Subwoofer is built well, nice and heavy . Have two of them running on a taramps bass 5k at 1 ohm. I feel they can take quite a bit more . But the sound is nice , the enclosure I have them in is 13cubic ft ported with 15” diameter octoport.. tuned to around 32 hz . Overall I’m happy with this purchase ... show more

I bought a single 18" and built a box for it and this subwoofer SLAPS. Very well made sub with a big heavy magnet, especially for the price. Running it with an American Bass 2000 watt rms amp with half tilt... it moves air and rattles my eardrums along with everything in the car... F.Y.I: Just make sure to buy a professionally made box or really know what you're doing if you make a box. This was my first box i made and within a couple of weeks this sub started ripping the internals of the box apart (ports) so I needed to go back into the box and use heavy duty caulk to fix everything. Sounds better than ever now. ... show more

    • Amazing value, sledgehammer bass

Absolutely stunned by this sub. Hits like a semi truck. I'm powering it with the Skar 4600 for plenty of ceiling in terms of power. I would definitely get a big effing amp if you want to run this properly. Make sure you get a quality cabinet built custom for it or know what you're buying. I am blown away at the quality and sound for the price. Would definitely recommend this company to friends. ... show more

I got my sub a day early, it was double boxed and came with screws. I am impressed with the size of this sub and the quality of its built everything looks solid for the price. I made a sealed box @ 6.25cu' (5.76cu' after displacement) it sounds ok but I'm going to port it after I break it in. I would buy this sub again ... show more

Amazing subs Harmony Audio And super nice price to. I would say there underrated rms because they are built so well. I absolutely would recommend these subwoofers. What caught my eye was the position of the large foam surround and the huge 10 inch tensl woven spider. To me that said huge excursion. And sure enough I was right. ... show more

At first I was a bit skeptical, but don’t hesitate, it is a well built sub. I have a 2700 rms nvx pushing it and it can withstand a beating.
