QDR towers v. 1.0 *home/dorm audio*

[balls_to_the_wall]

Ok, this is jsut a prototype tower to see how I like it and what kinda output it has. I didn't want to mess up a 60$ sheet of BB ply, so I made it outa cheap stuff. It is a little under 3 cubes tuned to 40hz wiht 16in^2 of port area *rearward firing port, don't know if its a good idea or not but I thought I'd try it*. Heres a bunch of pictures that I took tonight of it. It would have been done tonight but the damn jigsaw crapped out on me.
The plans...

Whats this I spy? A 12" jointer that needs to be wired up??

Old arse router and small set of bits...


Quality Radio... AM only

And with just the sides/top/bottom on


The tweets currently are the cheapo Daytons, the drivers are 7" Dayton Reference (shielded). I Just bought some Morel MDT29's tweets to upgrade to also.

They will be run active for now, possibly passive, depending on if I can swing buying Another rack amp to run full 3 way actives in the dorm.

This is my first time setting up anything active. I wanted to play around before I thought of desigining and making a passive crossover network for these. It took me a little while before I found what I liked. I know it can be fine tuned alot by ears more trained than mine, but I don't know anyone like that around. The tweeter gets a little nasty around the crossover point, it isn't even supposed to crossover that low (Dayton 4.60$ ones). I have them crossed over around 2200hz. I'm hoping my new tweets on order will help that out (Morel MDT29's).

My initial hearing was wow, these have some output.

After getting a little more time in on these tonight I've came to a couple conclusions. The crossover point gets a little nasy, a new tweet able to get lower should fix that. These have some considerable ability to dip down low (~2.8cubes 40hz) and are very detailed and crisp. I really like my Fostex's and I think I already like these even more.

These are going in a dorm room once I get the pair built (this is the prototype model). I have a feeling its going to be a little bit of overkill. With the way they are sounding now I don't believe I am going to be running a substage for awhile.

Overall I am very pleased with how it came out, this is my first project that I've designed/built/came up with myself. It is a very pleasant sounding speaker, tight accurate low end, a decent upper range *will be improving*.
