the 1980s. State-of-the-art electrostatic speakers are guaranteed to leave you feeling a bit emotional
