Electrostatic Speakers

The Whise®HA1500 is a High Definition - Acoustics loudspeaker that finally combines two ultimate technologies into one integrated full-range solution;
" Balanced PAMSubwoofer technology for a powerful bass experience without any loss of punch or transparency in the low frequencies; and
" Ultra-thin Electrostatic Loudspeaker (ESL) Arrays which break boundaries in physical size, dispersion, loudness (SPL) and transparency, to provide a musical experience with unsurpassed realism.
The advanced subwoofer technology adopts advanced acoustic measures to ensure that the bass/sub bass audio is clear from distortion and vibration. Harmonic distortion is reduced to incredibly low levels, even at full power, combined with an incredibly fast transient response.
Unlike any known ESL system currently on the market, HA1500 combines the use of symmetrically flat electrostatic array with HD-A® mechanical techniques and stylish physical aesthetics. This gives HA1500 its unique ability to reproduce an incredibly realistic presence of the recording environment.
The HA1500's breakthrough technologies ensure frequency consistent dispersion providing a sound stage that is not confined to a sweet spot. An accurate sound image is retained even when moving around the room. This combination ensures a faithful reproduction of low frequencies that blends seamlessly with the transparency of the electrostatic element; promising you an exceptional audio experience.
