Designers Notes on setting up speakers and room position
ü The speaker spacing, location and distance to the listener are critical in enabling the optimum sound
best position for the HDS series L&R speaker is from 2.4M apart to 2.54M
apart standard when located parallel to rear wall for medium size rooms
(3x 4)M and (4 x 5)M
And up to 4M apart can be used with large rectangular rooms (6 x 9) Mtrs
Use masking tape on the
floor around the base of the speaker to mark the
box position as a reference point for position adjustments.
ü Amplifier Left & Right Channel level (balance) will effect everything
ü Set Left & Right Channel volume level (balance) by ear or by level meter using a pink or white noise test tone generated in your Hometheatre receiver or with stereo amplifiers using a noise test tone from a CD/DVD disc . Do all level tests & positioning tests whilst seated in the centre listening position (lay back lenny lounge chair).
Important Note :
You need to re check and reset the Amplifier Left & Right Channel level
(balance) each time you move the speaker position OR change the program sound source
HDS series speakers were designed for medium to large rooms with a nominal
seating distance of 3.7M, but can be also used in small rooms and flats as well
ü The closer you get to the rear or adjacent walls then the more "bass boom" you will get and LF room refraction increases.
tile or suspended wood Floors, I recommend adding a piece of 12mm thick Grey
Furniture removalists felt underneath each speaker box the size of its base.
This also makes positioning speakers a breeze.
speakers out from the rear or adjacent walls will reduce the lower bass end and
lift the mid and top end balance (like a see saw effect).
This means you will get tighter bass transients the further out into the room you move the speakers.
ü The shorter the listening distance to the speakers the more you will need to rotate or toe the speakers outwards
ü The closer you get to the speaker the more this affects the on and off axis listening experience and thus affects the depth of field, Bass, Hf & mid balance
ü Gradually Toeing the Speakers outwards from your centre sweet spot so they are parallel to the back wall will reduce HF & mids.
ü As you appreciate, there are many variables in acoustics and the room environment is a huge variable.
ü Remember like a motor car all speakers need to be run in over at least 2 months or 50 to 100 hrs
ü One-step at a time lads will achieve a lot.
ü In addition, may be its time to consider upgrading your speaker cable, equipment & interconnects which will enable the speakers to provide even more detail& dynamics to your listening experience.
