Are your speakers designed for your listening taste and hearing ability?


It occurs to me that speaker manufacturer’s and designers in many cases design their speaker ( and its subsequent sound) to the expected ’typical’ buyer. IME, a lot of high end speakers are designed to appeal to the consumer who has a certain amount of ’hearing loss’ due to age! This might sound odd, but I think that there are a lot of a’philes who have reached a certain age and have now two things going for them..1) A large enough wallet that the expense of the speaker isn’t really the issue and 2) a certain amount of high frequency hearing loss. This circumstance leads to designers and manufacturer’s bringing out speakers that are a) bright, b) inaccurate in their high frequency reproduction and c) not accurate in their reproduction across the frequency spectrum ( some may be tipped up in the highs, as an example). My impression is that a certain technology catches on--like the metal dome ( beryllium or titanium, as an example) and the manufacturer sees a certain public acceptance of this technology from the --shall we say-- less abled in the high frequency hearing dept, and the rest is as they say...history. Your thoughts?

Is "music performed in a real space" always acoustic? And if so, what are the acoustics? Tall feathered hats and corrugated steel walls? Outdoors with actual bird sounds (back when there were birds). Carnegie Hall? What seats? Can you sit under the Steinway? I'm a decades long (and 6' tall) successful musician and frequently over paid live concert sound producer/mixer (as well as a coconut margarita mixer), and I can say with confidence and a slight lisp that there is no bottom line regarding live anything. Or maybe there is. I've recorded an acoustic guitar on state of the art (maybe) recording gear and played it back on my hifi rig while sitting there playing the same thing on the same guitar as a demonstration for a friend or two. My hifi rig replicates the guitar tone very well, thus proving something I already knew that I don't care much about. If a recording sounds great to me, it just does...if it doesn't sound great it doesn't. How do I test that? I don't need to. Except where previously noted.
One big advantage of my DIY speakers is that I am not afraid to keep modifying them until they sound right.  Since I got my fully horn loaded, DEQX DSP'ed speakers to playing in 2004 I have changed woofer drivers, folded corner horn enclosures, midrange (actually wide range) drivers, all amplifiers, added supertweeters and upgraded the DEQX DSP. I have finally got the triamplified three way horns to sounding and measuring as good as I imagined them before I started sawing wood and machining metal.  I am very gratified to say that my audiophile friends all say that they sound very good.
20 years ago I was the ‘tube nut” making full range speakers that had a nasty shout....things change and I learned that a lo powered tube system has to do sound from more than just the parts....they work to bring out the best of it all....room included.....now people are amazed that they hear a really hi-dollar “sound” in 2-3 watts from nice horns well placed—-the ‘live in the room’ music.....from invisible speakers!!!!    2 ways of getting there I guess.......
