The Bybee Speaker Bullet Kit have replaced the Golden Goddess "Super Effect" Speaker Bullets. The Golden Goddess Speaker Bullets have been universally praised by audio reviewers and customers, as the most powerful of all Bybee performance-enhancing accessories. However, the combination of costly materials and labour-intensive construction has mandated a retail price of $4,200 per set of four, with two sets required for bi-wire applications. Those original external Speaker Bullets are now discontinued, but Bybee Technologies is now offering a new solution. The Bybee Internal Speaker Bullet Kit, designed for DIY hobbyists and OEM speaker manufacturers, is meant to be installed after the speaker terminals and before the crossover network. The Internal Speaker Bullet Kit delivers equal or better performance enhancement at a fraction of the cost of the original plug-in Speaker Bullets.

Each Internal Speaker Bullet Kit contains 2 Positive and 2 Negative devices (4 in total). The Positive element is a custom-designed "Super Effect" Internal Purifier with one-inch Silver leads. The Negative element is a newly developed device optimized for maximum sonic performance and quieting on the return leg of the circuit.

One Kit will treat a pair of single-wired loudspeakers. Bi-wired speakers will require two Kits. For the audiophile who demands the absolute best performance attainable, a Positive and Negative pair may be installed at each transducer rather than at the crossover network.
