$300 budget for Driver and Amp. Need suggestions!

I am building my first DIY sub and need suggestions on the best combo for a driver and amp <$300. Either can be used, I would prefer a new driver however. I have plenty of room for a big cabinet, and have woodshop experience.

I will be building a sealed cabinet, and would be open to a passive or active sub. Whatever will help out the budget the most!
Oh yea, I am probably 70/30 for Music/HT
Thanks.

What will you use the sub for, strictly music, home theater, or both?

The Dayton RSS390HO-4 $150.80 with free shipping:

And the Bash 300 plate amp, $149.87 with free shipping:

Slightly over your budget, but well worth it for what you get.

Re: $300 budget for Driver and Amp. Need suggestions!

Thanks. How would that compare to getting a Shiva-X and bash 300? Could I get good results driving a shiva with a bash 300?

FYI: I am currently using an HSU STF-2 sub, which I plan to sell. I am looking for a nice upgrade over this.

The RSS390HO would have a 4 db advantage over the Shiva-X from 30 hz on down.

Re: $300 budget for Driver and Amp. Need suggestions!

Ok sounds great, so did you configure those settings with a 5.6 net cubic foot cabinet? I was planning on something maybe 4.7 cu. ft. net or so. Would that be adequate, what would you recommend?

Edit: would a cabinet with these dimensions be good? : 25"w x 30"h x 18"d

Yes. 5.6 net cu.ft would have a Q of .706, 4.7 cu.ft would have a Q of .743, not much difference.

25"w x 30"h x 18"d external measurements would have an internal volume of 6.34 cu.ft., which would be about 6 cu.ft. net. Here is an enclosure calculator to help you figure out the dimensions for the size that you want.

Re: $300 budget for Driver and Amp. Need suggestions!

I used that calculator. I had factored in 700 inches^3 for bracing and around .20ft^3 for the driver. I couldn't find exact measurements. Left me with net cu. ft. of 5.79ft^3.

Anyway, for something around 5ft^3, how much fiberglass insulation would you recommend?

Re: $300 budget for Driver and Amp. Need suggestions!

Hey Mike, I am using WinISD Pro and typed in the Dayton HF 15" Parameters and couldn't get close to what you spec'd. Am I doing something wrong? I followed the input directions from the WinISD Help tutorial.

I got the same Cubic Ft size and Hz and Qtc as you showed, but my SPL isn't close to that.
