Hi,
Years ago I owned Omega Speaker Systems speakers with Tang Band full range drivers that I liked. Today I have a pair of regular 2 way speakers in box enclosures with bass ports. I was thinking of converting these to a full range driver speaker if possible. I thought I could use a 6.5” full range driver to replace the woofer, bypassing the crossover and tweeter. Will this work? Thanks.

If the enclosure volume and port tuning match what your chosen FR drive require, the results might be quite fine. In other words, definitely a maybe.
The question as to enclosure volume remains, and not all FR drivers are necessarily suited to - or give their best performance in - sealed enclosures. If this is the OP’s first foray into single driver speakers, it’d be unfortunate to hobble him/her with a generalization that could be bad advice for a specific model.
Not to be overlooked: if his box is too big, it's easy to make it a bit smaller by partially filling it with anything non-resonant and sealed, like sealed plastic bottles. If you need more volume, you'll just have to stretch the box so it's bigger

Those are the pictures of the speakers. They are about 14” x 11” x 9”. The woofers are 6.5” and I was thinking of using these:
Tang Band W6-2313 6-1/2" Coaxial Full-Range Woofer

14x11x9, assumming 3/4” material is about 14 litres.
That TB is a 2-way.
The FF165wk, Alpair 10.3/10p/12p could all be fitted and the tuning tweaked to work with the driver in that volume.

I went with the 10p. Here’s an internal pic. Looks like foam on the inside. F8C5AC31-C48C-4D61-90E3-78CDD6B39253 | Alon Wolman | Flickr

The ports will almost certainly need adjusting. Can you measure the exact dimensions of the existing ports? For that matter, were the measurements you provided outside dimensions?
In a 14 L cabinet, a 2 inch port, 5 inches long would give an F3 around 55 according to Bassbox.

Pull the foam out (and replace it with something natural like wool or cotton felt, and se eif you can get a better idea of the actual volume and i will calculate a proper vent size for you.

On 1st pass i would suggest a similar vent, but lengthen it to 5.7”. F3 is a meaningless number to the ear/brain, F10 gets near 40 Hz.

Only to those who are trying to fool themselves or others that they are getting good bass when they're not 😉
Matt,
Not me saying that, that would be Floyd Toole, from his extensive real-world research.
F3 is only of interest if you are considering the roll-off as part of an XO.

All kinds of things will come into play, room and boundary gain and missing fundamental. So, it depends.....
