Sonic Sub Box: 1SL10-0.7 (Gray)

The box was sturdy and well made. I put a JL W3 with the MTX XD600 driving the sub and I've had no problems with the box. The sub is about to shatter. Go MTX

Price is unreal...

Just from the cost side...it would cost me more just to buy the raw MDF from H*** D**** than it cost me to but TWO of these boxes. The boxes are made very sturdily and my MTX 6000 woofers fit in the cutout like a glove. I bought a bag of polyfill also and was able to line both boxes quite well with some left to spare. SE's polyfill bag has ALOT of stuffing! Thanks, SE.

Soild box for the money!

Very well built box. Doesn't feel cheap at all. Obviously not as soild as 3/4" MDF from Lowes, ect. , but awesome for what it is. Can't beat the price. Needed something quick and I'm very satisfied with my purchase.

box

I had one and I am listening music from it. GOOD BOX AND GOOD PRICE

This is a Nice Box

Got this as a fast temporary box till I made one but it sounded nice so I kept it

Great, flexible sub box!!!

I got two of these to replace a ported box i had that was falling apart...soo glad I got these. They were packed well upon arrival, and have sounded great under all kinds of weather conditions...with all kinds of genres(metal, rap, jazz).
I highly recommend this box. If you want tight, accurate but still big sound out of your 10 inch..get this. also..the cup terminal is def. decent so that was a nice surprise.

good box for cheap

The box isnt bad. But i did fiberglass the inside to add strength. I'm happy with it

sonic .7 box

Used with a MB Quart DWI-252 10" sub. Sounds great and is well built. The terminals are nice as well. This is a high quality box for a very low price.

Great deal, needs sealing for best results.

This box is very sturdy and well built. My only recommendation is to recaulk the seams as it was very light on my box. Other than that I'm very satisfied with this sub box.

its a box

This box works great for a Cerwin Vega 10" sub I have in my Lexus.

Very pleased

Well built box - Excellent for the price! Easier and cheaper than building your own.

sonic .7 sub box

used this box with a mb quart 10" dicus sub.it is well built.is also 3/4 " mdf not 5/8 like most.the binding post are well built as well.good value for the money.

awesome sub box

This is the best built box for the best price and i would highly reccomend anyone looking for a sub box.

Great value!

This sub box was amazing it made my one 10 hit really low and it made it sound very clear and loud. I would recommend this box to anyone who wants nice deep bass!

Perfect fit in my Mustang

An excellent quality enclosure. I had to widen the cut out about 1/8 of an inch but it was pretty easy with a Dremel and sandpaper. Top quality connectors

quality build at a great price

I couldn't build a box easily so I opted to buy a prefab despite the naysayers. The inside comes with male plugs which I soldered the sub speaker wire to. The outside is gold plated slots for banana plugs but I just ran the speaker wire in and screwed it down, easy to remove. Nice build. Terminal is quality and after banging around with my fishing equipment and groceries and the million people I drive to the airport it holds up well. I bought a handle for when I have to take it out. very satisfied. I have a jl 10w0v2 and it hits hard and deep. I used 1/3 lb polyfill to smooth out the bass as it was a bit punchy on some R&B and reggae tracks. would definitely recommend.

Great box for my 10!

i highly recommend this company. good delivery time, good product!

compact size

This is a small yet adequit size. I have this with a JL 10W6 and it works great.. love the small size yet able to perform well

great product great price

I purchased this product for my wife's truck and they work great very well built I would recommend this product to people looking for a good sound and not a lot of space to work with.

Worked out great!

I bought two of these for my 10" Sony Xplods ! They were a perfect for the boxesand they sound great !

Sonic Sub Box

Well built sturdy box. Looks great as well. I have a Cerwin Vega 104 in the box and it sounds nice. Rounds out the low end of my music nicely. Not as loud as a ported box and doesn't go as low as a properly tuned ported box would. I would recommend this for anyone who listens to mostly rock and other genres where the bass notes are more natural to the music vs. rap and such genres where the bass goes way low. Thats where a ported box comes in. Of course it is a 10 in a small sealed box, so you cant expect the low bass noted to be real amazing. Overall, im happy with this box.

Great box for the price

A very well built box considering the price paid.
I added more glue around the inside just in case.
Make sure the terminal screws are on tight as my negative loosened up.
Its so cheap that if anything happens I won't feel bad tossing it.

great sounding box

i have it with a P3 D2 sub. it sounds great
the one tiny thing that happened is that one of the nuts came lose on the terminal that holds the wire terminals connections. hence i had to open the box to figure out the issue.
other than that is a great looking box which sounds great with my 10" P3

The boom cube

I recently purchased this cab and was not disappointed. Build quality is good and has nice terminals. I put a Polk 10" and packed it with stuffing and boom. Lows sound great and bass has a nice punch. Great cab for the price!!

Great box

Sub fits perfectly. Nice size of box for trunk. Doesn't take up too much space

Belva 1SL10-0.7

I purchased this box a couple of days ago and it just shipped today. Installed my Rockford Fosgate P3D4-10 inside of it and I absolutely love this box. For $35 this box beats any other pre-fabricated enclosure for the money. Atrend, Metra, and Scosche just can't beat the value and quality of this box. 5 stars and will be purchasing from SonicElectronix again.

Can't beat it for the price.

I had a JL Audio 10W3v3-2 in a JL box and this Belva one has made the driver come alive for me, now I hear the SQ.

Doesn't get much better!

No way you could build one yourself for this price. It's well built, compact, looks good, and does what it's suppose to do.

Only reason to buy or build something else is if you want a custom fit enclosure, or want a box built to the exact spec's of your sub's.

For the other 98% of us, this is perfect!

My sub called for a .83'cu. sealed enclosure and this one is .77'cu.; it's close enough and sounds great!

I bought mine from the "Liquidation" items, listed in "Very Good Used Condition", and saved a couple of bucks. It looked brand new to me, no evidence that a sub had ever been installed, but it did not have any speaker wiring in the box. I had to install a wire between the speaker and the box terminals (not a big deal). Not sure if that's why it was discounted or if they all come that way.

Great sub box for compact areas

This was the only box I could find that could fit a 10” subwoofer in the restricted trunk dimensions of a hybrid car. Fits snug and sounds good with factory fiberfill lining that comes with it. Some of the carpet is rubbing off from pulling in and out which is to be expected

Love this box

I love the tight bass that sealed boxes provide, and this one didn't disappoint! It was a great value considering the money I spent and the features it came with. The connectors were top quality, and the box itself was sturdy and provided great performance!
