Just curious if there is anything out there in DIY land that will dig deep (10-15Hz), cost effective, and comes in kit form for somebody without any wood working tools (pre-cut/built cabinet)?

Something much less expensive than the Danley DTS-10, I know that's a killer kit but looking for a less expensive solution if it's out there .

Already have 4 powered subs in my HT (2 are used for mid-bass) and have 25Hz+ covered, need something to fill in the LOW end so it could even be tuned/ported low with less performance above 30Hz.

Thank You,
Jason

only thing I can think of that'll dig that deep at a reasonable price. You could try to hobble together a sonotube and some other driver, but the price of the driver and amp and getting the end caps done will likely push you up to the same area dollar wise.

I have TC-2000 15" drivers in boxes unused that would work for 13Hz performance. You just need a HUGE ported box and the EP2500 amp.

Nothing will be cheaper.

The sonotube option would be a good easy thing to do. Buy the driver and amp of your choice then have home depot or lowes cut some square wood for end caps. You would still need to cut out holes for the port and driver but you can do that with a jigsaw. Cut the cost down to half of the dts10. Wouldn't have the impact as the Danley but would still get good performance and very little to build.

Where do you live? If you're close to the DC area I'll give you a hand.

Thats what i did but you have to watch the cuts, they can some times get them a little off. Still its a pretty easy solution IMO.

I went there with a small mini van and everything stacked up nice in the back once the 2 sheets of 4'X8' sheets were cut down into a nice DIY kit i took home and just put together.

I did need some basic tools but i already had, jigsaw, drill, caulking gun, hammer.

I used trim nails to hold everything together while the liquid nails dried but you could use screws.

I cut the speaker holes and ports with the jigsaw. I used a small 2" belt sander from a friend to round the corners but that isnt a must. I hid mine down under my screen. My 120" screen sits 12" from the back wall so i made mine 36" tallX22" wide and 10" deep. I made 2 for a pair of 12" daytons. I then used a cheap black sheet from walmart and attached it to the bottom rod on my pull down screen and it drapes down over everything.

Mine arnt tuned really low 23hz is as low as i went but thats just what i chose. I tuned one to 23 and then other to 30 i think i forgot. $300. for the speakers, $100. for wood, nails and glue/glue gun

edit: 23hz and 40hz is what i have them at now.

hoffman's law for 1. 2, every time you 1/2 an octave you need to move 4X the air.
Single digits is very hard to obtain at all, not obtainable without money and know how.

What about an infinite baffle set-up? Many are documented to cover that frequency and the drivers are not that high dollar. Plus building a simple manifold is the easiest DIY build one could hope for.

single digits, lots of air. Im guessing 4 18" Fi IB3s and 1 or 2 EP2500's/EP4000's would be a stretch to get single digits... I don't know what you consider cheap.

The OP didn't want single digits. He was talking 10-15Hz.

Exactly. And that can be had with two Fi 18's and one EP2500 (~$800). Depending on the room of course.

I have an empty sonotube that was built for the tc-2000 that Penngray has and if you could pick it up it's yours. It is tuned to 14.5hz with the tc. I live in central Mass.
