Will a svt 18e support a 810 cab?

[fourstringburn]

Thanks! As an engineer, I am familiar with physics. Sound waves do not need any certain distance to "develop." There is no such thing. But the myth continues to exist, and so I just accept that fact!

Myth??? facts???

Well, I tried to help you understand, but feel free to believe what you wish, good sir!

Here's a fun test for ya: I googled "40hz tone" and found the link below. Play it on your computer speakers. If you can't hear anything until you are at least 28 feet away from your speakers, then you are correct about needing 28 feet for the 40hz sound wave to develop. But if you can hear it any closer than that, then you will have learned.

Curious though, as an engineer, you can't explain your headphone phenomenon.

I never ONCE said you wouldn't ever hear it. It's the full wavelength I'm REFERRING to.

YOU SAY YOU ARE AN ENGINEER???

I can see this will go off topic and a become troll fest so I'll cut it off from my part right here.

Have a good night and wish you many good gigs in the future!

I weigh a bit more than the average 810, so if you want me to go around sitting on things, just let me know and I can report back.

I don’t think I’ve met a bass cab that I couldn’t sit on - including my Eden Nemesis stuff, which isn’t exactly wood construction.

I used to play an SWR 8x8 - so I understand the idea of lifting it to actual ear level. I never lifted it but did need to stand a bit away from it to really hear it. Too close and my ears weren’t getting the full effect.

I used a 15 watt solid state guitar amp in one band (mic’d for gigs). I would place it on a 4x12 cab just to elevate it. I had the option to run it through the 4x12 cab but never needed the extra volume. We practiced loud. It was an 8 piece rock band. Everyone heard me fine and just assumed I was playing through the 4x12.

When I would play my bass stack, often times I would just run through the top cab, as the distance I was standing from the rig (close), I couldn’t hear the difference when I connected the bottom cab.

I would never want a speaker at ear level at any volume required playing in a band situation.
I’ve played 810s for years, when picking a new cab (and deciding on the Fender neo series) I was torn between the 610 (more sensible size) an 810 (closer to ear level).

Went with the 610- turns out a great cab fills the whole room with great tone I can hear standing anywhere (even behind it!).

That's OK in religion and politics, but not in science. Lows will be much lower in volume close to the speakers when the reflected waves off boundaries mix with the original wave out of phase, resulting in a null zone. When you move further away the distance relationships between the speaker, the boundaries and the listener change, and there is no null. The myth of wave propagation was created by those who experienced the phenomena of the lows being heard as louder further away from the speaker than up close who lacked the knowledge of how sound waves work to explain it correctly, so they came up with an alternate incorrect explanation. You can believe what you want to, but a hundred plus years of science isn't on your side.

 

[armyadarkness]

Well, compare that 810 cab to how much *YOU* weigh. Then stand or sit on the 18e cab and see how well it handles your weight. If it holds you, then the 18e should hold the 810 cab.

You are wise in the ways of science. It's really a question of weight ratio's.

Having no training or pro experience on the subject, I could see that a sound wave could change as it traveled, but then all sounds emanating from that same source would respectively change as well.

When you're at a baseball game, the sound of the ball hitting the bat isn't changing, just when you here it. Or no?

Well to the OP, my two 4x10's are on their side, under a table, facing sideways, and professionals say that it's the best bass tone that they've ever heard. As for cab strength... Any bass cab that I've ever seen, even a budget Peavey, would support the weight of a Chevy V8.

Pursue what makes you happy. Leave others to to live in their world of mindless gossip and speculation... I've had a Harley Davidson Road King on top of bass cabs.

Lol, I was just reminded of that old saying... 'those that cant do, teach'.

Will a Ampeg SVT - 18E cab support a SVT-810HE cab? My guitarist freind says no. I say yes.

My 1990's-era SVT-18e is the same depth as my 1972 flatback Fridge.

My SVT-18e is quite a bit narrower, but it's wider than my Fridge when placed on it's side...

My SVT-18e is strongly built from fairly thick plywood, not OSB or chipboard.

So I'd say your guitarist was wrong, & you were right...

Wavelengths not withstanding, we need to be know more about the entire system.

1) What head are you using?

2) What is the ohm rating of each cab?



Here's the other "myth" you need to understand. And 18" speaker is just a speaker. Just being larger alone doesn't necessarily mean it will handle a ton more power. (Some can. But it's because they are designed that way, not because of size.) Someone more qualifies than I am will have to speak to the exact specs of that particular 18" speaker.

So, if your cabs are both 4 ohm, that one 18" driver is getting 8 times more juice than any 10" driver (because the power is divided evenly among the tens in that cab).

Forget watt ratings. A 300W SVT will blow the ever loving crap out of every driver in both cabs even though the total wattage ratings of the cabs combined could be well over 1,000 Watts.

Meaning..... if you try to get the volume up on the fridge, you'll likely murder the 18.

If it were me, I would develop another kind of stand for the fridge. Or if you take the 18, use it for looks alone and leave it unplugged.

Short version: An 18" speaker isn't always "more tougher-er" than a 10 speaker. Keep that in mind as you move forward.

 

[voided3]

I'm fairly certain the OP just wants to physically set his 8x10 on top of the 1x18 cabinet, not actually hook up the 1x18 cabinet. The physics of phase cancellation/audio transmission and mixed driver/impedance issues won't apply if the 1x18 is used as an inanimate object.

Oh no! We're not going down the American vs. African Swallow path again, are we?

No need. A 5lb bird cannot carry a 10lb coconut.

I posted a pic a few weeks back of some cabs that I was pulling out of storage. TWO Markbass 410 HR's and TWO Markbass 4x8 HR's. I was really surprised that the Watt and OHM specs were identical...

Hard to believe that the little 24"x 24" 4x8's could handle the same 800 watts as the giant 4x10's

I got that impression too, but while phase etc isn't a problem when you put a speaker that's not being used next to one that is the unused speaker becomes a bass trap, absorbing energy from the speaker that's in use.

Power ratings only say how much juice they'll take before the voice coils burn out. How much acoustic output they're capable of is a different story, and is only vaguely related to the thermal limit.

 

[okcrum]

Try standing further away or move the cab further.

Bass frequencies travel further to fully develop than high frequencies.

No, they do not. They emerge from the cabinet fully formed.

If they took some distance to form, you would not be able to hear any lows with your head next to the cab, and headphones would not work.

All this was explained to you in the other thread.

I guess all the speaker manufacturers who measure sensitivity at 1 meter distance have got it wrong in your book.

LOL! Well played Army.....well played!

 

[agedhorse]

Sound that your ears hear are actually pressure waves, the pressure generated from each point on the wave as it propagates by is what causes the ear drum to move and for us to hear.

It's another absurd myth that lower frequencies need room to grow and form to be heard. Otherwise, ear buds wouldn't have any low frequency response.
