[@michaelreyes9997]

Way to much talking

[@redgamer821]

Please remember, like with car amplifiers, your head will not be sending a constant power of 800W to your cabinet at all times. This is simply how much power will be sent when operating at full volume (assuming the power ratings of your head and cabinet are the same). So if you are at only 20% volume, your head is definitely not outputting 800W to your cabinet, but instead much less (ex. ~200W). So like mentioned in the video, it is alright to have a head with a bit more power than a cabinet can handle, you just have to make sure to not drive it too hard and make sure to match the impedance.

[@PhilGreis]

I've been playing for over 40 years and never paid attention to this stuff. Thanks for enlightening me.

[@hermonbluesmaclin-theboogi6830]

I use a Mark Bass Jeff Berlin Combo 15 and a Mark Bass 2X10 as an extension cabinet. I can also just use the 15" combo solo. I bought a Mark Bass amp to power the 2x10 cab for gigs that it'll handle. That way for the big gigs, I stack the 2x10 on the 15 combo but use the other head on the 2x10 giving me 300 watts per cabinet. I run a line out from the 2X10 head to the balanced line in on the combo amp so each cabinet can have it's own unique sound . That configuration gives me the ability to dial in super lows, crisp highs and punchy midrange because each cabinet has it's own amp and eq etc.

[@yeewhiz]

Is your amp head a little mark ii ? What ohms do have your 2x10 and 1x15 set at when stacking to give you the 300 watts per cab ? (Just curious , didn't know it was possible)

[@hermonbluesmaclin-theboogi6830]

@@yeewhiz Little Mark III and the 2x10 is 8 ohm. I only get 250 per cab when stacking but I often use two amps with Little Mark III powering the 2x10 cab and the Mark combo powering the 15, that's how I get 300 per cab. I use a separate amp for each cab and run a line out from one amp to the XLR in on the other. Each amp is 300 @ 8 ohms. Really cool with my Rickenbacker in stereo giving me one pickup per cabinet. Using 2 amps gives me the ability to have two totally different EQ settings for each cabinet too.

[@hermonbluesmaclin-theboogi6830]

@@yeewhiz I use a Mark III with the 2X10 and the Mark combo amp with the 15. They both put out 300 @ 8 ohms. When I'm running both cabs off the combo head it's only 250 per cab. Using two amps gives me the option to use a different EQ for each cab too. Pretty cool. I just run a line out from one amp to the input on the other and then balance the volume as needed. Really cool with my Rickenbacker in stereo mode too. I have one cab and amp per pickup on the axe.

[@yeewhiz]

@@hermonbluesmaclin-theboogi6830 Thanks for the insight. I recently got the 2x10 because I like the clarity with the higher tones. I've had the 1x15 cab for a while and decided to get a 2x10. They both sound good for the purpose they serve. I was just curious to try my little mark III on both amps. Having an amp for each for different EQs makes perfect sense.

[@MrRawnch]

The information at 7:10 is wrong. Daisy chaining is still parallel and doing so with two cabs of matched impedance (8+8) will total 4 ohms.

[@chrisfoster7807]

I have a MESA 8 10’s Bass cab that has the parallel out that you mentioned and I would usually put workingman’s 410s behind the Drummer . What a great thing that MESA has included in those old cabinets, I wonder if they still do.

[@Theweeze100]

This was great. When I was a kid playing bass back in the 70s, I used to beat my head against the wall after blowing up bass cabs. I now have EV’s an old SWR basic 350. Burgundy face. It’s good down to two ohms, has a tube pre for warm sound, and you can find them for about 300 bucks all over the place. It’s a steal, grab one if you can. 450 watts at two ohms.

please explain Clay , how come compos have an 8 ohm speaker in them ? do they run at half their nominated power ? thank you

[@robertbales3030]

You would need to check the specification sheet for your amp. But, with combos, generally, if it has an "external speaker" port, then it runs at about half power. Add an external cab and you will get full power.

Great explanation of how things work. It's something I had explained to me years ago and I did the physics whenever I wanted to try something new. It helped me learn things. If this video existed back then, would have saved me time and effort. LOL! Great job! I run an Ampeg SVT-3 Pro through a Trace Elliot 1048 (4x10 cab - 8 ohms) and Trace Elliot 1518 (1x15 cab - 8 ohms). The cabs have "Input" and "Link" inputs. Use "Input" direct from the amp and "Link" for a stack. Great tone and volume no matter how I run this setup.

[@jmlon993]

so for your 2x10 cab you basically "daisy chained" an attenuator of some sort to increase the resistance to that cab? can you explain in more detail?

[@rayyoung3882]

Thanks for this Clay. I sort of knew what goes on with impedances etc but your brilliant explanation has filled in or the gaps. As a guitarist & bass player there is one question I have never had an answer to. This is as follows....WHY does a 100 Watt VALVE amp sound so much louder than an equivalently powered SOLID STATE amplifier? I use both kinds of amps & there is definitely a huge difference audibly. In other words why is a valve watt seemingly louder than a solid state watt? By the way I use a Mark Bass 800w amp head with a tiny pre-amp valve that can be dialed into the mix. I also use a Mark Bass 4x10" which is rated 4ohms. I believe this is similar to your rig in one of its configurations. I would like to add a 15" cabinet & bi-amp the 2nd system to keep the impedances correct but carrying this gear will be ridiculous at my senior age. The speaker magnet technology has improved massively & Neodinium ceramics have lightened cabinets somewhat. However the cab size situation has not inproved that much so I would still need a truck to carry this gear :)

[@chizorama]

Good question, I saw that tubes are louder than solid state(on a guitar amp vid), smaller tubes powering the big tubes, but I don't remember the exact reason. What I do know is that tube amps are a helleva lot heavier, haha, ugg.

[@gooble69]

> WHY does a 100 Watt VALVE amp sound so much louder than an equivalently powered SOLID STATE amplifier? Because Watts are not really a great way to measure volume.

[@robertsands5837]

I'm pretty sure all bass cabinets are wired in parallel which means if you daisy chain 2 8ohm cabs, it becomes a 4 ohm load. if they were in series, it would be a 16ohm load. Maybe I'm wrong as I'm not a rocket scientist, but that makes sense to me. The rest of this video is spot on.

[@MrLanders2000]

[@Hondo99]

I dont know why people buy combos unless you live in a apartment. Save a little longer and get a 4x10 or 2x12 and a head. Then save more money and buy a 2x10 if you want portable. Combos in my humble opinion are a waste of money for bass players. My 4x10 sounds luxious even at low volumes. My drummer works cement all day so I don't bitch about lugging a 4x10 to a gig. Its worth it. The Heavy good shit is harder to steal too lol.

[@paulholmes5240]

When you say that you are running the two speakers in parallel do you mean in two separate speakon sockets at the back of the amp , if you do a lot of amps only have one socket so what do you do then ? Sorry if I’m being thick lol

The sub-woofer has a DI through which I intend running to another identical powered 18" sub-woofer as they are separate powered units I kind of guess no problem? Certainly haven't had a problem running 2x10, 1x15 & 1 powered 18 sub from the DI as yet but in house I'm not running above 2 on the volume knob. In case your wondering why - my modified bass is tuned an octave below normal so it starts at E0 i.e. 20Hz.

Brilliant and very interesting...but will have to watch it again

[@beornthebear.8220]

Solid State amps can usually run at 4 ohms (the old Sunn Coliseum could run at 2 ohms, which will blow most amps out, but Sunn went out of business some years ago and they are hard to find now). I run a Mark Bass head that puts out probably 500 watts at 8 ohm, but I run another cabinet out of the second output. I have a 4x10 cab at 8 ohms, and a 1x15 cab at 8 ohms, so that running in parallel, total 4 ohms, which allows my amp to run at 4 ohms and puts out 800 watts. Tube amps with an output transformer may be able to handle a little more variance in the output impedance, but if I ran my Solid State amp into 2 ohms, I would likely toast my output transistors. I have yet to use 800 watts, as this would be very loud. My 4x10 is the same Mark Bass cabinet in your video, and my 1x15 is meant to handle 350 watts, so I could possibly blow it out if I went full throttle. And when you're pushing a cabinet to it's rated wattage, you may still overheat and blow out a speaker. If your speaker is making scratchy distortion, you can gently push on the speaker cone. If you hear scraping, you have blown your speaker. If it won't move at all, you've sent the speaker into total meltdown. If I so blow my 15, which is unlikely saying I have only played small venues and have more than enough power. I will probably replace it with a Neo 2X12 cabinet.

[@ampeg187]

I'm planning to connect a second 2x10 8OHMS 400W bass cabinet do my Little Mark 3 head. From their FAQ it was said that from each head speaker output i connect 1 cabinet as showed at 8:24. Or connect one of the speaker output to the first cabinet and then link it to the second cabinet again as showed 7:19. But it doesn't mention nowhere about the doubling of the impedance to 16OHMs or that will run quieter if i connect cabinet to cabinet it just says that either way you connect it you will run at 4OHMS but you say otherwise. You also have Markbass setup so please let me know what should i do. This is really weird i guess it should have worked great/same either way. Thanks

Why not just use the 410 for the small venue with the volume backed off, the 410 for the medium venue with more volume, and two 410’s for larger venues. FWIW, I acquired this 410 recently. The amp is 1000 W and is on back order till December ‘24. Hopefully that’s just a placeholder. I think the head you’re using is the 800W tube head. I’m not so sure on the tubes.

Other than offending other bass players do you think this is an advisable pairing spec wise?

[@chizorama]

I've done that, but splitting the difference, like he explained here, I found that I wasn't getting the best out of either. I always ran with 1 15, but I wanted to add a 2×10 so that I might actually hear myself over the obnoxiously loud guitarist I've played with. I dabbled with a 4×10, but I like the heavy hitting of a 15. That being said, the best bass cabinet I played was an old 2×12 offset.

So I also went with Markbass speakers, and I'll be hooking up a 4x10 markbass cab up to an 800W Little mark head, and plan on getting a 1x15 cab as well. Looking at the back of my amp head, I see two outputs, one that says Speaker Cable and the other that says "Class 2 Wiring", does it matter which cab is connected to which output or not?

[@austinwolfe9501]

Doesn’t matter. Class 2 Wiring just means it’s generalized as safe from electrical shock and doesn’t pose a fire hazard under the electric code. They’re both speaker outs. The LM 800 tube amp just gives you two different speaker output options: the top one being combo jack of Speakon or 1/4”and the bottom one being the regular 1/4 inch (which I actually wish they would have just done both Speakon jacks). Use both of them, one going to one cab and one going to the other, and you’ll get the parallel circuit he’s talking about in the vid. I actually have the same setup, so here’s how it would look: Top (Speakon) speaker output jack running a cable to my 4x10 cab. Bottom (1/4in” jack where you saw ‘Class 2 Wiring’) running another cable to my other 2x10 Traveler cab. Now both cabs are separately connected to the same amphead instead of amp to cab then cab to cab (daisy chain). Keeps it Parallel. DISCLAIMER: According to Markbass themselves, it’s safe to daisy chain so I don’t know who’s right or wrong necessarily. Nerds are gonna nerd.

Hi there. Can you connect the bass guitar combo to a mixing table using a cable or is it better to use a microphone placed in front of the combo as you normally do with an electric guitar amplifier? Blessings from Porto, Portugal.

[@Thisonegoestoeleven666]

If your head has an XLR out or cabinet emulation out then yes you can connect direct to a desk. If your amp doesn't then it will need to Mike up your cabinet. It will sound bad if you connect direct. Also if you run your amp with no cabinet resistance from the speakers you can damage your amp due to too much current. Always have a cabinet connected to your amp, even if you are going direct!

Thankfully it died at home during practice - blew a fuse, which blew again after replacement within minutes. I spent a few hundred to have it repaired and the same thing happened again, within minutes. After having it repaired again I brought it to GC (where I bought it) and traded it for a couple of other amps.

I did discover that my Behringir BXD 3000H Ultra Bass Amp Head is rated at a minimum 4 Ohms and 300 watts and 180 watts at 8 Ohms. My Ampeg 2x10 Portaflex Cab is rated at 8 ohms but wired in parallel so I can actually connect two 8 Ohm cabs and get the full 300 watts Does this make sense? Thank you again.

[@ClaysBassLessons]

Man, this stuff can do ya head in. Hope that helped you guys out if you were really struggling to understand Cabinet and Ohms. I will add here that on more research it seems that MOST cabs tend to have Parallel connectors and just don't state it on the back but not ALL! So if you aren't sure if they are or not always connect each cab to the Amp Head individually to play it safe. Only Daisy chain if you amp head only has one output and you have to.

It really would help if he were speaking American English. In addition to the subject matter being a little confusing, and fast talking, there is a language barrier. However, I do appreciate the attempt to explain.

I had a semi tube (those fake tubes) 60 watt custom build (originally owned by my uncle) bass amp with a yamaha 2x15 and 2x10 hartke combination... The speaker blew and i was about 17 so i ditched the amp completly... Ran a hartke lh500 with a 450 watts 4x10 after switching that up by buying my guitar players peavey tmax, tore out the amp and used my 4x10 with a 1x15 mix. Thats still owned by me but i switched to a markbass amp with a mesa 6x10+1x15 and there i hit that sound that i want!

[@edwardh4202]

as I am shopping for a new rig. I have a 3 part question.. your amp is 800 @ 4 500 @8. If you have an identical 410 cab will the 4 ohm version seems louder then the 8 ohm version by itself? will running the 4 ohm give me more headroom and volume?

[@siftedsoul]

Running more speakers with two 8 ohm cabs will give you more volume than running one 4 ohm cab with a higher wattage vs the 8 ohm speaker .

[@petewookey3635]

Hey you mentioned towards the end about the impedance increaser your friend made so that each 10inch speaker would get the same power. Is this absolutely necessary or is it more of an "OCD" thing? Because the way I see it, the 210 should be ok with the 400watts, despite it being annoying that things aren't balanced with the 410 cab.

[@siftedsoul]

He wanted the applied wattage to each cabinet to be the same so the sound would be more balanced.

[@Hellion73]

Got it about the omhs, still have a doubt about the wattage, cos i own one amp of 4 omhs and 300watts and 2 cabs of 8 omhs, one of 300watts but the other has just 150watts. Do I risk to damage the 150watts cab if I connect both cabs in parallel to that amp???

[@petebjerkelund5088]

2 Ohm Heads I have: Fender Rumble 800H, Yorkville XS800H and SWR Redface 350

[@labrosts2435]

Hi clay, Im going to buy a new rig and I'm looking at the tc electronic bq500 amp and their k-212 cab what do you say about this setup ?

[@Thisonegoestoeleven666]

Good setup man. The TC stuff is sounding great at the moment. Also have a look at the GK ultra light stuff. What sort of stuff do you want to play? That will really determine your amp choice.

[@mrarafat]

What if your amp say 2 × 400 watt @4 ohm parallel?

[@mrarafat]

Two speaker of 8 ohm like you say?I'm a kind comfused there.

It looks like you are a markbass fan :) In your opinion, which markbass combo is the ultimate one ( for practice and gig ) ? 😉

[@runnningonempty]

THE BIGGEST YOU CAN AFFORD..THE MARK HEADS DONT SOUND DIFFERENT ENOUGH TO EVEN WORRY ABOUT..THE MORE DRIVERS THE BETTER...

[@Thisonegoestoeleven666]

102 will have you covered for most stuff. Have a 4x10 for bigger gigs if you need it. You will be surprised just how much air the 102 combo can move!

[@zacharybrown5150]

So I should get an 800watt 4x10 at 8ohms?? And use that by itself and then get another one if I want a stack? #Zakkane #D3ADRAT

[@Thisonegoestoeleven666]

Hey man, nice vid. Was trying to explain this concept to my guitarist last week. Dusting off the old physics formulas, good fun. I have a Mo'Mark 500W head with the HE tube preamp, and a 104HF cab. Saving up for a 151 cab to put underneath for the monster rig. With my Sansamp it sounds mega!

[@TheHyperspace2000]

Good explanation. But why do you shout it? It’s really hurting my ears.

[@jonathanbrown6221]

Just stumbled across this! Nice one bro, great stuff!

[@chuyreyesdiaz]

What’s up brother, this is actually the first video I see from your channel and best believe I subscribed, I have a quick question for you, I’m currently running the Markbass 102p combo amp, do you think I can ass another 2 10s to it? Like will the head support that ? Thank you

[@malachimoody4381]

So would I be good at full power with an 800W head and a cab that’s 400W at 8 Ohms?

[@firemarshal2629]

As long as your amp runs under 400 watts at 8 olms then yes. You can go over a bit and be ok as long as you’re not gunning it.

[@Thisonegoestoeleven666]

@@firemarshal2629 yep, but if his 400W speaker is getting the full 800W then no, or only less than half volume. Running a risk in that situation.

[@MrOgynist]

You do need to be careful to not run it too hot, but in fact you'll get a better sound at higher volume since the amp is not being stressed and driven to clipping. You are better off overpowering speakers than underpowering. Once you push an amplifier to the top, you start introducing excessive power that is not doing anything except distort. That is bad for for speakers.

[@stevenaustin4591]

quick question - how many watts is enough to gig with? 80w, 100w, 1000w ???

[@kujob6442]

Depends on your gig. 200-500 will cover most bars/small venues. Especially if they are inside. If the venue is bigger, and is maybe outside, 500-1000 is preferred. Pair the amp with a cab that utilizes all the power, or two cabs to utilizes all the power. Though this is not necessary. You could get by with a 100 watt combo amp that just lines out to the PA at the venue. Without a PA though, 500+ watts will prolly be needed to be comfortably loud.

What's the tone advantage of 4x10 over a 15?

[@coltonjames8806]

40 inches of speaker compared to 15

[@matthewprather189]

@@coltonjames8806 That is not how circles work lol

[@nicolas_gulhote]

In terms of tone, the bigger the speaker, the more bass frequencies you'll get, and consequently, less high frequencies. That's why, for more sound definition you'll wanna have several medium size speakers, so you can get a good range of frequencies.

[@nicolas_gulhote]

And for people that want a heavier low sound, they can add a big solo speaker to their gears.

I'm a little confused. So basically I'll never be able to use my heads full potential without two parallel cabs?
