Frequency dilema

Turtle · 08-01-2009, 05:57 AM

Can somebody tell me the frequency range of Marshall MBC410 and MBC115 cabinets? And what brand of speakers are in these cabinets?

frequency range? sure you don't mean impedance? what exactly are you trying to figure out?

I'm going to go by what you asked. This is a bass guitar cab. It has a 4 ohm rating. Besides the (4) 10's, it has a built in horn. The horn can be switched on or off. Based on my years of speaker experience, I would say the frequency response would be around 52Hz to 4.5KHz without the horn and probably up to 12KHz with the horn. It's probably got a phenolic diaphram in the horn. These are not know for super highs, but they are sturdy. Afterall, it's a bass rig. How much high freq do you need?

The MBC115 is a single 15-inch bass speaker with a horn. This cab will probably handle a low E @ 42Hz without much problem. Without the horn, I would say the top end on the 15 to be somewhere around 3Khz. Again, it has the horn and this will boost the highs.

If you plan on using both of these together, make sure that your amp will run a 2 ohm load. I have a massive Peavey bass amp that puts out 800 watts into 2 ohms. You have to be real careful with that kind of power. Make sure all your power cords are monster style, preferably 12 gauge wire.

Do you have these cabinets? Were you planning on using them for bass? I'm just curious. You can Google or Dogpile and find most of the info you are looking for. None of the sites I went to listed the frequency response. I thought that was sort of odd. Most bass players want to at least know how low the cab will go. JMO, I wouldn't use this rig with a five string. I don't think there is enough bottom end. The 15-inch is in a moderate size cab. To get a low A happening, you need a larger cab with a high tech 15 or 18-inch speaker. I can't stand a bass player who plays a five string out of a (4) 10 cab. You might as well remove the low string.

Well, I hope this helps you out. If I come across the exact frequency response for these cabs, I will post it back here.

Well here is a "pro" who did a review on it. He uses active pups on a Five String and he says it works perfectly. (What do I know?

)

Well the only major problem is that these cabs are made out of MDF and that means they weigh a ton. They're perfect for a permanent backline, but not so good gigging as that MDF can break down.

Thanks Marty for the info: I tried to contact marshall themselves but as of yet no reply but thats what I was looking for is the frequency range of the cabinet. Most manufactures tell you what range their speakers are at but not marshall, I guess you either buy their product or not, ie ampeg 32-4.5khz, behringer 34-6khz etc. must be top secret information at marshall. And yes I so far have bought the mbc410 but haven't tried it yet going into a circ. 1974 year I don't really know what it is except that it's the same as the super lead, 100 watt super bass head (1959) but devised a box to convert 2- 4ohm loads to 8 ohms and vice versa to achieve the 4/8/16 ohm load. Thinkin about the VBC 412 next and hopefully will find maybe a 4-15 cab. but marshall won't turn loose of their specs. I also don't really want a 5 string bass I just want to know if the cabinets could go low enough "if" I ever wanted them to for any reason.

a box to turn two 4ohm loads into 8ohms??????????????
how does that work considering two 4ohm loads together yield 2ohms???
is this something you built yourself?

Just a little secret about speaker ratings. The Ampeg and the Behringer ratings are actually + or - 6dB. So even though they say the cab goes down to 32 or 34 Hz, it is actually rolled off by 6dB! This is a common practice and it makes the "numbers" look good. I've only seen a few cabs that could do a low A (28Hz) at 3dB down. The boxes on these cabs are six to eight cubic feet and ported. Again, this is a permanent style bass cab. Not practical to move and gig with. So if you get a cab that says 32 or 34Hz for the bottom end, in reality it is flat down to about 45Hz.

Now about this load device you have. Did you make it using non-inductive power resistors?

The box is just 3 female jacks, 2 wired in series going to the speakers , + going to spkr jack A and to the amp jack, - off spkr jack A to spkr jack B +, - off spkr jack B going back to amp jack -, use a noncondutive box. I got mine at home depot a plastic 4 by 4 and put one set on one side and on the oposite side and labled them C and D. The other box I made turns 2-8 ohm loads to 4 ohms, I labled them A and B that way I won't use the wrong box for whatever. Also Marshall as of yet hasn't responded to my e-mail nor do I think they will! Two companys that don't give out the frequency ratings of their products are Marshall and Hiwatt, you either buy it or not!

Also if somebody can tell me the frequency range of the VBC-412 along with the MBC-410 and MBC-115?

Thanks for your hard work, hope more and more people come here to sharing their valuable business experience. Let improve business skills together. Thanks your suggestion. Just for my need. I've been listening to this album a bunch recently. Really great. I'll assume this is directed to me since it's right under my post. stainless steel pipe
