15 in full range drivers

To suggest that a full range driver coupled with an SET amp is limited to vocals or a small segment of music is just not true for many of us. In fact, quite the opposite.  I have two systems that could be not more different.  One has Tekton DI's coupled to a pair of HSU 15 inch subs powered by Marantz Ruby electronics.  Very little that system can't handle.  My second system has a pair of Omega monitors driven by an Erhard Ray 6L6 SE integrated.  I can listen to a large part of my music collection on this system all day long.  No fatigue.  I dare say I might listen to this system more than my other--but I love them both.

@zagorskia  what 15" driver are you using?

@corelli  At volume does your Tekton system start to outperform your Omega system, playing something like rock or orchestral?  70db?  75?  In OPs own words he describes his system as fatiguing.  And your suggestion is what, grin and bear it?  Maybe read more "expert" opinions on the virtues of single drivers and low watts?  There is nothing more audiophile I guess then building a system that mandates a ton of excuses that only a handful of people would appreciate.  

Just a FYI. When a speaker is considered bright or fatiguing, it is hardly ever high frequencies that are the culprit. More often than not it is the upper midrange.

@czarivey 

Pretty stupid statement. My 300B amp sees a regular diet of metal, hard rock, big band, Latin jazz, and a whole host of stuff that requires some grunt. Never breaks a sweat. 

Not really @ozzy62 

I hate increased upper mids and all 300b or 2A3 amps are notorious for that. In fact all they amplify is 1000 Hz. The rest is not so much.

@perkadin   It is a bit hard to respond to your question. This has nothing to do with decibels.  It has everything to do with the virtues of different approaches in reproducing the music we love. It has everything to do with component matching.  I never told the OP to "grin and bear it."  I questioned his choice of components and how well matched they are.  You clearly have your preference and I have no interest in trying to lure you away from what you prefer.  But for others out there who are more open minded, we should not write off different approaches to music reproduction.  There is no one perfect answer.  Most everything in life has a pro and con.
