RCF TTS 18-A II Overview

The black RCF TTS 18-A II is an 18" 2800W active subwoofer designed to provide low-frequency reinforcement for A/V system installers, audio engineers, and DJs in outdoor environments or houses of worship, concert venues, and live stage applications. Its Class-D amplifier delivers 2800W of power to the 18" woofer, which produces a frequency response of 30 to 400 Hz and is hyper-vented for heat dissipation.

32-bit DSP processing yields simple adjustment of input gain, delay, and crossover presets. RDNet control via EtherCon I/O allows comprehensive remote parameter control and system monitoring. XLR and powerCON inputs and outputs are employed for straightforward integration with standard PA components.

The TTS 18-A II boasts a sturdy wood cabinet, built-in carry handles, and M20 pole sockets for tour readiness.

Low-Noise Electronics

The switch-mode power supply Class-D amplifier integrates a low-noise, 32-bit DSP circuit, controlled through the RCF RDNet network to handle the clipping limiters, RMS limits, polarity, amplitude, timing, and equalization. All settings, monitoring, and advanced features are available inside the integrated RDNet Networked Management software. The rear-panel encoder adjusts volume, delay, and presets.

Sturdy Cabinet

The cabinet is made of high-quality birch plywood with weatherproof treatments. The sub is stackable and lightweight for easy setup and tear down. The polyurea coating and rugged structure of the cabinet survive long-term use and transportation while the separate housing for the amplifier guarantees component efficiency and reliability. A pole receptacle on top and side allows the woofer to be deployed in various situations.

Hyper-Vented Woofer

The 18" woofer features a lightweight neodymium magnet, inside-outside copper voice coil, and silicon double spiders. In order to dissipate the heat generated by the powerful voice coil, RCF engineers have developed an internal ventilation system with low power compression. The Hyper Ventilation System is the result of a complex combination of ventilation ducts in the voice coil former, in the magnetic structure, and in the woofer's basket. Demodulation rings reduce the harmonic and intermodulation distortion due to voice coil displacement, and as input current varies, the system inductances are more linear. The cone is water-resistant.

Vented Ports

The airflow in the vented ports suffers the turbulence of the air due to the speed of air. The improved vented port is a proprietary solution that enhances aerodynamic behavior of the air, thereby gaining efficiency and reducing distortion.

RDNet Control

RDNet is a proprietary protocol that provides straightforward monitoring and intuitive control of the audio system down to every device and object. Each device has its own DSP, giving the possibility to address presets or parameters specific to single or groups of objects. A network user can change level, delay, EQ, and advanced subwoofer configurations.

      Lasted a day for my dog
      Style: Original, Style: Original
      My dog absolutely loved this toy, but sadly it didn’t even last a full day 😩 I’m not sure if that’s because I have a Rottweiler/Lab mix with the jaw strength of a tiny excavator, or if the durability just isn’t great. Within a few hours, he had already torn right through it 🥲 That said, the sound it makes had us cracking up and definitely kept my dog entertained and intrigued while it lasted!

      Great toy!!!
      Style: Original
      My dog went mental over this ball!!! She will let me roll it through the backyard or in the house and she will go nuts for it but the great part, she will play by herself with this ball. She will roll it and jump on it and just have a blast. Since this is not a normal chew toy, my dog's big, she only gets it when I'm with her. It kind of makes it our special thing when I pull it out. We play every day with it and her enthusiasm has never lessened. She can be in another room when I take it out of the cabinet and the second she hears it, she will run into walls in her rush to get to me so we can play! It really is better than just throwing a ball back and forth. She's completely engaged the entire time it's out. I highly recommend it but just know it's not a normal toy that you can just throw to your dog and walk away. It is an amazing toy to help you bond with your pet.

      Great for dogs that need to stay busy
      Style: Original
      My dog absolutely loves this ball. It is a little noisy so we take it out in the yard and let her play with it there. I highly recommend it if you have a dog that get bored easily. This will surely keep them busy.

      Fun for the Dogs and Kids
      Style: Original
      My dog seems to love this ball. Super sturdy for an aggressive chewer. Easy to play with. Makes the tube sound when it rolls which keeps the dogs attention well. Super fun. It’s made out of hard plastic so it’s not soft at all. Can take this anywhere.

      Best Balls Ever!!!
      Size: Medium
      These are the best balls ever! We have 2 very active ball loving dogs and these bounce very well and they actually hold up with active play and chewing. They still look brand new after daily use for months!
