Rhythmik F15HP vs FV15HP

Looking for a new subwoofer and I think I’m down to these 2. I watch 70% movies and 30% music. I only have room for 1 subwoofer at this time. I am leaning toward the sealed sub as I do not want boomy bass, I prefer tight, punchy and accurate. My room is 20 ft x 20 ft x 9 ft ceiling height.

Any advice on which way to go? I’ve never had a ported sub before. It’s an expensive decision

Thanks in advance

That is a large room. I would go ported for sure. The Rythmik ported offer clean, articulate bass. I would go with an FV18 if can accommodate budget and size wise....

agree with Ray.

I owned FV15HPs b4.
Very powerful 15" Ported beast with lot of headroom. Dual FV15hp will pressure the room definitely.
It's the KING Legend of 15" Ported subs

For Low + Mid bass slam - Yah will go for Dual FV18s.

One shouldn't consider sealed over ported because of myths. A properly designed and well implemented subwoofer, whether sealed or ported, will result in "tight, punchy and accurate" bass. I'm sure Rhythmik does a great job with designing their sub whether sealed or ported

Large room + mostly movies = ported sub. Servo-controlled Rythmik FV15HP ftw!

I have the sealed F15 Not HP model, I used this exclusively for music only. For movies I use ported subwoofers. If I were to choose one sub only, I would choose the Ported subwoofer as it would be 100% perfect for movies and 90% perfect for music. If I were to choose the sealed sub, I would be getting 100% for music and 50% for movies

It appears based on testing a Rythmik ported sub does not have that issue. I have tried finding good THD data with little luck but from most reviews it appears that Rythmik ported are on par if not slightly better than sealed subs from non-servo sub makers.

Data bass has enough measurements on the FV15HP and fv18 to make your head spin including THD numbers.

Yes they do. I don't really like the low resolution of their graphs, though, as you can't really compare the numbers between subs. It would be nice to be able to extract more detailed numbers from their data or at least have higher resolution graphs, especially above 25Hz.

The other responses get it right - go ported. With the high/mid/low damping option on the FV15HP, you can get the best of both worlds in a single unit. This FAQ link might also help.
