#01 Can the LS-1000 be used without subwoofers?
Four LS-1000 modules have a frequency range down to 100Hz, therefore a boundary woofer or subwoofer will be required. If there is no need for a very high output level, the LS-1000 may be used without subwoofers by extending the frequency response down to 40 – 50 Hz using equalizing in the processor.
#02 How many LS-1000 modules are required?
The principle of a line source with less sound reflections from floor and ceiling and a consistent volume level across
the room can only be achieved by a sufficient number of speakers forming a tall line array. Four LS-1000 modules in a floor-standing stack are recommended. Due to the high directivity of a line source speaker, the optimal listening height is at the center point of the speaker stack, and 60 cm / 2ft above and below. If the listening room has tiered seating, the stack should be increased to five LS-1000 modules.
#03 Can the LS-1000 Center be used as left and right speakers?
Yes, if there are no nearby left and right sidewalls, three LS-1000 Center speakers achieve a wider sound dispersion into the room, allowing a very wide seat layout.
#04 Can the LS-1000 Left or Right also be used as a center speaker?
Due to the inwards-beaming sound radiation of the LS-1000 Left and Right speakers, they must not be used as a Center speaker in the middle of the screen. The sound field would not match the left and right front speakers, and the sound image would become very uneven across all seats.
#05 Can the LS-1000 Center be placed horizontally?
The LS speakers are designed and tuned as upright line source speakers with a very linear sound radiation. This linear sound radiation must not be turned 90 degrees. The sound field would not match the left and right front speakers, and the sound image would become very uneven across all seats.
#06 Which speaker size should be set in the MP-40 / MP-50 / MP-60 menu?
A line array of four LS-1000 modules has a frequency range down to 100Hz (-3dB). The recommended setting is XS. Even though the LS-1000 could reproduce frequencies down to 50Hz, the XS setting lets the LS-1000 roll off around 120Hz and play effortlessly within its ideal frequency range. The speaker EQ must be set to Lyngdorf LS-1000.
For this set-up we recommend a minimum of one left and one right BW-20 woofer to handle both the LFE signal as well as the redirected bass from each LS-1000. More BW-20 might be required depending on the room size, room acoustics, and desired maximum volume level. The recommended setting for the BW-20 is SUB_400, so that it will cover all the bass.
