So I set everything up just to hear them in my room. Placed them with the mouth facing the wall behind them, 19" from that wall. With my SVS subs the auto calibration had set my subwoofer output at -1.0dB so I just left it at that just to see how it sounded.
I've read that the THT isn't considered a true horn sub but it's the closest to one I've ever heard. It's really hard to describe how they sound. They're just plain violent, but in a good way. Just unbelievable output but they don't feel or hear like they're straining whatsoever.
I put on Star Wars IX and watched the opening up until Palpatine raises the star destroyers. It felt as if my couch was levitating along with the ships! Then I looked up some old school Bass 305 songs on YouTube. My best friend and I used those songs back in our car audio days. By far the cleanest and smoothest that I've ever heard the bass from those songs.
What is noticed most is the evenness in output at all the low bass frequencies in the Bass 305 songs. With any previous home sub I've had there always were certain frequencies that were over emphasized and certain frequencies you could barely hear. I don't know if it was a combination of sub placement, the subs themselves or what but I think I got lucky with these THTs and how they interact with my room because to my ears they have the flattest response of any sub I've never had. And that's only messing around with them for a little over an hour.
If you have the room and if the gigantic size isn't an issue I would highly recommend a THT or similar sub! 🤘
