So I am new to this, but I am planning on building a quality pair of speakers powered by an AB amplifier. The material of the cylinder will be thick aluminum. My budget for each driverranges from 20-150$. The only issue is that I don't know how to judge drivers apart from cost. I am trying to achieve the best possible sounds from 5 inches.
Option 1 would be a quality full range speaker
Option 2 would be a smaller 2-way configuration.
The tweeter would be around 1 inch and the woofer would be 3.5 inch.
Option 3 would be a coaxial driver like this one
B&C 4CXN36 4" Professional Coaxial Speaker 70 x 70 8 Ohm

Kind of depends on your design objectives. Personally I'd opt for a quality full range and make a 2.1 set up
Welcome to the forum!
I like the look of the coaxial speaker, but mainly because it is the only one whose specifications you have made available.

In common with other 4" speakers, the bass resonance frequency is high (94Hz) so it would require the addition of a subwoofer for anything other than desktop use.
You would have to determine the internal volume and mode of operation (sealed/vented) of your pipe enclosure in line with the published parameters of the speaker.
Since you say you are new to this, I have to ask if you are familiar with Thiele/Small Parameters.

Ok so I did study that article. Thanks for the help!
As opposed to the coaxial, here I found a full driver
Dayton Audio RS100-4 4" Reference Full-Range Driver 4 Ohm
The frequency response is greater 80-20k
The coaxial is 95-18k and much more expensive
So why go with the coaxial?

A tube with 5" outer diameter means that you must have a speaker driver that can be fitted in the end of it - so nominally a 4" driver. In that size there is no real benefit of using a coaxial, unless the unit will be part of a 3-way speker with separate bass unit.
The benefit of a tweeter comes from it's smaller diameter and therefore wider dispesion of high frequencies above 5khz. The area of the tweeter is off from bass-midrange driver's surface area, which greatly harms bass capabilities in this size range.
A round 5" baffle gives no support for bass, so the poor 4" driver will need 6dB of boost below 1kHz! Do not expect much better sound than a table radio gives... A high quality speaker design is extremely difficult bunch of restraints and compromises in this size! A dsp helps to get sound balance right, but distortion in bass can not be avoided.

I don't know if it is the best ;-) but I like it a lot HX 10 - 4 Ohm | Visaton
I don't know why they don't have written on web site that tweeter is soft dome made of textile which I like 🙂 so I do recommend it. I have been using it for a few yers now and it is still great.

Worth a read - looks like something that can be adapted to your size pipe - unless you have already got the pipe and you can then use this as a cosmetic outer and sleeve with the plastic pipe.
