The RCA wire to the amp. The way it is run in back then around. Everyone's a critic man, it's no biggie. lol

5) The box is EXTREMELY easy to drive. the way it "looks" to the amplifier is pretty close to an 8-ohm load across the mid-band of the impedance curve after the fS of the drivers, summed in open air. The amp stays cooler, and does not have to work as hard.

Transient perfect would imply very low phase rotation in the drivers operating range. Hard to do unless you use a Linkwitz transform or better yet digital EQ. I have a hunch you realy mean a highly damped alignment such as you would find in a sealed box with a low Q.

Are you saying the drivers mounted in their enclosure have a similar impedence curve to what they would be free air? Fb = Fs in a sealed box?

As you know the impedence peak at resonance is what limits the amplifier output.

Interesting thread but you are being a little secretive :-)

Your new name is WOP Jr. You can't speak like that about EVERYTHING and not get that name, lol.

On the secretive part, he made something that people have shown interest in buying. In the audio world (just like every other market) it's easy to rip off designs and ideas, maybe even easier if someone knows all the products used in a particular final product. I can see why he's not releasing names on brands or anything. Although, just because he isn't releasing that, doesn't mean it's some cheap shit and he's trying to rip everyone off like someone implied. It's also easy to believe, to me at least, that two 8" subs could outperform two 12" subs because the fact that this setup was designed FOR this car.

I don't have a real problem with the secrecy. If he feels he has to do it to protect his intelectual property I'm ok with it. It does get in the way of a good discusion though and promotes the pissing contest that is happening :-)

Frankly if I wanted a sub in my car I wouldn't copy someone elses anyway. But that's me. Others may find it easier to copy.

I kind of like the idea of two 8" drivers for a sub myself. I have no doubt they can be made to sound great without taking up the whole trunk.

Thanks man. That is really the bottom line, and it is easy to rip-off some elses design. And mabye a lesson for me. That's why my biggest goal is to get people ears on it, hearing is believeing!

Besides, If I wanted to rip people off, I would ask them if they mind hold money from an off shore account while I send them a check or something. And my name would be Bambou, and I would be from somewhere else...

uh-oh, cat's out of the bag...huh?

DON'T EVEN GET ME GOING ABOUT ABSOULTE PHASE!!!!! (you know what I mean lol)

But yes. An extremely damped alighment would be correct sometimes nicknamed transient perfect, but you are correct it is not exactly "Q"... though related!

I like the idea too, and wish he would have been around when I was looking for a sub solution that hit cleanly and didn't take up my entire trunk. His set up would have been substantially cheaper than mine was.

LOL , i haven't heard anything of bose in quite a while.... I was pretty young for their hay-day but i remember those awful bose cube speakers... lol.

Blue04Redline or any others looking for subs like this may want to check out something like an IDQ 8 from Image Dynamics. While maybe not THE best 8" sub on the market it is a good price. I really enjoy my IDQ's and am preferential to them although as always some just aren't fans.
