You will find a very basic motto or life theme here that keeps recurring:Random efforts produce random results!In relation to audio, this means that buying somebody elses best of everything does not lead to a personal superior result.
Basically processes replace randomness. I am not sure that the direction of building car hifi for eargasms is a noble direction. If I think about music in my life (I am a professional trumpeter), the live experience needs emotional tension and relief - programs that only have popular film music, are spectacular - but only for a while.
Coming from car stereo, the first "problem" that you will have will be bass. Car audio puts our ears in the speaker cabinet - the most unnatural place to be.
I am convinced that the path to a great horn system is a building process over years. As we learn about what horns do and don't do, we develop needs to leverage in our system. I might be so bold as to recommend starting like many readers here with a 12" or 15" in a large sealed box and using a horn from 700Hz (just as an example - depending on the horn, 500 or 1000Hz may be better). Get those to sound properly and then think about implementing a second horn from 100 to 1000 or so as a SECOND step. This fundamentals horn from 100 to 1K is probably the most critical in the system. Spend another year with that and learn about tone and that you can be perfectly happy with speakers without considerable extension at the bottom or top. Once you are perfectly happy, you can search for a LF and HF solution that integrates with the sound of the rest of the system. Go to as many live concerts - especially with non amplified instruments and learn about bass, imaging (I call it geometry and space not imaging) and "air" - all things dramatically distorted in cars or most home systems. Determine what music is good for references - for the fundamental channel, I use for instance a recording "The Schöne Müllerin" with Dietrich Fischer-Dieskau. The voice and piano are very naturally recorded and would show any warts in the fundamental channel.
Good luck. This site is Romys personal diary how he built his system. It is much more than a blueprint for what to buy and how to solder it together. The playback section is a good reference.
