Hands down, I was there yesterday at NAMM—it was insane! The demos were next-level. This setup isn’t for the average listener—it's on a whole different plane compared to even top-tier systems. David is absolutely wild! The kicks hit so low and hard, you can literally feel your blood moving through your chest. It was unreal… I’m still dizzy from it! 😂

Idk what the full-ranger in the middle is, but I feel like 18HTX100 has entered. And, I have to say, this is probably the most exciting production speaker design I’ve seen yet. Well done!

This is a wonderful equipment for DJ! It is playing the low range that can not be compared with other subwoofers. It surpasses Martin’s triple 15-inch woofer and two 18inch L-Acoustics subs. I can listen to the sounds that I could only listen to at the concert venue in my room. My friends call me crazy, but the music is asking for it. (Translated from Japanese by Google)
