Morel, dynaudio, etc but expect to drop a mortgage payment.

Almost bought the x6c.. There $60 a pair. The mx60 is the top tier and its rd $120 a set new ship on 14th. Spec wise similar to x6 but softs are of much higher quality.

How is the mx60 claiming to be the loudest with only a 92 db?

1w1m means next to nothing man. I can build a driver with a 98db rating its going to be peaky and have a ton of breakup..

The higher the db the higher the volume per wat making it more efficient. Wouldn't design & quality materials reduce breakup?

i've had some 92 db drivers get louder than other 92 db drivers on less power so there's a lot of wiggle room on choosing drivers based on db sensitivity. I wouldnt base my decision making on the too much. The faitals are laidback and more veiled sounding mids, not very open and full sounding. not muddy by any chance but definitely not the best i've heard. crescendo UN series destroys the fk out of the faitals hands down. easily 3x clearer and 2x as loud. Cant say much about hertz since i have not heard them but I doubt they'd disappoint. Main thing is, you need proper processing via active bandpass capable crossovers with choices of -6 db to -24 at the least. Along with a 13+ band EQ to make them sound perfect. Dont expect a 3 to 10 band EQ to suffice... You need way more than that to control pro audio drivers.

This is why i like seeing a drivers frequency plot. Some drivers that claim whatever db rating will actually be the drivers peak frequency. Others are rated at an average. The problem is they will use a frequency range to give them a higher average. Your driver has very poor low end but a huge spike from 4-5k lets average from 250hz to 5.5k even though you give a frequency response of 80-6.5k. The best part is when you have to cross at 3k due to breakup above that and lose all of the speakers so called efficiency. For $45 a driver the faitals a great. The Crescendo uns are a bit more but have a huge efficency bump in the upper midrange at a loss to midbass but are crossable much higher than the faitals so it is usable output prv also makes a neo very similar. The un being able to cross no problem at 5k opens up more tweeter possibilities.

Great info guys ! Tuned in !

No 6.5 should cross over 3k.

Why is that ? go easy i am a noob to understanding speaker specs.

Look up speaker beaming. It's determained by the size of the cone. Basically the speaker goes from a wide dispersion to a straight line.

Please excuse my ignorance but what I am getting is that a certain amount of beaming is needed and different cone size it will beam at a different freq ? And I am guessing 3k is to low to produce said beaming on 6.5 speaker ? Feel free to correct my limited understanding.

Beaming is unwanted. frequency tables

Guess I got that totally azz backwards !

Ok I found this in a post on DIY about beaming and I think I get it now.

A loudspeaker is a vibrating piston. For a vibrating piston the on-axis radiation can be simplified as the sum of two two plane wave signals of the same amplitude. One coming from the center of the piston and one coming from the edge, which is often called the "edge wave." This edge wave is 180 degrees out of phase with the primary signal coming from the center. When the combine you get beaming as wavelength approached piston diameter.

Now looking at the chart you posted it says for a 6.5 speaker it should be limited to 2672hz so 3k would actually be too highcross over point ?

One of the reasons I posted this thread is due to the frequency graphs of the Hertz vs the Faital. The Faitals seem more linear, have less breakup past 3k and have a lower fs. At a $147 bucks cheaper a set it seems like a no brainer, but why? I'm still learning so I figured id ask and see if I'm missing something. Now I'm starting to see opinionated replies across different threads of who ***** and why. Some point to a certain brand as the go to, then others state there ratings are blown up and over priced. I have yet to even ask about the tweets and learn how to choose those to complement said drivers. Hell ive never ran a system active before so this is one big adventure!
