I don't know what the official efficiency stock rating of an '87 sda 2B is. When I 1st got them I used a speaker selector which is frowned on by some here. The setting that most got use was 10/10:30 on my pre and any more would just be getting to loud. I've done about every mechanical mod there is and one technical I did not. Adding the Dynamat, rings, spikes and now going down to a 10 gauge Belden speaker cable from Blue Jeans I find going over 9 now is shaking the plates a bit. Does doing all the mods, which seamed to pay off and not for that much coin in the big picture equal more effenciency. Now not doing the x-overs might limit this whole question of efficiency but. I have undone the selector for the time being and going straight into the Adcom,reason 1 to test that more gear upstream is no good and 2. a 10 gu won't fit the selector.

That's all fine and I get that but why such a difference and noticeably between both speakers. Really not complaining here just want to know 1 side would act so differently and nothing is heard at any level to lead me to think anything is wrong. Maybe nothing, but if that hands on pressure test is valid then somethings going on. Even a better question now, you know how you can do a draft test in your house, is there any way to find if it is seal where it is.Like I said all gaskets were redone so I doubt it's there.2chl- Adcom GFA- 555-Onkyo P-3150v pre/amp- JVC-QL-A200 tt- Denon 1940 ci cdp- Adcom GFS-6 -Modded '87 SDA 2Bs - Dynamat Ext.- BH-5- X-Overs VR-3, RDO-194 tweeters, Larry's Rings, Speakon/Neutrik I/C- Cherry stain tops Advent Maestros,Ohm model E

You may have a little more low end, but as far as the speaker as a whole being more efficient, it's very unlikely."He who fights with monsters should look to it that he himself does not become a monster. And when you gaze long into an abyss the abyss also gazes into you." Friedrich Nietzsche

I don't personally think speakers are getting more efficient.
But I have a pair of Klipschhorns and nothing is efficient compared to those monsters. -
Louder sources? Toe in-out? Listening distance change?Oh, Listen here mister. We got no way of understandin' this world. But we got as much sense of this bird flyin in the sky. Now there is a lot that bird don't know, but it don't change the fact that the world is happening to him all the same. What I am tryin to say is, is that the course of your life, well its changing, and you don't even see it- Forest Bondurant

I have NO problem believing that ancient electrolytic capacitors could suck the life out of your speakers, and replacing them with fresh caps could bring the volume level back up to what it should have been.
It seems you haven't replaced the caps yet, though.
Maybe you managed to seal an air-leak in the cabinet, and you're now getting the bass you paid for--which brings the volume level up, along with the vibrating dishes.
Maybe you managed to clean some corrosion off of the wiring or connectors, making for less resistance??? Or your speaker switchbox has high resistance, and you've eliminated that. You now have 10-gauge speaker cables...were the old ones 24 gauge?
