Изучая материал по бытовым колонкам, схожим по конструкции с моими, нашел интересные рекомендации от фирмы Клипш по размещению колонок серии Heritage (
http://www.klipsch.com/na-en/products/heritage/). Несколько аналогичны концертным АС - большой чувствительный басовик + компрессионный титановый драйвер. Другие - полные рупоры.
Может кому-то пригодиться по аналогии...
PLACEMENT
Your Klipsch Heritage loudspeakers will perform well in a variety of locations but best
results will be achieved using the following general guidelines:
• Place on a common wall 6 to 15 feet apart
• Equidistant from the wall behind the speakers
• Heresy: Equidistant height above the floor with the high frequency drivers at seated ear
height if wall or cabinet mounted
• Angled toward the listener and even with or forward of any adjacent obstructions
• Corner or near wall placements provide the greatest amount of bass while increasing
the speakers distance from room boundaries reduces bass energy
• Asymmetrical placement of a pair of speakers from adjacent side walls can smooth
room induced bass unevenness (not adjustable with Klipschorns unless false corners
are used)
• Experiment with the above guidelines to suit your taste and to compensate for your
room’s acoustic characteristics
Klipschorn
Klipschorns typically perform best when positioned in the corners on the long wall of a
rectangular room. If the room is very narrow and long with corners farther apart than 18 to
20 feet, the stereo image may not be optimal. A room with a length to width ratio of 1.00 to
.618 is preferred. In addition, Klipschorn® loudspeakers seem to benefit from ceiling
heights no lower than 8.5 feet.
The Klipschorn® requires corner placement because the walls of the room serve to
complete the speaker’s low frequency horn. To achieve full low frequency extension, the
Klipschorn® should fit tightly in a corner without baseboard or trim interference and the
wall surfaces should extend at least 25 inches beyond the side grilles.
La Scala
The La Scala II features a self-contained, front-firing, folded bass horn to permit placement
out of the corner if required. However, because this model has less bass extension than the
Klipschorn®, the low frequency, acoustic reinforcement of corner placement may be
optimal. The La Scala also offers full flexibility with regard to the amount of toe-in
achievable for the desired stereo image. Deep bass performance may also be augmented
with a high performance Klipsch subwoofer.

Cornwall
The Cornwall III offers the placement and toe-in flexibility of the La Scala with low frequency
extension similar to the Klipschorn at a reduced output capability. As with the La Scala and
Heresy, corner positioning yields the greatest amount of bass output while placements
out of the corner or away from rear walls will yield less bass. Since room acoustics and
personal taste vary we recommend experimenting with several locations to fine tune the
speaker’s performance. Self stick rubber pads are supplied for attachment to the bottom of
the riser for use on hard floors.
Heresy
The Heresy III offers the greatest degree of placement flexibility of all of the Heritage
models due to its relatively compact size. It delivers the same basic frequency range as the
La Scala but at more modest output levels. Corner, floor placement will deliver the highest
degree of low bass reinforcement and the slant riser base helps to compensate for the
Heresy’s short stature. This riser may be removed for shelf or cabinet placement. Self stick
rubber pads are supplied for attachment to the bottom of the cabinet to prevent scratching
of shelves and hard surfaces.
У меня колонки сейчас стоят как раз на полу у длинной стены (не по углам), но наклонены назад как Klipsh Heresy III
Не готов сейчас к большим расходам на аудио после покупки колонок за 8000 гривен. 
на 1 месте акустика + усилитель.
