A low power OTL will be about 15
watts into 8 ohms. Power will increase to 25 watts into 16 ohms. At 4 ohms the
power will be 7 to 10 watts.
OTL and tube power amplifiers best friend.
REALITY HS (High Sensitivity) has been special developed to support OTL and tube
power amplifiers (winther period 2000 - 2001).
REALITY HS has a high sensitivity and a very high impedance. 10 watt
single-ended tube amplifier or a 10 watt OTL amplifier is enough to power this
loudspeaker and drive it to high listening levels.
Listening tests have verified the musicality and speed of this loudspeaker. The
REALITY HS has a smooth, wide and open three-dimensional soundstage. The
listener can really feel the depth in the music. The bass becomes better when
using a tube amplifier to power the REALITY HS loudspeaker than a Solid State
Amplifier. The answer it the very high impedance in the bass area, which is
minimum 16 ohm, and therefore the tube amplifier only have to deliver a small
current to drive the bass.
Several tube amplifiers have auditable distortion when using when using 4 or 8
ohms loudspeakers. The audible distortion will be reduced when using the 16 ohm
REALITY HS loudspeaker.

REALITY HS can be combined with the sub-modules, if the SUB-modules are powered
by an external Solid State amplifier or the build-in ICEpower amplifiers. As
many know OTL and tube amplifiers do like loudspeakers with a high impedance and
a high sensitivity. Tube amplifiers will love the REALITY HS while a Solid State
amplifier or the build-in ICEpower amplifiers can be left to power the
SUB-modules.
The cabinet of the REALITY HS loudspeaker is the same as the REALITY 3D
loudspeaker (the technology platform) and therefore having the same acoustical
features as the REALITY 3D cabinet.
The PHL 1240 bass unit from France is an expensive handcrafted precision build
driver normally only used in professional loudspeakers used in recording
studios. The sensitivity of this unit is 92dB and the impedance is 16 ohm. It
has phase plug too.
The sweet sounding tweeter: It is of course a superb tweeter from Scan Speak. It
do match the high sensitivity and the impedance of the bass unit. It is a wide
dispersion design and therefore no horn sound. It is an expensive and very good
tweeter used in many high-end designs.
The printed circuit boards of the REALITY 3D crossover are
used in the REALITY HS loudspeaker. The main difference of the two crossovers
are value of the components, because the crossover frequency and the impedance
are different. The high quality components have a very small loss to keep the
sensitivity of the units as high as possible. Acoustical Linkwitz Riley slopes
ensure the acoustical phase is very precise. The crossover frequency is 1500Hz,
which is a perfect point. The resonance frequency of the tweeter is completely
removed and therefore the REALITY HS has a very LOW acoustical distortion.
