Configuring a 50.4 for mids / tweets

[freat 0]

Hi,

I just ordered a 50x4 and will be using this to drive my mids and tweets separately.

It looks like to me the best way to do this is:

- connect mids to 1/2, tweets to 3/4

- for channels 1/2, set it to HPF @3000 or similar

- for channels 34, set it to LPF @3000

Then, for 1/2, set the subsonic filter the the crossover point with my sub.

Is this a legit use of the subsonic filter? What is the x-over slope on the subsonic? My other amp is a 125.2 bridged driving a soundsplinter rli-8.

Cheers!

For your mids, you would want to use your HPF and LPF for the range that your mids will be playing. If you are only using the 50.4 for mids and tweets, you would not need the subsonic filter as there is no sub attached.

You aren't understanding what he's saying. The subsonic filter on the amp can be used as a highpass filter for the mids at 80 hz, or whatever. The subsonic on the 50.4 goes up to 500 hz, and I'm guessing is 12 db/octave.

To the OP, you have the crossovers switched around. You'd want to highpass the tweeters at 3k and lowpass the mids at 3k.

I understand that. I'm just wondering why you would use the subsonic Filter as a High Pass Filter when it has a High Pass Filter already?

I would use the subsonic because you have to choose with a switch, hpf, full, lpf. Can't do both on the same channel. But you can use the subsonic as it is separate.

Check out page 5 of this manual and look at the drawing of the 50.4. You'll see what I mean.

Because you want to bandpass the mid. The mid needs a highpass at 80 hz or so and a lowpass at 3000 hz or so. You only use the actual highpass filter for the tweeters on channels 3 & 4. And as freat said, you can't use both highpass and lowpass on the same set of channels at the same time.

DOH, all is clear now. I was thinking you could use both HPF and LPF as a bandpass filter, but yea, you need to use the SSF (reading > Me). My 100.4's are the same way, it just didn't occur to me since I'm using the crossovers on my H701.

Also, this is just a temporary arrangement. I'm rebuilding my audio processing computer which will be doing all the crossovers anyways. I just want to buy the right components to start with, plus I want to be able to pull the computer out whenever I want to work on it and still be able to listen to my tunes.

That will work, not so sure on the 3kHz point but you can use your ears to decide. I would also expect some underlap to clean things up a bit.

Listen to the mid and the tweet separately and see how high/low they can play and then make your crossover decisions.

Yes, the subsonic was designed to be able to high pass the midrange to create a band-pass filter.

I use mine in the Jeep this way

Hi! i am expecting a 100.4 and im going to use it active, so please enlighten me.

set channel 1/2 to HP x10 and HP it at say 5000hz, set channels 3/4 to lo pass x10 and say at 5000hz and set the SS of channels 3/4 to around say 80hz to band pass the mids as per your post, the SS knob is functioning independently regardless of whether the channels are used in HP/LP?

thanks
