It was purchased with the intention of upgrading to something better and more powerful than a JVC I had, the 150 watt. I use it with a mono 400 watt amp. In terms of power, it's fine for a 250 watt speaker, but in terms of bass quality, it's unacceptable, terrible

I didn't even get to listen to it for 5 seconds, it played and burned out. Spend a bit more to get something decent. It had been set with an oscilloscope for the amplifier to deliver 244 watts

It's worth every penny and even more; I have it in a 35 L open-top box and I am very satisfied. I wholeheartedly recommend it with my eyes closed!!!

It's decent for its price, quite powerful and relatively clear (for a speaker that costs 60 euros). I have it paired with a Sony Xplod 300W RMS from the dinosaur era and it plays just fine.

Plays very well, shakes the whole car and I have only installed one and my box can fit two. If I change the box and create one with a larger space, it will play even better. I can say that it is worth the money and I did not expect it to play like this.

Very good value for money! I drive it with an Alpine amplifier 2x250rms (bridge) and it helps both JBL speakers, but the oval 6x9 93db, and it gives me quite pleasant moments of sound. However, because I like the massage, I will probably go for the 2kw.

Guys, the bass is very powerful to the point where you can't handle it indoors.. I play it with the 600.1 and I have it in the 41L trf box and it rocks.

I didn't even struggle with it within a week and it burnt, it's a shame. It's better to spend an extra 50 and get something better

I have had it for 1.5 months with a 4-channel at 2Ohm 250rms with a 50-liter box with double bass reflex and with a source that reaches Volume 63 and I play the intensity at 35-40, I did not expect it to produce such powerful and clean bass. I highly recommend it

I have installed it for about 3 weeks in my car, connected to the four-channel amplifier TRF M.600.4AB. The speaker really rocks, I never expected it to have such powerful and clear bass! Imagine, it can be heard up to two blocks away, and I have even reduced it by 8db from the source's app. It doesn't perform as well below 30 Hz, but for its price, I think it's the best. I have placed it in a 70L (57L net volume) open-type box of my own construction, with a type G labyrinth (also known as a bass reflex subwoofer box), and I have set the gains on the amplifier using a multimeter (the gain indicator is set at about halfway). So far, everything is perfect, but time will tell if the purchase was really worth it.

I play with the TRF amplifier at 200 rms and in the TRF 41L open-back cabinet, it has excessively powerful bass

I have it for about a month with a fairly large closed-type box and it plays very well and I did not expect it, I highly recommend it, it's worth its money...

Quite powerful for its size in a fairly large box. I have to say it plays good bass with a sealed box, but with ventilation it plays more punchy. It's worth its money

I have been dealing with car and home speakers for many years. This specific speaker, with a closed box of 45 liters, plays incredibly loud and clear. The amplifier I use is a 4-channel KENWOOD with bridged 2 channels, so it plays at around 200 rms. IT IS WORTH ITS MONEY AND ANYONE INTERESTED IN GETTING IT WILL NOT LOSE.
