The Triangle Elara LN05A is designed for listeners who want the scale and visual presence of floorstanding speakers without building a system around a separate amplifier. It is an active 2.5-way stereo design in which the powered main speaker drives its passive partner, reducing the number of components required while preserving conventional left-and-right stereo placement. Its appeal extends beyond simple space saving: analog, digital, wireless, phono, and subwoofer connections make the LN05A adaptable to a wide range of sources. Compact cabinets, reinforced construction, two 135 mm bass/midrange drivers per speaker, and a 25 mm silk-dome tweeter complete a design intended for rooms of practical domestic proportions.
A floorstanding system with amplification built in
The defining feature of the Elara LN05A is its active architecture. Rather than requiring an external integrated amplifier or receiver, the system places its electronics and source connections in the main speaker. Conventional speaker terminals then carry the amplified signal from that main cabinet to the passive partner. This arrangement retains the channel separation and physical layout of a traditional stereo pair while simplifying the equipment between the source and the speakers.
Triangle specifies a rated music power of 90 W. More important from a system-planning perspective is that the amplification and speakers are supplied as a coordinated package. Owners do not need to select a separate amplifier, allocate shelf space for it, or work through basic power-matching questions before the system can be used.
At 900 mm high, 165 mm wide, and 263 mm deep, the LN05A has a relatively narrow footprint for a floorstanding model. The specified weight is 13 kg. Its proportions allow it to provide the standing height and driver capacity associated with a tower speaker without requiring an especially broad cabinet. Triangle recommends the system for rooms measuring between 15 and 30 square metres, assuming ceiling heights of up to three metres.
Drivers selected for broad frequency coverage
Each cabinet uses two 135 mm cone drivers to cover bass and midrange duties. Their diaphragms are made from specially impregnated paper, and the drivers incorporate an advanced magnetic system. Using two units gives the slender enclosure more radiating area than a single-driver arrangement while supporting the LN05A’s 2.5-way configuration.
High frequencies are assigned to a 25 mm silk-dome tweeter. Silk is a familiar diaphragm material in domestic loudspeakers because it permits a lightweight dome construction, while Triangle specifies extension to 22 kHz. The complete system is rated from 47 Hz to 22 kHz within a ±3 dB frequency-response tolerance.
Those figures indicate that the LN05A is intended to operate as a self-contained full-range music system for everyday rooms. At the same time, Triangle includes a dedicated mono RCA subwoofer output. That gives owners a clear expansion path if they want additional low-frequency support, whether for music, television, or other connected sources, without replacing the main speakers.
Connections for analog, digital, and wireless sources
The rear connection panel is central to the LN05A’s usefulness. Its analog options include RCA and 3.5 mm mini-jack inputs. The RCA connection can be switched to phono mode, allowing a compatible turntable to be connected without adding a separate external phono preamplifier. For someone assembling a compact vinyl system, that can remove another box and an additional set of interconnects.
Digital equipment can be accommodated through optical Toslink and coaxial inputs. The optical connection is particularly relevant to televisions and many media players, while coaxial digital provides an alternative for compatible disc players, streamers, and other digital sources. Because conversion and amplification take place within the active speaker system, source components can remain comparatively simple.
Bluetooth 4.0 with A2DP and aptX support provides the wireless option. It allows phones, tablets, and computers to send audio directly to the speakers, making the system convenient for casual playback or for households in which several people share the same audio setup. Bluetooth does not replace the wired inputs; instead, it complements them by giving the LN05A a quick connection method alongside its more permanent analog and digital sources.
Taken together, these inputs make the speakers suitable for mixed-source systems. A turntable could occupy the phono-capable RCA input, a television the optical input, a portable device the 3.5 mm connection, and mobile products Bluetooth. The subwoofer output remains available if the system is expanded later.
Cabinet engineering for a compact tower
The LN05A enclosure is constructed from pressed MDF, with 18 mm side walls and a thicker 21 mm front baffle. Internal stiffening ribs are used to control cabinet vibration and resonance. These are meaningful construction details in a narrow floorstander, where the enclosure has to support multiple drivers while remaining sufficiently rigid over its 900 mm height.
A front-facing bass-reflex port uses a long duct and a rounded opening intended to reduce turbulence. Front porting can also make room placement more manageable than it might be with a port firing directly toward the wall behind the speaker. It does not eliminate the need to experiment with positioning, but it is a practical decision for the smaller rooms in which Triangle expects the LN05A to be used.
The cabinets receive several layers of piano lacquer, giving the speakers a polished furniture-grade appearance. Magnetically attached fabric grilles keep the front baffles free from visible mounting points when the grilles are removed. Black or white grilles correspond to the main speaker color, allowing the system to fit into light or dark interiors without changing its basic design language.
Why the format may be easier to live with
Active stereo speakers occupy a useful middle ground between conventional separates and a single wireless speaker. The LN05A requires a cable between the main and passive cabinets, as well as power for the active side, but it avoids the extra footprint of a separate amplifier. It also maintains two physically separated channels, which lets owners position the speakers according to the room and seating arrangement rather than accepting the fixed spacing of an all-in-one enclosure.
The floorstanding format removes the need to purchase dedicated stands, although careful placement remains important. The narrow cabinet should also be easier to accommodate beside a media console or on either side of a low equipment unit than a wider tower. Meanwhile, the range of inputs reduces dependence on any one playback format or source ecosystem.
Its connectivity also supports gradual system development. An owner can begin with Bluetooth or a direct television connection, add a turntable through the switchable phono input, and later integrate a powered subwoofer. That modularity is valuable for people who want a straightforward initial setup without closing off common upgrade options.
Who the Triangle Elara LN05A is best suited to
The LN05A is most suitable for listeners furnishing a small or medium-size room who want a genuine stereo pair but prefer not to assemble a traditional amplifier-and-speaker system. Its recommended room range of 15 to 30 square metres provides a useful guideline, while its 900 mm height and slim 165 mm width make it particularly relevant where floor area is limited.
It also makes sense for owners with several different source types. The combination of phono-capable RCA, mini-jack, optical, coaxial digital, Bluetooth aptX, and a subwoofer output is broader than a system designed solely around wireless streaming. Turntable users, television viewers, and people playing music from mobile devices can therefore share the same speakers without continually changing cables.
There are, however, situations in which another format may be more appropriate. Listeners who already own an amplifier they want to keep may prefer passive speakers, while those seeking network streaming services built directly into the speaker should note that the documented wireless feature is Bluetooth rather than an integrated Wi-Fi streaming platform. Very large rooms also fall outside Triangle’s stated 15-to-30-square-metre recommendation. The LN05A’s strengths are most relevant when convenience, source flexibility, stereo separation, and a compact floorstanding form are higher priorities than building a fully modular separates system.
Conclusion
The Triangle Elara LN05A brings together the practical advantages of active speakers and the room-filling format of a slim floorstander. Its two 135 mm bass/midrange drivers, 25 mm silk-dome tweeter, reinforced MDF enclosure, and front-facing reflex port form a clearly specified acoustic platform, while built-in amplification eliminates the need for a separate amplifier. Phono-capable analog input, optical and coaxial digital connections, Bluetooth 4.0 with aptX, and a mono subwoofer output give the system unusual flexibility for a compact stereo installation. It is best suited to listeners with small or medium-size rooms who want to connect a mixture of turntables, televisions, digital components, and mobile devices while keeping the overall system straightforward and visually coherent.
