Setting up a high level signal subwoofer
I wanted to post in the HiFi section as my question is for stereo and a high level signal to a sub and just for music.
I've just kitted up with an Onkyo 509, Mission 733 floorstanders, 75C centre, Mordaunt Short big stand mounted for the rear and my MJ Acousticd Pro 50 mk2 with high level and LFE connections.
It might not be a true HiFi amp or setup, but I think it's amazing and certainly the best musical sound I've ever had.
So for music I already know that I don't want to use the LFE signal, using that sounds attrocious! In 2.1 with a crossover at 90Hz (the crossover could be lower but I don't like the bass of them leading at me when watching TV).
Now I'm trying to setup the high level line for the sub for music in pure 2.0 mode. I listen to drum and bass, the radio and real music like The XX and Coldplay type stuff. I know that the crossover on the sub should be set to around the lowest point my main speakers cut off. In my case my mains go down to 60Hz on paper so my sub setting should be around 60-70Hz. But how do I know the sound is right? And the volume? I know I shouldn't hear the sub, just music, and I think I'm getting there but not sure at all. I hav the volume on the sub almost at its lowest, literally just off minimum! And the higher the crossover I use the less sun volume I feel I need.
Now, should I have like a sub crossover of 90Hz and have some merging of frequencies coming from speakers and sub?
I have the gain around 60Hz and the bass is pretty strong. Around 50Hz and it's a little more pleasant but it might be missing out some frquencies. Maybe im just not aware of true sub bass till now? I guess I just need to find where I like the settings?
Ive used the sub before with some KEF iQ1 small bookshelf speakers and never got it to integrate well. Recently I tried it with my Mordaunt short small bookshelf speakers and my Yamaha micro hifi in the kitchen with the speakers above the cupboards and the bass seemed to sound amazing however i set the sub, on the hard tile floor. Maybe I'm just being critical now as this is my main system?
