So, I've got a Hartke LH500 amp and a Hydrive 112 cab. I'm wondering what my expansion options are cab wise. I know I could add another 112, but what other options do I have? 410? 412? 115? Just curious. At the moment I don't need to expand, but I don't want to wait till the need arises to find out what my options are. Thanks in advance.
Adding anything else than another single-driver cab will be dangerous because the power will not be evenly distributed across the drivers. Your best bet would be to add another Hydrive 112.
There are no other options other than another matching cab that are guaranteed to work. If your cab is an 8ohm model and you like its sound, the most logical thing is to get another. 'Adding' a 4x10 or 4x12 would be silly as either would swallow your little 1x12.
To answer the question in the title of the thread, no a 410 would not be a good option in most cases. The power handling ability of both cabs are very far apart. Most configurations would send equal power to both which could overload the 112 before the 410 breaks a sweat. The most common answer is to get an identical 112. If you want something that is different from your 112 then keep power handling in mind and keep the second cab in the same ballpark in terms of size and/or power handling. Also note that any two different cabs will have different phase response profiles. This means that at certain frequencies one cab will produce sound at a slightly different time than the other. This could cause the earth's destruction, it could be completely undetectable by human ear, or somewhere in-between. Most importantly the potential for a problem in this area will cause a lively discussion if we are lucky. It's been at least a week since I've had popcorn husks stuck in my molars.
I'll use a 112 and a 410 but feed each with a separate channel of a stereo amp so I can match the volumes more easily.
Exactly the reason I made my statement conditional. You have excluded the potential for a power handling problem.
why bother? with a 4x10, why bring out the 1x12 at all? (or is the 1x12 getting placed by someone else as a monitor?)
exactly - I put it on the other side of the drummer and behind him a bit - he likes to have that otherwise i would just bring the 410. and i mistyped - it should be 115.
The LH500 has two speaker outputs. Each at 8 Ohms when run individually, but at 4 Ohms when both are in use. Am I correct in my calculation in thinking at 4 Ohms each cab would receive a max of 250 watts? If that's the case, the 112 still would have 50w headroom as it is a 300w cab. It is also switchable between 4 & 8 Ohms. Haven't done Ohms Law since HS 22 years ago, so I'm rusty.
That's what I was thinking. Another option is my dad has a 412 he doesn't use anymore (he no longer gigs regularly, and when he does gig, he sticks to his Fender Twin). I was considering, in situations where the 112 is inadequate, I could run the 412. I don't really hear about bass players using 412 cabs though, and am wondering why. Also, since the amp has two speaker outlets, how would I drive one cab and still get the full output of the amp? There's no option to switch from 8 to 4 Ohms on the amp, just the two speaker outputs. *EDIT* Sorry Floyd, I read your post about the 412 and it didn't register for some reason. Probably because it's almost 100 Degrees today, and my job isn't climate controlled, so my brain's a little fried today. Plus we had the fire department over today teaching us how to use fire extinguishers by putting out Propane fueled fires, adding more heat to an already sweltering day.
The amp is not switchable power, but that doesn't matter. Your 112 will be lucky to make sound out of 1/2 of it's power rating of 300 watts before it either runs out of mechanical handling ability (can't move back and forth any farther) or hits the limit that is power compression ( can't turn any more power into sound, just more heat). Other than another matching 12, your other option would be to go big and just don't use the two together. Small cab for small stuff, big cab for big stuff. Although a pair of those 12's would do just about anything a single 410 could as far as how loud it could get.
I've had fire training. Actually I work for the gas company and all employees go through it. We are the only place around that does it too so there are always fire fighters taking the classes too. It is pretty specifically geared to NG and propane fires. Not surprisingly we always do way better than the fire department guys when it's time to actually put the fires out. lol Sounds like your dad is a guitar player. You gotta understand that a 412 guitar cab is pretty likely not going to be want you want to use for bass.
Fire training (despite being on arguably the hottest day of the year so far), was very informative and fun. I learned a lot today. My dad is a guitarist. I've seen bassists use guitar amps (Lemmy's "Murder One" Marshall, for example), would a guitar cab really make that much of a difference? How does a Fender 412 guitar cab vary from a bass 412 (obviously Hydrive cabs are different because of the aluminum / paper cones)? When I first started playing bass, I used my dad's Randall RG300 combo until I got my own amp. I've always only bought "bass" amps (combos until I got the Hartke rig) because I thought they must be better suited, because they were bass amps. Is it a difference in the voice coil?
Guitar spkrs are not adequate for bass guitar, forget that plan. Amps are one thing, but spkrs are another thing entirely. You need to use a bass cab, no matter how you go with this. I agree, adding a 2nd identical 112 is the most logical, and guaranteed to work solution you have, unless you go with the 112 by itself, and use a bigger cab as an alternative, by itself. Bass cab, either way.
Cabinet size and speaker design. It takes a different mix of engineering to be able to perform the lower frequencies very well. Different breed-o-cat. That is not to say a bass CAN'T sound good through SOME guitar rigs. It can for some flavors/styles. Usually ones that don't have a lot of bottom in them and benefit from a lot of distorted midrange/treble. But in general, it takes more power and a much different speaker/box design to produce something a majority of people would consider a decent bass cab.
Bass needs to move a lot of air to make the low frequencies loud. Guitar speakers can't handle the jandal and fart out.
