The seller responded immediately and got me the damaged part replacements very fast. The parts themselves are amazing though I needed more glue for my particular subwoofer and I also used a carbon fiber dustcap instead of the thin plastic one supplied but I'm 100% happy! ### ⭐⭐⭐⭐⭐ I love this product!!! *by B***N on May 28, 2016* Ok so those of you that are knowledgeable about subwoofers and kicker fans alike let me tell you that this is a great product. I had a kicker L3 15 with a blown voice coil. I took it apart to find out what size the coil was and was able to buy this one to replace it. It was easy but time consuming and the and result was a kicker L7. I love this product and encourage anyone how wants to fix their kicker. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/15039163-springfield-speaker-2-58-subwoofer-coil-replacement-kit-dual-4](https://www.desertcart.pl/products/15039163-springfield-speaker-2-58-subwoofer-coil-replacement-kit-dual-4) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-22*
