Problem covering my walls from floor to ceiling

I'm building bass traps thanks to Ethan Winers "Build A Better Bass Trap" article. I would like to cover the corners from floor to ceiling, but my problem is I cant fit two traps stacked vertically. I'm a few shy of being able to fit 2. Its a small rectangular room 9 X 12 x 8. Any suggestions would be very much appreciated!! Thanks!!

Make them smaller?

Making them smaller wont diminish their ability to absorb the same frequency spectrum as if they were larger? I thought they were "tuned" bass traps. I'm kind of confused now... If I can make them smaller & still absorb the same frequencies that would be awesome!!!

If you are treating the corners you will get much better results by building a SuperChunk filled with fluffy pink attic insulation. This will be cheap and effective to much lower frequencies. Do a search on here and you should be able to find all the info you need.

Here's some ideas:

Fluffy insulation with a low Gas Flow Resistivity is the best performing and also cheapest material for these large traps.

You will also want to treat the first reflection points.

Tuned traps have more to do with the depth (for the most part). I will warn you though that tuned is not always the best way to start out. Have you looked at broad band bass trapping or a mix of them? What is the goal for the room? Size?
this is using both.
GIK or Realtraps?

Its a small rectangle bedroom 10' x 11' x 8'. There are two 3' x 4' windows in the center of two walls. The room also has an entrance door & a small closet door. I was going to make a variety of bass traps according to Ethans "Build A Better Bass Trap" article. My plan was to treat all corners of the room with bass traps & also treat the 1st reflection points along with doing some ceiling treatment. My problem is that I cant stack 2 vertically on the walls, because my ceiling is just shy of 8 ft. I've already spent money on 12 sheets of 1" 703.... If any of you know of a better way to treat the room besides building Ethans traps by all means please let me know what I should do!! I'd really like to find a solution to treat the walls & corners from floor to ceiling. Thank you guys for all of your help!!!

Treat the first reflection points, corners and add a ceiling cloud. After that you may want to add trapping to the back wall. Also experiment with the position in the room.

Ideally you want to test the room using a measurement mic and some software like RoomEQWizard to make sure you are doing the right things.

Here is a simple way to make bass traps. I would use 4 to 6 inches of 703 per panel if you can afford it:

...As for the height problem, you can cut the 703 down to size.

Superchunks are still a good solution for corners BTW.

frame the 703 and do not put wood on the front or back (leave open) and cover with fabric. Make the panels 4" thick and straddle the corner. Also treat the early reflection points. 12 piece though is not going to be enough as what you have is only going to get you 3 panels. You can use the following as a guide for set up.

Thank you for your suggestions guys. Just to confirm with you, building Ethans traps wont be as effective when treating my room?

I got your email. As explained at the beginning of my article:

For rooms smaller than 25 by 15 feet you'll do better with broadband bass traps made from thick rigid fiberglass placed in the room corners. Small rooms have peaks and nulls at all frequencies, so broadband absorption straddling corners is better than the tuned traps shown in this article.
So for a small room like yours you'll do better with normal fiberglass-based absorbers.
