Listening Room & Placement:
High quality stands should be used to bring the tweeter approximately to ear level or slightly above.
Even in the best listening room, it is important to determine the positions where the loudspeakers
will perform optimally. Placing the cabinets too close to the walls or corners will result in more
powerful bass but may also cause response irregularities in the bass/midrange area. Some
experimentation is recommended in order to find cabinet positions that result in a good tonal
balance and freedom from coloration.
After finding a good placement of the speaker, then there are almost endless possibilities to fine
tune the sound balance with the Hypex DSP.
DSP Presets:
Fig 5: The measurements shown in this figure show the frequency response of the different presets
included with the kit, details can be seen in the legend. These presets can provide a starting point for
adventurous DIY’ers
or can be used as supplied with careful placement of the cabinets.
Tips and alternatives:
o
If tweaking with DSP, stay under 9dB gain in the DSP filters to avoid digital clipping.
o
For even more low end-output, the system can be made into a floor standing
speaker by extending the subwoofer enclosure height with 50cm and adding two
SEAS SL26R passive radiators. The subwoofer DSP-filters then needs to be
recalculated.
