Default Oxymoron of the day???

Where do I find plans for a small sealed sub that can be made for cheap? Which units to use?
I'm searching for a 50L box that gives me something like 30Hz or below.

Ohh, and it must naturally be quite efficient, as I'm sporting less than 50W power.

Have I reached the search for a true oxymoron?

Cheers

Magura

Hmmm: Small, Efficient, Cheap, Sealed, 30Hz or lower. Can I also assume Low Distortion, Low Thermal Compression and Reasonably High SPL?

Well this does go against Hoffman’s Iron Law so expect it to “take a little while longer.”

I’ve been working on this myself! Check out US Patent Application # 20040136560 at http://appft1.uspto.gov/netahtml/PTO/srchnum.html.

Those pretty much fit the describtion, but they are pretty expensive to build.

Half the price would be ok. like 400EUR or so.

Cheers

You are right, it is the peerless XLS12 and the XLS12 slaves, but for two subs this amounts to something like 1000EUR :-(

Skip the slaves and go vented, I know the vents will be BIG but cheaper.

With a 400EUR budget, you should be able to buy a decent driver and a plate amp so that removes high efficiency from your impossible combination of requirements. Many of the plate amps have a built-in EQ that can be adjusted to work well with a small sealed box. The 12" Peerless XLS is good in 50L with some EQ.

Hypex plate amps
Sealed Peerless sub

Edit: the Peerless prices on that German site are quite high compared to US prices. Try to get a local price since they are made in Denmark.
