Hi everyone,
I am a cheap guy, but I still would like pretty good sound. I'm not sure if this would work because I haven't had money to try it. If you had a 2 or 3 way speaker, let's say a 6.5", and detached the tweeters would you be left with a midbass speaker? also, what is the difference between a midbass speaker and a midrange?

Thank you

You would be left with a 6.5" speaker.  Whether it's defined as midbass or midrange or midhighs depends on how you are using it in your system.  For example, a 4" speaker cannot be a midbass because of the limitations of its size...it won't play frequencies low enough to be called midbass.  However, a 6.5" speaker can be used for either midbass or midhighs (both under the 'midrange' category), depending on what frequencies you're sending to it through the crossover.  But of course you would use the larger speaker cone area for low freqs and the smaller cone area for high freqs.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Buy a real midbass cheap from a brand like Dayton or Peerless at https://www.partsexpress.com/ 

6.5" is the smallest driver I'd start classifying as a midbass.

Relating to midbass, should you enclose the midrange? would that increase the bass response or are all midranges just intended for free-air?   posted_image

Almost all car midranges are intended to be free air. Enclosing them in boxes that are too small will _HURT_ the bass response.

Is there any way by looking at the specs to tell if a 6.5 can be put in a small box and not have the bass take a hit?

The loudspeaker cookbook is at home but I believe, if I remember correctly, that you'll want to look for

High Qts, xmax
Low fs, vas

If you really want to know how the response curve would look then input the speaker's T/S parameters into an enclosure modeling program such as WinISD or others. 

Try to keep the resulting qtc of the system below 1, if possible.

The crappy part is that not many speaker manufacturers will list the necessary parameters.

Good memory, kfr01.  :)

One other thing concerning the idea of using an old coax woofer as a mid-bass: many coaxial speaker system have no crossover for the woofer and run it as a full-range.  So while it may be possible to set up a 6.5" coax woofer to operate in the lower midrange area, be sure to use an external crossover and not try to rely on anything built-in.
