Today I experimented by adding a subwoofer to my stereo setup. Surprisingly in addition to adding bass, vocals and mids sound more heavy but not so crisp. Turning phase the other way does not affect vocals and mids so much but bass is also lowered. my mind is confused what is happening. Is this normal or something wrong with sub or I am missing something. Sub is supposed to cutoff at 42hz. it is connected directly to power Amp.
Subwoofer affecting vocals?

Hi, Which Sub and what all things in the chain.. Sub integration into stereo is bit tricky.. tweak cross over settings and sub volume to start with.
I'm running a REL sub with KEF R300s with great success. All the best.

Sub - sonus faber gravis domus older model 200w Amp - audiogd master 3/master 1 preamp
Speakers - quad z4.
I also tried with line output from preamp but effect is same. Vocals and mids sound more heavy and different actually maybe more musical but they dont have crispness anymore in high frequencies

Integrating a sub with mains isn't easy. What are your room dimensions and where is your sub placed?
Also, do you have any way of manipulating subwoofer distance in your system?

Bass ( high sub volume or a room mode) might be masking the highs of your speakers.

Turn the volume on the sub all the way down so that the sub gives no output at all. Is the effect that you experience still present?
I tried to do that but i could not hear the effect while volume was all down on the sub. On careful listening i think its about to do with acoustics in the room, the moment i increase the volume, room starts getting filled up with bass and thats affecting soundstage and probably smearing up highs and mids.

Try crossing higher - at or over 55 Hz.
Yes thats same
Let me try same. My speaker specs are
- Frequency response (+/-3dB): 47Hz - 20kHz
- Bass extension (-6dB): 40Hz

This is a good starting point.
Although my desktops have a claimed frequency down to 45, I have tried from 50 to 150 and settled for 100. Best balance in my treated room.

Don't see any high level input on the sub plate amp... how is directly connected to amp?
you see a neutrik xlr connector besides the line inputs? Thats the one for high level
After having some discussion with fm rikhav, I stuck a 2 inch wooden blocks below the foot of the sub. Now its raised and decoupled from floor, affecting vocals less and bass is also more open and better dispersed. I think i will keep it this way for time being.
