Is this a good subwoofer design?

[anglerz007]

Hello everyone, I am new to this forum and would greatly appreciate any help. I have done a lot of research and learned almost everything I know about audio from just reading through posts on the forums. Based off what I learned, I want to build a subwoofer, which will have:

--Dayton Titanic 15" Driver
--Dayton or BASH 500w plate amp
--250 liter enclosure
--Port tuned to 17.8hz

Is 10 gauge speaker wire sufficient for this project? That is what I had planned on using.

If you have any suggestions or comments, or anything you think I should do to make the design better, please feel free to post. I have a $500 dollar budget, if there's anything I can do to make this design better while remaining within my budget, please let me know.

PS: Will this subwoofer be good for music, movies, and games?

--Thanks

Dayton recommends a 153L enclosure tuned to 23Hz for that sub (I'm assuming you're talking about the current model, Titanic MKIII)

Any reason you want to deviate from that?

His design sims better than the dayton recomendation IMO. Sort of a mild EBS gets that last half 8va of musical material and compensates for room gain. Looks good to me.

Yes I am talking about the MKIII. I didn't think their reccomended enclosure was always good?

Thanks for the responses.

There is a 3db difference at a certain frequency in the 2 designs. I think 3db indicates a doubling of power, but does that also mean a doubling of loudness?

They're recommendation is for a plain ported system.

If you're going for EBS, then I think you're spot on.

I'm gonna feel dumb, but what do you mean by an EBS?

And what will be the differences in my design and their reccomended design?

Is 500 w overkill for this design? In WinISD it looks like 350w will work almost as well.

EBS = Extented bass shelf:

(that should answer both questions)

That's really personal preference. Either should be plenty loud for a HT setup.

I guess my question would be what is going to happen to the speaker at Fs. Qts is close to what it should be but on the high side. The speaker may not react right at the lower end.

Drop a line to PE and ask if they would recommend this alignment. Strange things happen down low.

I don't know exactly what you mean, but I will go ahead and contact Partsexpress to see if they would reccomend this allignment.
