I know someone who's looking for a great sub for a great price, so I have similar questions. You simply stated that you had three to get rid of for $150 plus shipping, Is that $150 a unit? If you're building these up before sending them out what size are you looking at doing?

Thanx dude. Thank you, I really appreciate that. When I get a plan or idea I try very hard to ensure it's going to work and stick to it. So far, so good. Well, after a couple of weeks of listening to the Bravox's with the added power all I have to say is that I'm more than very happy. The components in the Van are very sterile and precise, I'd love to hear what Chop remembers of them too. They play very clean with no hint of distortion, however they also sound a bit dry or cold. They sound excellent but they lack some midbass (not their fault, its the install) and can make some music that gets real busy and excited sound a little less so almost as though they suppress the recorded distortion or it simply doesn't come across. Such as the song Land of Confusion by Disturbed which has some great guitars that are recorded with some distortion. You hear it, but sterile is the only word that comes to mind to describe how you hear it. The Bravox's are just as precise in playback, albeit with a hint of beaming that I have mostly EQ'd out, but sound SO much warmer, fuller, and with a good deal more midbass. Their detail and warmth are what impresses me most, almost like listening to a really good set of house speakers on a big old school amp like a 1970's era Marantz receiver. I find myself looking for any excuse to take the Jimmy places and find myself sitting there and finishing the song I'm listening to every time I reach my destination. They sound full and alive and I sure as hell wish they still sold their product here in the US as I wouldn't hesitate to buy more. It also makes me antsy to play with the carbon fiber 3 ways I picked up awhile back. Final design of the enclosure has been verified and the construction has begun, although to implement one aspect of the build on it I need a good table saw. Since I don't own one I'm going to go talk to an old family friend and neighbor and see if he still has his wood shop. If so I'll use his to make the cuts I need. Otherwise this thing should be coming together real soon.

In the chat..... for anyone who's interested....

to the forum! The amount of knowledge available here is amazing. You'll have no problem getting the answers to any of your questions!

to the forum!! You've definitely come to the right place if you want to learn, especially if you want to learn the right stuff and the right way of doing things. There's an incredible amount of knowledge amassed here.

I can't help it, but I hate seeing people refer to the Re of a driver as though it counts as the IMPEDANCE load the amp is going to see. Going to end my rant there. Now back to the regularly scheduled programming.

LOL

Would be AWESOME if you stopped by on ur way up or back home. Would grill some burgers, steaks or whatever you like, have dinner, demo and hang out for a few. That invitation is open to anyone else traveling up too BTW!!!

Maybe... but modeling alone will NEVER tell you what's its going to do in the real world. Very few programs can model for a given room size, fewer (if any) still can model for the interior of a vehicle. How the modeling software states it's going to perform in an open space is completely different from how it's going to act in the environment you're planning on using it in. Reflections, resonances, and other environmental variables can only be tested for from my limited experience. If a manufacturer has done real world testing and discovered a range that they find offers the best overall performance in a multitude of environments then that should be enough for anyone who's not capable of determining what type, alignment, tuning etc. would be necessary to attain the goals they've intended to use a particular driver to fulfill. Hence the purpose behind building, testing, rebuilding and retesting until a person either reaches the goals they were trying for or can live the compromises the encounter. The majority of people are not perfectionists and often live with whatever results they get from a first try and there's nothing wrong with that. Hell, on most occasions I do so myself unless its a complete miss. Then I don't hesitate to recheck, rebuild and retest it until I do get what I want.

I'm a couple hours from Indy, but you'd be more than welcome at my place brother!

My memory does little to serve me at the moment, too early in the morning for my gears to be turning yet, so I can't remember how they're configured in your truck. The thing is, I know a guy from up near Chicago who has done several big setups in the Trailblazer he used to own and a Cherokee he's been using for builds as of late. He for a long time had an issue with loading inside the enclosure that would always destroy one sub. When he had the TB he had four 12" DD 9512's in a box below the window line and in a wall, and I can't recall exactly what the issue was but it caused a problem with those subs. When the TB got totaled in a traffic accident he got the Cherokee and built a huge wall for four SA-15's. The one in the top left corner would always blow, the spiders would shred and the VC came unwound on a few occasions. This issue was found to be a leak in the rear wall of the enclosure. Not sure if any of the above could apply to your situation, but it sure sounds familiar to me. Could be worth checking out.

to the forum!! This is definitely the place to be if you want to learn more!

3/4" is plenty for any typical daily use build. Sure, if a person was doing four 18's that weighed 90lbs a piece and 20,000 watts of amplifiers powering them then yeah 3/4" isn't going to cut it. A pair of 12's, 15's, etc. with respectable amounts of power, etc. will be just fine on 3/4" MDF or even marine grade plywood. It all depends on what a person's doing and their budget. I agree, two Q's should be plenty loud enough for you. Mine are loud enough that they even have my wife turning them down on occasion which never happened before. She didn't know what too loud was until this build. I had to laugh pretty hard once after she came back from a run to town listening to some new song she got to listen to and said she had to turn it down because it was vibrating her eyelashes into her eyes making it impossible to drive. They're not as loud as many other subs and setups out there, but they're plenty enough for me. The best part is while they're getting loud like that they're still playing every note with the most authority and clarity that I've heard to date. Albeit a limited sampling compared to most of the guys into the hobby and on this forum. I completely understand about taking time to get a build done. It took me well over a year to complete the van and I just got the amps in my Jimmy weekend before the last after purchasing them two years ago. It took almost two years to complete the doors on it and get the wiring ran for the amps. So believe me, I know all about taking time, but it's worth it in the end. There's also NOTHING wrong with figuring out exactly what direction you want to go and figure out exactly what your goals really are before starting on it. I for one would much rather it take way longer than I want it to but have it come out exactly like I want rather than to do it as quick as possible and then have to do it over again. EDIT: I need to make it clear too that when I said I wish I had double baffled the box for the van, it wasn't for the added strength as it is a very solid enclosure, it was so that the subs would have been flushed in. It would look a fair bit cleaner that way is all.

^^^^ Exactly. I should have double baffled the enclosure, but I didn't want to cuz I hate seeing the enclosures with a 3/4" thick outer port wall, 3/4" thick bottom port wall and the top of the port at 1.5" The window style bracing is a nice way to brace the enclosure and can look pretty kewl when the windows in the bracing are special cutouts. The idea I had for my SA-8's enclosure I was going to use in my Jimmy before I changed out for the XCON was to put the double baffle inside the enclosure to alleviate the one thick port wall look. Never built that enclosure tho so I have no pics to explain what I'm talking about. EDIT: You ninja'd a post in there, lol. The ^^^ and exactly were for your post on the plexi thickness and double baffle info.

Pretty much exactly what you're thinking is how I did it. I cut out a frame that was 1.5" larger than the 12x24 window. Used my router to recess a 3/8" wide and deep lip into the frame and the plexi itself. Then sealed the hell out of it with silicone and glued it to the front panel of the enclosure. The window on the front panel of the enclosure is an inch smaller than the window for a good sealing overlap. It's been a successful way of doing it so far. I was going for and like the look of the deep recess to the plexi window. The plexi sandwiched perfectly between the frame and the enclosure front and hasn't had any sealing problems yet and hopefully never will.

I didn't correlate the calculation of the port area to enclosure size, that's not what I meant by that statement. We both know the so called "rule of thumb" if calculating XX.xx sqin of port area per cuft of enclosure size is not the right way to calculate port area. As you know, the more port area you have the longer the port has to be to maintain the same tuning. That causes the port to rob more displacement inside the enclosure causing the enclosure to have to be larger to maintain the correct NET volume. That's what I meant about the size and not going any larger. I used the maximum dimensions I was willing to give up and that was the maximum amount of port area I could utilize and still maintain my preferred 4.2cuft of net volume, 32hz tuning and stay within my limits. I do agree, using less than the ideal port area can and does still yield very usable results, and thanx on the enclosure, tho it's Chevy Orange, not red. lol

Actually I wish I could have made the port larger. Only reason I didn't was because of space. The enclosure is 4.2cuft NET tuned to 32hz and is 17" square by 42" long. Making it any larger was really just out of the question. I'm sure that if it were me I wouldn't be using a single 6" aero, it's just not enough port area alone. A pair of them would probably suffice though ideally it should be more.

Thanx. It's tuned to 32hz and sounds absolutely amazing. Best subs I've owned so far, tho I've yet to get to use my XCON so that may or may not change soon. We'll just have to see.

Easiest way to do it is to create a free account at photobucket.com, upload the pictures there, then copy the "IMG Code" link and post it in the thread. I have a pair of the old series Q's, I think the change happened in 2010, not 2011. If yours has the double slugs, it's the older model like mine. If it's the single slug motor then you've already got the new model. Here's what the motor looks like on my Q's. Here's my enclosure with a plexi window too, just for reference. Got the plexi from Delviesplastics.com, 3/4" thick. Works out really well for working it into the MDF since it's the same thickness. Hope that helps.

BUMP C'mon guys... I figured this would have sold fast. It's a great amp for a great price. If I had any use for it I would have bought it from him myself. BUMP

BUMP As stated above, this is a NICE sub here. Never been used, never been mounted, never even seen power from a battery to do a polarity test. NEVER BEEN USED! This sub is also considerably more expensive new with all the options like this one has. BUMP

to the forum Bob! If you've come looking for knowledge there's not a better repository of information available on the internet nor a better bunch of guys to help explain it all.

^^^ I agree. That's a VERY respectable job for your first enclosure! I've seen MUCH MUCH worse from kids around here on their first enclosures. Hell, my first enclosures were a joke. I still have them, I'll get a pic and post it someday. Of course I was 13yo when I built my first ones so at least I have a little excuse, lol. Honestly, that's not bad at all for a first time attempt at building an enclosure. I'm sure you learned a bit from it and the next one will be even better. Congrats!!
