So now I have another question for you guys. The guy with the Hartke 3500 just cut me a deal. The head for $125 if my band gets our scrims (banner things on the sides that some bands use) at his print shop ( which we were going to do anyway). Let's say I have the 350 watt head and it isn't enough power. Can I add a power amp to it and run a bigger cab? I feel like 125 for that head is a pretty sweet deal.
But will the Hartke LH500 keep up with the band? I would prefer to not spend 400 on a head because I'm on a moderately limited budget but I can always put in the extra hours at work if I need to.
Into 8 10's it will. That's what you'll need. Trying to cram tons of power into one small box(4x10) will just blow the box up. It's all about speakers. Lots of them. Or a couple of big ones. Gotta spread out the work.
Even the cheap old Hartke Transporter 410s were rated for 300w into 8 ohms. The Ashdown MAG cabs are 450w into 8 ohms. So with a head rated at 500w into 4 ohms if you're just running an 8 ohm cab you are unlikely to blow anything up.
You would be better off with a 4 ohm cab though to get the most out of your amp.
Those 'ratings' are largely irrelevant.
But that wasn't my point anyway-I was shooting down the bigger amp (1001RB) into a 410 idea.
Reading comprehension ?
Who said a sing;e 6" will give the punch of a 8X10 ?
What was stated that thew amount of mids and highs necessary to provide a balance with a single 15 cab in a bi-amp situation can be provided by a 6" mid driver.
When bi-amping with a 1X15 and a 4X10, the 4X10 is a giant paperweight for the work it performs.
TBH I think if you need more than 500w in your backline you're doing backline wrong.
Speakers are not flat circles, they are closer to being cones.
Sd for two common 10" bass drivers I looked up: 700cm2
Sd for a 15 of the same family: 856cm2
Granted, the percentage difference ended up about the same, but better folks know the real calculation.
In surface area the 4x10 exceeds the 1x15 by far. But that doesn't matter, displacement does. For that, the 15 is about the same as 3 of the 10s... so neither is a good match on those grounds. Both tie with a "fail".
Power handling of two of the 10s is the same as the single 15. Which of course makes the 4x10 double that. Cut both in half to get closer to real (excursion) limits, but still... the 2x10 wins this round.
It also is closer in sensitivity (only about 1db higher than the 115), so that's two wins.
So using real numbers a 2x10 was a better match for a 1x15 than a 4x10. But it still isn't a match.
Whatever works for you. I have to say though, time and time again, people who know better than nearly all of us have laid it out pretty plainly. A 115 and 410 together is one of the worst combinations possible. Your mids end up getting hacked to shreds. Maybe your hacked up mids were percieved in the room as a big scoop. I don't know.Everyone listening liked the mixed combination of a single fifteen with four tens the best
When I was researching the Hartke heads I saw lots of setups with a 4x10 and a 1x15 so I assumed it was a good setup for those heads.
What "real" calculation ? You have not added any information to perform a real calculation.
This page has some very good info about air displacement though. The fact is it doesn't matter very much. The actual performance as measure by sensitivity is a much more important value.
On what basis are you making this generalization? Usually the displacement of a 15 is larger than a 10 because the surrounds are wider and the voice coil is deeper so the excursion is farther but I have no real numbers for the cabinets I mentioned and you have not shown any either.
No, it does NOT. You can not infer excursion from power handling. Some speakers reach the thermal limit of the voice coil before the excursion limit of the cone and some are exactly the opposite.
No, it is NOT. There are extremely few people in the entire world who can discern a 1dB difference in sensitivity and it is highly unlikely anyone would be concerned by it if they could. That is essentially a tie.
I disagree. You have shown NO real numbers that prove anything.
First, Hartke does not make a HyDrive-series 2x10 cabinet. Second, I think the two cabinets listed ARE a very close match and the 1dB sensitivity difference PROVES it. It is highly likely that Hartke designed them so that they would, in fact, BE a close match since those two are the combination that so many of their endorsers use.
As for me personally, it is a combination I use because I think they sound good together.
