Question: How tall is the space directly under the tv?  Need to fit a center speaker in there..
Document: Replaced a janky home made stand, beautiful change!! Very easy to put together as well. The shelf under the tv and above the doors easily holds a center channel speaker.
My tv is mounted but I needed something to hold the a/v components and center speaker. This was a great piece of furniture for the price. It's obviously not solid wood for this price but it has a really nice wood grain laminate on the mdf or whatever material they use. Kind of a rustic look, it looks very nice. Instructions were easy to follow, and it didn't take me too long to put together. Feels very solid once together.
It looks good and and is strong I have 47 inch lg tv on it  and it seems very sturdy with plenty of shelves for what i need only problem  i had is one of the side bottom pieces was broke at the dovetail joint out of the box i just used flat head screws to reattach the broke piece no big deal it wasn't a major part just decorative overall its nice
This is exactly what I was looking for. A compact, good looking, inexpensive entertainment center whose only job is to hold my flat screen and my components/wires. I didn't need a big piece of furniture.But the best thing about this piece were the instructions. Not only did they have the diagrams, but they has actual written instructions. Stuff like 'put the side with more holes towards the bottom.' It was so much easier putting this together than a piece from Ikea and its cute hieroglyphics.
nice piece of entertainment furniture.could use more space but will work for now.i dident want anything to wide because its in a room.
I am very pleased with the quality of this entertainment center. It only took my husband about 2 hours to put it together. The color is exactly as in the picture. It's very sturdy and the price was incredible!
great looks. plenty of storage. not difficult to assemble. great instructions. price is a good. no great value .need a unit. buy this one you won't regret the choice.
Excellent quality, all pieces were in box, all pieces fit well and there were no obvious design issues. Good job.
This went together easily, no missing parts, no misaligned pieces. When finished it has a really nice look to it. I have older stereo components (taller and deepr than the current versions) so it was a challenge trying to fit them into the cabinet. Had to cut a piece out of the back to fit the receiver in.
This is a solid piece of furniture and the metal accents are a very nice touch. On more than a few occasions with this type of furniture some of the predrilled holes do not line up or the pieces don't fit together properly. This was not the case with this item. Everything lined up perfectly and assembly was easy and straight forward with one exception. I knocked off a star because of the door assembly.
Answer: The open shelf is 5 1/2" high, with a center brace that is 3/4 " wide that extends out from the back 6 3/4" toward the front. In other words, the shelf has an obstruction in the middle that keeps you from putting anything wider than 19 1/4" wide  across the shelf. I have a cable box and a DVD player in there with the brace in the middle. The center brace helps support the weight of the TV on top, and is really necessary, though inconvenient. Hope this info helps. I really do like the unit, have had it for a month now, and it works great for what I needed. I did have to cut out more holes on the back panel for power cords and wires, but they are hidden well. Nice sturdy unit that was easy to put together. Hardest part was getting the doors level with each other.
