    • Glad I Made The Purchase
first off let me say the people at Hi Fi Sound connection are awesome!!! super easy to deal with. secondly we got off to a bit of a rough start.. the first sub they sent only worked for maybe 5min under zero load.. barely enough volume to move the sub. they said send it back at no cost.. they sent another one.. the second never worked at all.. just made a horrible garbled bass sound until you pushed on the cone then worked fine but only while pushing on the cone.. they said send it back.. I wanted a refund at this point and they said sure! well a mistake was made in the warehouse and a 3rd sub was sent out. they were kind enough to tell me I could try the sub to see if it worked and if it did and I liked it then i could keep it.. if not they would send me another prepaid shipping label.. well today I took the sub to best buy and unboxed it in their install shop and bench tested the sub box.. it sounded amazing!! even the installers at best buy were super impressed with the lows this thing was hittin.. I took it home hooked it up in my sons truck and it sounds awesome!!! for the price of this loaded sub box you cannot go wrong!! I would definitely recommend this sub for anybody looking for affordable 15in deep bass! A+ customer service also... ... show more

The product broke in the craziest of ways I contacted the seller who told me I had to pay for return shipping which was 165.00 through fedex they would t work with me at all and I do not think the speaker is worth 330 dollars

    • Pray your item arrives fully functional !!!
Product arrived defective/damaged out of box. Slightest touch to speaker at dead center presented obvious coil rub. I have been dealing with stereo equipment for over half my life. So I %10000 know how a speaker should perform and what to do and what not to do. If it arrived fully functional it probably would have been a fantastic item. Mine unfortunately did not arrive fully functional. I paid for a new fully functional loaded enclosure and if that’s what I had opened up then I most definitely would not be giving this bad review. Returning item was hell!!!!!!! I would have tried buying another one from seller if the return wasn’t such a big fiasco! Speaker basket is very thin. If handled correctly during shipping and you don’t get sold a damaged one that someone returned due to aggressive package handlers then item is a ok buy for the money! ... show more

    • Box is solid built , sounds good,
Review Image by Robert Marshall Robert Marshall
Bought this to supplement my 12” woofers that are in individual sealed boxes as I wanted more lows. I ended up taking one of the previous 12” speaker boxes out as the 15” woofer and box purchased filled the void. Woofer sounds great, even at low power while in break in period. Item arrived well packed with additional packing support inside box. This heavy box is very well made and very solid. Nice detail on carpet work covering the box. The box alone is well worth the money. Arrived fast with no issues Love it ... show more

    • You're dumb if you don't think this is a good deal
Well I wanted a new box for a different 15 I already had but it destroyed the used box I bought for it. This box seemed good for the price and for an extra $40 it came with a 15, figured I'd keep as a spare and put my other sub in box. Honestly for the price buying to use , this probably gets 5 stars , don't expect a game changer but I'm not fully impressed with my big boy 15 either and it cost alot more. I never even heard harmony sub in harmony box. I removed and went to put my other sub in this box and... it didn't fit in the recessed area, the diameter of the outter ring was barely too big, right when I was about to give up I had an idea and I barely squeezed it in. Then I put harmony sub in old box to test and see if it was sub or box making noise. This sub is rated 450rms, I gave it 1800rms and cranked it. Made a funny sound after about 5 minutes of hammering (but hey I Gave it more than 3 Times the power its rated for) so I turned it down and it sounded OK. And this box isn't hitting as hard as my old one was, but it hasn't started to come apart yet and it sounds alot better, deeper sounding, the other box never sounded like it had a 15 , too punchy and quick, this box gives that low 15 deep long bass you think of when you think 15, I do wish it hit just a tiny Harder. The 4 stars is just because I had to Jimmy my other sub in. For the price this is a great deal. I think I might grab 1 more of these subs and a double box for my other system and see what 2 (900 rms total) would do with 1500rms or 1000 but probably 15.... for the price its worth the risk. Might just pound and be good ... show more

    • Bad speaker frame
It puts out a decent sound. But poor building of the frame. It broke at the magnet and I am pissed

    • Tuned low & sounds great!
I just installed it on my Xterra today, it sounds great but be careful with how much wattage you are putting to it. I've only run it on my bigger sub amp so far which can make around 2200 watts in 2 ohm and the sub got smelly pretty quick when I had it cranked up pretty high.. I'll be running it on my smaller sub amp till I can afford to buy a better sub(I really bought it for the box anyway).. the box sounds great and is tuned really low.. Real glad I got this so far!! ... show more
