SpeakerCompare tailors your listening experience to the exact headphones you have, so that what you hear is comparable to auditioning speakers side-by-side in person. Two different listening modes. In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power.
In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers. In equal volume mode, we've made the loudness of each speaker about the same.
This gives you a more direct comparison of subtle voicing differences between speakers. Nothing beats listening to speakers in your space. SpeakerCompare gives you a sense of the sonic differences. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material.

Infinity Thread starter synapsis Start date Jan 26, Alright, so a few weeks ago i thought it was about time to make myself a couple DIY subwoofers, as i have a complete home theater system except for a sub! I picked up two. The next day at work, i had to come up with a driver for the box, and it just so happened that my store had demoed a pair of Infinity After all of this, i figured i had hit a sang, as i had no idea well i had SOME idea how to build a custom design subwoofer box that would fit the woofers acoustic properties.
Avaserfi and WmAx gave me a bunch of advice, and now im on my way to design a proper box, modeled after avaserfi's box for his VQ however, mine wont be nearly as complicated, as im making two and am not that articulate in my woodworking. So im planning to build a 3.
The slot port will be the same as well, and im assuming back slot ports are the way to go? And other than some MDF, hardwood for bracing, and the mineral fiber board, is there anything else that needs to be added? Im going to post some pics of what ive got, it'll be a slow build but i can keep everyone up to date. Just want to shout out to WmAx and avaserfi for all the great help!
Last edited: Jan 26, Having never had to worry about a plate amp before, im wondering how to design the slot port. After looking at avaserfi's box, i realize i can't create my port like this, as it would be "in the port", if mounted on the back. Im wondering if i should make a seperate chamber for the amp at the back of the box, and make the slot port longer along the width axes Should i just mount the plate amp elsewhere on the box? How does velodyne and other slot ports with plate amps on the back design their boxes?
Thanks Dustin. I am building perfect kappa sub as well. I am getting closer to being done, I am having hard time finding the 8 miner board. Here are a couple of pics of my work in progress. I was planning on using a plate amp when I started and switched to the behringer ep, which I got from the brown truck tonight. Now I will have start another project, building or buying new stand for audio equipment and tv stand as it dont look like the rack mount comes off of the ep I still need to borrow router and open up the outside wall for the port, as my router died on the construction.
Looks pretty good. Are you using MDF and particle board together??? If need be, i can drill a hole in the back to give some airflow out, so as not to overheat hell, maybe even put a nice little fan in there that kicks on whenever the amp is on. This way i can still have the staggered slot port like avaserfi. I wish i was good with autocad or something, so i could show everyone what i was looking at doing I started using mdf, then I ran out
