Audioengine A5 Plus

The Audioengine A5 Plus is a pair of powered speakers that are made of high-quality components featuring custom aramid 5-inch fiber woofers and 0.75-inch silk tweeters. Each speaker is wrapped in a precision-tuned and hand-crafted cabinet. The speakers are available in three colors: bamboo, black, and white.

The left speaker has a power indicator and volume control knob. On its rear panel, you will find a power switch, voltage select, as well as stereo mini-jack input, stereo RCA inputs and outputs. This way, the Audioengine A5 Plus can possibly be the best bookshelf speakers under 500 dollars for music in terms of versatility as they can play music from turntables, all music players, phones, PCs, laptops, notebooks, etc. They also work with TVs with an analog output. Plus, these speakers are supplied with built-in power amplifiers (dual-class AB monolithic). Thanks to them, the A5 Plus provides mighty bass and sound that is very close to originally-recorded music.

The speakers have 150W peak power in total (50W RMS/75W peak per channel), 10 ohms nominal impedance and 88 dB sensitivity level.

In the box, you will find 3.5mm mini-jack audio cable, 4-button aluminum remote control, microfiber speaker bags, and cable bags. The remote has a sleep mode button, mute button, and two buttons to control the volume level.

Each speaker size is 10.75 x 7 x 7.75 inches. However, they have different weight: the left speaker weighs 15.4 pounds and the right one weighs 9.6 pounds.

Klipsch RB-51 II

Klipsch RB-51 II

This model can work as the best bookshelf speakers under 500 dollars for medium-sized rooms thanks to the Klipsch proprietary Tractrix Horn technology. Thus, the RB-51 II units feature a high-efficient horn-loaded design which contributes to accurate and dynamic sound transmission. Plus, thanks to such a design, producing more output while using less energy. They also come with low-diffraction, magnetically-attached grill. However, as for me, the speakers sound much more open with grills off.

An enhanced 1-inch titanium tweeter with linear travel suspension (also used in the Klipsch’s flagship Palladium Series) provides an open and more natural sound. The 5.25-inch high-output cerametallic (hybrid ceramic and metal composition) woofer cones feature treated aluminum which prevents distortion. The woofer does its job well, providing solid bass that dips down to 50Hz. The RB-51 crossover ensures that the midrange driver will give a full frequency response. This model also has a custom internal wiring.

The RB-51 II ones offer 300W peak power (75W RMS), 92 dB sensitivity, and 8 ohms compatible impedance.

The dimensions are 11.4 x 6.5 x 10.75 inches and 20.9 pounds (per pair). In terms of inputs, the speakers offer dual binding posts (bi-wire/bi-amp).

Pros

  • The speakers feature a keyhole bracket for easy wall mounting as well as dual threaded inserts for the stand.
  • The Tractrix Horn technology accurately directs the sound, which, in turn, creates a more lifelike soundstage.
  • They sound especially good with female vocals and classic music.

Cons

  • The sound gets worse when they are placed next to the wall.
  • It takes about an hour for the speakers to warm up.

Q Acoustics 3020i

Q Acoustics 3020i

These monitor speakers go in a 2-way reflex enclosure with rounded edges and are available in four colors: English walnut, arctic white, carbon black, and graphite grey. Featuring a cabinet that is slightly taller and deeper (6.6 x 10.9 x 11.1 inches) than most conventional bookshelf speaker cabinets, these ones deliver wider sound, deeper bass, and increased internal volume which results in an extended low-frequency response. The enlarged front-to-back dimensions also reduce any cone-generated noises reflected from the back wall of the enclosure. However, despite the increased cabinet size, it’s not difficult to locate them in tight places. Moreover, each speaker weighs 10.59 pounds.

The design allows them to be shelf- or stand-mounted. Plus, instead of conventional terminal panel cutouts, the 3020i is equipped with low-profile binding posts. The sockets are deep enough to accept 0.16-inch banana plugs so the speakers can be placed very close to a rear wall.

The 3020i are supplied with a 5-inch high-frequency driver with a large surround which creates wider sound dispersion. The 0.9-inch tweeter is decoupled from the baffles which allows it to isolate any vibrations from the woofer, reproducing audio content with less interference. The speakers have 6 ohms impedance, 88 dB sensitivity, and 50-125W power output.

In addition, the kit includes two speaker grilles, two foam bungs, and a pair of handling gloves.

Pros

  • The point-to-point bracing reduces sound distortion so the soundstage is accurate.
  • The coated paper cone ensures an optimum balance between stiffness and self-damping, minimizing unwanted resonances.
  • The speakers have a great ability to reproduce dense orchestral textures thanks to the deeper-than-average cabinet.

Cons

  • The speakers are not good when it comes to bass-heavy genres.
  • Quite an average volume level, so they are not very loud.

The 5.25-inch woven woofer with aramid-fiber has pretty stiff surround. The revised shape of the aramid cone allows for improved damping which is better than the one in polypropylene or paper cones. The woofer’s dust cap is flexible and thin and helps the woofer properly disperse higher frequency sound.

In terms of technical specs, the manufacturer managed to optimize the speakers to minimize the power requirement from the receiver. This way, they have 6 ohms impedance, 86 dB sensitivity, and 120W power.

Buyer’s Guide

What Quality Can I Get From Bookshelf Speakers Under $500?

Bookshelf speakers under $500 belong to a quite competitive segment. Many manufacturers tend to imply some of the high-end technologies from their flagship series into more low-cost models with an intention to attract more buyers. This way, the best bookshelf speakers for under 500 dollars can be extremely close to some very pricey models.

Technologies make the manufacturing of the speaker’s cabinet much easier. This way, even the budget speaker’s enclosure is frequently made of solid MDF or thick plastic being both cheap and durable.

In some cases, the bookshelf speakers under $500 can even please the needs of audiophiles as some of such speakers can have some exclusive and even exotic features. Plus, almost all of them have decent crossovers. Note that the wattage is essential for any bookshelf speakers so make sure to connect them to an amplifier that provides wattage in a decent range.

Going for more costly speakers, you may get better quality of work with no issues and a more powerful sound. However, usually, the high-cost models are designed for big rooms.

Audio Performance

The frequency of the speakers determines the range that can be reproduced. Our ears perceive 20 – 20,000 frequencies (Hz).

The impedance constantly fluctuates while the music is playing. Low-impedance speakers don’t interact with receivers and amplifiers in a proper way if they don’t bring a big amount of current.

The sensitivity level (measured in decibels) shows how the speaker converts the amp’s power into acoustic energy. This way, the loudness of the speakers depends on how big the sensitivity rating is. However, the sensitivity rating can create some differences. For instance, a speaker with a 3 dB sensitivity rating will require half more power to provide the same amount of sound. The speakers with minimal sensitivity won’t fill even a small room with sound while the speakers with high sensitivity level provide enough volume for the identical power which is perfect for large-sized spaces.

Power & Impedance

Power and impedance are the most important and the most common values you should look for when choosing any type of speaker. The power measures in watts, while the impedance measures in ohms.

If the speakers have a power rating that is less than 150W, you have to connect them to the amp within the range. If you connect them to the amp that provides more watts, it doesn’t always mean that it will blow your speakers. However, if you are used to playing music very loud, you can start having a problem with drivers. Although the speakers that provide less than 50W of power may be too quiet.

The impedance is responsible for how much current the speaker needs. The lower the impedance the more current will be flowing through. The amp has to deliver the current to a speaker rated at a specific impedance.

Most speakers are rated with 8 ohms impedance so you probably won’t have to worry about it. However, if you are going for speakers with 4 ohms impedance, ensure that your amp/receiver will be able to handle it.
