Two 8 ohm speakers Series you double it or 16 ohms. Parallel cuts it in half, you’ll get 4 ohms. 4 x 8 ohms to get 8 ohms, you run both sides in series which gives you 16 ohms per two speakers then, you run both sides in parallel which cuts the two 16 ohms sides down to 8 ohms.
Just for some personal experience, I have the same cabinet and bought 2 Celestion Gold speakers to replace the originals (same Ohms) and it sounded awful. Very fluby, flat and choked (ended up putting 2 Vintage 30’s… worked great!) I took them out and put them in an open back 2x12 vintage Carvin tube amp and they were absolutely glorious! Gold’s don’t seem to like closed back 2x12’s for some reason… Great video. 👍🏻
Oh man, that is great info! I was wondering about the Gold's -- a lot! I was thinking of doing the G2H30 and Blue combo. I will probably make another vid about setting the cab on it's side I have discovered that it sounds a little better somehow in the vertical position.
@@ChadEtchison I’m not sure why these speakers didn’t perform as well in that smaller closed back cabinet. Celestion Gold speakers are fabulous! Just not well suited to it I suppose (in my experience). Good luck my friend. 🫡
Remember., the amp needs to be the same or lower impedance than the cabinet. If you have an amp and the cabinet is giving MORE resistance, that's okay. If you have an cab with less resistance (8ohms for example) than the amp (16 ohms) that current will run flat out through the speakers and possibly damage them as they aren't providing enough resistance.
Great info here for something I’m just getting onto - picking up my 1936 tmw - sounding great here . I appreciate how you can just let a chord ring bro
The relevant equation for guitar amp impedance is 1/R(total) = 1/R1 + 1/R2. So two 8 ohm speakers would be 1/8 + 1/8 = 2/8 - reduced to 1/4 or 4 Ohms. If you target is 8 ohms total the 1/16 +1/16 = 2/16 - reduces to 1/8 or 8 Ohms.
Product over the sum for parallel circuits. 16 x 16/ 16+16 = 256/32 = 8 ohms. Dividing by the number of speakers is not an accurate formula. It won't work for 3 speakers for instance, or if you have an impedance mismatch. Product over the sum is how it works.
Man, I have to be the dumbest. It sure was a relief to know that it does sound correct with the right ohm match, because in 16ohms, it was a fuzz box. So weird. Now I have speaker fever. I will probably replace both speakers with some fancy ones. My justification is that I don't buy pedals, so I have to do something, haha! Don't ya think that bridge is nuts? I think it sounds incredible, so I'm glad t hav you confirm it. I don't know what they did with that one to make it sound like that.
I know nothing but I do remember someone saying with ohms you can go bigger but not smaller. Apparently if you have an 8ohm output you can use an 8ohm speaker or 16ohm but a 4ohm will blow up your amp. Apparently. Which of course to everyone seems backwards. You would think smaller would be safer but it's not. Again, apparently.
Holy cow bro! Please watch a legitimate tutorial or video on ohms, You have it way off, you are going to breaks something, i understand ohms law and how to wire speakers, I can not , nor do I want to explain it. It is pretty easy as far as guitar cabs and speakers. Home audio and car audio can get a little confusing with lots of speakers. Please look it up!
