Hi, I have active speakers Q acoustic M20 HD and streamer Wiim Pro, everything is ok but I missed deeper bass. I have an unused passive DIY subwoofer kit at home. I decided to buy
DTA-100LF Desktop Subwoofer Amplifier with EQ which has an input sensitivity of 200 mV and use the sub out on Q acoustic M20 HD but I found out that the output voltage is only 380 mV depending on the volume of the speakers, the subwoofer is very quiet even with different settings. I want to ask if a Wiim Utra streamer with sub out and full setup management and better Vrms would solve this problem for me or buy a simple preamp like the Fosi Audio P4? Just for information, I did a blind test using a Pro-Ject CD Box DS3 CD player, used an RCA cable to the DTA-100 LF and the difference is clear. The CD player has a constant 2 Vrms if I'm not mistaken. Thank you for your answer and I wish you many musical experiences.
