B2 Hertz Posted April 8, 2015 Report Share Posted April 8, 2015 I'd build a new box, maybe a 4th order or 6th order depending on how much space you have. If you are still not satisfied with the output of your system then I'd look into a different setup. New box will be the cheapest and quickest thing you can do.

YukonDCXL Posted April 8, 2015 Author Report Share Posted April 8, 2015 Sorry Will I did not receive it but probably my emails program fault. Joex wanted me to even go bigger if I had the space which I did not really understand. Would you still go 11 cubes even tho I am pushing over rated power?

will77530 Posted April 8, 2015 Report Share Posted April 8, 2015 yes whenever you are over powering you need to start shrinking enclosure size to help control the subs back pressure and keep the driver within its mechanical limits, if someone wanted you to go bigger the recommended especially with dc subs i would not trust them to design an enclosure for me Link to comment Share on other sites More sharing options...
YukonDCXL Posted April 8, 2015 Author Report Share Posted April 8, 2015 Thanks a lot. Could this be why my subs vc's heat up? I have tuned with dd1 and use clean music but once in a while they still do it... Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted April 8, 2015 Report Share Posted April 8, 2015 Getting a significant increase in output requires either a big increase in power (like twice as much) or a big increase in efficiency. Doesn't sound like you want to change your power situation. To get a big increase in efficiency you are either going to need to increase your cone area quite a bit and make some big improvements to your box. The problem is if your box is already pretty decently designed, there may not be a ton of room for improvement. Swapping out your current pair of 18"s for a different pair of 18"s is unlikely to do much for you either. If you got the space a big increase in cone area with a well designed box is probably going to be your best bet.

Although I never issued a design for you I apologize for the misunderstanding on my part. I dont know if you have experimented with higher tuning, normally guys wanting to get louder on a given setup go for mid to higher 30s. Link to comment Share on other sites More sharing options...

YukonDCXL Posted April 10, 2015 Author Report Share Posted April 10, 2015 JoeX, your redesign you gave me for my current box is great and I appreciate all the help and time you spent with me. I have decided not to change this box at all and only rebuild if I change subs or add subs. Thanks again Link to comment Share on other sites More sharing options...
