The Focal Sub 600P is an active subwoofer whose sealed design—uncommon in this range—favors precise sound reproduction. It features a Polyflex cone developed in-house by the Saint-Étienne teams. Paired with a 300-watt RMS Class D amplifier, it can reproduce frequencies down to 28 Hz. This model is aimed at both audiophiles and home theater enthusiasts.
Unlike most subwoofers that use a bass-reflex port, the Sub 600P opts for a sealed design. This technical approach, more expensive to implement, offers decisive advantages in terms of precision. The absence of a port eliminates unwanted noise and resonances, allowing for a more faithful reproduction of the original signal.
The sealed design results in tighter, more responsive bass, which is especially appreciated in complex musical passages where every note must be distinct. This characteristic makes the Sub 600P a preferred choice for stereo hi-fi setups, where precision takes precedence over sheer impact.
At the heart of the Sub 600P is a 30 cm driver equipped with a Polyflex cone, a proprietary technology developed by Focal. This composite cone, stiffer and heavier than conventional materials, offers better power handling and reduces distortion. The choice of a 30 cm diameter represents an optimal compromise between bass depth and size, suitable for rooms up to 30 m².
The 300-watt RMS Class D amplifier can deliver up to 600 watts peak. This modern amplification technology combines energy efficiency and low heat output, while preserving the dynamics needed for the most demanding passages. The AutoStandby mode provides intelligent power management, automatically putting the subwoofer into standby when no signal is detected.
The Sub 600P covers a frequency range from 28 Hz to 270 Hz, with a -6 dB cutoff at 26 Hz. This extension into the lowest bass allows it to reproduce the fundamentals of the deepest instruments, from organ to modern synthesizers. The variable crossover frequency between 40 Hz and 200 Hz makes it easy to integrate with different types of speakers.
This versatility is reflected in its dual hi-fi and home theater purpose. In a stereo setup, it adds the missing depth to compact speakers without masking their sonic signature. In home theater, it efficiently handles the LFE channel while complementing the main speakers. Phase settings (0°/180°) allow for optimal time alignment depending on placement.
The Sub 600P’s aesthetics reflect French expertise in finishing. The High Gloss black front panel pairs perfectly with speakers from the Focal Chora and Theva ranges, creating a visually coherent ensemble. The brushed MDF body adds a touch of understated elegance that fits naturally into contemporary interiors.
The removable magnetic grille allows you to adapt the appearance to your preferences. Its compact dimensions (40 x 40 x 42.5 cm) make placement easy, even in tight spaces. The weight of 21 kg, substantial for this size, attests to the solid construction and contributes to stability during the most dynamic passages.
The stereo RCA connections make integration into any audio system simple. The left input also serves as an LFE input for home theater amplifiers. This dual function avoids the need for multiple cables and simplifies installation.
The available settings allow for precise adaptation to each setup. The volume knob adjusts the level according to the associated speakers, while the crossover frequency control optimizes the transition with the main speakers. The phase switch corrects any timing issues related to placement.
Absolutely. Its universal design and fine-tuning options allow for seamless integration with all brands of compact or floorstanding speakers. The crossover and phase settings make it easy to adapt to different sonic signatures.
The sealed design prioritizes precision and the absence of unwanted resonances, while bass-reflex offers more impact and efficiency. The Sub 600P’s sealed approach favors musical fidelity and responsiveness, which are especially valued in hi-fi.
Yes, the technical manual recommends a break-in period to optimize the performance of the Polyflex driver. This phase allows the suspensions to loosen up and the mechanical behavior to stabilize.
Avoid room corners, which artificially boost the bass. Try different positions using the phase adjustment to achieve the best integration with your main speakers. The “one-third of the room” rule is often a good starting point.
This mode improves energy efficiency by automatically putting the subwoofer into standby after a few minutes without a signal. It can be disabled if you prefer continuous operation, especially in professional setups.
Although not officially documented, using two identical subwoofers can improve bass distribution in large rooms. However, be mindful of acoustic interactions, which require careful phase and placement adjustments.

Very effective for a small setup it is tight fast and doesn't drag but may lack power for big home theater scenes

Bought to replace the one in the black Pack Dôme Flax 5.1 system, also from Focal; it changed everything like night and day, clean and powerful bass

Good sub at a fair price. In person it’s a bit big, but next to a sofa I can even use it as a side table!
Thanks
