Hey i was just wondering if the high pass filter on the amp should be set even if using external passive x-overs. Arent they doing in effect the same thing and the x-over is only cutting out even more of the already filtered frequency? Or am i way off here?

 

So you're saying you have a seperate crossover and you're asking if you should also use the crossover on your amp?

In most cases ...no. If you do this, it will add the slopes together, but it is hard to be sure that your cutoff is exactly at the same frequency.

How steep is the crossover slope on your crossover? On your amp?

I guess every install and system is different. You may want to play around for a while and see what different settings sound like, but at the end of the day I'd prolly just keep it simple and just use the crossover.

 

It would help if we knew exactly what you doing.

You're asking about using the amp's HP xover, which might imply that you're running a component set (mids & tweets). By using the passive xover that came with the set, you're dividing the proper frequencies to the speakers - HP for the tweets and LP for the mids. However, if you set the amp's HP xover you can limit the lower frequencies from your mids, which is a common practice. So I guess what I'm trying to say, in a "it's 5am and I'm really tired" way is that my answer might change depending on your particular use.

yea Im running a component set just wondering cause the midbass sounds a little too lean

 

Use just one crossover, try setting it a little lower.

Are your doors well dampened and sealed? How much power do you have going on to them? Is the phasing correct?

 

so i just went and decided to mess with the settings on the amp, turned the filter off and reset the gain properly, and i got a much better sound, thanks for the replies guys

 

the 2 crossovers function differently....the passive crossover will divide up the frequencies the amp gives it...if u turn off ur amps crossover then u are sending all the frequencies to the passive crossover...the passive crossover will send even sub bass frequencies to the mid which isnt good..id use the amps high pass with the passive crossover...i dont want my mids getting 20-60Hz

 

Like posted above they do different things...Typically your amp should be set 80Hz or slightly above If it is variable.

I have focal 6.5s in the front with a crossover and with out the high pass on the amp the lows would still make their way through. So i have it set so the high pass cuts out the deep bass for the fronts and my sub will fill the low tones like from maybe 50hz down. The x overs that come with the speakers are more for just splitting it for the tweeters.
