Polk Monitor XT12 Powered Sub - 12" Dynamic Balanced Woofer & 100W Class A/B Amplifier, Low-Resonance MDF Cabinet & Removable, Precision-Fit Grille, Dolby Atmos & DTS:X Compatible, Midnight Black

Excelente sub, tiene potencia de sobra para llenar el cuarto y está muy bien tuneado para frecuencias de home theater y música.Lo tengo junto con unos POLK XT5.

A great Subwoofer, regardless of cost!This is a very good subwoofer, solidly build at a very reasonable price, ESPECIALLY IF YOU CAN GET ON SALE. It has all the inputs you need, including speaker level inputs. Arguably this is the best way to hook up your sub, because it gets the same input as the main speakers and then low pass filters it. I have tried this sub with a 35 W rms/ch amplifier and relatively small hi-fi speakers and a 100 W rms/ch amplifier with large floor standing hi-fi speakers. In both cases it really boosts the low frequencies making the sound full, deep and well separated. For starters, set the volume level to just under half and the low pass filter to 80 Hz, listen to a variety of music genres and adjust to your liking. The sound output is deep, musically pleasing and you can feel the low bass notes in your gut!

I was replacing an old, much more expensive Velodyne sub (may it RIP). Not wishing to spend a fortune on one this time around, I opted for this Polk sub. I had some concerns about the quality attainable in this price range, but I knew Polk as a quality brand, and I was pleased with the purchase.Yes, this sub can shake your house if that’s what you want. It can probably shake your neighbor’s house, too, if you turn it up some more. But I was after neither of those things. It was clean and accurate base which adds color to the sound without being overwhelming I was looking for. In fact, from where I stand, if you are playing an audio track, and one can tell right away that there is a sub, it’s probably too loud. Clean and accurate base is exactly what this sub delivered for me.Someone here mentioned that auto-on wasn’t working well. It does work very well for me. Just don’t limit LFE output too much on your AMP. I have it limited to 120 Hz on the receiver to make sure a good amount of output flows into the sub to reliably trigger auto-on. Then I limit the frequency with the sub’s own crossover some more to achieve a perfect balance.If I were to make a wish, it would be to have an LED indicator on the front of the sub to see that it did turn on, like my old sub had. Assuming nothing fails through it is certainly not a necessity and would require an add-on to materials and cost.

Excelente monitor, lo recomiendo… se puede conectar a un amplificador profesional de audio y sentirán los bajos bien definidos!!

Som de qualidade. Caixa muito bem acabada.
