Building new DIY speakers

As you can probably tell, they didn't have their reflex tubes put in, we forgot those at his workshop. Oh well. Anyway we will get those and put them in on saturday. As for listening impressions, WOW. They are loud and they are deep. Once I get them back home in America and in a proper room, put them on gramma pads, get a proper 4 ohm amp with room optimization and equalization etc etc I am sure the sound will tighten up and be even better. These things could play at ear splitting levels with no hiccups. In the room overhead the guy came downstairs to where we were and told us his remote control was walking across his coffee table.

I tested them out with a bunch of different music I like. Youtube it if you want.
Cynic - The Space for This
Fleshgod Apocalypse - The Violation
Born of Osiris - Recreate
Dev - Bass Down Low
The Human Abstract - Faust
Hester Prynne - Leeann Legore

In the last picture you can see 2 smaller towers behind the monster ones we build, those are some he designed and built, with, I think, 12" side firing woofers, in a sealed contruction, and you could immediately tell a difference when we compared. The ones we built for me had a much fuller and complete sound with tighter bass, even without the bass reflex tubes even in. His played loud for sure but they started to hurt your ears at higher volumes whereas mine didn't at all, even in that sub-optimal room with all hard surfaces.

I love it when a plan comes together! Sounds like you'll be quite pleased when the tubes are finally installed, because most ported speakers sound like a** without their tubes.

Have you settled on an amp yet? I had picked up a new Crown XLS amp at less than half price when they phased out their old A/B line a couple years back and everybody was liquidating stock. The fan does make noise, but we have not found it to be intolerable from within the AV cabinet so I have not bothered modding it.

Some of the price difference in the pro amps is in their ability to be abused and pushed to the limits when providing sound for a variety of venues. Sophisticated anti-clipping technology, overbuilt output stages, robustness to survive the constant handling and van rides from show to show, etc. When you buy one for home use, you're sizing it to work at a fraction of the power it's built to produce, so you're negating most of the factors that differentiate them for sound reinforcement work.

Check out Musician's Friend. They have a great return policy, free shipping, and a selection of used merchandise. I got my eq from them for a song - it had a slightly bent corner on the front faceplate, but works great. A pair of pliers brought the corner back. ;)

The towers are complete, We built a custom designed center that is 2.5 way with the same MTM drivers in the towers, but in a sealed cabinet of about 17 liters of volume, versus 5 liters in the towers. We also built these Visaton - Lautsprecher und Zubehör, Loudspeakers and Accessories for the surrounds, they are a little better than bookshelves :).
Then for the coup-de-grace, we are custom designing a subwoofer utilizing this little guy: MONACOR INTERNATIONAL : Product Detail Page

Since I am flying home on the 12th, we don't have time to build it and send it, so we are just sending the sub and the amp for it(haven't decided on an amp yet), and I will build the box with my dad. Then I will rattle all the windows in his house from the basement when I test it.

I am going to listen to the 5.0 system (with one of his subs) tomorrow with star wars and some other movies as some demo material. I will take pictures and post them tomorrow or thursday as well as give listening impressions.

I AM EXCITED!
