(2) Alpine R2-W10D4 with Ported Dual Enclosure

Great value

I have 2 10 inch nvx vsw104 and they sound very good and the box seems to be made very well

Great value and price

Good solid well built box great price it's better value then building it it works great with my soundque HDC3 10's had to trim out circle a small bit because the HDC3 10's are a little bigger then normal tens but worth it like said great value on box saves time and money building one you can't beat it

Dual 10" vented sub box

Very sturdy and heavy, well constructed, and everything went together with ease. The only drawback is that the speaker connections are on either side instead of the back, which made it more difficult to wire my DVC subs to a mono amp: excess speaker wire used and the wires show and may get caught up on things.

Good product, good oricd

Box was made well if 3/4" mdf and corners were sealed nicely. Carpeting was done nicely and the box terminal was a step up from the super cheap plastic crap.

Atrend 10DQV

Right volume for Alpine Type R. Insulate with batting. Add a bit of polyfil. Sturdy. Well built.

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.

Perfect size and perfect fit.

I chose this box for my two Rockford Fosgate 10” P3s. It has the exact manufacturer cutout size recommendation of 9.13”
Very happy with the condition and quality. Definitely got my money worth. Should last for long time. Very affordable. Proud of the quick service and knowledgeable communication.

Great sounding subwoofer

I wanted some better low end in my 24 VW GTI. I also wanted to keep some room in my hatch. This Alpine sub worked out very well. I have it in a .65 cubic foot enclosure that still leaves me plenty of space. It sounds great too. It’s punchy and goes deep. Provides more than enough bass for my needs.

Great Sub

Very happy with this sub. Durable and able to deliver, sound quality is really good and decent low end for a 10” sub. Would purchase again
