  1. I just got my 12" xcon running and it destroys the lows! it exceeds every single one of my expectations. I can't comment on any of the other drivers you mentioned but I have never heard of a disappointed xcon owner 


  2. Just finished my new install, a 12" xcon in a 2.75ft^3 box tuned to 31hz. This is in the trunk of my 96 Accord. I listen with the seat down so the sub and port are firing into the cabin. All my boxes and setups have taught me that each setup is very different and showcase different songs better than others. The "show off" songs that sound awesome on the previous setup don't usually sound as good when you change things. I get that and accept that, but now I have a new issue.

     

    So after I got my xcon playing I was setting the gains and playing around with different songs and was not super impressed, it was loud but I knew it should be louder. so I popped the trunk to go back and check my settings and make adjustments and as soon as the trunk lid opened it seemed like the spl doubled...it was unreal! Why would that happen and is there anything I can adjust to create that effect without having to have my trunk open when I demo? I have the speaker holes in my rear deck sealed off and am going to unplug those holes and see what happens. Will that help? What are the physics at play here? Each install has taught me something but I am at a loss on what I am learning here...


  3. Love the idea Q. There is not much action close to me so I depend on this forum for any help/info I need. I am finishing my upgrade soon and would like to travel to compete next season but have no idea where to start. I have googled classes and rules but still not confident im interpreting the info correctly. Also, as with anything Im sure there are "unwritten rules" and subtleties that one learns as they go that may be beneficial to some of us as well. 


  4. I haven't experimented enough but 28 to 52hz play loud and clear, there is a steep drop at 53hz and from 53 to 59hz there is not much difference as far as I can tell in output. At 60hz there is another steep drop in spl and it seems there is a gap from 60 to around 120hz where my components start to play nicely. I think 80-120 can be boosted by changing my install but I am trying to keep the doors as stock as I can so I deal with that gap. When I fold my seats down I definitely notice a boost in spl, i have also been trying different box orientations in my trunk...I am finding like most things it all comes down to the install...I can't even count how many times I've heard that, and ALL of my experience proves that statement to be true


  5. HU is an 80prs. I have tested sub with mids and highs off. no rear speakers. I sealed off the holes in the rear deck where the speakers used to be. sub is crossed at 80hz 12db slope. mids lp @ 60 on a 24db slope, hp @ 5k 12db slope I believe. I am in the process of dialing everything in as this is my first attempt at running active...it is taking longer than expected :) I will test with the sub in different orientations tomorrow and with the back seat folded down and see what happens. I am building a box for an xcon right now and want to get this figured out before I change my setup, but like hedz, I think it is an issue with cabin gain/cancellation


  6. Thanks for the tips Alton, I am leaning toward cabin gain/acoustic issues but I will move the sub around and check my response.  I checked my HU settings but not the amp...something could have changed while moving my amps around and what not. and I'm sure the box isn't tuned where I think it is, I imagine it's close, but this was my first ported box build...I will check somethings tonight. Thanks again


  7. I have a 12" GCON in a 2.5ft^3 enclosure tuned to 32hz.  I have been lacking in response toward higher frequencies and was curious to know where the drop was happening, as it is quite a steep slope.  I was playing with a tone generator this evening and from 28 to 50hz sounded amazing but as soon as I hit 53hz I lost significant dbs. There was another significant drop at 60hz. Is this due to my box tuning? Can a ported enclosure be expected to produce these frequencies with significant spl? What can I do to get these frequencies to play? Separate subs dedicated to that range? box position doesn't seem to make a difference. Vehicle is a 96 Honda accord sedan.


  8. Just to be a broken record and repeat and reiterate what has already been said: After blowing my first sub I stumbled upon SMD on youtube and fell victim to the dd-1 scam. I bought one along with a new sub and thought I was home free. 6 weeks later I had fried another sub. How could this happen? I used the dd-1? Youtube told me it was fool proof and would solve all my problems! Then I stumbled on to SSA and after some tough love and good, (although sometimes harsh) advice, I have been enjoying my current setup for almost a year with zero issues. Listen to your ears and nose, they will tell you what you need to know, and they do it in real time too!
