Ehhh? Wot?
Audio was a passion of mine back in the 60's and 70's. And today my hearing is horribly compromised. High wattage is needed for Hz 250 and lower. Most YOUNG audiophiles have systems that sound terrible - like a 40-year old Wurlitzer jukebox.
Partsexpress.com is a good place for speakers. They have MIDrange exponential horns that issue bright and crisp mid notes and voice that the most expensive cone speaker cannot even begin to touch. Hearing impaired need a top quality 10 channel equalizer pre amp. Beyond 5K is where good power and ribbon tweeters can be useful.
Two thousand watts would be enough for me to enjoy Beethoven's Moonlight Sonata three-blocks distant. My hearing loss is frequency selective so my in-the-works mini system concentratres on filling in the gaps.
Two thousand watts is power enough to rattle a sub-woofer to the point of fatiguing spot welds in a car body. I designed alternators for a company by the name of Northwest Regulator almost 30-years ago. Most modified designs sent the power curve way the hell and gone upward as far as rotor RPM is concerned. A 200-amp alternator that charges a max of 50-amps in suburban traffic is worse than useless. This is where the ND hairpin alternator would shine.
My $300.00 system now in Las Penas blew away a friend's $4, 000 home system. Not for db noise ouput - for quality of sound. Saxaphones, flutes and violins sound realistic
Muffled wall shaking whuumph bass does little for me. Listen to a bass fiddle or bass guitar live then compare it to the distorted concussion of some "high end" car systems.
Enough preaching...
Good fortune on your project. My earlier sarcasm was directed at the younger crowd. The ones that enjoy rattling your windows 3 blocks away as they drive.
