LXsub4 provides extremely powerful bass drum strokes, that you may even feel in your chest. A LXsub4 pair is part of the LXstudio system, where it helps LXsirius in the lowest octaves below 60Hz. LXsub4 is the subwoofer of LX521.
LXstudio is 3-way loudspeaker that combines the LXsirius with two LXsub4 dipole subwoofers, which have 10 dB higher output capability than can be obtained from the LXsirius+2 configuration. A 10 dB increase is perceptually significant due to the ear’s very nonlinear hearing sensitivity to the lowest frequencies. With an LR2 crossover at a low 60 Hz the woofers can be placed against the side walls of a room and the LXsirius used as near-field monitors. Path length differences to the listener can be compensated for in the DSP unit. Dipole woofers have the advantage of less room mode excitation, which matters even in a highly damped recording/mixing studio.
The frequency range extends from 25 Hz to 20 kHz. The horizontal and vertical off-axis frequency response, which is heard via the room, is spectrally neutral. Thus, listening off-axis merely changes the viewing angle to the phantom acoustic scene rendered by the seemingly absent loudspeakers.
The LXstudio was designed for a mixing studio application (symphonic music), where the conventional large box monitor loudspeakers gave uneven response, especially at low frequencies, despite the studio being highly damped and relatively large.
The turnkey V-Frame woofers LXsub4 are 33kg each.
To the system -with all woofer drivers installed- usually ships in an airfreight container.
The insurea airfreight rates to the US vary: usually 900-2200€.
If you select the cheaper parcel shipping (4 parcels, limit:30kg each), the upper woofers will ship in an extra parcel and need to be inserted after delivery with 8 bolts and nuts.
