SPEAKERS FOR THE AERO
33
The Aero
is a big sounding amp. It is voiced for a sparkling clean sound at low volumes, and

a smooth, dynamic - harmonic overdrive and strong midrange punch. In our opinion, these
characteristics are best complimented with a closed back,

cabinet. Our favorite reference speakers for Komet
amplifiers in general are original coned,
speakers from the 1960's. You may come to a different conclusion,
vintage 12 inch Celestion
depending on your playing style and preferences.
A 2

speaker cabinet lineup is another excellent option. Please see our website

for full speaker cabinet information. Whichever cabinet you do use, make sure you set the
impedance selector correctly. If you use two cabinets, keep in mind that the outputs are in
parallel. This means that if you are operating the amplifier on two, 16 Ohm cabinets, you must
set the amplifier's impedance selector to the 8 Ohm setting. If you operating on two, 8 Ohm
cabinets, set the selector to 4 Ohms. We do not recommend using two, 4 Ohm cabinets. Speaker
wiring diagrams are located at the end of this owner's manual.
An Important Note on Speaker Cables, Cabinets and Speakers: It is crucial that you always
maintain a solid, un-interrupted signal between your amplifier and speaker cabinet. Sub-standard
speaker cables as well as sub-standard cabinet wiring can become problematic, intermittent and
fail over time. This can possibly causing damage to your amplifier and speakers. We recommend
that you use quality brand speaker cables (
to
with quality male
16
18 gauge is sufficient) made
input plugs. The speaker cable plugs should be soldered directly on to the internal speaker cable
wires. Using a quality made speaker cable will ensure a tight fit from the amplifier's speaker
jacks to the speaker cabinet.
Your speaker cabinet should be equipped with a quality brand input jack. We prefer and use the
Switchcraft
#11 mono input on our cabinets, amplifiers and vintage repairs. Many vintage
speaker cabinets from the 1960's to 1970's used the Switchcraft
#11 jack. It is reliable, solid
and time tested. Many modern made brand speaker cabinets use the #11, but not all. Some
manufacturers have their speaker jacks panel mounted on the back of their cabinets which
incorporate an internal circuit board on which the jacks are soldered. This type of system is not
designed for a type #11 jack, and conversion to the #11 can be very tedious. All electrical work
should be performed by a professional and knowledgeable technician.
We also strongly urge you to inspect and make sure that all of your internal speaker cabinet wire
leads are soldered at the speaker jack and soldered at the speaker terminals. We do not
recommend using the
slide on
type gripping speaker wire terminals. These grip type terminals
"
"
loosen over time causing an interruption or failure of the signal. These recommendations help
guarantee a solid, un-interrupted signal from the amplifier to the speakers at all times.
Please note: Komet
Amplification recommends using resistive load attenuation devices in
conjunction with any Komet
amplifier and speaker cabinet. Please see our website
