  • Competes with skars mid-high line of speakers for a fraction of the cost
Size: 15 Inch Style: Dual 4 Ohm
I purchased the BSF 15" 4-ohm subwoofer and am running it on a 2000-watt Taramps amplifier at 4 ohms in a Harmony Audio 15-inch enclosure. For $139, this subwoofer performs far beyond what I expected for the price. I own several vehicles and have experience with a wide range of subwoofer setups. I’ve run Skar EVL series 8s and 10s, a 12" VXF in a large enclosure, SVR model 15s, and multiple NVX 15-inch subwoofers, including the higher-end carbon fiber models. Based on that experience, I can say this sub competes surprisingly well with many mid- to high-tier subwoofers that cost significantly more. The bass is strong, deep, and controlled. It hits hard without crossing into the point where the bass becomes overwhelming or muddy. In terms of sound character, it sits somewhere between the musicality of the Skar SVR 15 and the deeper, more authoritative low-end of the Skar EVL 15. For the price, this is an excellent value and definitely worth considering if you're looking for solid output and good sound quality without spending a lot. Great job on this one. ... show more

I've been in car audio for almost 30 years and had used many brands and types of subs in many different vehicles and having seen these with a promotional price of $78 my curiosity got the best of me. I have them in 1.25 cubic feet per sub sealed enclosure and even though I'm still in the break-in period, they seem to hit very well. tight punchy bass that peaks at a little higher frequency than other 12s but I believe thats due to the enclosure.

  • Good Sound, Horrible Quality, you get what you pay for
Size: 12 Inch Style: Dual 4 Ohm
The media could not be loaded. I Bought the sub in Jun 2024 to replace a Kicker CompR out of a Loaded Enclosure where I had Blown out the subwoofer due to shorting both voice Coils, I was recently new to the subwoofer game, since I had just recently bought a New amplifier a AudioControl LC-1.800 from Best Buy I wanted to pair it with a Subwoofer that could handle its Wattage, so I found this in a video review from Wilson Audio and though it might be a good cheap candidate, first couple of months of use and It started to show its first signs of cheap af construction, the surrounding edge where the rubber sticks to the aluminum basket started to separate due to the screws pressing directly into it and it occurred on al 8 holes, had to use a 2 part epoxy to put it back together, fast forward to the last week and I started to smell like burned chemicals coming from my trunk, once I open it, smoked came from the subwoofer enclosure port, good thing I had my toolbox on the car at the time to get the subwoofer driver out of the enclosure and more importantly a fire hazard out of my car, went to the nearest pothole with water that I could find and submerged the motor assembly into it, it was steaming hot, after the water, it didn't even cooled off , after I arrived at home and took a closer inspection, the coil overs where loser in the cavity and appear to have tear out of the Voice coil assembly cylinder where they wound it around, I really wasn't expecting to be a $400 subwoofer but to had perform so cheaply in the construction and the wattage rating didn't even pass my mind at the time i bought it, basket really fells solid and of good quality, I believed Ive has seen it in American Bass Hack line up as well as the driver color but I would Expect different quality from them, Probably just high hopes since at this point I don't believed any sub is made here any more, all chines crap, don't know if the other manufactures might use different adhesives, better quality at least, or their own voice coils assemblies but at least this one product really let me down, for $150 you get what you pay fro the paper cone, spider and basket might be worthy of a 1600W sub but adhesives and voice coil I wouldn't pair it with an 800w Amp, probably a kicker CXA400.1 that I had before could have been perfect with this, I might try to get the cone and voice coil out to se if I can repair it with a voice coil repair kit but even that is spending 80 to 100 bucks to repair a $150 sub, it appears not worthy at all but will keep it just In case I don't have anything to do in a future UPDATE... After the review, a representative from Hiyanka contacted me for a refund or replacement, after 4 days of communication I choose getting a new unit, it did took abit longer to arrived than expected but so far so good nothing bad to report on the new unit, I'll keep you updated if it fails again with same setup ... show more

  • Impressive!!
Size: 10 Inch Style: Dual 4 Ohm
I replaced my old 10” Kicker sub with this Hyanka sub and wired it to run at 2ohms. It exceeded my expectations! It took me by surprise at first because I was not expecting it to make that much of a difference, but it was night and day. The sub hits hard and fills up the space in my van nicely. I would highly recommend this sub for anyone looking for the best value for the money and great performance. It also feels durable and looks great too! UPDATE I've been daily driving this Hyanka BSF-10 for nearly 2 years now and it hasn't skipped a beat. Despite what you might hear about budget subs, this thing is still in great shape- no sagging, no weird mechanical noises, and the surround is still perfectly intact. I've pushed it through two full summers and it never gets hot or smells like the coils are burning. It still hits just as hard as it did after the first week, and it's proven to be a really solid, reliable sub for the money. ... show more
