The crossover network is The painstaking design og our unique 2 Drivers 3-Way crossover network has enabled us to use a minimal electrical crossover. The bass / midrange driver is double coil Kevlar K2 speaker which crosses over mechanically. The conical diaphragm is drien by a voice coil over the entir spectrum to 5000Hz. The second coil is only activated below 250Hz, rather like an engine turo-super-charger, thus boosting bass performance. This ingenious concept results in a linear frequency characteristic of 50Hz to 5000Hz! It also helps to reduce the number of components in the signal path and couple the drive units virtually directly to the power amplifier. Thus, the speaker is able to reveal maximum detail and reproduce the full dynamic power of amusical performance.
