Review: Great Enclosure - The craftsmanship of the box is great. All the carpet is well attached, and it is well sealed. Opening was a little tight for the RE Audio REX-8s that I put in, but they fit after some "persuasion". The speaker wire that comes pre-installed is junk (like 18-20 gauge), but it's easy to remove the terminals and attach some nice wire. After I lined it with polyfill it sounds great. For the price you just can't beat it.
Review: Great sturdy box. Impossible to build a better one for less $, or as fast, than you can buy one from SycoSound. Had it in 2 day - Amazing construction, and really fast delivery. I was going to build my own box, but I couldn't do it in less time, or for less $ than this box. Good sturdy box, carpet on the outside is really well applied (better than I think I could do it) and the connectors seem great to me. The box has 2 separate compartments, one for each sub. I'm mounting it in the back Passenger side of an FJ where the plastic sub box normally lives. It fits there quite nicely with the narrow side down and wider side up.

### ⭐⭐⭐⭐⭐ Great Enclosure

### ⭐⭐⭐⭐ useful and solidly built
*by C***S on September 26, 2012*

I got this speaker box to test an idea I had for a small guitar amp. I found a set of Peavey 8 inch guitar speakers on sale very cheap, added metal grills, and planned to use a Lepai T-amp driven by my Behringer Vamp 3. LP-2020A+ Lepai Tripath Class-T Hi-Fi Audio Mini Amplifier with Power Supply 8-Inch 2-Piece Steel Mesh Speaker Grill - Black Peavey 8" Guitar Speaker 4 Ohms 70777082 Behringer V-AMP3 Next-Generation Virtual Guitar Amplifier with USB Audio Interface And Energyxt2.5 Recording Software I was after a small amp that would have good bass response, and it turned out fairly well. Obviously, while you could also use this rig for mp3s and such, the frequency response will not be anywhere near regular stereo quality. Again, obviously, this box is designed for woofers or sub woofers, and is not tuned properly for the best tonal quality for my use - but this was an experiment, and I was not looking for perfection, just usefulness. The box itself is MDF (not hardwood, as the copy claims) with very strong carpet glued to the outside of the cabinet. It has separate terminals for each speaker, and each speaker is isolated in its own compartment. The box is sealed and glued well, and feels very solid. There are lips on the ends which make it easier to move and carry, and I decided not to add the handles I had planned. MDF is common is speakers these days, but I don't really care for it. It is basically a form of particle board made with very fine wood dust, and while it has many useful characteristics, it also has some failings - screws don't hold as well (you have to use sheet metal or special screws, regular wood screws won't work), and edges chip off very easily. I found I had to cut away the carpet before I drilled for the screw holes or I would get melted carpet fibers clogging my drill bit. Cutting away the carpet, I found it very easy to chip and break the MDF around the speaker holes, and had to be more careful and take more time than I had planned. I also would have like the speaker wires inside to be about 6 inches longer, as it was a bit tedious to solder the wires to the speakers with them balanced carefully in the holes. The wires are a good large gauge and tinned for soldering, which is nice. On balance, I have to say I am very pleased with this box, and I plan more variants with Carvin Neo drivers and different amps. It made for a quick practice amp for guitar, and although the Peavey speakers are not the greatest, with the proper preamp or guitar processor, I am happy with the sound, given my expectations. I would definitely get this again, and intend to try others in the same line, at least for my uses. It would be fun to build a "stack" of these to see how it would work. I am also thinking about using one of the boxes similar to this to house the amp, for a more finished look. I plan to include some pictures with this review. I did not try it as a woofer or sub woofer box, so can't comment on that.
