Speaker dB's

[Willabe]

How much audible difference will I notice going from a 99dB speaker down to a 96dB speaker?

It would take 6dB to cut the perceived volume in half?

So will a 3dB drop be;

1. Just slightly noticeable?

2. Fairly noticeable?

3. Clearly noticeable?

4. Or very noticeable?   

As always, Thanks guys.

fwiwfor guitarist.
1...maybe 2


for cork sniffing.


2...maybe 3


I went from an audio system with basically 88db setup to 92db, my 'old ears could hear "clarity" well but volume wasn't much.

It’s the same as halving the amplifier power, eg going from a 50W to a 25W amp. Crank it and trouser flap will be slightly lessened 

Halving the volume is a different thing, typically noted as requiring a 10dB power reduction, 1/10, eg 50W down to 5W.

To me, that's very good as far as taming an amp down some. That will be very noticeable to me and should help a great deal for playing at home.

I took the plunge and bought the new Magnatone Twilighter Stereo amp, head and 2 x 12" cab. 22w's a side, PP 2x6V6. And this thing is tooo loud for at home!     

I wanted the Maggie pitch shift vibrato. The amp sounds great, but man, too much! I want to play it clean with my Gretsch Falcon and the vibrato. That guitar with the TV Jones Filtertrons and the Maggie vibrato, it's a wonderful sound. When the vibrato is kicked in to stereo, it gives it a 3d depth with this watery flutter. Sounds beautiful to me. Just stunning. In mono, ehhh, sounds good but not near as impressive sounding.

I don't need to go all the way down to a 5w amp. I play on the clean side so only 3.5 to 4, maybe 4.5 or so on the volume for what I want to do with this amp. I have a little Champ/Princeton SE I built for dirt if I want it.

I think I'll go ahead and buy a pair of 96dB speakers for this amp. I'll let you guys know how much it helps after I get them installed. 

Thanks guys.

In my recent speaker experiments I have found something that is news to me and might help you.
It seems to me that every lower sensitivity speaker I try is missing highs that are more present in higher sensitivity speakers.
Maybe it's the way my ears are perceiving it, but it seems to be across the board.
This obviously isn't very scientific, but it's what I'm hearing and not hearing in real life.

It's as if the highs are dampened in the lower sensitivity speakers as a result of them being lower sensitivity. (if that makes sense)
Mids are more pronounced, but overall it's as if there is a "blanket over the speaker" effect, in all of the lower DB models.
Maybe it's just a blanket over my ears? 

And, maybe in your scenario, less highs is a good thing?

EDIT:
Do yourself a favor and don't go down the speaker efficiency vs frequency response rabbit hole that I just did.
Save yourself some time and money and just throw a blanket over your amp.
Oh, and by the way, my answer to your first question is #2

missing highs that are more present in higher sensitivity speakers.

agreed
the "clarity" above, was hearing a fuller audio spectrum with higher SPL speakers.
still working on the Bass amplifier for the woofer "feel"
