Norman Labs Model 11 Loudspeaker

Design & Build

• The Model 11 replaced the earlier Model 7, offering a similar configuration—typically a single woofer paired with dual tweeters, or sometimes a more streamlined one-of-each design.

• The cabinets were well-constructed, using quality walnut veneer (and in later units, oak), mounted over sturdy MDF rather than flimsy plywood, lending both elegance and acoustic stability.

Acoustic Philosophy & Sound Characteristics

• Norman Labs' design philosophy focused on balanced, musical performance—especially suited for classical, jazz, and vocal reproductions. Their “East-Coast sound” was reportedly in line with the tonal standards set by AR, Advent, KLH, etc.

• User impressions suggest a laid-back but enjoyable sound, well-adapted to jazz, vocals, acoustic instruments, and orchestral material.

Construction & Components

• Inside, earlier models employed Philips tweeters and Credence woofers, arranged via simple crossover networks—sometimes tweaked by Norman Labs themselves for refined performance.

• Anecdotal accounts recount that some owners upgraded crossovers with quality components like Solen capacitors and silver-coated wiring to breathe new life into aged units, especially Model 11s.

Legacy & Community Sentiment

• In its heyday, the Model 11 was part of a popular lineup across Oklahoma and North Texas. Skilled engineers and founders from Altec and sales-focused background helped Norman Labs gain early traction.

• Owners frequently praise their reliability and sound—some even say they "were some of the best sounding speakers at the time" and still work flawlessly decades later.
