Assassins have been a reasonably sized boner for quite some time now. Ive owned four 8s for a while and have slowly sold/given/let borrow to others. Mine have been both sealed and ported with fantastic results.
Unfortunately i wanted more, as the low end always left something to be desired for obvious reasons. Ive seen many threads about the 8s in sealed and ported boxes, and thats great and all. But I had yet to see someone try something exotic. Im talking about a complete flat response(or near it) from 20/25 HZ to somwhere around 60HZ.
I am now down to my last surviving 8, which called a 1.3 cube vented enclosure tuned to 35 Hz its home for about a month. It was VERY loud for what it was off 300 watts. It sounded very good doing it as well. For this build, I sacrificed a little bit of that loudness for a flat response and pretty **** good low end for an 8, hell even a ten. Behold:
What is it? Im sure some of you recognize it. Its just a simple transmission line (1/4 wave of the frequency) tuned to around 34 HZ with a catch. It has a compression chamber which is basically an enclosure to bring a little more low end out of the line. What does this mean? Anything in the 20s is now loud and clear and nearly flat just as i wanted from mid twenties to around 60.
There is a catch however, the sub acts as if its almost free air, in which case I havve to be careful with what I play. It hasnt bottomed out yet (With about 300 watts), but I imagine it would if I played anything below lets say around 25HZ. But can it play it? Sure can, the mechanical limits are now preventing it, instead of the enclosure. O yeah, its a little big too (Around 2.7 cubes gross IIRC)
So what have we learned? Well just what has been said for many years. Its all in the enclosure. Almost any descent quality sub can do whatever YOU want it to do. I now have my low end, flat response, a still very loud 8, and the accuracy and punchiness that TLs are famous for. I have also noticed that there is less strain on the amplifier, as my lights hardly dim at all (They didnt dim that much before anyway).
Dont sit there, all the info for a TL can be found on the net so you can design one. You may need a little help, the guys at DIYaudio.com helped me a ton with this project and they can help you too. Also try http://www.t-linespeakers.org/
And now for a couple more pics:
Sorry I dont have more pics....Enjoy.
Edit: Keep in mind my trunk is not even sound deadened yet and tis easily the best setup ive ever had. Once I sound deaden, the SQ will be even better.
