Dayton Audio RS28A-4 1-1/8" Aluminum Dome Tweeter
How is this tweeter different than the RS28AS-4 tweeters that I currently have ?
There will be no audible difference between the two, the one you have has magnetic shielding and this one doesn't.

It's a good replacement for Celestion 300? Spec.: Two-way transmission line loudspeaker. 1.25" aluminum-dome tweeter, 6.5" polyolefin-cone woofer. Crossover frequency: 2.2kHz. Crossover slopes: 3rd-order Butterworth, 18dB/octave, 8 Ohm - 84db
This will work at that crossover frequency without a problem, but you will want to use an 8 ohm tweeter in order for that crossover point not to change. Please contact our tech support for more help with this question, email@example.com or 800-338-0531 x1.

Are those SPL (sound pressure level) numbers? If so, they are much lower than the 94.4 db on the specification sheet at the Parts Express website. One of the decimal was red marked. What does it mean? What was it matched to?
The manufacturer measures these tweeters with 1 watt as opposed to 2.83 volts as specified on our spec sheet. This will account for the difference. The checked decimal number is the tolerance. For example, if the number in the box is 90 and 0.4 is checked or marked, that tweeter sensitivity is 90.4 dB at 1w/1M.

On each of the speaker, there is a sticker with a bunch of number on it? A single 2 digits on the top row and a series of decimal numbers from .6 to -.6 below. The 2 digits number above the row of decimal numbers is 90 on one and 88 on the other.
These numbers represent the sensitivity tolerances of each driver. For example, if one tweeter reads 88 in the box, and 0.4 is checked, that tweeter is 88.4 dB sensitive.

Does this, as well as most other drivers and tweeters sold come with mounting hardware?
Unfortunately this along with most other drivers do not include mounting screws.

CAN it be à good replacement speaker for Energy Pro monitor 22?
