Short answer: the Adam Audio T5V. It ranks #12 of 64 powered bookshelf speakers by sound quality at $239.99; the Sigberg Audio SBS Gen 2 ranks #24 and costs $18043.20, so there is not much of a tradeoff to weigh.
What the Adam Audio T5V offers: Better than the HS5 in terms of vocals detail and better low end. Watch for: Elevated, slightly uneven top end from the AMT tweeter, shared with Adam’s other T-series monitors - the rear treble trim only tilts the response rather than flattening it. Distortion, while better controlled than most speakers in this price range, isn’t reference quality.
What the Sigberg Audio SBS Gen 2 offers: The best-measuring of Sigberg’s three active systems, with a 6.74 Spinorama preference score with a perfect subwoofer versus 6.26 for the SBS.1 and 5.91 for the Manta. This is the appropriate apples-to-apples comparison because all three are designed for use with companion subwoofers. Unlike the other two measurements, the SBS Gen 2 data includes its subwoofer and verifies 24Hz bass extension. Its updated asymmetric 1st/3rd-order linear-phase crossover also delivers the best on-axis linearity and in-room and sound-power smoothness of the three. Active 3-channel Hypex nCore Class D amplification (350W per speaker) includes a 9-band parametric EQ. Watch for: Slightly wider directivity variation than the Manta (spinorama directivity index standard deviation 3.27 versus 2.50), though broadly comparable to the SBS.1’s 3.19. Sold only as a complete speaker-and-subwoofer system with pricing well into flagship territory. Built to order with a lead time of several months.
Buy the Adam Audio T5V. It ranks higher for sound quality than the Sigberg Audio SBS Gen 2 and costs less, so there is no real case for the other one.
