Sounds like highlighting upper mid - lower height frequencies. 
The return of the DIYer
In 2001-2003, my friend and I traveled several times a week throughout Israel to the apartments of the audiophiles. At that time, I was looking for an amplifier instead of my Plinius 8200, the sound of which did not suit me then. Then I had Spendo... 
The return of the DIYer
Hi @mrklas ,I have a much more interesting journey that most audiophiles buying a new stuff. I always tweaking my amplifier, phonostage, crossover. I change schematics and parts. I customize everything for MY TASTE. And yes I have some background ... 
The return of the DIYer
I started my hobby around 1998. I changed components very frequently like many audiophiles. And around 2002 I finished with a system: Nottingham Spacedeck turntable, Cary 303 CD player, Plinius 8200 integrated amp and Spendor 2/3 speakers. I was ... 
Tube Power vs Solid State Power
Triodes have much less distortion and amplification element vs any type of transistors.Plus triodes have very low 3rd order harmonics vs transistors and pentodes.To get low distortion in transistor amplifier a deep global feedback should be used. ... 
Tube Power vs Solid State Power
1. IMHO height-sensitive speakers or mid- sensitive speakers in small room are must. Powerful amplifier with low sensitivity speakers is the wrong solution. Voice coil heating causes compression. More power you give  - more compression you get.2....

Single driver vs traditional 3 way loudspeakers
Hi @bache ,Thank you for explanation.I understand if you use full range driver you don't want to use it thought LPF.With most of compression driver - midrange horn combinations high frequency response drops relatively fast and without significant ... 
Single driver vs traditional 3 way loudspeakers
Hi @mozartfan ,High-Pass filter and crossover are the same thing!You didn't read my message. I told that 4th order crossover (HF filter) fixes most issues with super tweeter.I have to add that in case of forward-firing super tweeter placement sh... 
Single driver vs traditional 3 way loudspeakers
I used super tweeters with Altec 604E coaxial for many years.I also listened Altec 604E without super tweeters for couple of years.For last two years I use Fostex T90a super tweeters.It is always was some trade off between “audiophile” sound with ... 
Single driver vs traditional 3 way loudspeakers
Most of full range drivers have incline frequency response. And with a backloaded horn implementation they have a dip in lower midrange that causes dry and bright sound. To compensate it front horn should be added. A good example is AER big transp...
