Audioengine A5+ vs Klipsch R-51PM
Quick Verdict
Choose the Klipsch R-51PM if you want Bluetooth and the widest range of inputs. Choose the Audioengine A5+ if you have a simple two-source setup and prefer its more compact footprint.
| Spec | Audioengine A5+ | Klipsch R-51PM |
|---|---|---|
| Type | Powered | Powered |
| Power | 50W per channel | Class D amplifier |
| Inputs | RCA + 3.5mm AUX | RCA, optical, USB, Bluetooth |
| Bluetooth | No | Yes |
Key Differences
The R-51PM adds Bluetooth, optical digital, and USB inputs alongside RCA, plus a higher rated power output. The A5+ (wired version) keeps things simpler with RCA and 3.5mm inputs only, at 50 watts per channel.
Connectivity
The R-51PM is the more versatile option for mixed sources, since it can accept a turntable, a TV over optical, a computer over USB, and a phone over Bluetooth, all without swapping cables. The A5+ covers two wired sources at once without an input switch.
Setup
Both are active speaker pairs with the amplifier built in, so neither needs a separate receiver. The R-51PM includes a remote control for source and volume switching from a distance.
