simpel maar effectief
eerste keer dat ik zo'n speakertester gebruik, maar het doet prima wat het moet doen. zo ben ik erachter gekomen dat ik 2 tweeters moest vervangen van mijn monitors die het niet meer goed deden. heel handig voor als je twijfelt of alles nog wel goed werkt.

Nice device, but needs some tweaking
In principle it is a nice, simple effective device. However, upon arrival the frequency range was way off the scaling: at 100 Hz setting a minimum of 16 Hz, below that no output at all, and a maximum frequency of 16 kHz at 20 kHz setting.
In order to solve this, I decided to open the signal generator, obviously voiding the warranty. I found that there is a small trimpotmeter which presets the frequency range, and after some tweaking I came to 19.5 Hz to 23 kHz. The output level is quite constant over the complete frequency range. Nice!
So for those facing an incorrect frequency range: it can be solved without much effort.
For perfectionists: replace the trimpotmeter by a multiturn one...
