Single fullrange speakers suffer from bad distortion in the highs because the cones are not high quality enough to do high frequencies. You would never use a 4 inch dome as a tweeter in a 2 way speaker would you? Most tweeters are one inch. They need to be small and light to work well. Secondly small fullrange speakers cant do bass. Not just 50hz but even 150hz.
What you need is at least two drivers. Each handles one half of the frequency range. A crossover device is then used to split the signal in half.
Speaker design is not rocket science.
