Why is mixing cab sizes a bad idea?

Honsetly that makes no sense.
Biamping does not mean you have two amplifiers pushing power to two different cabs.
It rather means that you power one cab low passed with one amplifier and a second cab high passed with another amplifier.

Furthermore it makes no sense that you get a good "distorted" sound with your system while the clean sound sucks.
May be you are missing "loudness" with your clean sound? 1x12 and 1x8 isn't lots of cone surface to get a "loud" clean sound versus distorted sound stuff.

Lol. It’s a classic case of using words that one does not know the meaning of, trying to explain something that one does not understand.
 
I've heard that you shouldn't mix cabs, but why is this?

I would have figured that using a 1x15 and a 2x10 together would give you a warm low end from the 15 and a tight top end from the 10s, but I guess this isn't the case.

So 7 pages, which I haven't read, sorry, and you probably know the answer to your questions.

My 2p. . . some cabs don't work well together and some do. I ran Mesa 210 and 115 EV cabs together and separately for 8 years and that combination sounded great. Then there is the misconception that 15's go lower or have more bass than 10's. This hasn't been a thing for 25 years or more and the sound of a cab totally depends on the driver and cab designs not the size of the driver.

If I implied in any way that you are stupid, for that I apologize.

I'm thinking perhaps your geographic area may have been populated by slightly more sophisticated players than most. Around my area, all of the "conventional wisdoms" applied.

Stick a 15 under tens to round out your tone.

Underpowering speakers blows them easier than overpowering them.

The list goes on.

As a teenager I bought into many of them myself.

Anyway, before I start to ramble...

Carry on. I hope I didn't come across as argumentative or demeaning.

Not even close. No, I was not referring to you, just what has been a constant here for going on twenty years.
:D

When you drill down on a lot of what passes for conventional wisdom, they're oversimplifications with lots of exceptions. I just participated in a mixing cabs thread that didn't instantly turn confrontational so maybe there's hope.
;)

Informing others of potential pitfalls is not the problem... telling people to flat out not try or do things that have clearly worked for "outliers" is. I'd only be playing a fretless with flats through amplification they liked if I believed the experts.

I hate to be one of those not read all pages guys but.......I haven’t!

But for my pennies worth, if a Bi-amp dirty type sound is what you really want, then this can be achieved with a single amp and a single good cab of choice.

Look at the Tech21 dUg Ultrabass 1000, Wounded Paw, EBS Fafner, Tech21 Landmark 300/600.

Pedal wise you have things like the Tech21 DP3X, wounded Paw do a pedal, Darkglass X7, or use the KMA Audio Machines The Tyler frequency splitter/Double FX loop pedal.

Loads of options to recreate the similar sound in a smaller package
 
Well, I don't "clown" anyone here...it just didn't sound that great to my ears 30 years ago and that's my opinion of my old rig.
If I wanted BIG low end from that Hartke 115 to match what the 410 was doing (closer to my ears on top of the 115) I had to Bi-Amp it so I could lower the volume of the 410 and then the 115 was almost jumping right out of the cab without producing much in the way of a big low tone when I got to a volume where I could hear it... I was more worried that it was going to fry.
I sold the cabs..
I was stupid enough to try another rig like that a few years later... I had a SWR SM-400 running a SWR 212 and a SWR 118. It was a bit better in that the 212's had better tone than the Hartke 410's did but once again, getting the 118 cab to deliver decent bottom end was a problem. I had to drive the amp way too hard.
I sold all of that stuff too.
Then.. I decided to go stereo using two amps and two cabs and wired a couple of my Jazz Basses for Fend-O-Sound, just like my Rickenbackers..... that took care of the problems of balancing out my entire tonal spectrum. I prefer having separate control of each pickup rather than mashing them into one signal and then through a bi-amped or even a one channel rig. That would strangle the tone of my basses for sure.
There is a world of difference in a true stereo rig using both pickups (if you have a two pickup bass) compared to your standard mono, one signal.
At least in my world..

You may have noticed I did not say you did.
:)

I know lots of bassists who got great results from the Guild/Hartke setup back then. It wasn't all FOH. It worked well for Daryl's style of play, better than the other offerings of the day. IME it sounded like a nice biamp rig (blending two different sounds) without the need to biamp.
 
I know that the 410+115 cab combination is the most hated combination on TB forum

Deltalite II 2510 410 cab (yellow) versus Deltalite II 2515 115 cab (white)
View attachment 3335153

cone excursion for the 410 cab 500 watts input power
View attachment 3335158


cone excursion for the 115 cab 250 watts input power
View attachment 3335164

In total this means that the 410 cab would handle mechanical wise "more power" but the benefit of headroom versus the 115 cab was only +3dB

That hatred is a great example of mind think. And loads of people believe that that stack is bad based on principle alone. The day when I'd rely on the ears of others (or worse, thoughts) for my audio decisions would be a sad one.

Results are what matter. Who cares how you get great results? BTW great is in the ear of the beholder. And if you as a player hear great...
:D
True, but then so did 5 other bass players who used my rig at an outdoor event with no FOH support. My band ws the host and we back lined out gear. They had the option to use their own or use mine. My band opened, and every bass player opted to use mine. It could have been because it sounded that good or because they were too lazy to load in their own gear. :)

View attachment 3334656 It’s like agedhorse said, it depends on how they are engineered brand wise and construction wise, I believe if you stick to the same brand and model series mixing and matching isn’t a problem, in fact they are made to work and compliment each other like this!!
Respectfully it is not that simple no matter what company's gear you are using.

The main problem with a lot of the ''I love my 410 over 115, mixing can be great'' crowd is they don't realize the insignificance of the 115 out front, their satisfaction being derived from a full body shot of 410. So long as they don't blow their 115 all is well enough.

For the Deltalite II modelling I did above this would mean that the 2510 drivers were at least damaged if the 2515 driver was blown up due to abuse.
As you can notice with the plots above the power handling headroom (and SPL headroom) for the 410 just to not damage anything is quite small

That assumes the 15 will be insignificant compared to the 410. The problem with that assumption should be obvious. A lot of them aren't.

I have a small Yorkville 115 cab that I loaded with a Mesa EVM Black Shadow driver. I have yet to find any cab efficient enough to come close to hanging with it on a one channel rig. The only way to use it for me was with two channels where it got less power than the second cab.
 
There are plenty of cases of ''why did my 15 blow?'' as well.
May be but, they never did ask any question if the 10" drivers might be simulatneously damaged.
The tricky thing with (already) damaged drivers is the fact that the sound might be still "good" to the ears.
Even for trained ears its sometimes hard to detect a damaged driver but, once a driver was damaged the total fail is (almost always) certainly.

I think TB forum is full of threats where players ask questions for a good substitude of (any else) blown 10" drivers
 
I've heard that you shouldn't mix cabs, but why is this?

I would have figured that using a 1x15 and a 2x10 together would give you a warm low end from the 15 and a tight top end from the 10s, but I guess this isn't the case.

Cause in reality aside from few exceptions. A 15" speaker and 10" speaker pretty much cover the same bandwidth and Extend to 3 to 4k.

The 10s don't offer any mystical magical more high-end than a good well designed 15"

Likewise the frequency response of every speaker is slightly different and can cause wierd response peaks or dips.

Pretty much no benefit.

Like a well tuned balanced engine. All equal well balanced pistons driving away equally to a crank

Balanced well tuned and matched speakers all driving away equally to air.

Make for a much more predictable and consistent sound. Not wasting power creating a unpredictable response full of peaks and valleys.
 
"If it sounds good, it is good."
Mixing cabs may, or, may not sound good.
Might sound good to you, and same combo sound bad to someone else; which is fine...sounds good is pretty subjective.
The main "real concern" is the power handling mis-match between the mixed cabs, and, if that's enough to be significant and problematic.
If you find mixing cabs works for you, and you like it: have at it man. Bueno.
