Subwoofer opinions needed
« on: 26 Jan 2021, 06:55 pm »
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

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.

You and your son should be aware of inherent in-room bass peaks/dips that can reach 30 dB!  Using of a single subwoofer or lining up one/two subwoofers along the line of the main loudspeakers exasperates the phenomena.  The best solution is carefully located multiple subwoofers.  Floyd Toole, in the 3rd edition of his book "Sound Reproduction" recommends 4 subwoofers located either in the corners or midway along each wall.  Try elevating one and/or connecting one out of phase.  Take a look at "swarm". 

One sub can only add special effects rumble and boom.  For that just add any subwoofer that goes deep, louder for larger spaces.  I use (3) 10 inch carefully placed subwoofers in my audio room and a single used 15 inch subwoofer in my modest A/V system.  No need to spend $1000.  Most would suggest a sealed subwoofer for music, ported for A/V use.

I've been using my SB3000 for close to a year now and love it. Before purchasing I looked at Rythmik, HSU and a couple other sealed subs. I can't recall exactly what sold me on the SVS, but I'm glad I did. Aside from the sound, which never ceases to thrill me, the remote app is the biggest selling point over the other subs. It's one of those things that once you experience, it's hard to imagine living without it.

Being able to fine tune the sub without getting up and down, over and over, is invaluable to me. Also, not all recordings are EQd equally, and being able to dial the sub up or down instantly to accommodate is indispensable. I'll never own a sub without it.

Agree with others. I have 2 tiny reps that once I moved from behind the speakers to a position perpendicular to them, I got much better bass. Neighbors are happier too. As I’ve discovered in this hobby, it’s not the gear so much as the setup. A lot of people of upgrade bc they don’t see the options of working with what they have. I’ve been guilty too.

Thanks for the replies.  My son's plan is to eventually go with dual subs.  I run dual subs and he has heard the difference.  He has also heard the difference between cheap subs and more expensive ones.  He is considering 2 of the cheaper offerings from Rhythmik.  They make a $500 sub that is sealed and servo controlled that has good reviews.  He could buy 2 of them. 

I agree that a swarm of subs is the way to go but you have to have the money and space.  Eventually when he gets his own place he will not have the amount of room that my basement has.

I will post his decision when he purchases a sub.

My son purchased the Rythmik F12se after talking with a guy from Rythmik.  Will report back on it after its broken in.
