My son wants to buy a subwoofer in the $1K range for music only. He has narrowed it down to these subs-
Rhythmik F12SE, SVS 3000 pro (and a used SVS 4000).
His speakers are the Wharfedale Evo 4.4 https://www.wharfedale.co.uk/evo4-4/
He will probably be crossing the sub over somewhere between 48hz to 60hz.
Right now his system is in my large basement.
I told him that those subs are excellent and that he is probably splitting hairs but I prefer the SVS subs due to the fact that they have a 3 band adjustable parametric equalizer and a phone app that can used to control all the settings. The Rhythmik has a 1 band equalizer and no phone app. The SVS uses a 13" driver vs 12" for the Rhythmik. However, the Rhythmic is servo controlled. Both are non ported.
I told him that both subs will sound great and but I would go with the Rhythmik if he had planar or electrostatic speakers. I feel that having a 3 band parametric equalizer would be better so he could help tune the bass to his room. In addition, if he ever wanted to use it for hometheater he could change the settings with the phone app.
All opinions welcome but please limit it to these subs only. My son wants to get more opinions. He wants a sub that is musical, well controlled and where you can feel it.
