Speakers have + - to wire to. **Q: How does music sound? Can I build a boombox with two of these speakers?** A: These speakers are tweeters only for high frequencies. They sound great but you’ll need a mid range speaker and woofer for overall performance. **Q: How can I make a speaker with these and what would I need?** A: These little speakers are best suited as replacements for the elements in high-quality earphones. To use as an independent speaker, you would need to mount them in an enclosure. Be aware of the power limitation of 3 watts. **Q: Are these “waterproof”? i need to replace one of the speakers in my ijoy speaker. they look the same as what i have, plastic cone, etc.** A: These speakers are definitely NOT waterproof. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by V***8 on July 21, 2025* ### ⭐⭐⭐⭐⭐ Review *by B***D on October 11, 2025* ### ⭐⭐⭐⭐ Review *by D***N on December 31, 2025* ## Frequently Bought Together - Gikfun 4Ohm 40mm Diameter 3W Full Range Audio Speaker Stereo Woofer Loudspeaker for Arduino (Pack of 2pcs) EK1794 - HiLetgo 10pcs Micro USB to DIP Adapter 5pin Female Connector B Type PCB Converter pinboard - waveshare 2.8inch Screen LCD Compatible with Raspberry Pi 4B/3B+/3B/2B/B+/A+/Zero/Zero W/WH/Zero 2W 480×640 Resolution DPI IPS 5-Points Capacitive Touch Control Optical Bonding Toughened Glass Cover --- ## 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.jp/products/41740619-gikfun-4ohm-40mm-diameter-3w-full-range-audio-speaker-stereo](https://www.desertcart.jp/products/41740619-gikfun-4ohm-40mm-diameter-3w-full-range-audio-speaker-stereo) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-07*
