Bang & Olufsen Beolab 4500 (?)
An active speaker from Bang & Olufsen, the Beolab 4500 remains a shadow in the brand’s storied lineup—documented in listings but absent from period literature.
Overview
The Bang & Olufsen Beolab 4500 is confirmed to exist as an active speaker system, with current listings identifying it by the exact name "Beolab 4500" and specifying its powered nature. While no production years, technical documentation, or original marketing materials have surfaced in the available research, its classification as an active speaker aligns with B&O’s broader push into self-amplified designs. The only confirmed specification is a long-term maximum output power of 116 watts per module, as listed by Kose Trading—a figure that suggests robust internal amplification, though the nature of the amplifier circuitry, driver complement, or frequency response remains undocumented. No period reviews, technical manuals, or contemporary advertisements in the provided sources mention the model, leaving its design philosophy and sonic character unverified by independent testing or critical assessment. HiFI-Stereo (February 1995, p.110) mentions the Beolab Penta as a bass-reflex design with four 5-inch woofers, four 3-inch midranges, and a 1-inch dome tweeter; amplifier power is not specified in this source.
Collectibility & Value
Current resale listings indicate the Beolab 4500 commands a price of €550.00, as noted by Vendora.cy, which also highlights the inclusion of original wall brackets—a feature described as rare. TMR Audio’s listing for the same model confirms that wall mounting hardware is often included, suggesting these accessories have survived in the secondary market. Each unit is offered with two power cables, according to Vendora.cy, indicating that complete setups are occasionally available. However, no data exists on original pricing, production volume, or common failure modes, making it difficult to assess whether the current market valuation reflects rarity, demand, or simply the premium associated with the Bang & Olufsen name.
