Notwithstanding my criticisms of current surround sound technologies and the psycho-acoustics of the perception of the acoustic-holographic focal point, surround sound, as with previous attempts in the past, is an attempt of creating the full ambience of the original performance. Though the technology now is better than the original attempts in the past; my bias is still strongly weighted to a proper stereo setup.
When seeking a sub-woofer laws of physics deem that if you want 'bass' the working relationships between the loudspeaker transducer and its enclosure is that the enclosure needs to be large. Bass frequency is composed of long-wavelength signals and this is best reproduced by larger diameter loudspeaker transducers in correspondingly large enclosures.
For this reason it is recommended that one of the Panda Model 15's be used as your front main speakers. Their inclusion of 2 X 15 inch woofers with separate binding posts from the other transducers, allows for the provision of either directly amplifying from your current surround sound amplifier or to have a separate sub-woofer amplifier for the bass.
There are any number of combinations that will create excellent reproduction of surround sound. Avoid placement of loudspeaker transducers in the wall and ceiling. Use only fully designed enclosures. Discrete enclosures have all been individually designed to be accurate producers audio. It takes a considerable amount of time to design, test and produce a loudspeaker. Additionally the post-production final testing at the manufacturing venue ensures that the consumer is receiving a quality product and that the performance is up to the manufacturers standards ( which vary from manufacturer to manufacturer ). If you are seeking high-fidelity then the judicial placement of discrete loudspeaker enclosures will deliver the best result. Aim all loudspeakers to your listening position.
The Panda Model 15 loudspeakers
are ideal as the front main speakers for any surround sound system.
This being because of the large 15 inch woofer which can be powered
by a separate sub-woofer amplifier or with your current surround sound
amplifier.
The effects loudspeakers, the Panda Model 3g, are a D'Apollito
alignment smarting M22 Monopoles® and internally wired with linear
crystal copper. These speakers are supplied with heavy duty brackets
for mounting them on the walls of your listening room.
With some Amplifiers, such as the Yamaha DSP-AX1, have provision
for two additional loudspeakers for additional front effects or the
Denon AVC-A1SE Surround amp which have provision for di-pole cinema effects
loudspeakers. The Panda Model 3h is such a loudspeaker.
Where this is the case please specify and if for the Yamaha additional
standard surround speakers are provided and for the Onkyo or Denon a di-pole
version is available.
Both The Panda Model 3g and 3h are internally wired with linear
crystal copper.
Amplification.
There are many surround sound pre-amps on the
market today as well as many fully integrated surround amplifiers. These
also have the surround sound decoding chips included within. As you go
up the price escalator it pays to invest in a quality surround sound pre-amplifier
and singular monobloc power amplifiers for each loudspeaker.
Surround Sound Amplifiers recommended are:
Yamaha DSP-AX1
Denon AVC-A1SE
These can also be used as just pre-amps and power amps can then be used from there to gain better audio signal quality.
It is impossible to modify the integrated amps to accommodate either TomCatsTM or MinMin-LightsTM. Their RCA's are at 12.7 mm centres ( half inch ) and their binding posts are invariably the press-fit variety. Accordingly many surround sound pre-amps also have their RCA chassis receptors at close spacing and this makes it difficult to upgrade these to a better quality component.
Modifying Monoblocs to accommodate Monopoles®, TomCatsTM or MinMin-LightsTM is easier.
Valve amplification will deliver a better acoustic-holographic imaging while conventional transistor amplification will deliver more wallop. There are no valve surround sound pre-amplifiers due to the requirement of integrated circuits for the processing of the surround sound signal. Some valve surround sound pre-amps utilize valves in other parts of the circuit.
Utilizing Pandas.
With either of the Model 10 and 15 there is no need to have a sub-woofer as these loudspeakers will deliver full bass and optimal acoustic-holographic-imaging.
