| | Posted: | | | | I am looking for a TV stand, but i am having trouble finding what I need. I have L890 mains (these are huge), so I can't put much beside the TV. My subwoofer has been off in a corner and I think it would sound better under the TV because it is noticeable that it way off center.
The TV is 47". I may get a 50" or 55" soon. Ideally, I'd like something about 30 inches high, at least 18 inches deep and about 48 inches wide. It would be mostly open on the back and have a shelf 9-12 inches high below the part where the TV sits where i coudl put a receiver, then be open to the floor below that. There is a furance intake near the center of this wall, so I can't set anything directly on the floor. If I do get a cabinet with legs or put one up on blocks, I'm wonderind what setting a subwoofer in the cabinet itself will do acoustically. |

| | Posted: | | | | I can tell you from experience that placing a subwoofer in a cabinet is a big no-no especially if it is ground firing. A sub should be placed off to the side and, if properly set up, you really shouldn't be able to tell exactly where the sound is coming from  . Have you ever considered a wall mount? I don’t have pictures of my set up but I have my 42” Plasma wall mounted on a Sanus Full Motion Articulating Wall Mount that can easily handle up to a 50” HDTV and my Center Speaker, Receiver and PS3 on an OmniMount 3 Shelf system below that. All of the power cords and cables are pretty much hidden with the OmniMount system. I say pretty much because they do show from the TV down to the OmniMount and then from the bottom of the OmniMount to the outlets. Here are pics of the Wall Mount and the OmniMount Shelf system.   | | | | My WebGenDVD online Collection |

| | Posted: | | | | I can't wall-mount because there's no wall behind the TV. Most of that space is a doorway. The sub is front-firing, though. |

| | Posted: | | | | I agree with 8ballMax. Dont put your sub in a cabinet. I have my on the other side of the room under on of the end tables and due to the furniture you can see it. The base sounds like it coming from all over the room. Try an open type shelf with some glass shelves and a mount for the TV, like a wall mount. Walmart or Target or maybe Meijer would have these stands.
The furnace outlet in the back would be a major concern with heat. Receivers, as I'm sure you know, can get hot and overheat. |

| | Posted: | | | | It's an intake, so no heat worries. I just have to not block it. |

| | Posted: | | | | I agree that it's not wise to put a sub in a cabinet, as that might create all sorts of resonance and vibrations. |

If I do get a cabinet with legs or put one up on blocks, I'm wonderind what setting a subwoofer in the cabinet itself will do acoustically. If the subwoofer isn't properly touching the floor, you will not get the proper resonance from the sub. Have you considered that it may not be the location as much as the flloor contact. Do you have carpeting under the cabinet? Is there anything impeding the cabinet from making solid contact with the floor underneath? I had a friend that had issues with his sub cabinet. He had it on a carperted floor. I purchased four spikes for it, and mounted them. Now the spikes make contact through the carpet and physically touch the floor. It doesn't matter where he sets it now. Subwoofers should provide a "feel" more than the sound itself... Charlie |

| | Posted: | | | | Also, your L890's, You may consider setting them on spikes also. The lower frequencies of those, should be "Felt", and proper floor coupling would help that to.
I must ask, the L890's have a response of 28 to 40K. If you couple those to the floor properly, your base response should be fine. If you are not cutting off your subs at about 40Hz, you may be competing for the LFE with your mains (basically sending two sets of vibrations into the floor at different times, depending on length and quality of cable). Check the specs of your sub & Cabinet. If you are not down to approx 10 to 12 hertz and cutting off at about 40, your sub is adding no benefit.
