More music enjoyment by an active module

For the 7th time I bought such a module for TV Grawe within 18 months. And am again excited, especially through the digitization of these modules were smaller and lighter, even faint humming transformer belongs to the past. Although this version is missing the high-level inputs and outputs, but an increasing number of amplifiers, even on micro-systems (eg all Yamaha Compact Systems), a separate subwoofer output, whereby the terminal easily. And everyone knows that the supplied speakers are a weak point, since they can hardly emit below 120 Hz. This problem can be such a module in combination with a subwoofer chassis, especially the DIY presents little requirements.
After cutting the boards the closed case with cut-outs and painting was in 24 hours. Created.
For aesthetic reasons, I have recently chosen a sleek casing with 25 L. net which simultaneously as Blumenständer works (H49, B24, T29 cm), this superimposed fitted 20 cm woofers (HECO) with 2 x I - since 8 Ohm - have connected in parallel in order to arrive at 4 ohms. The QTS-factor of the chassis should be greater than 0.5, much more important than the strength! Another bag polyester fleece bolted in the closed housing and the module in the backplane. Finished! Tip for Erstbauer: You build a bass-reflex enclosure, it is difficult to calculate, flow noise often can not be avoided, significantly more volume! Dear less bass, but then the clean and dry. The Volume knob on the module compensates for much, depending on personal tastes. And let's face it: how many times (more rarely) come frequencies around 50 Hz or less in a piece of music before?
Now, for the first time to listen to your favorite music through the system, but the subwoofer off until later. Man, it almost does not believe, as the hearing impression changed positively even at low volume, then louder anyway. Almost always I make the cut-off frequency of 120 Hz, the volume knob to 50 -60%. In short: a real treat!
They are voluntarily subwoofer no longer want to turn off! It does sound better than you would only raise the bass control by 5 dB at amplifier. So from me 5 stars, especially in this module, the price / performance ratio is unbeatable (hopefully will). Thanks to TV Grawe about this offer.
