What is the easiest speaker kit, for a Novice?

Your best bet, especially if you don't want to build crossovers is to buy a madisound kit. Parts express has finished enclosures you can buy, but you still need to route the driver holes.

As Mitch2 pointed out, Mensicus audio will design speakers for you. They can actually provide you with a completed speaker. Enclosure finished and everything. You can choose one of their kits or have them design something custom for you. They are more than happy to build the crossovers as well.

Are you looking at DIY to save money or because you have interest in it? You won't be saving any money having someone build the crossover, and cabinet for you.

Let me explain, I have had 30 pairs of high end speakers. Now I would like to see the internal working of the speaker in as simple a way as possible. I want to save money because if I make a mistake it won't have that much of an impact.

You might look at the Audio Note Kits. I've not heard the speaker, but I built the dac 2.0 signature kit and, to me, it is fabulous and bettered my modified Wadia 301 by a large margin. The speaker kit does not look too complex and you can order the cabinet too - and I found Brian to be patient and helpful. Jeff
