At AXPONA 2025, Vandersteen Audio pulled back the curtain on two highly anticipated additions to its lineup: the production version of the L5-ACC Audio Control Center and the newly refined Quatro Wood CT Evo which will be shipping this fall.
Vandersteen L5-ACC Audio Control Center
The L5-ACC Audio Control Center ($15,000 U.S.), shown in its final production form, is Vandersteenโs take on the ultimate linestage. A minimalist in the best sense, the L5-ACC features a signal path distilled down to just five carefully selected components, each chosen for absolute transparency and phase integrity. The result is a level of resolution, dynamic nuance, and holographic realism that demands attentionโeven in a hotel room system. As attendees quickly discovered, this isnโt a preamp that adds anything to the musicโit simply steps out of the way.
While its circuit topology is ruthlessly clean, the L5-ACC doesnโt sacrifice usability. The remote control is thoughtfully laid out, the chassis is both resonance-controlled and mechanically grounded, and input flexibility has been built in without polluting the signal path. The power inlet is center-mounted on the rear panel, directly feeding the primary circuitโone of many deliberate choices aimed at keeping noise at bay.
Smoke and Mirrors module
A surprise talking point at the show was Vandersteenโs optional โSmoke and Mirrorsโ moduleโa fully bypassable suite of tools designed for the real-world listener. While purists will be relieved to know these features are never in the signal path when the โDirectโ mode is engaged, the module adds thoughtful control options: tone adjustments, mono/stereo blending, and a matrix mode inspired by classic vinyl-era circuitry. Priced at $250, the module can be omitted at time of order, and either way, the circuit remains identical in direct mode. Those who heard it in action at the show walked away impressedโnot because it changed the Vandersteen sound, but because it let them recover musical joy from flawed recordings without compromise.
Vandersteen Quatro Wood CT EVO
Also unveiled at AXPONA was the Quatro Wood CT Evo ($23,900 U.S. a pair), a speaker that exemplifies Vandersteenโs ability to blend cutting-edge innovation with pragmatic design. It borrows heavily from the flagship lineup, including the carbon-fiber tweeter from the 5A Carbon and the patented Reflection-Freeโข midrange driver, which helps maintain tonal clarity and reduce room-induced smear. These drivers are time- and phase-aligned in true Vandersteen tradition, which could be clearly heard in the way images hung effortlessly in space during listening sessions.
The CT Evo integrates powered dual 8-inch CounterForce subwoofers, driven by internal amplifiers and shaped via an onboard 11-band EQโallowing it to adapt to virtually any room without the need for external DSP or crossovers. Setup is straightforward, with bi-wire connections to any suitably robust amplifier. Visually and physically refined, the Evoโs real wood finishes and compact footprint make it unusually approachable for a speaker that can dig this deepโand with such composure.
Vandersteenโs room at AXPONA wasnโt about flash. It was about delivering a coherent musical experience, driven by engineering that serves the music above all else. Both the L5-ACC and Quatro CT Evo embody this philosophyโrelentlessly focused on the integrity of the signal and the emotional impact of the performance. For audiophiles chasing the elusive intersection of realism and engagement, Vandersteen quietly made a strong case: this is where you listen differently.
