the box pro TP218/1600 A

I own 4 of these, I have used them for a few years now.

I have literally caused structural damage with 4 of these in a club 2 each side. They are definitely the number one active double 18" bass bin for the money and I haven't seen or heard anything come close for the price.

I own 8 of the Achat 118a horns but they have a totally different sound to these playing better in bigger venues and outside. These in a medium sized room are extremely effective and you don't have to pair them up or play them in groups like a horn box.

For a larger room you will need more then a pair as they have a weird cut out feature when they clip, the Achat or single TP118a boxes don't have this feature but judging by the size of the amp on this box I can see why, its almost double the size! It is a good safety feature to have but I find sometimes they clip and the bass goes for a bit too long while the Achat or single TP keep going. Sometimes just as the bass gets to a sweet spot the limiter will kick in and the box goes into limit mode for a few seconds. With the other boxes you can hear when they clip and know to back off the bass a bit but these boxes just cut themselves off.

This feature can be good if you leave your sound unattended but I would rather set limiters myself on my speaker management system or Digital mixer. If I know a venue is big I always carry 4 or just bring my horns instead.

These boxes have the best handles out of all of the box pro range. Lots of steel bar handles so they are easy to carry and move about with another person.

A very good box, These must be the most sold Box Pro active speaker as everybody has them now. They are definitely an impressive box but don't push them too hard or go too crazy, add more so they can play more easily, comfortably and avoid clipping.

I had calculated the size of this cab before it arrived but I was still shocked at the size of it. It is a monster of a speaker, but put our the volume it does it needs to be a big cab. And it really does put out the volume. By getting these you are really stepping up into the big boys territory without the big boys toys prices. This a seriously powerful sub. The controls on the back are a very minimalistic ser with a heavy duty Rocker switch for power and 2 dials. The volume control and the frequency cut out adjustment. Unfortunately these are not normal dials but they have to be adjusted with a small screwdriver. Only a small thing and to be honest once set you probably won't adjust. There is also a phase switch on the back if you are using multiples close together to prevent cancelling out. Overall I am very impressed with these cabs and they are the most powerful subs I have owned. Just not sure if my Tops are up to it now so might be buying some more tops soon.

I have a first-hand experience using the Box Pro TP218/1600A, and I must say, it has far exceeded my expectations in both performance and reliability. As someone who has worked with various sound systems over the years, I can confidently say that this subwoofer is in a class of its own. The difference in sound quality and depth was instantly noticeable from the moment it was integrated into my setup. The clarity and punch it delivers in the low-frequency spectrum are outstanding. Whether deployed in an indoor venue or a large outdoor space, the TP218/1600A performs with consistent excellence and maintains sonic integrity at both low and high volumes.

One of the most impressive aspects of the TP218/1600A is its sheer power. The dual 18" woofers provide an immense output that fills even the most expansive venues with tight, controlled bass. Unlike some subs that sacrifice definition for volume, this unit manages to balance both beautifully. It doesn’t just produce loud bass, it delivers rich, musical low end that complements any genre, whether it’s electronic dance music, hip-hop, rock, or orchestral soundtracks. The transient response is fast, and the low-end extension is deep enough to shake the floor without introducing muddiness or distortion. It handles dynamic shifts with remarkable ease, and its ability to reproduce sub-bass frequencies with precision is one of its greatest strengths.

Importantly, its durability and build quality are also standout features of this model. The robust cabinet design, combined with the reinforced grille and solid handles, makes it ideal for touring and frequent transportation. I’ve used the TP218/1600A in various demanding environments, including live concerts, corporate events, and club nights, and it has proven to be both rugged and dependable. It handles the rigours of setup and breakdown without showing signs of wear or compromise in performance. The internal amplifier runs cool and stable even during prolonged use at high SPLs, reflecting a well-engineered design meant for professional use.

What also sets this subwoofer apart is its seamless integration with other PA components. The built-in crossover and straightforward connectivity options make it easy to align with tops and other subs. Whether I’m using it in a mono or stereo setup, it blends smoothly into the mix and enhances the overall audio experience with authority. It also responds well to fine-tuning and EQ adjustments, which allows for optimal performance in different acoustic settings. Its versatility is a major advantage, allowing it to be used in everything from intimate gigs to high-energy festival stages.

In summary, the Box Pro TP218/1600A is a high-performance subwoofer that delivers premium-quality sound, exceptional durability, and professional-grade reliability. It has become an indispensable part of my audio setup and has impressed both clients and audiences alike. The impact it brings to live performances and events has elevated the standard of my production work. I am planning to buy more. I will continually recommend this product to anyone seeking robust musical productivity...

We bought this subwoofer being a little sceptical after reading some bad reviews about it, especially about the clip protection.

After unboxing we were really surprised by how good the build quality was. Very nice and sturdy handles wich lets you carry it in many different ways, lots of mounting points, and a solid grill.

The amp has a big heatsink with a fan that cools it continuously. People have complained that the fan is noisy, but its really not. You can easily talk over it, and its not disturbing at all, and what do you really expect from an active PA subwoofer.

Now to the sound.
We played it at medium levels for a while just because of old habits with new speakers, and we were impressed at even the lower volumes.
When turning it up we were shocked by how loud it was, and that includes my neighboors.
I got my first noise complaint ever.
The subwoofer sounds very controlled and punches real hard.
It falls of around 34 hz, but that is to be expected from a PA subwoofer.

We have tested it in a big barn of around 100 square meters with tall ceiling, and it fills it up good.

We have not had any problems with the clip protection as people mention, maybe they fixed this, or people just expect subwoofers to continue to play when clipping, but we have yet to hit the clip protection.

One thing that i am not 100% happy with is the coating on the sub, it seems to chip of easier than i would like. I would not mind paying a little bit extra for a new version with a better coating.

But all in all a great subwoofer for the price, you cannot beat it. User friendly, really good bass and good build quality. A solid 8.5/10.
