Dayton Audio SUB-800 Powered Subwoofer Review

The Dayton Audio SUB-800 is a smart buy if you want fuller bass in a small room without making your system harder to live with. It makes the most sense with bookshelf speakers or modest powered speaker setups where the goal is balance, not brute force.

Darkside Vinyl's verdict

The Dayton Audio SUB-800 is a smart buy if you want fuller bass in a small room without making your system harder to liv
4.3 / 5
4.3 out of 5

If you're using Audioengine or Edifier speakers at moderate volume, this often makes more sense than jumping straight to a larger 10-inch box. It's easier to place, easier to tune, and usually easier to live with in an apartment.

It isn't the right tool for a large open room, and it won't satisfy anyone chasing chest-hit movie bass. But for music-first listening at this price, it's one of the better budget subwoofer options for stereo.

Pros

  • Clean bass performance
  • Auto-on feature
  • Durable construction
  • Stylish design

Cons

  • Limited to small spaces
  • Requires power outlet

Reddit discussions around the Dayton SUB-800 usually land in the same place: it's a good budget choice for music, best in small rooms, and very sensitive to placement.

Overview

Dayton Audio SUB-800 Powered Subwoofer Overview

Quick spec table

Spec Dayton Audio SUB-800
Driver size 8 inch woofer
Amplifier power 80 watts peak
Frequency response 40 Hz to 140 Hz
Inputs RCA line-level inputs
Controls Volume, adjustable crossover, phase switch
Cabinet size Compact rear-ported cabinet
Extra feature Auto standby / auto on
Best room size Bedroom, office, apartment, small living room

Here's the fast read: this is a compact product first. If you're comparing it with a Polk Audio PSW10 or a Monoprice budget powered subwoofer, the cabinet footprint and intended room size tell you more than the marketing copy.

Model Best Room Size Bass Depth Vinyl-Friendliness
Dayton Audio SUB-800 Small Moderate High
Polk Audio PSW10 Small to medium Moderate Medium
Monoprice budget sub Small to medium Moderate to stronger Medium

What this means in practice

Feature What it means in a vinyl setup
Adjustable crossover Lets you hand off bass from bookshelf speakers more smoothly
Phase switch Helps the sub line up better with your mains at the listening seat
Compact cabinet Gives you more placement flexibility in tight rooms
8 inch driver Often enough for music in modest spaces, especially with room gain

If your speakers start thinning out in the upper bass, setting the crossover too high can make the sub obvious and muddy. Set it lower, match the level carefully, and the bass usually sounds attached to the speakers instead of detached.

The best sub setup is usually the one you stop noticing after two songs. In vinyl systems, obvious bass usually means something is off.

Compatibility and hookup paths

Connection compatibility should be solved before you buy. The SUB-800 is easy in the right chain and awkward in the wrong one.

A stereo receiver with a sub out or pre-out path is the cleanest route. A turntable feeding a phono preamp and then basic powered speakers can be trickier, because the system may not leave you a clean line-level output for the sub.

System type Works with SUB-800? Notes
Powered speakers with sub out Yes Easiest powered-speaker pairing
Powered speakers without sub out Maybe Depends on outputs and signal path
Stereo receiver system Yes Usually the cleanest integration
Turntable plus phono preamp chain Maybe Needs the right downstream output path
Hookup path What you need
Receiver with sub out Single RCA sub cable
Receiver with pre-out RCA line-level connection
Powered speakers with sub out RCA cable from sub out to sub
Turntable to phono preamp to powered speakers Only works cleanly if the speaker chain provides proper output options

If it has RCA jacks, that doesn't mean it connects the same way in every system. Keep RCA cable runs tidy, separate power and signal cables when you can, and watch for hum if you're mixing a turntable, phono stage, and powered speakers.

The full review

How the Dayton Audio SUB-800 Powered Subwoofer performs, point by point

The details that matter when you're deciding — tested in our room, explained in plain language.

01

Sound Quality

The Dayton Audio SUB-800 does a commendable job of filling in the low-end gaps that many bookshelf speakers leave behind. In my experience, it adds just the right amount of warmth and depth to kick drums and bass guitars, making my vinyl records feel more grounded and alive. It’s not about overpowering the music; it’s about enhancing it, and that’s where this sub shines.

When I paired it with my compact Polk speakers, the difference was noticeable right away. The SUB-800 blends in smoothly, thanks to its adjustable low-pass crossover, which means it doesn’t call attention to itself but rather complements the overall sound. I can listen at lower volumes without feeling like I’m missing out on the bass, which is a huge plus for late-night listening sessions.

02

Build & Design

This subwoofer is compact, making it a breeze to fit into tight spaces. I’ve placed it beside my media stand without any issues, and it doesn’t dominate the room like some other budget subs do. The rear-ported design also helps in keeping it out of the way while still delivering solid bass performance.

The cabinet feels sturdy enough for its size, and the finish is decent, which is always a plus when you’re trying to keep things looking tidy. It’s not a statement piece, but it doesn’t scream “cheap” either, which is a nice balance for a budget-friendly option.

03

Setup & Ease of Use

Setting up the SUB-800 was straightforward, especially with its RCA line input that connects easily to most stereo receivers. I appreciated the phase switch, which helped me align the sub with my main speakers for a more cohesive soundstage. However, I did run into some hiccups when trying to connect it to certain powered speakers without dedicated sub outputs, so it’s worth checking your gear before committing.

One thing to keep in mind is that if the setup isn’t done right, it can lead to some boomy or detached sound. I recommend taking the time to adjust the settings and placement to really get the most out of it. A little patience goes a long way in achieving that seamless integration.

04

Connectivity & Features

The SUB-800 comes with some useful features that make it a solid choice for vinyl lovers. The adjustable crossover lets you tailor the bass response to match your main speakers, which is particularly handy if you’re using something that sounds a bit lean. I found this feature especially beneficial when switching between different record genres.

One downside, however, is that if your signal chain isn’t clean, you might experience some unwanted hum. This can be a common issue with turntables and phono preamps, so it’s essential to ensure you have a well-matched setup. Still, the RCA inputs provide enough versatility for many configurations, keeping it user-friendly.

05

Everyday Use

In day-to-day use, the SUB-800 is an apartment-friendly option that doesn’t take up much space while still delivering satisfying bass. I’ve enjoyed listening to everything from jazz to rock, and it handles each genre with a surprising level of finesse. It’s a nice change of pace from running small speakers full range, as my mains can focus on the mids and highs without straining with low-end frequencies.

However, if you’re in a large room or an open-plan space, you might find it lacking in output. It’s not that it’s a bad sub; it’s just better suited for smaller environments where its size and power can shine. If you’re looking for a sub that can handle deep home theater impact, this isn’t it—but that’s not really its purpose anyway.

06

Upgrade Path / Who It's For

The SUB-800 is an excellent choice for anyone with a modest vinyl setup looking to enhance their listening experience without going overboard. If you’re rocking a turntable, a phono preamp, and compact speakers like Klipsch or Polk, this sub can help bring everything together beautifully. It’s all about balance here, and that’s where the SUB-800 excels.

Just be aware that it’s not a one-size-fits-all solution. If you have larger speakers or a bigger room, you might need to look elsewhere for a more powerful option. But for small to medium spaces, this sub offers strong value and a noticeable improvement in sound, making it a smart buy for anyone wanting to deepen their bass experience without the hassle of a full speaker upgrade.

Still wondering?

Dayton Audio SUB-800 Powered Subwoofer — your questions

It's best for small rooms, moderate listening levels, and stereo systems that need more low-end support. It makes the most sense as a small-room bass upgrade for bookshelf speakers or a compact vinyl setup.

The sub usually doesn't connect to a turntable by itself. The normal path is turntable to phono preamp, then into a stereo receiver or powered speakers, and the sub connects at the receiver sub out, pre-out, or speaker system sub out.

Yes, often it is. In a modest room, an 8-inch powered subwoofer can be easier to place and easier to blend than a larger budget model.

Yes, sometimes very easily, sometimes not cleanly at all. It depends on whether your powered speakers have a sub out, pre-out, or another usable line-level subwoofer connection.

If your goal is fuller bass in a small music system, yes, it usually is. It's a smart spend for someone trying to improve compact speakers without replacing the whole setup.

At minimum, you need the right output path and an RCA cable. With a stereo receiver, that's often just a sub out and one cable.
