How do I verify this is the correct size?
Measure the internal diameter of your existing voice coil. This 74.5mm model is typically used in drivers with a 1.4-inch to 2-inch exit throat.
Is it difficult to align such a large coil?
Due to the precision-molded frame, alignment is straightforward. However, with a coil this size, it is critical to ensure the magnet gap is perfectly clean using adhesive tape before installation.
Why are spring terminals better?
On large-format drivers, spring terminals provide a constant, high-tension connection that won't vibrate loose, unlike standard spade connectors.
