i have a kenwood kec202 3 way crossover doing my job its got a band pass filter in it with a high pass from 0-1khz and low pass from 1-7.5khz i think
Not really.
It simply won't be able to produce clear highs, or deep lows.
As the name suggests "mid-bass" It is designed to work best at certain mid bass frequencies. Hence it really should be band passed. The manufacturer should give an indication of at what frequencies this should occur.
If your amp has both a high pass and low pass x-over on the same output than the answer is YES.

my amps has full range, high pass and low pass function. is that the amp built in crossover you are talking about?

You want to be able to apply the high pass and low pass at the same time. If it can do that then you are in business.
You need to stop high freqs and low freqs going to the driver.

Okay.
1) yes, the midbass driver can play full range. you'll get early distortion (sub-bass). You'll get crap high-range sound, but it will work.
2) Yes, using the amp filters is a great idea, if they are available.
3) Note, DONT try this with any speaker...tweeters, for instance, will probably blow up, if you try to run them full range.

for a midbass driver somewhere in the region between 40hz to300hz is a very good idea. however some mids are not very good at producing below 700hz like the 3inch domes you see in 3way sets. Then you have to adjust the midbass to suit the driver. For a midbass to be used with a 5 1/4inch mid then you can use 150hz to 300hz x-over depending on mid and x-over slope.
if you have a dedicated midbass it sounds best when you setup a x-over for bandpass. Active setup via head unit or a combination of headunit and amp x-over (just remember that its rare to have bandpass x-over on an amp).

i can relate to tweeters blowing in full range, what a bad accident that was....
so on the other hand, can dynaudio mw160 mid bass play good without any crossover?
No no no, its not dependant on the brand, but the style of driver. The world's best midbass will still sound crap if run full range. Its not a full range speaker. Hence the name.
If you want a full range speaker use a dual cone!!. But even then they should have a highpass xover on them. IMO

Use the below drivers if u want to play full range
Hybrid Audio Legatia 3
or
Jordan Full range
Actually get Jordan JX92S. Can play almost the whole nine octave.

mw160 needs to have a bandpass x-over to sound their best. 50hz-200hz 12db/oct or higher is what id look to do for a dedicated midbass
