The Triangle Tales 340 is a subwoofer with 200 watts of power, designed by the Soissons manufacturer to deliver solid acoustic performance at an affordable price. It is aimed at both music lovers and home theater enthusiasts seeking precise reproduction of low frequencies.
The Tales 340 uses a classic but well-controlled bass-reflex enclosure. Its 250-millimeter downward-firing driver features a long-throw suspension, allowing it to reach deep bass down to 30 Hz. This configuration promotes omnidirectional dispersion of low frequencies, avoiding the acoustic dead zones that are often problematic in small spaces.
The Class D digital amplification delivers 200 watts RMS (350 watts peak), a power level calibrated for rooms up to 30 square meters. This technological choice ensures optimal energy efficiency while limiting heat buildup, allowing the subwoofer to operate for long hours without thermal fatigue.
The cabinet, despite its lightweight construction criticized by some users, incorporates internal bracing designed to limit unwanted resonances. The rear port, positioned near the connectors, allows for relatively close placement to walls—a real advantage in constrained home setups.
Triangle has equipped the Tales 340 with dual connectivity: stereo RCA inputs for traditional hi-fi amplifiers and a dedicated LFE input for home theater amplifiers. This versatility allows the subwoofer to adapt to different setups without the need for additional adapters.
The rear control panel brings together the essential settings. The adjustable crossover frequency knob, ranging from 30 to 120 Hz, allows for seamless integration with the main speakers. The phase inversion switch (0-180°) helps correct acoustic cancellation issues related to placement. The independent volume control makes it easy to balance the overall system.
The automatic standby function, now standard on this type of product, cuts power after a few minutes without signal. This feature, appreciated for its energy savings, can sometimes cause a slight delay when restarting during very soft musical passages.
Measurements reveal a relatively linear response between 32 and 100 Hz, with a gradual roll-off below 30 Hz. This curve meets expectations for a subwoofer in this price range. Distortion remains contained up to about 85 dB SPL, beyond which the amplifier begins to compress the signal.
Some users report a lack of precision in fast transients, particularly noticeable on complex bass lines in jazz or intricate electronic music. The crossover adjustment also lacks finesse, sometimes requiring several tweaks depending on the musical program.
These limitations are explained by the compromises inherent in this price segment. Triangle has prioritized overall musicality over absolute performance—a coherent choice for a product designed to complement modest systems.
Yes, although it is optimized for mixed hi-fi/home theater use. In stereo, it adds body to bookshelf speakers that naturally lack low-end extension. Fine-tuning the crossover and level allows for harmonious integration with most compact speakers.
Triangle recommends rooms up to 30 square meters. Beyond that, the sound pressure may be insufficient to properly fill the space, especially in home theater setups where effects require more impact.
The downward-firing driver allows for some flexibility. Avoid corners, which artificially boost certain frequencies. Placing it midway between the main speakers, slightly offset from the rear wall, is generally a good starting point.
Absolutely. The available settings allow the Tales 340 to be matched with most speakers on the market. Triangle naturally recommends its Plaisir, Borea, and Esprit Ez ranges, but nothing prevents more eclectic combinations.
It works correctly in most cases. Some users report unexpected cutoffs when listening at very low volumes or with very sparse musical passages. Since the activation threshold is not adjustable, this feature can occasionally be frustrating.

It's really great, I'm super happy with it (good bass, simple setup), the visual appearance is top-notch, it goes very well with my Triangle Ares set.
Fast delivery.

Very good value for money in terms of sound quality for a subwoofer supporting HI-FI speakers

Too much resonance
Requires adjustments depending on the type of music
