MartinLogan Foundation B2: Exceptional Sound Performance

Bookshelf speakers have long been a popular choice for those seeking high-quality sound without sacrificing space. These speakers offer the perfect combination of audio performance and compact size, making them a versatile option for various environments. Whether you’re looking to enhance your home listening experience or desire a shelf-mounted solution, the MartinLogan Foundation B2 speaker might just be the answer to your needs.

Tweeter: Gen2 Obsidian Folded Motion Tweeter S

One of the exceptional features of the MartinLogan Foundation B2 is its Gen2 Obsidian S Folded Motion Tweeter. This revolutionary tweeter delivers unparalleled performance through innovative technology. By folding a thin film, MartinLogan has managed to incorporate a larger surface area into a reduced space. The result? An incredibly fast and responsive tweeter capable of reproducing even the most delicate sonic nuances with stunning clarity and detail. Thanks to this cutting-edge technology, the Gen2 FMT S provides a truly exceptional listening experience.

Controlled Dispersion: Folded Motion Waveguide

To further enhance the sound quality and precision of the Foundation B2 speaker, MartinLogan has incorporated the Folded Motion Waveguide. This unique technology optimizes the tweeter’s dispersion, ensuring optimal coverage of the listening area with incredible detail. Moreover, the Folded Motion® Waveguide reduces room reflections that could compromise sound performance while providing a more consistent sonic experience, no matter where you are seated in the room.

The Art of Sound Reproduction: Aluminum Mid-Bass Driver

One of the cornerstones of the Foundation B2’s audio performance is its aluminum mid-bass driver. MartinLogan has leveraged the unique properties of aluminum to maximize clarity, detail, and bass and midrange output. Utilizing proven trickle-down technology from the Motion XT and Motion series, the B2 speaker delivers exceptional sound reproduction that upholds MartinLogan’s legendary reputation.

The Legendary Sound of MartinLogan

MartinLogan speakers have earned their place as a benchmark in the world of high-quality sound reproduction. Known for their ability to articulate every musical detail with realism, MartinLogan speakers provide an unparalleled listening experience. With technological advancements such as the Gen2 Obsidian Folded Motion Tweeter S and the Folded Motion® Waveguide, MartinLogan speakers elevate sound to a higher level, offering total immersion in music, movies, and any other audio content.

I took the time to break in these new speakers (or perhaps I should say my ears!), and after 2 months I think I have a pretty clear idea. I don't want to be too enthusiastic, but these Martin Logan B2 are something of a revelation; they replace a pair of Q Acoustics Concept 20 which gave me a lot of satisfaction — speakers with a very good press, all things considered — but listening mostly to rock, blues, and jazz, I was left wanting more, it was all a bit tame, very musical and fairly dynamic nonetheless... but these B2 have taken me to the next level, that of live music. At first I was a little surprised, finding them a bit "forward", but as the break-in progressed, that high-frequency presence transformed into genuine presence and the listening experience gained in coherence. These speakers go low with punchy bass (I kept my Highland 265 subwoofer to add body to the low end, the low-pass filter set low — my living room is 60 m²!), and the mid/treble is now a real pleasure. This ribbon tweeter is a knockout — cymbals finally present with intensity rather than buried in the mix, the drums come alive, vocals and guitars are superb, and the dynamics are no slouch either. I'm glad I broke the piggy bank for these B2 bought as second-hand... I can only recommend them to anyone looking for lively speakers with a magnificent sound. On the other hand, they show no mercy to poorly recorded or mixed tracks, and there's no enjoyment to be had there!!
My combo Cambridge CX A81 / Martin Logan B2 / Eversolo DMP A6 Master Edition, Mogami cables plus the Q Acoustics speaker stands I kept, is everything I could ask for. I will however try using the Eversolo acoustic correction microphone, as I lose coherence when I push the volume fairly high.
I also used G.. LE's AI to advise me on settings for the Eversolo's parametric equalizer — it's relevant and interesting, definitely worth trying out!

J'ai pris le temps de roder ces nouvelles enceintes (ou peut être devrais je parler de mes oreilles !), et passés 2 mois je pense avoir une idée assez nette. Je ne veux pas être trop enthousiaste, mais ces Martin Logan B2 sont quelque part une révélation; elles remplacent une paire de Q Acoustics concept 20 qui m'ont apporté beaucoup de satisfaction, enceintes avec très bonne presse au demeurant, mais écoutant du rock, blues, jazz majoritairement, je restais sur ma faim, tout cela était un peu sage, très musical et assez dynamique cependant... mais ces B2 m'ont fait franchir un cap, celui de la musique vivante, au début j'étais un peu surpris, les trouvant un peu "montantes", mais le rodage se faisant, cette présence des hautes fréquences s'est muée en réelle présence et l'écoute à gagnée en cohérence, ces enceintes descendent bas avec des basses qui claquent (j'ai gardé mon caisson highland 265 pour donner du corps aux basses, le filtre passe bas réglé bas, mon séjour fait 60 m2!), et le medium/aigu est maintenant un vrai plaisir, ce Tweeter à ruban fait un malheur, enfin des cymbales présentes avec intensité et non plus noyées, la batterie vit, les voix et les guitares sont superbes, et la dynamique n'est pas en reste, je suis heureux d'avoir cassé ma tirelire pour ces B2 proposées en 2ème vie... je ne peux que les conseiller à quiconque cherche des enceintes vivantes et au son magnifique, par contre elles ne font pas cadeau aux enregistrements et mixage approximatifs et là il n'y a plus de plaisir !!
Mon combo Cambridge cx a81/ Martin Logan B2/ Eversolo Dmp A6 master edition, cables Mogami plus les super pieds Q Acoustics que j'ai gardés me comble. J'essaierai cependant d'utiliser le micro de correction acoustique Eversolo car je perds en cohérence quand je pousse le volume assez haut.
J'ai aussi utilisé l'IA de G.. LE pour me conseiller des réglages pour l'egaliseur paramétrique de l'Eversolo, c'est pertinent et intéressant, à tester réellement !

Definitely a very "transparent" pair of speakers, with such a clarity and detail in the high end layer. The bass is quite good taking in consideration the size, being well articulated and punchy. Love the absence of coloration and can listen for hours without feeling fatigue. Really surprised by the quality as is an entry level speaker. I have it paired with a Marantz M1, so the overall result is an amazing clarity for the midrange and highs with fast transients. They're an excellent pair of speakers!
