I have Type R components up front and Type S coaxials in the rear. What would be a good high pass x-over point for them? They are powered by an Alpine MRV-F340. 55X4 rms. Thanks in advance for any input.

 

What slope is your crossover?

 

12db/octave.

 

I assume the F&R crossover points are independant?
With your variable 30-400Hz HP x-over, I'd start around 125Hz and play with it +/- until you're happy.
With coaxes out back, they will drag your soundstage back so the rear setting will not be as critical as the front IMO.

 

Yes they are independant. Ok I will try about 100-125hz on the front. Are you saying just leave the back full range then? Wouldn't that be worse for soundstage as more mid would be heard from the back.

 

Start at the same point for the rears too. You can probably set it at 100-125 and just forget about it. If they pop on deeper stuff, move the point up a bit. If you want a little more midbass, try lowering the freq until they can't handle it and then up it a little.

 

Gotcha! I was kinda looking for dead set answers but I guess it's whatever sounds good and works. Thanks for the replies.

 

It's impossible to give a dead set answer that will also give the best sound. I mean, you could cross them at 125hz and just forget about it, but I personally would listen to it, lowering the point a little at a time until they fart and then move it up a bit. Then you know they are playing as low as possible which is generally considered desirable.

 

Makes sense to me.

 

No, I wouldn't ever leave the back full range, or any small speaker to be exact. Do you have a sub? Guessing so, and I find that depending on how many you have and what size, the sub just takes over. I like to have more efficiency coming from the higher bass to vocals and up. A little 5 1/2 to 6 1/2's will put out little bass compared to 8's, 10's or 12's. Only case is if you have a 3 way setup, then its a different story
