Overview

The Premium 301 Gen2 combines PIEGA’s new RM 01-24 magnetostatic ribbon tweeter with a 140 mm FSD-M mid-woofer in a compact aluminum-extrusion cabinet. The design targets lower cabinet resonance and improved treble linearity/distortion through a revised magnet topology for the ribbon[1][2].

Scientific Validity

\[\Large \text{0.5}\]

Manufacturer specs list 39 Hz–50 kHz (±2 dB) frequency range, 4 Ω nominal impedance, and ~88–89 dB sensitivity (documents differ slightly)[1][2]. As comprehensive third-party measurements for the Gen2 are not yet widely published, conclusions remain provisional. Speakers carry a 6-year warranty[3].

Technology Level

\[\Large \text{0.7}\]

The symmetric magnet arrangement of the RM 01-24 ribbon is a rational approach to improving linearity and transient behavior; the rigid aluminum extrusion reduces enclosure resonances. These are competent, incremental advances rather than category-defining breakthroughs[1][2].

Cost-Performance

\[\Large \text{0.6}\]

Comparator (cheapest we can confidently judge equal-or-better): KEF LS50 Meta — passive two-way standmount with excellent independent measurements; manufacturer FR ±3 dB 79 Hz–28 kHz and very low THD at 90 dB[4][5].
Price basis:

• Review target: official MSRP 2,500 EUR/pair (silver finish) → 2,725 USD using the review-date official rate; used as the denominator for CP[2].
• Comparator: 1,599.99 USD/pair (US official site)[4].

Calculation: 1,599.99 USD ÷ 2,725 USD = 0.587 → 0.6 (rounded to one decimal).
Equivalence note: both are passive two-way bookshelves; the LS50 Meta’s public spin-style data shows smoother on/off-axis response and low distortion that meet or exceed transparency targets, so it qualifies as equal-or-better while Gen2 data remain limited[4][5].

Reliability & Support

\[\Large \text{0.8}\]

A clearly stated 6-year speaker warranty (with authorized-dealer purchase and timely registration) and robust aluminum cabinetry support long-term durability[3].

Rationality of Design Philosophy

\[\Large \text{0.7}\]

Prioritizing enclosure rigidity and driver linearity (ribbon magnet topology) is scientifically sound for fidelity. The direction is rational, but without independent data at launch, demonstrable advantages over cheaper, well-measured competitors remain unproven.

Advice

If you prize compact aluminum construction and ribbon-tweeter traits from a Swiss build, the Premium 301 Gen2 is appealing. If performance-per-dollar is paramount, KEF LS50 Meta offers proven measurements at a far lower price.
