The TRx3118A is a high-output 18-inch active subwoofer engineered to deliver deep, controlled low-frequency performance in demanding live sound environments. Extending down to 37Hz, it maintains tight transient response and consistent output at high SPL for impactful, musical bass reproduction. Its high-efficiency Class D amplification and precision-tuned enclosure work together to produce authoritative low-end that performs equally well in standalone subwoofer applications or as the low-frequency foundation of the TRC Column Array Systems. Built for touring reliability and scalable deployment, the TRx3118A provides serious, professional-grade bass reinforcement wherever powerful, controlled output is required.
Everything you need is built directly into the TRx3118A—no external amplifiers, outboard processors, or complex system wiring required. Power, processing, and protection are seamlessly integrated for fast deployment and predictable performance.

Customer testimonials across the TRC platform, from the TRC200A through the TRC600A, in real production settings.
"We were all amazed with the tone, clarity, definition, coverage & volume produced from these compact enclosures. Everything about these cabs is stellar. The vocals & instruments are clean & detailed. Coverage & dispersion from front to back, left to right of the venue is even & clear - virtually eliminated hot spots & dead spots."
John H. Boston, MA
"Our 5 piece honky tonk/Western Swing band uses a single stack as mains and monitors regardless of room size and even outdoors up to thousand seats with no volume issues at all. It allows us to mix on stage and control our own finished product sounds much easier than the additional sound man. Several companies make this style of pole/sub combo system but nobody comes close to the clarity and power Carvin offers. We can't recommend it highly enough not to mention the money it saved."

"Recently, my band from Nashville TN called Monsters of Yacht® played at The Country Club of Mobile. We own our own sound and lighting equipment but due to time constraints I decided to hire a local production provider. Lee Abbett was recommended to me by another production company. When I called Lee to hire him he told me about the new Carvin gear he is using and that we would LOVE it as much as he does.. Well, he was right! As soon as we arrived, he fired it up for us and I was blown away by the sheer volume and clarity of the rig. I couldn't believe how much sound was coming from the physically "thin" column array cabinets. From an audience perspective, the arrays accomplished more than just great sound, they also blocked less view of the band than traditional speaker stacks and were tall enough to project over the heads of guests who ended up standing right in front of them. We play all over the country and get to play on almost every line of sound equipment out there. We had a great experience with Lee running the Carvins with this design that was new to us. Lee has great enthusiasm for Carvin gear and it is justified. In fact, this encounter made me regret buying the EV system I picked up last year... I am impressed with Carvin! Congrats on a great product!"

"Hello Carvin ...I just wanted to say thank you for helping me place this order and the sound system is absolutely incredible!!! I am completely blown away!!! I feel like I'm at a festival with a wall of speakers.... our property is 10 acres with about 5 Acres of sand dunes all around our Lake... it's like a big swimming Bowl and Reverb on my property is what I wanted and it's absolutely fantastic thank you so much !!!""

I'm using the Carvin Audio TRC system for DJ and sound production. What I love about this system, besides the amazing sound, is the universal features it can offer, rather than being stuck to one setting. I love the 3 sub pole mounts on the sub for pole configuration and how fast the system is put together. I keep saying this to everyone BEST SYSTEM EVER!! If you're looking for a column array system that's different, this is the system to go for, hands down!"

"This PA is amazing. The load in to Julep Point is almost a mile push, I kid you not! Thankfully having the subs on wheels allowed me to easily push them out to this beautiful location. The power consumption versus output is just crazy! I ran the left side PA and four lights on one 20 amp Circuit and the right was the same. Basically the whole show on two 20 amp circuits. Mind Blown! I can't articulate how much I love this new PA! It Rocks!"
Lee A. Absolute Entertainment Mobile, AL
"Have absolutely loved this system, it sounds awesome, and it is such an ease to set up. We have been 110% satisfied with the system, that’s why we are adding to the system to do outside and very large venues. We play 60 to 80 shows per year and are constantly getting asked where we got the system and I always tell them about Carvin."
Roger V. Kansas City, MO
"Just a follow up to say how pleased I am with the TRC600A array we installed in the Haven event venue here in Birmingham, AL. After 6 months of operation with corporate events, private events, and bands, it is just what this venue needed. Great coverage, sound, and look. The system actually improved the overall acoustical sound of the room due to the limited vertical dispersion. Huge asset! Thx again for working with me & going the extra mile. Always loved Carvin! Rock on!"
Michael P. Alabama Music and Audio Supervision LLC
"We ran the new system last night at a large church to try things out. Everyone was thoroughly impressed. Great coverage in a room that holds roughly 700 people. We will be putting it to good use this weekend for a band job a few hours away."
