There are any customers that prefer a subwoofer with some sort of boomy
bass, without perfect bass control and a bass that shakes every fixture in
the listening room.
An uncompromisingly precise bass just doesn't go that low and is also - according
to the design - a bit softer compared to big performers (the law of physics
cannot be ignored).
For those types of customers we have two solutions:
Additionally, the Sub 40 has another remarkable feature:
Should you want to have a small subwoofer with deep and low bass, then this
model may be turned into a bass reflex subwoofer within a few hours using the
parts supplied and changed back into its original state within minutes.
The Sub 40 is designed in such a way that it may be used as a bass reflex
subwoofer with 4 rear bass reflex tubes (distance to the rear wall minimum
10 cm) or as closed subwoofer with extremely precise bass (without bass reflex
tubes or the ports are covered with foam).
It obviously makes sense to use an amplifier boasting state-of-the-art
electronics. For example an amplifier with a digital
sound processor (DSP), like the Hypex Fusion amplifiers,
giving you full control over wanted and unwanted room resonance.
The Sub 40 employs Alcone AC 10 SW4,
drivers with aluminium sandwich diaphragms, showing an excellent finish and
allowing - due to their medium strength magnets - tight control over the diaphragms
but are also just adequate for sealed cabinets.
The Alcone AC 10 SW4 features:
The really strong drive system is rather special. Applying a low tuning, this
driver produces a sound that one would expect only from a much larger cabinet.
This new concept of low tuned subwoofers combined with a strong drive system
is just gaining acceptance in the high-end finished speaker market.
On the rear side you'll notice the Hypex Fusion FA 501 amplifier module with DSP,
giving you full control over the frequency response (pictured above right).
Below you'll find three totally different applications for using this subwoofer:
A) The blue frequency response curve shows the bass reflex subwoofer, also
representing the highest efficiency (with 85 Hz as upper cut-off frequency).
B) The red frequency response curve shows the closed cabinet subwoofer that
C) using the parametric equaliser to the settings as marked in green (HP=20
Hz/24dB, TP=85 Hz/12 dB, Level=3dB, EQ1 = 20Hz/1/+6dB, EQ2 = 45Hz/1/-3dB,
EQ3 = 75Hz/1/-3dB).
It's clearly noticeable that the subwoofer shows totally different sound
characteristics according to the setting chosen. All three sound characteristics
have their own appeal according to room conditions. Their properties we have
