The project is now finished...
I build my first DIY project... as many, the easiest first project to build is a sub...
I was a long shot, I had to educate myself a bit before doing anything, with the help of some other fellow sound lovers here... that I want to thanks...
The driver picked is a 12" Titanic MKIII (for his specs., his rubber surround, the great reputation of parts express)... in a ported 3.4 ft^3 box made of 1" MDF (3.8 rough, before driver, brace, amp)tuned to a bit less that 21hz.... 20.8 Hz in fact... just to respect the rule of 1 x dia. of the port distance between the end of the port and the opposing inside wall.
The amp used is an Hypex HS 500 bought on an ebay auction that I can't resist.... you know this feeling... "I want it...I want it..!!"
I've put an input cup to be used later as an output cup to add another passive box to the unit.
The result is tremendous.... clearly much better than the Velodyne CHT10 I had on test last fall. After a few tests I add 1" thick of polyester on all box walls, it help to warm the overall sounding.... I also use a plug to plug the port, and it make the use for music much better ... to my taste
As my room is pretty large (17' x 20') and had one completely open side, I'll probably made another one later, but a sealed one, this one would be locate at the other end of the room to evenly fill the room. The setup is already able to fill the room, but to rattle the walls, the driver is too much near his limits to use it that way on long periods.
For those who like to see it, (as I like myself to see others projects) I put some pictures on this link: (just copy the link to your browser)(updated link, thank to Dave)
