what are the options out there for sealed full range bookshelf speaker designs?

are there plans out there for shallow, full range, sealed bookshelf speakers?

or am I hoping for something that is currently unobtanium?

I'm looking for something to hang on the walls of my small bedroom. I'm not sure what this room was before the reno that closed in the carport and added many more rooms to the basement, but was 9' wide and 11' long before the added a 3' x 6' closed closet in one corner, so I have next to no room for anything beyond mt twin bed, dresser and chair to sit n listen to my headphones in. listening to then would be when lying down reading n winding down for the day.

also some back story on me to help you understand why I will likely be infuriating at some point while being totally unintentional.

I'm not sure how weird this is, but due to injuries survived almost 25 years ago my brain no longer works like most. I share this as I need to start at the very end and work myself back to the beginning to learn something. this can be frustrating for many helping me as it essentially means I need to be told exactly what I need for a solution and then experience the rule's / law's that need to be understood and worked with to be successful. it's frustrating for me because thus inevitably makes learning something take longer than usual. it's also a pain in the *** because I'm financially of smaller means. not destitute, no debt, but still living check to check.

yes, it does mean that project will be more expensive than it needs to be, but that is the curse I live with after crashing my mountain bike while bombing down a hill and crashing at 45mph. I remember nothing of it, only what I must cope with and overcome since I regained consciousness 2 weeks later.

lastly I'm clumsy n have hands full if thumbs...but fortunately have a patient son in law who is clumsy, but very capable hands that take joy working with wood.

oh, I'm 43, smart yet stupid, live in Canuckistan and pleased to meet you all! 😀

How about a pair of slim speakers, with a single driver 4'' to 6" that covers 200Hz and up, that hang on the wall.
Then a separate woofer that goes under your furniture, etc. It won't be directional.

Can you post a diagram of your room?
 
It is not clear what space you have, but i suspect that the space between 2 studs, and full height is a pretty good volume (about 75-80 litres) for teh SEAS FA22 (they do get better with phase plugs. You may need to add a baffle to the wall to get enuff depth and something solid to attach the driver to.

Not many other FRs that do well sealed.

I have thought about the Elac Debut OW4.2, but there is literally nothing about them other than some discussion about using them for home theatre, which does me no good.
 
All things considered, why bother with a box at all? Just mount IB spec drivers [FWIW I normally used mobile audio or big console replacement 'FR' drivers] to the wall where best suited and EQ to 'taste' and if you want more LF < ~80 Hz, then add a small HT self powered sub with XO.

If you feel the need for a box for whatever reason, then make an open back one out of decent quality corrugated cardboard like is [or at least use to be] used for large appliances, unassembled [motorized] bikes, etc., like me and many others did way back when for kid's, dorm rooms, tiny apts., etc..

with how my bed will be placed, facing the other long wall, I'd have the width of about 4 maybe 5 studs.

my bed would be a couple feet from the side of my bed and 4ft width of it parallel to the length of the bed.

if you imagine a 9ft wide by 11 deep / long room where the south end had a window...look down the room with the window at your back and on the far right corner of the other you see your bedroom door. looking to the immediate left you will see the closet they added that cuts into the room by 3ft depth and 4ft width, making the room essentially 9ft wide by 8ft deep. that leaves a slice of open space 3ft x 2ft between the closet and door and thats where the dresser lives

the head of my bed is against the left sidewall, so parallel to the closets width and leaving 8ft on the other sidewall to mount the speakers on.

I wonder if anyone will take this challenge and try to sketch this, LoL!

can you show me some examples of what you're recommending?

from all the reading I've done, open back need to be well away from the back / side wall corners and even if using small drivers, require a lot of space, more height than width tho.
 
At the lower right of the post.

I really think that speaker (or one of their others, they have several), will be fine.

there are more on-wall options out there...like the Totem KIN or the Martin Logan 4i, but I'm hesitant because it appears those are designed for HT use and mine is for music and if they are tuned for cinema, prefer to get something that is for music.

I was thinking about the Cambridge Minx 22, which would require a sub. being my space limitations, what's out there for shallow subs? what about skinny subs, are the different than shallow? shallow speakers are wide, not deep while skinny speakers are the exact opposite...they are thin and deep.

These are too big for your application but illustrate a loudspeaker specifically for wall placement (this one is wide enuff to have sloped sides to further sid with blending into the wall [visually & acoustically]).

Cambridge Minx 22
Second time in 15 min (on 2 different forums) where the Minx was mentioned. This one ssounds to be a 1.5way (maybe with a slightly different driver for woofer).

You can certainly diy better.

Small subs should not be an issue. I have an example — you should be able to tuck something like it, and use it to put something on. You’d need sats that reach 150 Hz, lower would be better. It has a 2.1 amplifier (a chip amp based one that Daniel tweaked, sounds decent) with an SDX7eN in a sealed box. One wishes you could still get SDX7. Whare in Canada are you?

I read a comment that stuffing too much polyfil is a bad thing as then it creates a situation where the box starts acting bigger than it really is. can this be tracked / measured well or accurately enough where you could take something like the EJJ Eikona 2 and shrink the enclosure and use polyfil to compensate?

Dayton has a couuple and...I forget who, has two sub kits from them yesterday that are shallow. I've concluded subs are shallow because there was never the possibility to make it skinny.
