It's possible, but I really can't say for sure. While I've taken IR data from two different DR speakers, I've never bothered to determine their maximum SPL capabilities. I will say that IME you've gotten the maximum clean SPL from a Deluxe with the volume somewhere between 3 and 4. Above that, it gets distorted and not a whole lot louder.
I was basing my assumption on 30-ish watts output leading to, what, 15-ish db above speaker sensitivity? Maybe my wattage assumptions for a DR on 3-4 are off.
Nowhere close. The numbers you see for jet engines on SPL graphics are the SPLs a listener is exposed to. How close will a listener ever come to a jet engine? The max-SPL figures for speakers are referenced to a 1-meter distance from the speaker, i.e., at a position a listener will never occupy. If the meter in the photo above represents the output from just the speaker, it will produce 110.9 dBSPL at two meters, 104.9 at 4 meters, etc. Still loud, but quite unremarkable as 1x12 speakers go.
If you are driving a quad box, sensitivity at one watt is up 6 dB relative to sensitivity for a single speaker. So 106 dB at one meter for a box of 100 dB V30s for example. For a twin like an AC30 then 103 dB at one watt.
That statement assumes coherent summation of acoustic signals from all four transducers. Assuming the same impedance load as a 1x12 - e.g., series-parallel with 8 ohm speakers - this is the case directly on axis, but not elsewhere. I really do mean directly on axis. At even a very few degrees off axis, the coherence begins degrading, first at the highest frequencies, then (at greater angles) at steadily-decreasing frequencies. The added sensitivity only holds up reliably at lower frequencies.
Attempts to compare peak SPL capabilities between a tube guitar amp and a neutral monitor have serious limitations. The tube amp will keep getting louder once you start overdriving it - and the distortions it produces when you do that are usually intentional and desirable - whereas a neutral monitor must remain clean, no matter how hard you're pushing it, since you're getting all the nonlinearites you want from the modeler. This is one reason that maximum clean SPL is so important for a monitor. You don't ever want to drive one into nonlinear behavior.
DR was short for Deluxe Reverb
Psshh. Everyone knows it’s short for Dual Rectifier.
Didn't you mention a 103? Maybe that was a sensitivity figure.
I did not mention 103 anywhere in any way. But I did expressly state "Deluxe Reverb" in the original question to which Jay and I then shifted to short-hand "DR".
(Present company excluded, of course. Drew is a dashing man)
No.
Why would it not fit they are identical to the Fenders ? just different aesthetics no ?
It should work. I don't want to be first.
