Bluesound's PULSE SUB Returns With Dual Opposing 6.5-Inch Woofers and 350 Watts at $1,099 - and No Shipping Date Yet

Bluesound has reintroduced the PULSE SUB, its wireless subwoofer for the BluOS multi-room ecosystem, with a new dual-driver layout and a substantial power bump over the previous generation. The announcement, made 27 August 2026, lays out configuration and connectivity details in full — but leaves several core performance specifications unpublished, a gap worth noting alongside the headline numbers.

Configuration and power

The new PULSE SUB is built around dual opposing 6.5-inch custom woofers, mounted on opposite sides of the enclosure and driven in a force-cancelling arrangement. Bluesound says this opposing layout reduces cabinet vibration and resonance during low-frequency reproduction, a common rationale for facing drivers against each other so their reaction forces cancel out rather than shake the enclosure.

Power comes from a 350-watt amplifier paired with Bluesound's Smart DSP. Bluesound says the new model delivers 2.5 times more power than the previous generation of PULSE SUB — a manufacturer claim rather than an independent measurement, and one the company has not attached a specific prior wattage figure to, so the comparison exists only as a multiplier rather than a stated pair of numbers.

Despite the dual-driver design, Bluesound says the enclosure occupies just over one square foot of floor space. Cosmetically, the company points to soft contours, tonal-weave fabric grilles, matte satin finishes, and built-in cable management channels.

Connectivity and control

The PULSE SUB integrates wirelessly through the BluOS platform, connecting via Wi-Fi or Ethernet like other BluOS components. Bluesound has also included a low line-level analogue input, which lets the subwoofer function as a conventional wired active subwoofer for systems that sit outside the BluOS ecosystem entirely.

Control of the subwoofer — including volume, crossover frequency, and phase — happens through the BluOS app rather than physical controls on the unit itself. Bluesound lists the PULSE SUB as compatible with its PULSE CINEMA and PULSE CINEMA MINI soundbars, the POWERNODE streaming amplifier, and the PULSE M and PULSE FLEX speakers. No compatibility with products outside that list has been stated.

Pricing

Bluesound has published regional pricing for the PULSE SUB as follows:

• $1,099 USD
• $1,299 CAD
• €999 EUR
• £849 GBP

These figures are sourced independently for each region and shouldn't be treated as currency conversions of one another — they're the prices as announced in each market.

Availability

Bluesound says the PULSE SUB will arrive "later in 2026," with preorders opening at an unspecified future date. No firm shipping date, no preorder date, and no region-by-region rollout order have been announced.

What Bluesound hasn't said

The announcement is notably quiet on several specifications buyers typically use to judge a subwoofer's real-world output. Bluesound has not published:

• A frequency response specification
• A maximum SPL figure
• Complete dimensions or a weight
• Whether the 350-watt amplifier rating is continuous or peak power

That last omission matters more than it might seem. Amplifier power figures for subwoofers are routinely quoted as either continuous (RMS) or peak/burst wattage, and the two can differ substantially for the same hardware. Without Bluesound specifying which measurement standard applies to the 350-watt figure — or to the "2.5 times" comparison against the previous generation — the number is difficult to weigh against competing subwoofers or even against Bluesound's own prior model in any concrete way.

Similarly, the absence of a frequency response range or maximum SPL rating means there's currently no published basis for judging how low the PULSE SUB extends or how loud it can play before compression or distortion sets in. Driver cone and surround materials for the "custom" 6.5-inch woofers haven't been detailed either, nor has amplifier class or the specific wireless protocol used for BluOS connectivity beyond the general Wi-Fi/Ethernet framing.

What this means for now

As a launch report, the PULSE SUB news is really two stories layered together: a genuine configuration change — moving to dual opposing woofers in a force-cancelling layout — paired with a headline power claim that Bluesound has been careful to frame as its own figure rather than an independently verified one. The pricing and connectivity details are concrete and consistent across both sourced regions. The performance specifications that would let shoppers compare the PULSE SUB against other subwoofers on paper are, for now, simply not part of the announcement. Whether those numbers appear before preorders open, or only once review units start circulating later in 2026, remains to be seen.

Frequently asked questions

What does the Bluesound PULSE SUB cost and when does it come out?

Bluesound has priced the PULSE SUB at $1,099 USD, $1,299 CAD, €999, and £849. It is set to arrive later in 2026, with preorders opening at an unspecified future date. No firm shipping date or preorder date has been announced.

What driver configuration and power does the Bluesound PULSE SUB use?

The PULSE SUB uses dual opposing 6.5-inch custom woofers in a force-cancelling arrangement paired with a 350-watt amplifier and Smart DSP. Bluesound says this delivers 2.5 times more power than the previous generation, though it hasn't specified whether the 350-watt rating is continuous or peak.

Which Bluesound products is the PULSE SUB compatible with?

Bluesound lists the PULSE SUB as compatible with the PULSE CINEMA and PULSE CINEMA MINI soundbars, the POWERNODE streaming amplifier, and the PULSE M and PULSE FLEX speakers. No compatibility with other products has been stated by Bluesound.

Can the Bluesound PULSE SUB be used outside the BluOS ecosystem?

Yes. In addition to wireless integration over Wi-Fi or Ethernet through BluOS, the PULSE SUB includes a low line-level analogue input, allowing it to function as a conventional wired active subwoofer in systems that don't use the BluOS platform.

What specifications has Bluesound not published for the PULSE SUB?

Bluesound has not published a frequency response specification, a maximum SPL figure, complete dimensions, or a weight for the PULSE SUB. The company also hasn't clarified whether its 350-watt amplifier rating is continuous or peak power.
