Speakers to hang on to for LIFE

Oris 150 horn speakers you can buy now and keep upgrading drivers and such for probley decades,Allways seems to be new full range drivers coming out ,lots of choices ,plus you can upgrade or repair them yourself ,no need to worry about manufacter suport ,If the finish gets dinged up just repaint .I dont think any other speaker system can compare with the sound and value of an oris horn ,plus you get to build them yourself [easy to do].Way better than martin logans or avalons or avantgarde etc .trio

Sunlight Engineering SE308 concentrics 18in drivers with 500hz compresion horn in center of woofer 104db 50lbs of alnico mag driver can be rebuilt but as is should last 50 + years.Can be used in extreme nearfield or use in a large hall they can easly produce massive SPL off little power.Smooth detailed sound,massive dynamic range, image is near real, tone to die for, makes you feel the emotion in music disapear when on even in extreme nearfield and they are huge.Wish I could keep for life was going to say from my cold dead hands but as with all things have to sell........Maybe some lucky soul will pick these up and keep for life I have owned built designed,demoed beta tested so many loudspeakers these are truly something special.As I have looked in this post for years now I see many loudspeakers suggested that could never last a life time you would need replacement drivers,rebuild surrounds, electric parts, cabinets are built of MDF which doesnt age well.Will such be availble in the future for these models?Will it even be worthwill to repair said drivers? With the se308 this isnt a problem just replace cone if damaged if cone cracks or gets holed no big deal for owner to repair cabinets so over built should last more than a lifetime finish is french polish which will look better as it ages will the polycoats on all these other sugestions stay the same? or will it yellow checker flake off expoing cheap veneers and MDF.So for a loudspeaker to last a lifetime it needs to be built to and most are only designed for 15 years use.

I had a 50 year old pair of altecs 420y. Sadly one just died monday. I hang my head in shame.....But it can be rebuilt I can make it better than it was before better stronger faster;)
