    How to apply an Linkwitz filter to a sub?

    Thanks. But how do I apply a specific filter type [e.g. Linkwitz Riley].

    RdT [Reflection Decay Time] - NOT RT60

    John: Thanks for your response but I guess I'm a bit confused. Someone who knows REW really well told me that I could display RdT directly. Is that not the case?

    RdT [Reflection Decay Time] - NOT RT60

    I did a search on RdT in this website but found nothing. This is the better measurement than RT60 for small rooms [according to many and as stated in the RP22 CEDIA document]. I've been told REW will display it but I can't seem to locate how/where. Thanks in advance.

    How to apply an Linkwitz filter to a sub?

    I still don't understand how to see the effects of applying LR filters nor how to apply them.

    How to apply an Linkwitz filter to a sub?

    I am aware that REW is not an equalizer. I am trying to simulate the results of using an LP/HP filter [specifically LR] to then be able to evaluate things like phase alignment, Group Delay, etc. I can use an iterative approach [various x-over, slope type, etc] using my Trinnov and then measure...

    How to apply an Linkwitz filter to a sub?

    I have a 32" Ascendo sub in the rear of the room and 4 Ascendo 18's in the front. Currently, I run them both full range [the 32 goes out to about 1000Hz]. I want to experiment using a LP on the 32 and HP on the 18s - just out of curiosity.

    Forgetting about the massive necessary physical changes [and attendant costs] to both the front and rear wall to properly place subs to be used in WF, I don't want to give up any of my current headroom. So I would need to spend another $20,000 or more just to use on the rear wall for comparable...

    How to apply an Linkwitz filter to a sub?

    I am trying to apply a HP LR filter to one of my subs, and a bit confused on how to go about it. I found how to "select" LR filters by changing the speaker type in the EQ Tab to driver and then select the filter I want.. So after I do that and then apply a HP filter in the filters tab, is it...

    Perfect. Thank you. I have never known that was even there [nor seen it].
