Te koop: een krachtige infinity sm 155 vloerstaande luidspreker. Deze speaker levert een indrukwekkend geluid en is ideaal voor de echte audioliefhebber. De speaker is gebruikt, maar verkeert in goede
At €300, this Infinity SM 155 listing sits right at the median of the recent EUR market, where the 25th percentile is €251 and the 75th is €323, making the asking price fair rather than a bargain or an overreach. It’s not a steal, but it’s squarely in line with what enthusiasts are currently paying for used SM-series speakers in comparable condition.
The SM 155s are well-regarded for their smooth midrange and tight bass, a hallmark of Infinity’s classic domestic studio monitors that still deliver credible hi-fi performance today. If these are in original-owner shape with intact grilles and no visible damage, €300 is a solid entry point into a respected, often overlooked line that rewards careful listening. Watch for worn foam surrounds or cracked plastic, but at this price, minor wear is acceptable if the sound remains clean.

Infinity emerged in 1968 from a Woodland Hills, California garage, founded by Arnie Nudell, John Ulrick, and Cary Christie. Driven by Nudell's passion for classical music and innovative engineering, the trio launched with the groundbreaking Servo-Statik speaker system, featuring electrostatic panels paired with a servo-controlled woofer derived from defense technology. This American brand quickly gained traction through pioneering materials like neodymium magnets, mylar diaphragms, and polypropylene cones, establishing a legacy of pushing audio boundaries before acquisitions by Electro Audio Dynamics in 1974 and Harman International in 1983.
The company has long focused on loudspeakers as its hallmark, from early electrostatic hybrids and the iconic Reference and Kappa series to later EMIT and EMIM drivers in the 1970s. While primarily a speaker specialist, Infinity has ventured into home and mobile audio, including amplifiers and systems under Harman ownership, now part of Samsung since 2017. Turntables, DACs, headphones, and cables remain outside its core expertise.
Positioned as a mid-tier powerhouse with high-end aspirations, Infinity commands respect among knowledgeable buyers for its vintage collector appeal and enduring innovations. Once a darling of audiophiles for transparency and dynamics, it now blends accessible performance with Harman reliability, appealing to those seeking proven heritage without boutique exclusivity.
