I definitely have an obsession - I eat drink and sleep headphones now... I even dream about new ideas (that's where I came up with the fractal mesh I use to de-fract sound after reading the scientific papers published by The Journal of the Acoustical Society of America) but... I can say I used the peerless from parts express (its very good as many other people tune the heck out of it to include Kennerton and Aurora Borealis) and tried dozens of others from all ranges of price- it cost me $9K so far to date to get where I am now and two years of dedicated trial and error- many drivers I throw away due to imbalances - the profits are very small and outlay in $$ is too much work but I'm in too deep now to go back- I found what I think is the best available and now its ready for others to try - I couldn't have picked a worse time to do this I think since economy is soo poor BUT I keep my prices cheap so I think I will have many happy people
