Subwoofer DIY recommendations

Hey guys...

I just picked up one of these...

I was thinking about buying the matching flat pack from parts express...

I'm wondering if this combo with a proper amp would work with my Tritons in a large listening space. The Tritons have the built in subs with adjustable gain and I'm not unhappy with them, but would enjoy a bit more heft in the bottom

Hoping for some thoughts on this whole thing, as I'll probably need some amp recommendations as we go along.

Thanks all...
Paul

Havya looked around or posted on PE’s tech forum?

Easier to track down someone there who’s walked that road. I believe that package should pressurize a medium sized room with little trouble. Or post your question on...

... that link. I’ve done the same though I have yet to follow through on the advice as I’m up past my eyeballs in a ginormous backyard improvement project that includes an 33’x18’ above ground pool surrounded by a deck plus another deck between the pool and the house

Any thoughts on my post above? I’m leaning towards that flat pack as I’m a rookie in both DIY and woodworking.

I’m hoping that driver in a sealed enclosure will add enjoyment to my main listening space.

Edit, sorry Tony @gp4jesus , I posted this response before I saw yours.

I read all reviews and questions/answers on both product pages, but I’ll check out the tech forum.

Good luck on the back yard project!!

Looks like a fun project. I think you should start by re-reading all of the Parts Express comments in detail then start searching more on the web. This looks like a popular subwoofer so let others experiment and do the work for you. I briefly looked at the comments and some were saying you need to tune the box with a port and another mentioned another enclosure is better. It sounds like you need to read up on subwoofer builds

But I am sure it will sound great when you are done so keep us posted.

Paul,
Forgive me for essentially reposting and getting long winded. I’m assuming you’re adding to a 2 ch system. Further you did not say what your goals are in connection to your existing setup.

The PE product page for that driver suggests per BassBox pro sealed: 1.58 cu ft, F3 50hz; ported 2.72 cu ft, F3 30hz*. The flat pack w/ the right size port should net you above*. Sealed requires something to reduce the closure volume. WinISD may model w/ different results.

Scour the forums is all I can suggest. If I get time later, I boot up my VERY slow windows note book to plug in your driver’s TS parameters into WinISD and get back to ya. 9:30 is still fairly cool to slave on my Backyard project.

Mind you these modeling softwares are not perfect but they DO give a pretty accurate place to start as opposed to guessing.

@gp4jesus thanks for the reply

My plan is to add them to the 2-channel system in the living room. 18'x30' open to a 12'x12' kitchen. It's a big space.

Current speakers are GoldenEar Triton 2's. https://www.goldenear.com/images/manuals/TritonTwoPlus_Manual.pdf

Basically, I don't have any expectations. I'm fairly happy with the bass from the Tritons, but I have to turn those bass drivers up almost all the way to really feel solid bass. My hope would be to solidify the bass in that system.

I came across the driver for a deal, and I haven't done much DIY, so I thought this might be a good way to start out.

Possibly something like this to drive it?

What kind of music are you listening to that supposedly has all this "bass"?

hochpt21

Lots of yazz flute

gp4jesus

That amp is PACKED with feature ladden DSP! Should easily drive 2 of those.

That Dayton 15 models nearly the same in WinISD. I suggest you port* the flatpack**; the same* available at PE. F3 of 30hz. I’m sorry I don’t recall port diameter but I think the length was ~14”*.
*wait until you find a thread some where
**should you decide that way

I hope you can locate someone that’s traveled the road you’re on w/that driver. I somehow think that driver is capable of a lower F3 w/out the aid of a lot of DSP though regardless it’s should pump.

Paul,

Here’s a 77 post thread on that driver that suggests greater extension is achievable. I read the first 21 posts

https://www.avsforum.com/threads/first-sub-build-dayton-rss390ho-15-little-help.1509857/#post-24162402

Read very carefully. You will see some potentially confusing discussion about other projects (stupid). That and their threads are harder to follow when people quote other posts.

Thanks for the info! We are just leaving for a trip up north for a few days. I’ll do some more research and post here later.

I get that not much goes to the sub for 2 channel, but I added a sealed SVS in my smaller system and I am happy with the results.

Also, TBH I got a great deal on a driver, and I’m looking to have some fun with it.

I hafta clarify WinISD vs BassBox: you can use the former for free. Google the site download onto a windows platform system.

IIRC sealed & ported modeling closure diffs was .04 & .08 respectively.

I was razzing you a bit, but I am genuinely curious about what genres you listen to primarily.

I know

Pretty wide variety, but I’d say most often classic rock, jazz and blues. Probably in that order. Some indie mixed in.

Floyd, Zeppelin, Miles Davis, Norah Jones, Leonard Cohen, Petty, Uncle Neil Young, Grateful Dead, Coltrane, Bon Iver, Dylan, SRV, Albert King

Clipdat

Nice, what kind of volume levels do you typically listen at?

hochpt21

Medium.

If the family is out then louder.

So like 75-85db?

Yea, I’d say in that range.
