DB Technologies Sigma S118

Craig C., 18.11.2013
So I have now had the Sigma speakers for 9 months, doing a least two gigs a month. I have paired the s118 with the s115 to give a full sound with plenty of sub bass.The rig is being run with a Behringer x32 mixer
First of all, these things are a little heavy so I move them on dollies to save my back, secondly because the speakers are heavy, you will soon be touching up the cabs with a black pen, so covers might be an option.
Now the most important bit, the sound, these speakers can give a great sound with amazing highs and mid range from the S115 and deep sub from the s118. Every band I have worked with these speakers has gone, that sounds great and have been complimented by the audience. Good sound for 500 people with out pushing them to max volume, and in smaller venues it can fill the whole room with rich sound. In a small venue (100 people) I found turning the subs down and let the S115 work instead.

I bought a pair of Sigma S118 as a living room subwoofer. The first impression, regarding the optics, was good.
The trapezoid-shaped housings fit well with my Flexsys F-315 boxes, which now only function as tops.
For the special purpose of use at home I have removed the front hole grid.
In the case, a chassis with a steel sheet basket performs its function. On the other hand, in the operating instructions for the Sigma boxes at least in the context of the sub of an "Alukorb" ...

The plywood surfaces of the box housing are properly protected with textured lacquer. Only with the surfaces of the front panel and the reflex port, which are normally not visible behind the front grille, I had to rework. "Warnex Structure Paint Black" has proven its worth.

The housing is stiffened in the interior with various struts and does not tend to resonate.
After sufficient recording time of the S118 I would like to classify their sound as comparatively "warm and full". Nevertheless, impulses such as kickbasses are reproduced correctly.
The volume regulator should be adjusted carefully and to the efficiency of the used top parts. There is sampling. There is no latching position of the controller or any printed amplification indications as indications for setting.
The power amplifier modules work reliably. With the 80Hz setting of the transition frequency one is well served. The top parts are very clearly relieved of the low bass with advantages for sound and resilience ...
