I’m an old school audiophile who appreciates clean bass response with lifelike fidelity. I still use my vintage Adcom GFA 555 II amplifiers with my Martin Logan XT F200s. They run rings around my Klipsch Cornwalls. The Pretium 18” is just what the bass doctor recommended. I want to congratulate my friend Aamir for providing us with such a wonderful product that performs flawlessly. Once I downloaded the app and fired it up, I knew right away what I was dealing with. My friend Michael was there still after helping me take this 150lb monster upstairs in my 28ft x 38ft theatre room. We were sitting about 16ft away from the front stage. We were like two children grinning from ear to ear while the cleanest, most transparent vocals along with relentless subharmonic vibrational vibes filled the entire room effortlessly. I’ve got to get another just for bragging rights even though I don’t need it. It’s Just That Darn Good. Thanks Aamir

Clean pure power with killer look

Super device

This sub is serious and Admir has the lost art of truly putting others first. The service Admir gave during my purchase of two Pretium 18’s and an AT-600 was outstanding. I recommend giving Summit Hifi a chance. You will not regret it.

I recently upgraded to a dual subwoofer setup, and the difference is incredible. The bass is deep, powerful, and incredibly clean without being overwhelming. Having two subwoofers makes the sound much more balanced throughout the room, eliminating dead spots and creating a truly immersive experience.

Whether I’m watching movies, listening to music, or gaming, every explosion, drum beat, and low-frequency effect feels realistic and controlled. The build quality is excellent, setup was straightforward, and the performance exceeded my expectations.

If you’re looking to take your home theater or audio system to the next level, I highly recommend investing in a dual subwoofer setup. It’s one of the best upgrades I’ve made, and it’s worth every penny.

Just got 2 of these subs..All I can say is WOW.
I can't take the smile off my face .They exceeded my expectations by large.. I have tonewinner amps and love them, but was not sure about their subs..
After the great communication with Aamir and watching Spec Of Tech YouTube reviews, from Barrett I was hooked..

I had paradigm ,SVS pb,3000, and JL subs..
To my surprise, this 15" was by far the best sounding and powerful in my house...I can't get over the punch in get, and ultra low deep end..
The sub also looks amazing...Looks high quality ..
I can't thank Aamir enough for educating me these subs and about tonewinner.
I'm a believer now and spreading the word .
If you want killer low powerful bass with crazy mid bass punch, look no furthur...

These subs sound like subs much more $$$$

Thanks again....I'm so happy now with real bass.

I was very skeptical not knowing much about this amp and not finding lots of review videos etc...but I will say I'm impressed with this amp! It works great and the big VU meter looks awesome. It pushes my Martin Logan Motion 60xti's and the 50xti center channel to breathtaking levels.
