This project born to create an
extreme subwoofer without
a budget limit
to add without problems to any hi-end
In most cases you will only need one subwoofer although someone prefer a symmetrical configuration in a pure audio systems.
As we know it is difficult to locate the subwoofer then in a medium sized room if we place this subwoofer between the speakers we lose nothing of the music track.
Of course we're talking about a subwoofer to be used only in the very low frequencies range below 100 Hz so to be inserted in systems with 5" - 6" mid-woofer.
To get the best
transient response the my choice is a sealed enclosure in a large
box with a Qtc near to 0.5.
Wyntek electronic WAM-300 with DSP
In a domestic environment, it is
quite easy to be able to reduce reflections at the medium-high range
frequencies (see my project
It is much more difficult to operate in the low frequencies range so this project uses a very special plate amplifier that integrates a DSP for digital equalization.
There are very few subwoofer amplifiers using an internal DSP and the WAM300 is probably the only one who can be connected in USB to a PC with Windows in order to change the all the parameters in real time while listening.
The DSP functions allows a perfect adjustment of the low frequency band and some setting can be changed also by a remote command.
The program works very well on Windows PC but in the CD included in the package there is also a version for MAC (still not tested).
Below I have a graph that shows the range of changes that can be achieved with the equalizer and various filters.
With the combination of these two components, Lab 15 and WAM-300, we can be sure of obtaining and dominate the bass in every type of home environment.
Here follows a near filed measurements with and without sealed box equalization.
and here the integration with my Monitor 3 loudspeakers with the bass reflex port closed (near field).
To move this large
loudspekers on my room during the cleaning activity I have used the idea seen on
I have used a base of MDF 25mm and 3 Glisdome with a diameter of 65mm.
