Got a MT121 Loaded with PD123er 400w driver BM-D750 100w Comp Tamp dose 8ohm 350w per channel 4ohm 500w per channel How do I choose between ohm settings or dose it automatically read what power needs to be sent, or do I do tbis on my xover Aslo would this MT run at 4ohm Got a 1200w to run drivers and 800w for comps to power 2 MTs at 8ohm . but Wanna see If I can run 1 top of the 800w amp

the mt121 needs to be looked at as 2 separate speakers in one box. they both need their own amp channel and crossover channel.
an amp that will do 500w into a 4 ohm load will do about 300w probably into an 8 ohm load. nothing to switch, that's just how power works. |

Hi, you've got 3 posts up. 2 titled MT121 and 1 titled scoops. Between the 3 posts the advice you're seeking is a bit garbled and could have done with being all in one place.
My understanding of the situation is that you have a 800 watt t amp and a 1200 watt tamp to power the MT121s. You also have a BS1200 and 3 scoops. You have not indicated what amplifier you have to drive these. Assuming you're going to run these in a mono stack and also assuming that you have a fairly hefty (power wise) 2 ohm ready amp then you can put the 3 scoops on one side (loading will be 2.66 ohms) and the BS1200 on the other (loading will be 4 ohms). So essentially you have a 4 way set up. I am not familiar with Vector crossovers but assume it's capable of running the amplifiers for such a set up. I'm a bit confused as to why you're asking about running one MT121 off the tamp 800 but the short answer is yes, powering each unit from different channels.

Thanks for the help!
I’m new at all this haha I’m looking up getting upgrading to 6 way crossover Channel 1 - scoop 2 - scoops on a link 3 - bs1200 4 - MT driver 5 - MT comp Looking at getting a JAM Q10 to run all 3 scoops and Bs1200 Only asking about running the Mt with the 800w as wanted to play around with 1 scoop and 1 MT on top, as only got the 2 amps at the moment.

Before I advise you more can you let me know if the Vector crossover is capable of at least 4 way deployment? If so we can get you up and running now.
As for what you've stated as your near future plans you can still run everything you've listed from a 4 way crossover. What you have listed as "scoops on a link" does not need to take up a crossover channel even if your going to use another amp channel. You don't need a 4 channel amp either. A better quality 2 channel amp that is 2 ohm ready would in my view be a better investment. As in my previous reply you can run all 3 scoops on one channel at 2,67 ohms and the BS1200 on the other channel at 4 ohms. You might also consider getting a 2nd hand heavyweight amp on bass duty. For £700 (the cost of a Q10) there are some pretty good offerings out there. |
