Are all dBs created equal?


I recently purchased new speakers and I have run into something interesting. With my old speakers I listened at 80 dB average and it was comfortable. At 80 dB average with the new speakers it seems much louder and I have to turn it down to 70-72 dB to get to my comfort zone. Why would 80 dBs sound so much louder with the new speakers? FYI, the new speakers are presenting more detail and refinement. The sound stage is better in every way. What gives?

The Aria bass boost is pretty large and the have a fairly flat response up to about 15klz so I can see why you might need more SPL at a listening distance of 8ft or so. I have no idea about the Tyler but as I said they could have a nice smiley face frequency response which most people ( not all) would find fatiguing hence the reason for lower SPL. I would ask the builder for an anechoic FR on these things before buying but that’s me. I never purchase without knowing what EQ or room treatments I might need.

Depends on how the dB measurement is reported.

There are two common methods.  They may differ (despite being the same number) in actual sensitivity depending on ohms.

dB 2.83V/1m or dB 1W/1m

If we are talking about measured audio dB, then this article may start to help:

Lastly though, the Focal seems to be tuned "loud" but they are also notorious for having difficult impedances around 100 Hz.  Depending on your amplifier it may seem bass shy.

That’s for speaker measurements. If the OP is talking about the sound pressure at his listening location that is different.

 

Efficiency is about output per watt, so 1w/1m is used.  The input voltage is adjusted based on the impedance.  It's also kind of a PITA to measure so often done at exactly 1 kHz.

Sensitivity is about output given an input voltage, so 2.83V/1m is used.  In this case the watts could be much higher or much lower than 1.  There's no guarantee.

The two are equivalent only if the speaker is exactly 8 Ohms, but in either case the SPL is measured the same way.
