Audioengine A5+ Wireless Review: Hi-Fi Without the Amp Line-Item

Every passive-speaker budget hides a line-item that first-time buyers forget: the amplifier. Speakers get researched for weeks; then the checkout math quietly grows an amp, speaker wire, banana plugs, and a shelf to put it all on. The Audioengine A5+ Wireless is the argument for skipping that entire aisle — a powered pair where the amplification is designed in, matched to the drivers, and already paid for. List price is $499 a pair, and the honest question is not "are these good speakers" but "is this whole chain the right chain for your room."

That question has a numerate answer, so let's grade it properly: published specs labeled as manufacturer claims, whole-chain cost math, and a verdict that names the rooms where the A5+ actually belongs.

The numbers that matter

Spec	Audioengine A5+ Wireless (mfr spec)
Woofers	5-inch aramid-fiber
Tweeters	3/4-inch silk dome
Amplification	Dual class A/B amps in the left speaker
Power	150W peak total (50W RMS per channel)
Frequency response	50 Hz–22 kHz ±1.5 dB
Wireless	Bluetooth with aptX HD, AAC, SBC
Inputs / outputs	RCA and 3.5mm in; variable RCA line out; USB charge port
Extras	Remote control included
List price	About $499 per pair

The row to respect is the response window: 50 Hz–22 kHz ±1.5 dB. That is a tighter tolerance than most passive speakers publish at any price, and the honest 50 Hz floor is exactly what a 5-inch woofer in a compact cabinet should claim. When a similarly sized speaker advertises 35 Hz with no ±dB window attached, one of you is being optimistic. Our frequency response glossary entry explains why the window is the spec; Audioengine naming a tight one is a small credibility signal that the rest of the sheet was written by engineers rather than marketing.

These are manufacturer numbers — we grade published specs and say so plainly. What the sheet does not capture: class A/B amplification (not the class D usual at this price) means the amps run warm and the cabinets are heavier than they look, about which nobody has ever complained twice.

The missing-amp math

Here is the chain cost the A5+ deletes, priced against a sensible passive build at street prices:

Line item	Passive route	A5+ Wireless route
Speakers	$300–400 (good passive pair)	$499, amplification included
Amplifier	$90–350	—
Speaker wire + plugs	$20–40	— (link cable included)
Bluetooth input	Depends on amp	Built in, aptX HD
Total boxes on the shelf	3+	2 speakers

Run the totals and the passive route spans roughly $410-790 for comparable capability, with more cables, more decisions, and one more thing to place. The powered route is one decision. That is the real product: not magic sound per dollar, but a matched, finished system with no forgotten line-items.

The skeptic's caveat, stated plainly: powered means the amp and speakers upgrade as one unit. A passive chain built around a streaming amplifier upgrades piecewise — better speakers this year, better amp in three. If you enjoy that ladder, read our WiiM Amp review for the other road. If you want to buy once and listen, keep reading.

Placement still decides the outcome

No DSP, no room correction, no boundary switches — the A5+ is an analog design that trusts you to place it. So place it: tweeters at seated ear height, a hand-span or more of breathing room from the wall behind, and a slight toe-in toward the listening seat. On a desk, angle them up or put them on risers; a tweeter firing at your sternum is a treble control you did not mean to install.

In a room, dedicated speaker stands are the unglamorous upgrade that beats any cable: correct height, less shelf boom, cleaner midbass. Twenty minutes of placement work here is worth more than the next $200 of gear, which is the recurring theme of every review we write.

Where the bass ends, and what to do about it

An honest 50 Hz reaches the fundamentals of nearly all pop, rock, and acoustic music. What it does not reach: the bottom octave of electronic music, film scores, and pipe-organ party tricks. The A5+ answers with a variable RCA line out — connect a subwoofer, set the sub's own low-pass around 60-80 Hz, and the pair becomes a legitimate 2.1 system. Note the output is full-range and the speakers keep playing full-range too; there is no bass-management high-pass here, which is fine at these woofer sizes and levels.

Our pick for that job in a small room is the sealed sub we graded in the SVS SB-1000 Pro review — current pricing here. Small room, sealed cabinet, done; the reasoning is in that review and in our room matcher.

What it is not

• Not a network streamer. Wireless means Bluetooth — aptX HD and AAC, which is plenty at couch distance — but there is no Wi-Fi, AirPlay, or casting. A small streamer into the RCA input adds that later without replacing the speakers.
• Not a home-theater front end. No HDMI, no optical input. TV duty over Bluetooth or 3.5mm works but this is a music system first.
• Not a large-room system. Fifty clean watts per side into 5-inch woofers is honest small-room power. Past roughly 1,500-2,000 cubic feet at spirited levels, you are asking the cabinet for cone area it does not have — that room wants passive towers or serious standmounts with a dedicated amp, which is a different budget and a different review; see bookshelf vs tower speakers for the dividing line, and let the room matcher place you on it.

Also worth naming: at moderate desk levels these will happily play all day, and desk listening creeps louder over hours. Around 85 dB is where sustained exposure starts costing you by every published occupational guideline; nearfield speakers make it easy to live below that without feeling deprived. Use the proximity.

Verdict, by room

• Desks and nearfield setups: A. This is the natural habitat — the aramid woofers and silk domes at one meter, no hiss to speak of, remote in the drawer. Better-resolved than nearly anything sold as "computer speakers."
• Small rooms, under 1,500 cubic feet: A−. Real listening levels with composure; add the sub for the last octave and it embarrasses plenty of separates chains at the price.
• Medium rooms: B−. Moderate levels only, and the subwoofer stops being optional.
• Large rooms: not the tool. No grade adjustment will change the cone area.

Within the powered lane, this is the benchmark our best bookshelf speakers roundup measures other powered pairs against; the full ranked list is on the best-of index. If your use is 90% listening with a little recording on the side, also read studio monitors vs hi-fi speakers before deciding which wing you are actually buying for.
