    Here it is with the grill sitting on front. My plan was to install 4 threaded inserts, one in each corner and use nuts and bolts to attach it. But I like it without the grill so I left it. The grill was custom so it sits until I decide to trash it.

    Should read "I am NOW using a Crown XLS-2502 for power"

    Also, since the build, the plate amp failed. The plate amp is also no longer sold. Parts-Express accepted it for return but that left me with no amp and a big hole in the back, 2 holes actually. I made a wood plate to cover the entire back, painted it black and sealed the back up, cut a new...

    So it's been a few days with my Dayton 18" UM18 in a 4 cu ft sealed enclosure. Power is from the Dayton plate amp, 1200 watt with DSP. The entire kit was $899 from Parts Express. First, everything arrived very well packed and went together really well. I used Titebond III glue for main assembly...

    well, I built one. An 18" sealed kit with plate amp from Parts Express. Came out nice and sounds awesome. Only listened to music so far. Movies coming

    Dual opposing 18" drivers is an option. I have room for almost a 2x2x2 ft box, 8 cubic feet. But I have room for one, no other places I can really add a second subwoofer.

    Reviews of DIY Subwoofers?

    I see lots of information about building them but really nothing solid as far as a review as to how they perform. I am thinking of building a subwoofer project during this downtime and looking at the Dayton UM 18 in a 4 cubic foot sealer enclosure. Possibly doing 2 of them in a slightly larger...

    Have anyone seen the new LG 86" 86UM8070 set?

    I bought the Sony X850G, still unable to view the LG even though retailers have it in stock

    Bi-Amp and Tri-Amp Applications

    I bi amp my Vandersteen 2Ce Signatures. The speakers seem to be set up for it and I realize greater, tighter bass performance. Better imaging and more volume. HOWEVER I cannot contribute that 100% to the fact that the speakers are bi amped. because I use a Parasound 5 channel external amp to...

    Have anyone seen the new LG 86" 86UM8070 set?

    Looking for a big set and this one fas perfectly but I was not so pleased with the picture quality of the older 6570 model from LG. I can get this set for at least $500 less than the Sony 850G and I prefer the apps and software from LG over Sony.

    Broken JM Lab Subwoofer?

    If you can find a replacement driver that is designed to work in the size and type of enclosure, replacing it then becomes rather easy. I would start by taking out the driver and looking for a model # on it and search for a new one of the same model.

    86" LG or 85" Sony 850 series?

    Thanks, I am considering the Sony 900 series as well. The LG 86" uses a 120 hz panel. The 60 hz panel is only in the smaller sizes of that series. Some others have also suggested the Samsung Q8 82" TV for exceptional picture quality or even the 82" NU8000.

    86" LG or 85" Sony 850 series?

    Shopping for something in the 80"+ size. The only place with these TVs on display is a local Best Buy. They also have the 82" Samsung. I am upgrading from an older Sharp 75" 1080p set. Anyway, based on size and reviews I was thinking the LG 86" for around $2500 but the home theater expert at...
