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.

Thankyou, Charles! I now have two 8ohm cabs. One is 2x12, one 4x12. No more confusion!

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. 🫡

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.

Thank you very much -- that is exactly what I need!

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.

Sounds great man! What kind of amp do you use in this video?

@ChadEtchison Жыл бұрын

Thanks, Jens! The amp was a kit -- it's a GDS 18 watt recreation of the original Marshall 18 watt circuit. gdsamps.com/amps/

@Black1ce8 Жыл бұрын

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.

Think we're al Dum Dum's when it comes to matching ohms. Sounding good! That Lollar Bridge pickup is special. Keep rockin!

@ChadEtchison 2 жыл бұрын

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.

The ohms depend on how you wire them, not necessarily what ohm the speaker is.

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.

@charlesfick729 2 жыл бұрын

It’s exactly right. The lower number represents less resistance to match the load output of the amplifier

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!
