First and most importantly this is not a pair, you will need two! Also it is not a full range driver but comes with a capacitor to block the lows so you can hook it up to a full range signal of you like or use a real crossover. Also horn like these tweeters are awesome for cymbals (crash and sizzle are unbeatable) and brass horns but can be a little harsh compared to a silk dome tweeter so I recommend to use them it to compliment a system with dome tweeters and just turn these up enough to add that sizzle! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Sound amazing and the hard you push them the better they ... *by P***R on Reviewed in the United States on July 3, 2018* THESE thing rock. Sound amazing and the hard you push them the better they sound. I was worried that being 8 ohms would kill to much sound but it doesnt they have a very BRIGHT sound and are a super solid sound and would recommend to every one. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Sound Super, Look Cool *by M***S on Reviewed in the United States on October 14, 2017* Not only sound great but look really cool with the red bullet insert, So cool I did not put a cover on them to show them off. I purchased MTX brand tweeters in the past and this brand is the one I use professionally in my sound system, Highly recommended. --- ## 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.us/products/10959747-mtx-audio-rtx4bt-4-road-thunder-xtreme-full-range](https://www.desertcart.us/products/10959747-mtx-audio-rtx4bt-4-road-thunder-xtreme-full-range) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-22*
