Subwoofer Speaker Basket Frames form the backbone of any loudspeaker build. Our selection ranges from 6.5″ to 32″, covering small drivers to oversized custom subs. We offer two main styles: stamped steel frames and cast aluminum frames. Steel frames provide a budget-friendly option, often used in entry-level builds. Cast aluminum frames deliver superior rigidity, better heat dissipation, and long-term durability. Each frame keeps the cone, spider, and motor in precise alignment, even under heavy excursion. By choosing the right frame, you balance cost, strength, and performance. This ensures your subwoofer delivers consistent power, accurate sound, and lasting reliability.
