50 vintage speakers that give odds to modern acoustic systems
http://www.audioheritage.org/html/profiles/lmco/shearer.htm They forgot the one that won an academy award for sound quality.  
Go get out your pitchforks, I’ve done a sacrilegious thing. . .
I had all 3 Schitt EQs they are extremely useful things if you have the need. The Loki is kind of veiled and you can hear this enough that it greatly limits its use. The Lokius and Max are far far less intrusive. Not like EQs of old. And are very ... 
Why do so many people have problems with bass?
Room size doesn't affect bass range even a car can support under 20hz as do headphones. Most bass issues are caused by overly small loudspeakers that have overly small baffles and little below 50hz many have a titled up response around 80-125hz so... 
Speaker positioning and center image depth
Bipole, dipoles, horns, dynamics, Omni, etc all have different radiation patterns, and that’s what mostly dictates proper in-room setups no one way or the highway. Best to understand how your loudspeaker radiates and interacts with room boundaries... 
MoFi controversy
My Mo-Fi LPs don't sound so engaging my Mo-Fi CDs do what a world.

Located S WI if you want to hear a bass horn. Not trying to sell just trying to help.

Yes, I built a good num of bass horns for Trio owners and a pair for my Duos.

Fixing 4 amplifiers may be costly and the 225 was one of the reasons I sold my Duos it never sounded as a whole. Maybe consider having a pair of bass horns built. I used bass horns with my Duos they became a far more enjoyable loudspeaker.  
Paper cone drivers/natural materials
Keep in mind unless ancient the paper cones today are not really all made of paper. And there are also many types of paper used Fostex for example uses a banana pulp some Fostex cones are hyperbolic paraboloidal shaped others use Washi or hemp-bas... 
The new dynamic in speaker pricing
There are great sounding loudspeakers and there are very high price loudspeakers sometimes the costly ones can be wonderful sometimes they are just priced high because that's how audiophiles think they greatly associate retail prices and name bran... 
Which pair of speakers changed your Hifi life?
http://www.audioheritage.org/html/profiles/lmco/shearer.htm Made me realize that we haven’t made much progress in overall sound quality since its invention. It’s still a world-class sounding loudspeaker and it’s over 83 years old. I’ve had anti-ho... 
Higher sensitivity - more dynamic sound?
{I see no physical mechanism by which a horn speaker would throw better than a dynamic speaker} You can not see the horn on a horn loudspeaker? Horns decrease SPL less at distance than a conventional dynamic design think radiation pattern control.... 
Higher sensitivity - more dynamic sound?
A 110db horn running off 20 watts will not see any heat that can cause compression a 86db speaker requiring over 250 watts will be near melting at peak SPL levels. A horn also has better throw so at distance, its SPL level isn't dropping as fast a... 
The new dynamic in speaker pricing
I build better horns than OMA and I don't sell them for new home prices.,  
Analog vs. digital
Analog and digital are just sources the more sources in my mind the more music you have access to. I still keep my CDs because most sound better than high-rez downloads and many are not on music services. I keep my LPs because I bought them they a...
