I originally bought it thinking I'd keep it. It's a piece for a larger living room, I have Yamaha NS-555 boxes and they were less prominent next to it. The performance is awesome, the sound came from a Yamaha HTT-2067 receiver. The SW setup is truly breathtaking during the film, and with large enough living room queues L/R surprises the unknowledgeable viewer with a riveting performance, by no means cheap. The battles in Witcher have realistically rocked the living room in the family home - if this is what you're looking for, it's a bomb for the money. When you don't have children, without a grid it will look beautiful. My negative is that even with movies and especially with music I had to keep the controller in my hand and tweak something - crossover, volume, bass equalization. It didn't seem to fit with my setup and the music (except for a lot of straightforward EDM songs) didn't have that cinematic wow effect. Considering the size, I would need it to fit with the setup (boxes, receiver, living room) on the first try and I could handle its monstrous size at home (even for a living room almost 9x6 meters). So I had to return it. Don't anyone take this as a criticism, it's pretty subjective. But as a quality device, heavy and powerful. I'm sure someone could tame him: )

This SW is fully sufficient for home theater. In my case I tested it with use in a high end stereo chain where it was to complement the Lowther - Bel Canto wideband horns at a cost of 200.000Kč! Even though it is very cheap SW, the connection was successful mainly thanks to careful positioning in the room, measuring and setting PQ in DSP both on eversolo DMP A10 streamer and Wiim ultra. But for top stereo you would need 2 pcs for L and P channel, because even though the bass is not so directional it is still noticeable. However, with these SW dimensions you need a bigger listening room. I see the disadvantages of this SW mainly in the large investigation. The soundboard is only 15mm DTD but it is reinforced with a baffle. Lack of DSP processor for better settings. A class D amplifier is no miracle and will probably have quite a lot of distortion. But all the negatives are exaggerated by the price which is up to about 11 thousand CZK and for that money it is simply not possible to produce something better. I have returned the SW because I will go the higher quality route but in my opinion 80% of average hifists who need SW for supplementation will be happy and for home theatre I think it will suit everyone.
12 inch transducer
With the right settings, decent and clear bass even for music in a good hifi chain
Very friendly price
Decent surface treatment
ordinary amplifier without DSP
it is not possible to set higher division frequency above 120Hz (for example up to 200Hz)
Very weak chipboard only 15mm
Austerity wherever possible

Great addition to the Marantz Cinema 40, after about 60 hours of playing it gets a completely different sound, it's really powerful. Bass really as per the outline without any unwanted reverberation. For the price, great. Living room 6x5m and set at 30% ( reciever at 0: -) )

Perfect subwoofer, I chose it for a room of 20m2. After the first run I was not thrilled, after about 80 hours of music the sound improved incredibly in quality, powerful bass. I can only recommend it.

Taken with the Klipsch R-800 setup, so it' s 2.1 as a result. The subwoofer is powerful enough to sound a room of approx. 40m2. It is necessary to have well-resolved acoustics, because at higher volumes the bass is already very noticeable (it can be adjusted by setting the gain). It is suitable for stereo and home cinema, especially for movies, it sounds great. I took this top model because it didn' t make sense for me to go for the smaller one. For hifi fans - you need to buy a really thick power cable, the supplied one is just an emergency.

I was afraid to buy a weaker subwoofer from Klipsch, so that it could sound my living room of about 50m2. I must say, I was pleasantly surprised. The sound is so monstrous, you can't have it on full blast. 😄 Great!
