So, if you are here, you are obviously interested in subwoofers or want to buy such a device. Among the models on the market, there are 2 main types: active and passive. The main difference between an active and passive subwoofer is the built-in amplifier. The active ones have it, and the passive ones do not. Nevertheless, it is the passive subwoofers that can produce better sound. So how to find the best passive subwoofer? And that’s where I and my review on this topic will help you. But first, a little bit about the technology itself.
The passive subwoofer is a classic because the original form was already built that way. The subwoofer itself has only one diaphragm and generates no power. That power comes from the power amplifier. So the power amplifier needs both the power and the input from the speakers. That’s why a passive home subwoofer would be a great addition to your home theater system. Get ready-we’re getting to the fun part!

Electro-Voice ELX200-18S – premium
Electro-Voice company – a widely known American manufacturer of professional audio equipment has released for sale quite an interesting series of versatile speakers, ELX200. This lineup includes five models, and ELX200-18S is among them. This model is considered a premium class, and the appearance, as well as the components used, immediately confirm it.
The manufacturer claims all components are custom-made, have passed the necessary tests, and far exceed industry standards. I don’t undertake to confirm or deny this, but the full-range composite case looks very sturdy and stylish, and all of its components are indeed made with quality. Device dimensions (H x W x D): 23.62″ x 19.96″ x 22.6″, and note that it is heavy at 58.64 lbs.
The integrated proprietary Class D power amplifiers using high-sensitivity transducers really deliver maximum sound pressure levels without distortion. Its power output (continuous/peak) is 400W/1600W; its nominal impedance is 8Ω. Having tested it, I can say that it is a well-balanced sub, very clear and accurate, which provides full bass. The ELX200-18S is just perfect for listening to music.
To summarize, I can say that this is really a quality top-level subwoofer, which, if properly tuned, will give you a cool sound experience and, even with regular use, will last for many years.
- Power (RMS), W: 440.
- Driver size, inch: 18.

Behringer Eurolive VP1800S
The next model is representative of the budget range EUROLIVE. This Behringer VP1800S passive subwoofer features an 18″ driver capable of handling up to 1600 watts (peak) at 8 ohms. Its phase-inverter case is designed with frequent subwoofer transportation in mind. It has handles, rubber feet for stability on different surfaces, and a special speaker stand for co-mounting with wide-band speakers from the same series. Keep in mind that it is better to carry VP1800S by two people since its weight is 91.3 lbs, and its dimensions (H x W x D) are 20.9″ x 25.6″ x 24.2″.
This model has an 18″ bass driver that operates in the frequency range of 35 – 250 Hz and delivers 100dB of sound at 400W (1600W – peak). On the back of the case is a slightly recessed patch panel consisting of two Neutrik Speakon NL-4 connectors (IN/THRU). When using a separate crossover or low-pass filter, the THRU connector allows the filtered signal to be sent to high-frequency speakers, which saves amplifier channels and cabling for switching. In addition, the front side features phase inverter openings and a removable grille enclosed by a protective grille, which provides good sound directivity.
As for the sound, the bass is quite loud, tight, and precise, without rattle or resonances. I tested the VP1800S with different amplifiers. It worked quite well with 500-600 watts of power, but I didn’t test a heavier load.
Maybe the VP1800S doesn’t produce audiophile sound, but you have to pay for that quality. And in this case, for not much money, you get a good “workhorse” which is quite suitable for many users.
- Power (RMS), W: 400.
- Driver size, inch: 18.
- Frequency response: 40Hz-200Hz.
- Dimensions, inch (HxWxD): 20.9×25.6×24.2.
- Precise reproduction of ultra-low frequencies with a clear, powerful punch.
- Rugged steel grille to protect the speakers.
- Accurate and tight bass.
- Handles are not comfortable to carry.
- Quite heavy.
- Cabinet construction is not of great quality.
Advantages of passive home subwoofers
Unlike an active subwoofer, a passive subwoofer works more like a conventional loudspeaker. A crossover defines the frequencies that it outputs. The passive subwoofer has the main advantage that the power amplifier works independently of the actual subwoofer, and the device is, therefore, less prone to interference.
Not only the best passive subwoofers but also standard devices with this technology offer the following set of advantages:
- With a passive subwoofer, the bass is relieved of the other speakers.
- It has more power and plays a stronger bass.
- No hum or clicking side sounds and noises.
- Mainly covers the low frequencies.
- A passive subwoofer is compatible with a lot of different devices.
- The power amplifier and unpowered subwoofer can be exchanged and individually adjusted at any time.
Are passive subwoofers better than active ones?
Active subwoofers, on the other hand, offer a number of advantages over passive subwoofers. Active subwoofers are typically more powerful, and they offer greater control over the sound. Additionally, active subwoofers are typically smaller and more compact than their passive counterparts.
So, which type of subwoofer is right for you? Ultimately, the decision comes down to personal preference. If you’re looking for an affordable and easy-to-install subwoofer, a passive model may be the way to go. If you’re looking for more power and control, an active subwoofer may be the better choice.
