I agree with making the port longer. This will work. If you make the port longer this will raise the F3 of the speaker and lower the F10. It will make the speaker sound leaner but deeper in your room. This is because by making the port longer you have effectively lowered the tuning frequency of the cabinet. This is one of the beauties of DIY. It is possible to tune the speaker to the room. All rooms are a little different. I have wood floors (little absorption). I generally pad my tweeters about 2db to compensate. It works pretty slick.For experimentation without damage to your speaker you should use a straight pipe (cardboard?) and merely extend the length of the port from the rear of the cabient. Use masking tape and attach another 2" of port via masking tape. If you get finiky I suppose you could use some poster putty to smooth and seal the transition from the factory port to the extended one.
If the added length does work then make modifications to the inside of the speaker.
Longer ports sound leaner. Shorter ports yield more boom. Many small speakers have ports that are too short. This creates a slight hump in the response at 50-60 hz and a very marketable bass signature.
Good luck in your quest. I believe your speaker is fixable.
