Sub modeling help Winisd

post #1 of 31
Thread Starter 
Ok guys. I was modeling the the Dayton RSS315HF 12 in a ported enclosure with 5.3 cubic feet. tuned to 19hz. what I see is that i cannot apply really any power before passing xmax. I also modeled the same sub in a sealed box of 3 cubic foot and saw the same thing. can you guys take a look and see if my info is correct. Also modeled the rss390hf 15 and am coming up with similar data. with the ports tuned to 18hz in a 8.5 cubic foot box and also sealed in a 4 cubic foot box. are my number wrong. when someone gets some time can they model both the 12 and 15" drivers here for me to see if i am doing something wrong. thanks guys.

You must be, neither of those alignments have excursion issues.

I ran the RSHF12, ported in 5.3 cu. ft, tuned to 19hz. I did not enter this driver myself - I downloaded the wdr file from here. A few of the paremeters deviate from yours a little. In any case, how much power are you modeling with? 400 watts? If you model at 250 watts (green), excursion doesn't become an issue until about 17 hz. At 400 watts (blue) excursion looks to be problematic at 37 hz. Not worth the extra 2 dB if the driver kicks the can.

i was modeling with 300w for all the 12 and 15 in both sealed and ported. when i model with 100w on the 12" it models within range. If i go to 250w on the 15" ported i am in a safe range but it is showing i will have an issue in the sealed from 15 to 20hz. it just seems a little strange my my number deviations are causing an issue. thoughts on the box sizes. do they need to be changed up?

That's not real power?

what software are you using. the winisd I downloaded did not have any dayton drivers in it. I had to input these. let me know as it may help me out here

just learned a problem with my modeling as i did not have a high pass filter in play. i added 1 at 18hz and the modeling looks much better

also, xmax is not the end of the road where you crash into a wall. that is xmech or xdamage and is quite a bit higher. if you overshoot xmax by a bit, don't worry.

when overshooting around what percent would be safe? would it be 2% or 10%. a ballpark would be great

It's a newer version of WinISD. It doesn't come with the Dayton's either. There is a great thread on hometheatershack with lots of driver files you can download - then just load them into WinISD. I linked to it in my previous post.

Added the filter to the models and they look much better. What else should I be looking for in the winisd graph capability. The only thing at this point I understand to look for is cone excursion and spl graphing. What else here would be important and why. Another note I pulled out my radio shack SLM and with my paradigm ps1000 and watching The Core as it happens to be on right now and at regular volumes to me it is hitting 106db during some good rumbles This is with the gain only half up on the sub. I'm hoping I get more out of my new build. More and cleaner. It may be getting to that db at what I think is regular volumes but it's not tight the bass is slow and mumbled.

Ok I've been modeling up a bunch of different subs for my project and after weeks of this I think I have come to a conclusion. It looks like I'm going to go with the TC epic 12. Has anyone here worked with one. It looks line I'm going ported with a little over 2.5 cubic foot. Let me know what be think of this sub. Quality, sound etc. Nany links to builds Thanks guys

4 of the epics in my living room setup. They perform well and I am pleased with what they can do. The drivers would be more than enough for most rooms. My room is 12 x24 with 8 foot ceilings. However, I am used to a lot more output because my HT has much larger drivers. However, I am impressed with the Epic's performance and would recommend them for anyone who wants a nice subwoofer.

Are you running the 12's. Are yours sealed or ported?
post #25 of 31
Parts Express. Or do you mean used?

They see
To sell used for a good amount. If they go on sale at PE, I would do that. With shipping and hassle, it might be a better deal in the end. Just a thought.

Keep cranking,

Yeah I tend to agree. What size epics are you running.

Ok guys when you get some time can you guys model up and epic 12 and a JL 13w6. I have run my models in. 4.5 cubic foot box tuned to 20hz. High pass filter tuned at 18hz. Have ported with 3 x 3" diameter ports. Issue port length get long do I need to change it up? Don't have a problem doing that. But the real question is the only thing I know to look for is cone excursion and spl. Wondering if I'm going to have issues with air velocity and port noise etc with these models. Would it be a better idea to try and tune lower than 20hz. My issue doing this was port length. I guess I could have some "L's" inside in the port. Let me know what you come up with. Thanks in advance guys. I'm not stuck on the 4.5 cubic foot can go smaller or larger. Thanks in advance guys
