Overview

The Yorkville PSA2S is a professional powered subwoofer built for the rigors of live touring and installed sound — the kind of low-frequency reinforcement tool that system engineers reach for when a venue demands physical presence, not just audible bass. At the heart of the cabinet are dual 15-inch dynamic drivers driven by a 2400W program (4800W peak) Class-D amplifier, a combination that produces the kind of subsonic output that separates professional concert sound from anything the consumer world can replicate. Designed as the dedicated companion sub to Yorkville's PSA1 full-range loudspeakers, the PSA2S is built around the assumption that you're constructing a coherent, scalable system — not mixing and matching disparate components.

Yorkville's decision to build the PSA2S from 15mm birch plywood is not incidental. At sustained high-SPL output, cabinet resonance is a coloration problem — cheaper panel materials flex and introduce their own acoustic signature into the low end. Birch plywood's stiffness-to-weight ratio keeps the enclosure neutral, letting the drivers do the work without the cabinet fighting them. The integrated all-metal pole-mount adaptor adds positioning flexibility for touring applications, and the Class-D topology keeps operating temperatures in check across extended performances. For live sound professionals who demand both punch and precision from their low-end reinforcement, the PSA2S is a purpose-built workhorse designed to hold up through seasons of heavy use.

Frequently Asked Questions

How does the PSA2S integrate with the PSA1 full-range system, and do they share a crossover point?

The PSA2S is specifically engineered as the low-frequency companion to Yorkville's PSA1 full-range loudspeakers. In a stacked or arrayed configuration, the PSA2S handles the sub-bass frequencies that the PSA1's drivers aren't optimized to reproduce, delivering a seamless handoff between the two cabinets. For the cleanest integration, set your crossover point based on the PSA1's low-frequency rolloff characteristics, typically in the 80–100 Hz range.

What does 4800W peak versus 2400W program mean for a live application — how hard can I push this thing?

Program power (2400W) is the continuous working headroom — what the amplifier sustains during a real show with dynamic material. Peak power (4800W) is the instantaneous headroom available for transient spikes like kick drum hits. In practice, you're designing your gain structure around the 2400W program rating. The peak headroom means the amp won't clip or compress those transients, which is where sub performance either sounds tight or smears.

Does the Class-D amplifier in the PSA2S generate significant heat in high-ambient-temperature venues?

Class-D topology runs considerably cooler than Class-AB equivalents at equivalent power, which is a real-world advantage in packed venues or outdoor summer shows where cabinet temps can climb. Yorkville's thermal management in this series is well-regarded among touring engineers for reliability through long performance nights.

Is the PSA2S suitable for permanent installation, or is it primarily a touring cabinet?

The 15mm birch plywood construction and integrated all-metal pole-mount adaptor make it capable in both contexts. For permanent install, the pole mount provides flexible positioning, though deep integration with installed rigging or flush-mount soffits would require custom work. Most installs use it as a freestanding or stacked floor sub.

What connectivity does the PSA2S offer, and can I daisy-chain multiple units?

The PSA2S provides speaker-level input connectivity. For scaled arrays — which Yorkville explicitly supports with the PSA system — multiple units can be configured in stacked or cardioid sub arrangements, which is where this cabinet's scalability becomes a genuine differentiator for larger venues.

Strengths & Trade-offs

👍 Pros

Dual 15-inch drivers move serious air — in a mid-size venue or outdoor stage setup, the PSA2S produces the kind of physical low-end that you feel as much as you hear, without the thinness that single-driver subs can exhibit at high SPL.
The 4800W peak headroom means kick drum transients hit clean and articulate rather than compressing into a low-frequency blur — important distinction in live mixing where low-end definition separates a clear mix from a muddy one.
Birch plywood cabinet construction resists the flex and resonance that cheaper MDF-bodied subs introduce at high output levels, keeping the low-end character controlled and precise.
Class-D amplifier design reduces heat generation and power draw compared to Class-AB alternatives — a practical advantage through a multi-hour festival or corporate event set.
Designed as a scalable companion to the PSA1 system, so engineers building out a full PSA rig have a sub that is acoustically and electrically matched to their tops.

👎 Cons

At this power and cabinet size, the PSA2S is a substantial piece of kit — weight and footprint are real logistics considerations for one- or two-person load-in crews without stage help.
Speaker-level input connectivity is versatile but limits direct integration with some digital snake and networked audio ecosystems that expect line-level or AES3 connections at the sub.
Optimized as a PSA1 system companion — engineers running different full-range loudspeakers will need to tune the integration carefully, as it's not a universal-fit sub in the way some competitors position their products.
Dual 15-inch cabinets at this output level are not compact — positioning in smaller venues requires planning to avoid boundary loading artifacts at the low end.
