PBN Audio MR!777
The MR!777 Loudspeaker
The MR!777 loudspeaker merges two advanced PBN designs in one amazing hybrid. It takes the scale, basic configuration and formidable prowess of the Super League’s Master Reference. The M! Series contributes its uncanny balancing of superb drivers. And the triple seven? Noerbaek isn’t giving away secrets, but “perfection cubed” wouldn’t be a bad guess. Add in custom-matched Bass Towers and EB-SA3 Amplifiers and you have an unrivaled system.
Originating as a custom order, this latest PBN creation exemplifies the tireless impulse to continually push the envelope of acoustic performance ever further – but with the proven engineering of PBN Audio’s quarter-century of audio excellence.

From the first listen the MR!777 delivers astonishing sub-bass authority and chest‑punching dynamics that anchor an enormous, precisely layered soundstage. Dual 12" mids yield transparent, organic midrange realism, while the treble stays energetic yet controlled. Reviewers including Gregory Petan and Audiophilepure praise its build and live‑like immediacy.
Pros
- Massive, authoritative low end — dual 18" woofers provide deep, punchy bass without audible distortion.
- Enormous, precisely layered soundstage and imaging that places instruments with convincing height, width and depth.
- Organic, transparent midrange from twin 12" drivers that preserves timbre and vocal/instrument realism.

Cons
- Very large and heavy — 490 lb cabinets require ample space and careful handling; not suitable for small rooms.
- Extremely high cost restricts value for most buyers; outstanding performance comes at a premium.

Bass
97/100
With two 18" woofers per side reviewers described 'seemingly endless depth' and 'back‑breaking power' without distortion, and kick drums becoming distinct chest punches (Positive Feedback). The speakers deliver authoritative, deep extension and control that match the very large cabinet and driver complement; repeated praise for sub‑bass authority supports a near‑reference rating.
Mid
95/100
Reviewers reported an organic, unforced midrange from the dual 12" drivers, highlighting realistic timbre, transparency, and vocal/instrument presence (Positive Feedback, Audiophilepure). The midband is coherent and detailed through crossover regions, conveying natural textures and live impression.
Treble
93/100
Treble is energetic and extended without being inherently edgy; Positive Feedback noted it 'puts out a good deal of energy' and may feel brighter relative to softer speakers. Detail and air are present while remaining controlled and not harsh when properly matched.
Soundstage Imaging
96/100
Both reviews emphasize an enormous, well‑proportioned soundfield with stable, properly located images in height, width and depth; Positive Feedback highlighted effortless opening of the stage even with wide spacing. Imaging is precise with convincing layering and a strong live sense.
Dynamics
96/100
Dynamics are a standout: reviewers described power, immediacy and realism, with transient impact that retains clarity even at high output ('piercing the cloud cover', kick drums felt). The speakers convey both micro and macro dynamics with apparent headroom and authority.

Build Quality
96/100
Finish and construction were praised as elite: mirror‑polished varnish, book‑matched burled walnut veneer, and visible crossover under acrylic create a high‑end presentation (Positive Feedback). The cabinet and fit/finish are described as workmanship among the best.
Features Connectivity
80/100
Passive tower baseline applied. Reviews list driver complement, frequency response and crossover details but do not cite bi‑wire terminals or DSP features.
Value for Money
70/100
Reviewers acknowledge exceptional performance but also very high cost (retail cited at $83k; product data lists ~$97.8k). While 'top of the mountain' sonics are repeatedly praised, the extreme price constrains value for most buyers.
