Well, it's finally time! I'll be building 3 x 1899's for front left, center and right channels for my home theater. I will also be running 4 x Pure 10's for surrounds. All speakers will be driven with a Hypex amp (build in my signature). Each channel of the amp will do 300-400 watts @ 4 ohms, although, I doubt any of these DIYSG speakers will ever see that much.
My future home theater room is still in construction...it will be 20'x12'x8' when completed. A sealed baffle wall will be built at the front of the room. The wall will hold all 3 1899's, as well as 8 x HT18 subwoofer drivers. There will also be 4-8 sealed HT18's in the back of the room. I don't know if I should call it an IB or a large sealed setup, but it will be very similar to what MKTheater is currently running. I still own and currently use a lil wrecker horn subwoofer (which is amazing). The plan was to build 3 more lil wreckers for the future room, but I feel like I'm missing out on the <15Hz stuff, so that's what pushed me to try this IB/large sealed setup.
The 1899's will sit flush on the baffle wall. The plan is to build the speaker enclosures as designed (or close to anyway), install a cleat edge on the speakers near the front baffle, then mount/seal them onto the baffle wall. I plan to "toe" in the left/right sides of the baffle wall, so that the left and right 1899 speakers are aimed directly at the mlp. A 130'-140' AT screen will sit in front of the baffle wall, and "cover up" all drivers. I realize placing the 1899's in a baffle wall will have an effect on their frequency response. I source all content through JRiver/HTPC, so I have plenty of tools and eq filtering available to use if anything needs to be tweaked or ironed out.
I am fully aware of how much overkill, extra headroom, and craziness this 1899 + 12-16 HT18 setup will be in my small room. I'm single, own my home, and have the time/resources to go crazy at this stage in my life, so please, no haters. Only positive energy allowed here!
So far, I've received the CNC front baffles, the 18" woofer drivers, 12" mid ranges and most of the crossover parts. Erich will get me the CD's, waveguides and remaining crossover parts soon.
I hope to have these built and finished by December, but depending on how weekends go and when Erich can get me the remaining parts, it may be closer to Christmas. Once they're done, I'll do my best to provide unbiased impressions. Anyone in the DFW area is welcome to come over and have a listen. Another local AVS member and I might try to get an assortment of DIYSG speakers (1899, 1099, Pure 10, Volt 10) into the same room at one time and do some live comparisons.
Picture of the front baffles...if you look really close, there's a Pure 10 enclosure on the bottom right
