    Hi guys, i am a newbie in HT.
    Recently, i brought a marantz 4500 and MS premiere plus sat/sub
    for my bedroom which measure 3.8 meters by 2.7 meters.
    After setting up the system, i am now very confuse of the sub setting.
    I have read through the forum.

    1)There are experts who said set the cross freq at 100mhz on the AV-R and max the sub cross freq.

    2) or Set to 100mhz on the AV-R and turn the cross freq on the sub at 10o'clock (which is about 80 mhz)

    lastly, anybody who own the MS 309w set their notch filter to on?
    currently, i have set that to off cos i find it quite confusing to set it.
    does it affect the performance?

    Really appreciate if you guys can give me some advise.
    Thanks in advance :)

    If the amp has an adjustable crossover, you might as well use that- where you send it rather depends on your speakers. Having done so you might as well put the sub crossover to maximum.

    I do indeed use the notch filter on my 909 but suspect that you don't have a test disc so you will need to send me an address.

    Thanks Thanks, i am so gald that you have replied.
    I'm from Singapore. It did came with the CD when the sub was delivered.
    Do you think i should set my amp crossover to 80, 100 or 120?
    and should i leave my sub volume to 12'o clock and fine tune the rest on my amp or otherwise?

    thanks thanks, really appreciate your advise. :clap:

    Good day!

    I would say set the sub crossover at 120 and see if you like the sound. To really be able to use the notch filter you will need a Sound preasure meter to use with the test disk as detailed in tht back of the manual. Then find out if you have any nasty spikes int he bass and set the notch filter for that number and it flattens it out. :smashin:
    I have a spike in my room about 56htz which the notch filter on my old 309 sorted out. I may have to buy a BFD in the future for my SVS.

    I'd suggest bypassing the subwoofers crossover and setting the amps crossover to 100Hz.

    Similarly, I always try and leave the amplifiers subwoofer volume at zero and adjust the sub itself.
