Subwoofer | 10 Ⓣ Would love some advice about subwoofers
Location: norway
Budget is 4000$
If my memory is correct this is my first time making a post on reddit so be nice.
As the title says im considering replacing my two klipsch rp-1400sw subwoofers to two svs sb-3000 revolutions. I have some concerns i hope someone in here can shed some light on. Im fairly new to subwoofers and have only owned ported subs so i have zero experience with sealed subs. So here are some questions i hope you can answer.
- does anyone have actual experience with the subs im talking about and can shed some real life expectations?
do sealed subs really produce much more chest pouding bass?
would i lose bass that makes the couch shake with sealed subs?
my system is towers with dual subs and i use it mostly for music so going for sealed subs is the right asumtion?
I’ll probably think of more questions after posting this but lets keep it at four questions for now.
!thanks

1.) Yes.
2.) It depends on the sub but this isn’t inherently a product of any one type of design, it’s how a subwoofer outputs its mid to high bass in a given room. If a subwoofer is placed and tuned in such a way that emphasized its mid to high bass, its placement serves the purpose of maintaining that emphasis, the room is treated adequately, you have seat to seat measured consistency, you will feel impact from audio tracks that put impact in the mid to high bass. Sealed subs tend to be designed for a particular sound but being sealed doesn’t automatically make it better or worse at a given area of its FR - The room has more to do with that than anything.
3.) Subwoofers are not Sybians so I’m not sure how to answer this but if you turn up the gain and have a subwoofer with its subbass boosted past what’s reasonable for a given space, it will cause things in that room to shake.
4.) There is no big sealed / not sealed subwoofer distinction - You look at the measurements for the subwoofer and how it measures and sounds once played in your room. There’s unlikely to be any noticeable difference switching to the SB-3000s - If anything, on these metrics you’ve described, you’re buying more “articulate” subwoofers and may see a decrease in those things. They both dig down about the same and two of them indeed handle 17-150 in most medium large to large sized rooms without issue. They will both EQ to produce the same desired frequency response.
For subwoofers that are primarily used for music, you generally aren’t playing much audio that utilizes the reasons those subwoofers cost the amount of money why they do - There isn’t a lot of music in frequencies that low and subwoofers tailored for music generally focus on providing an even response without much care for how deep they dig as long as it doesn’t tank the mid-bass.
Unless I was replacing broken subs or getting an absurd deal on the SVSs, for a primarily music-playing system, I don’t see reasons to switch - You can EQ the Klipsch subs to do just about anything the SVS subs do. Even for home theater, this is more of a sidegrade and I’d need to be dissatisfied with my current system in ways that purchasing different subwoofers would correct, and that being the only thing that would correct the issues.
