Vienna Acoustics Bach User Manual

CABINETS
Our speaker designs feature massive and inert cabinet
construction. Vienna Acoustics cabinets are designed with the
latest computer modelling techniques and use a combination
of amorphous materials in order to ensure that they are both
stiff and well damped. Additionally, our designs feature narrow
front baffles in order to promote accurate imaging. The
combination of precise build construction using furniture grade
finishing techniques and complex internal damping produce
designs capable of accurately rendering music.
CONNECTIONS
The massive Vienna Acoustics input terminals are designed to
accept banana plugs, spade terminals or bare wire connec-
tion. Make certain that all connections are well tightened
since poor contact between speaker cable and input
connector can lead to degradation of sound quality.
It is also a good idea to make a point of regularly cleaning all
connections in your system since oxidation will build up on a
regular basis. We use gold plated terminals which do not
oxidize, but contaminants or surface build-up on your spea-
ker cables and connectors may degrade sound quality.
While it is popular among some audiophile circles to fit
duplicate sets of binding posts for "bi-wiring", we have cho-
sen to follow sound engineering practises. Our crossovers are
configured as an organic whole, intended to optimize every
known aspect of driver integration.
It is our belief that with the high quality of wire currently
available, it is in most cases possible to obtain higher
performance from a single run of superior cable to two lesser
runs of cable. By keeping a single ground plane in our

Summary

Cabinets

Connections

Connection Terminals

Vienna Acoustics terminals accept banana plugs, spade terminals, or bare wire. Ensure tight connections for optimal sound quality.

Connection Maintenance

Regularly clean connections to prevent oxidation. Contaminants on speaker cables or connectors can degrade sound.

Bi-wiring Philosophy

Company avoids bi-wiring, preferring superior single cables for better control and performance in crossover design.

Cabling Recommendations

Amplifier Synergy

Amplifier Type and Selection

Speakers are compatible with solid state or tube amplifiers. Careful selection of quality electronics is essential for full system potential.

Wattage and Sound Quality

Amplifier wattage is less critical than sound quality. Low wattage amps stressed beyond limits can cause distortion damaging speakers.

Loudspeaker Break-in

Speaker Positioning Guide

Free Air Placement

Place speakers at least 1 meter from the rear wall. Adjust position for balance; rear wall distance affects bass and depth.

Near Wall Placement

Speakers can be placed close to a rear wall. Requires less toe-in; small movements are critical for optimal sound quality.

Speaker Spacing and Toe-In

Position speakers 70% of room width apart. Adjust spacing and toe-in to achieve a unified stereo image and avoid sonic artifacts.

Toe-In Effects

Angling speakers inward (toe-in) reduces sidewall reflections, resulting in a smoother, warmer, and more focused sound.

Room Treatment

Optional Sandfilling

Maintenance and Care

Cabinet Cleaning

Clean cabinets with a soft, damp cloth. Avoid direct sunlight and heat. Use a soft brush for woofers.

Tweeter Cleaning Warning

Never attempt to clean dust from the tweeter, as this will damage the delicate silk domes.
