Tri amp - which way to go?

[Chunga72]

Hi all

I am currently building a tri amp system which is a mtmww. I have a passive MTM crossover sorted and it sounds good.

Do you think i should drive the MTM with one channel and existing passive and then drive each woofer with its own active channel? or should i ditch the passive and drive 1 channel for tweeter, 1 for mid and 1 for bass?

Cheers Chris

When the mid is of high enough sensitivity to be near the tweeter you can run them from the same amp and still enjoy some of the freedom of amp choice, not requiring large amounts of power.

Thanks allen b for your help,

I will build the passive into the speakers and put triamp and passive inputs on the back of the speakers.

Cheers Chris

I recently converted from passive LR2 XO driven by a diy GM70 SE amp into my 3 way speaker system to fully active with a dedicated amplifier channel for each driver. I thought it was pretty good passive, but much better now with fully active set up driven by diy LR4 3 way line level XO into 3 channels of diy SE power amps. (The system is a high efficiency set up with horns on mids and highs) Rather a lot of electronics as you might guess.

Was definitely worth it IMO.

Sounds good, I am really looking forward to the tweaking process with the active crossover. Was thinking I would get the new mini dsp box that does triamping and has a big volume knob on the front so my wife can crank it up ( well down actually).

My wife often asks me to turn the volume down and I'm in the man cave which is located under the living room. She and our pet rabbits have variable attitudes wrt what I am listening to at any given time.. LOL

Quite a lot of tweaking involved so far and I am currently working on the design of a parametric room EQ for the system.

I thought I would use the same xo points as in the old system and ended up with everything different.

A mini-dsp should be very flexible.
