Also DIY can be more expensive than branded speakers as you will have to invest in many tools - LCR meter, measurement microphones, learning time, simulation software, measuring software etc. Also if its a first time experience then seldom first attempts are good sounding and you will need to go through the learning curve. Unless you are passionate about building speakers for own use and others, i will suggest it does not make sense for trying the DIY route and go for a good branded speaker at your budget. But again if you enjoy doing DIY and are ready to invest in time and money then its a good hobby to pursue.
