This is an excerpt from another manufacturers site (Paradigm):
"To ensure superior sonic uniformity, we match every speaker to within 1/2 dB of its production reference!
How? By insuring a higher level of precision at every stage of production. Here are just a few examples:
We wind voice coils to ±0 turns so impedance cannot vary and cause response inconsistencies. ±1 turn is the typical industry standard. The magnetic gaps in our magnet structures have tolerances of ±0.025 mm (±0.001 in) to ensure higher unit-to-unit consistency. Cone material is batch-purchased to eliminate run-to-run variations.
Capacitors are hand-selected for ±5% tolerance. The industry standard is typically ±20%. We hand-select resistors for ±2% tolerance. The industry standard is typically ±10%. Our inductors are wound to ±1/2 turn. The industry standard is typically ±3 turns."
I am curious as to how Axiom measures up. What does Axiom do to ensure a quality speaker? While I believe that the ear is always the ultimate test...I still like to know what kind of quality control goes into the design.

Northcreek Music also hand matches the speakers themselves to +- 1.5 db before break in or +- .5 db after break-in. Although this comes at a cost of an extra $30.00 a pair. This is the excerpt from their website:
"For perfect pair matching, tweeters are broken in with 24 hours of pink noise, while woofers receive this along with 24 hours of a 25 Hz 1/3 octave warble tone. Perfect pairs are matched to within ± 0.5dB and provided with anechoic 2pi frequency response and free air impedance curves. Woofers are also provided with T/S parameters."
Their crossover components are matched to within 1% tolerance. These are mainly for DIY kits, but it is a nice touch.
