just finished my new pyramid boombox equipped with:
- 1 Sub TANG BAND W5-1138SMF
- 2 passive DAYTON AUDIO DSA115-PR
- 1 medium Monacor MSH-116
- 1 ribbon tweeter FOUNTEK NEO CD 3.5H
- 1 Arylic Amp 2.1
The objective was to get strong bass and original design with a pyramid (base:25cm, height:70 cm). I struggled a bit with the wood cutting as most of the angles are not 90 degrees…
The small 5 inch sub plus the 2 passive speakers on the sides generates a impressive bass for such a small volume.
Very happy by the resulting sound and the clean bass from the amp 2.1 even at high volume.
I also used the ACP Workbench in order to set filters, with the medium on the right channel and tweeter on the left one, with a cut frequency at 3k5.
The result of this setup is obviously mono, but on such boombox, the left and right speakers are so close that you don’t get a good stereo effect anyhow.
Note that with ACP Workbench I set the output as the Left+Right input.
And the active filter is far more flexible than a passive filter for the tuning to the speakers tone.
with the ADC key I have configured 3 different Equalisation selected with buttons on the back: a loudness Eq to listen at low volume, a normal, and a Eq to boost the bass.
