While I am new to this forum I agree about time and money... I remember my lumenlab projector project .. I spent hours and hours and may 700.00 on material and mess up's.. Same with speaker designs ... I am 43 years old now and I have been messing with stereo equipment since way back in the mid 80's .. I have built so many designs of speakers that I thought would sound great and they turned out to sound like .. I think the speaker building kits are the way to go as well.. On the other hand if you have the tools and money build away/// Makes sure you allow for those little mess up's..
