Please help with designing a box for this amp and these woofers ( :

[TLS Guy]

Here's how this started, I was running Optimus LX4 I got from Goodwill for $6, on my computer. They sounded amazing, I decided to to the Black Dahlia mod on them, they sounded even better. Eventually I wanted more so I went to the KRK Rokit 5s with a DragonFly DAC and it was even better.

I liked the KRKs enough I went with some Rokit 8s I found a deal on for my TV and music which is run by a second computer I have. DragonFly 2.5mm to XLR cables out to the KRK which are sitting on either side of a 60" television. I just wanted better lows and studio subs aren't super common and I figured I could build better than the KRK sub for the $500 it cost.

And now here we are, me totally out of my depths on how to make a subwoofer and happy to see just how nerdy things have gotten. Huge strides in speaker designing and DIY which is amazing.

I'm open to any subwoofer, I'm just trying to stay reasonable on the price. I'm fine with a 15" or two 12s if that's better, I would like to get down to 20hz for movies and so on. The only thing I'm set on is using the plate amp, I already have it and like the XLR connections.

Thank you all for the responses, ears wide open, happy to buy any sub that would work well with that amp and build any box that served them well.

See the design I have just posted above.

Okay, I've decided on the HT-18 v3 as it appears to be a great value and will more than meet my needs.

TLSGuy posted a nice design for you with a nice sub driver.
And now you totally ignore him and say you want another car audio subwoofer.....size issues ?

Why did you even ask for help here if you are just going to do your own thing regardless of his expert advice ?
Enjoy your rinky-dink system however it ends up.

Somebody making a suggestion is really nice but it doesn't mean it is going to fit my needs, budget, space. You also have to acknowledge you lose some credibility when I'm asking for help building something for home theater and I choose the HomeTheater-18 AKA HT-18 and you call the subwoofer designed specifically for home theater with HT even in the model name a car audio subwoofer.

Soooo, your wanting T-Rex Bass?! Why stop there. Google on YouTube, you'll find a video. Two 32" subs or was it 33" subs, anyway dude built two of them put 2K watt amps in each with Blue lights in each. Showed a SPL metter reading of 11Hz couldn't hear the 11Hz but his wife's hair sitting in front of the subs was standing on her head! En-Joy!

Unless you know something I don't an 18" sub powered by the 250 watt plate amp I linked isn't going to actually bring the house down. In general my thinking is it's allowing me the most flexibility and I would rather one 18" moving 1/2" than a couple of 10s moving 2" as the 18" is just not going to have to work so hard. I'm also not going to have to go through a ton of effort to get down to 20hz for home theater. The 18" honestly was just a much better value than any other option.

OP certainly won't be the first to drive an el cheapo big ass car woofer with a cheesy litle amp....he will live and learn.
