Here is my first build. I am using a 12" Shiva X that I picked up for next to nothing and an Elemental 500 Watt amp that I picked up as a b stock item. The box is 18X18X36 and was inspired by Sonnie's Pulse sub design. I didn't want to spend too much until I learn a little bit off of the first build so I am starting small. I'll post more as the week goes on and post the readings from REW once it's done. Thanks to RoadRoach357 for coming by the house to supervise.:clap:
OK Mike, you were right. It is finished and the results are nothing less than incredible. It completely smokes the Outlaws. With all of the frustration I had earlier, the results sound so good I am ready to start another. I imagine Crack is a lot like this. :hsd:
4.97 cubic feet and the tuning frequency ended up at 19.25Hz. It completely dominates, the other subs must now be replaced with another one of these. Well at least when my wife starts yelling, I won't be able to hear her. Posted via Mobile Device
Here is the finished product. I have already made several notes on how to improve on the next one. My patience did get the better of me as I did not spend a lot of time or effort on the painting of the box, basic black and moved on. I will definitely be replacing the Outlaw Subs and have a pair of these in the near future. This was a very frustrating project for me as I am not the most patient person in the world but, the end result was absolutely incredible and worth it in every way. I never really thought the difference would be so monumental but Roadroach357 and Mike P. were right and the evidence I submit is the big stupid grin still plastered across my face. :bigsmile:
your not quite addicted till you sit in front of the pc till 5am reading different build logs, measuring then remeasuring the space you have at 5am, the deciding on a plan, then seeing another and changing to that, then back to the other then back again and over and over it is horrible if i woulda knew i would been like this after building a very simple 23" cube i woulda done it alot sooner right now im thinking about knocking a window out so i can fit the 36" tht in my room, no other way to get it in hahaha.
Well, now that the in-wall project is done, I was able to start playing with the placement of my subs and here are the results. Not bad but not outstanding either, I am going to be moving them around over the next few days and into the weekend and see what I come up with...... Let the madness begin!!!!
Without the mains I have a sharp and ugly dip around 67.7Hz
With the mains on it balances the dip out but causes a small spike at around 65.2Hz.
Thanks guys, since Sunday was the first day I had to mess with it I spent all day tweaking and was a little discouraged at the end but, going home last night after work and watching Book of Eli changed my perspective. And yes Matt, I am already considering the fall for a good time to step up to an 18". :T
Your response looks great below 80hz. If anything spend some time mucking around with different crossover settings and distance settings in your reciever to try to improve the 80-170hz area. you might be able to make some improvement there. Sometimes crossing to the sub higher can help there, you have to watch for localization issues though.
Thanks Josh, now you have given me a completely new reason to drive myself insane....:dumbcrazy: Actually, I hadn't thought about evening out the higher frequencies because I have had such tunnel vision on the sub 80Hz level. Thanks for the input, I will start working on it this weekend. I am currently crossed-over at 80Hz, any suggestions on a good starting point? 120? 100? Thanks again for the input.:T
Welll obviously you don't want to cross too high but if you have 90-120hz setting try them in that range. Just run a quick sweep at 80, then switch to 100hz or whatever and sweep again, repeat as necessary. Your <80hz should stay about the same. If one of them looks better than the others, there you go. After that you can drive your self nuts with the distance setting. Sweep, change the sub distance by a foot or 2 and sweep again. You should be able to narrow it down to a setting that improves the response in the xover region a bit. Don't go to far past the range that is realistic. IE if your sub is physically 10ft from your listening position don't expect 2ft or 22ft to be right. the best setting should be close to reality, somewhere maybe between 8ft and 13ft if your sub really is 10ft away from the mic.
Have fun. Don't kill yourself. Eventually it's good enough.
