Actually, he's not incorrect. You guys are talking about two different things. One is talking about unexpectedly high sound quality from a small and inexpensive speaker intended for moderate SPL with limited low end and limited acoustic output, and the other is talking about speakers with better low end and can produce more acoustic output for a larger room.

You have written that they're great when playing a female singer and acoustic guitar, and not so much for "bombastic" orchestral music. C'est la difference!

IIRC, the lowest note on a typical acoustic guitar is E2, around 80 Hz. The lowest a typical female singer sings is around 200 Hz. This is a huge difference in required low end air movement from a bass drum or timpani in an orchestra.

One last comment... One person's "excellent" sound can be another's "reasonably decent". It depends upon the standard being used.

these co-axial produce more bass then I can handle as it is ..... its clean coherent, deep and ultra fast and they go down to at least 35 hz ,,,,, they produce chest pounding bass ,,,, these things are in different world then the old time passive minimonitors ,most people on this forum have heard .... they will do deep powerful timpani drums with no sub woofer required and the transient speed is breathtaking
someone else buy these and post to this thread ,,,,, they can be bought with a 14 day return policy on Reverb.com ..... they can be bought for 500 to 600 dollars .... or basically what you guys spend typically on a single power cord for your systems

  It's great that you're very happy with these speakers.
  But don't confuse your satisfaction with how they perform objectively.
  Often, people think they're hearing "deep" bass, when actually, what they're hearing is accentuated upper bass, which is generally in the range of about 125 Hz to about 250 Hz. This range gives the "punch" and definition to bass, which many people perceive as "deep" bass.
  Next, let's look at air displacement. A 6.5 inch "woofer" typically has about a 5 to 5-1/2 diaphragm. As I wrote at the beginning of this post, it's great that you're happy with your new speakers. Just don't be disillusioned with what they are doing.
  Especially at low frequencies, output is all about moving air - a lot of it. Look up the term "acoustic watt". This is a measure of how much sound power is produced by a sound source. "SPL" is secondary, and is intimately related to the measurement distance and position, the size and shape of the space, and the absorption coefficients of the space.

    I got sidetracked into the difference between acoustic power and SPL, and then forgot to note why acoustic power is important. It's important because it's a measure of how much sound the driver is actually putting out, regardless of the measuring distance or environment. And, this can be calculated by a simple formula (which I don't have in front of me at the moment), which basically uses the area of the driver, the one-way excursion, and the frequency to arrive at acoustic watts. Be aware that, for home uses, this will likely be a small number - less than one acoustic watt.
    
    Maybe Tomservo has the formula memorized and will post it.

  to hear that. Evidently, you've never heard live concert drums, string bass, pipe organs, etc.
  
  35 Hz to 20 kHz frequency response
  
  Plus or minus what?
  
  Do you really believe a 6.5" driver can produce flat response to 35 hz?
