Alpine R2-W10D4 with Sealed Enclosure

Sub Box

I was impressed with the quality of the sub box, I couldn't have made this in my shop for this price. My suggestion would be to change how the wires inside the box mount to the plug.

Can't beat the price

Like the negative review, the internal space is actually 0.70 cubic feet which is the exact space recommended for the NVX VCW10 sub. Ordered it for that reason. Seems very well built. Some sort of hard sealant along all the seams. Although the terminal cup doesn't look sealed. Nothing a bead of silicone won't fix. The only negative I have is that the cutout is just slightly too small for my sub. I'll have to trim it. Which sucks, but it beats building a custom box and it's still cheaper than buying the materials yourself. Overall a good looking box.

Excellent box

This is my second Atrend box and won't be my last. Built a lot nicer than most pre-fabbed boxes.

Excellent Box

Everything arrived timely and as advertised. Easy to install and was almost made for my JL10w3v3-2. Nice dimensions that took up hardly any room the trunk. In fact, my wife didn’t even notice that it was in the trunk after it was all installed! I would recommend this box to anyone who’s subbing specs are close to the manufacturer's cubic feet specs.

Perfect for RF P3D4-10s

I noticed a negative review for this enclosure due to the fact that the air space was actually less than advertised (This could be fixed by now. I'm doing this review on mobile so I can't check.) Long story short, I ordered one based on the specs given in that negative review and it's almost perfect specs for a Rockford Fosgate P3 10?. The enclosure is actually the exact amount of airspace needed. I say it's not to spec only because the dimension are slightly different, but I doubt it makes any difference since the airspace is still the exact requirement and it's generally the same shape.

DO NOT BUY THIS BOX!!!

Purchased this box based on Sonic's recommendation. Even asked specifically about size before purchasing. Received the product and was exactly what I feared, the inset sides like in the pic throwing dimensions of a box this small way off. The interior dimensions of this box 12x11x9 isn't even .69 cu ft. Only response from Sonic is "oh well we can only go off the manufacturer specs." I expected better from Sonic.

Atrend 10SQ subbox

Great box! Exactly what was in description. Works great! Good!

Guinea pig review

It seems I'm the only one that bought these from here lol, but you get what you pay for. Yes they are pricey but they are equivalent to infinity Kappa 93ix 6x9 in terms of crisp and clean. These subs are great so far, I bought them about 9 months ago and just put them in. So I can't speak on durability but great wire connectors that's included and the overall sound is great. If you have the extra money, I suggest getting it. I have 2 10's with the nvx 2000 watt amp running in my 71 Superbeetle. I was running a single 400 watt 10 inch Memphis sub with a 400 watt kicker amp, he did his thing and will again in the future. I just wanted to go back to duals in the bug. It's been since my college days. Buy it, only if you have the funds.

Well worth it!

I always been an Alpine man. I went from an S W10D4 to this R W10D4 and I am very happy I did. Bass is nice and on point. I would buy again!
