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."
David M. The Victrolas Mobile, AL
"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 !!!""
Stevie K. Lake Village, IN
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."

The Engine Behind the System
At the core of the TRC400A is the TRx3118A — a high-output 18” active bass reflex subwoofer delivering exceptional low-frequency extension and system control.
Key Features
Wide Coverage. Focused Energy.
Each TRC400A system includes a pair of TRx3900F column array elements.
Performance Highlights
The controlled vertical dispersion dramatically reduces stage wash and feedback while maintaining clarity and presence throughout the audience.
When ground stacked on a TRX3118A Subwoofer, a TRX3900F Column Array pair creates an 8-foot-tall acoustic aperture, enabling projection that reaches well over 400 feet, depending on environmental conditions. The extended vertical height enhances forward gain and maintains intelligibility across large audiences without the harsh hotspots often associated with shorter near-field columns and point source speakers. Because all eighteen drivers act together as a single acoustic source, the TRC™ array distributes energy evenly from top to bottom, reducing front-row “blare” and delivering a balanced listening experience throughout the venue.
The TRC400A column system features a rotating base that allows the array to swivel nearly 360 degrees, giving crews precise control over horizontal aiming without repositioning the entire system. Each column section can also be rotated independently, allowing the top column to be aimed differently from the bottom to adapt to unique room layouts or asymmetrical audience areas. When both columns are aligned in the same direction, the system maintains maximum forward projection and long-throw performance. When the top column is angled away from the lower column, horizontal coverage increases to better serve wider seating areas—while reducing overall throw distance.

Scale When You’re Ready.
The TRC400A is the mid level TRC system.
Expand your TRC System’s flexibility with purpose-built protection, transport and mounting accessories designed specifically for the TRC Series.
The CB3900L Carry Bag provides padded protection for the TRx3900F during transport and storage. Designed for touring professionals and mobile event providers, it helps prevent finish damage to the DuraTec™ enclosure and grill. Reinforced stitching and durable materials ensure reliable protection on the road while maintaining quick load-in/load-out efficiency.
The CASTERTRX Wheel Set transforms the TRx3118A subwoofer into a highly mobile deployment system, significantly improving load-in and load-out efficiency. Designed specifically for the TRx3118A enclosure, this heavy-duty caster set attaches securely to the cabinet, allowing a single operator to move the 75 lb subwoofer safely and smoothly across stages, sidewalks, and event spaces.
The CV3118A Protective Cover is custom-fit for the TRx3118A subwoofer, shielding the cabinet from scratches, moisture exposure, and cosmetic wear during transport. Ideal for rental inventory and touring systems, the cover helps preserve cabinet integrity and long-term resale value while maintaining a professional appearance between deployments.
The 3900PB Pull-Back Bracket is engineered for suspended installations where column angle control is critical. It allows attachment of a safety steel cable (not included) to “pull back” the TRx3900F to the desired downward angle. This is especially useful in high-ceiling environments or flown applications where precise aiming improves intelligibility and coverage uniformity. The 3900PB enhances installation safety and acoustic accuracy in large venues.
The 3900UB U-Bracket serves dual purposes: it securely connects two TRx3900F column arrays together or functions as a rigid installation mounting point. When coupling two columns, it increases vertical array height for extended projection and enhanced audience coverage. In permanent installs, it provides a stable structural attachment point for mounting hardware.
The 3900SB Swivel Bracket is designed for precision aiming of a single TRx3900F column in permanent installations. It provides up to 27° of vertical tilt (up or down) and 67° of horizontal swivel in both directions, allowing accurate coverage control in reverberant or asymmetrical rooms. Ideal for houses of worship, conference spaces, and performance venues, the 3900SB enables focused projection while maintaining the column’s clean aesthetic. Heavy-duty construction ensures secure mounting and long-term reliability in fixed installations.
