mark1101 Posted September 5, 2014 Share Posted September 5, 2014 Audyessey........Yuck. I'm not an Audyessey guy. I have it in my HT receiver. Tried it......Don't really care for it........and I would certainly never consider using it for a music system. But that's just me. To each his own. Forge ahead. 1 Quote Link to comment Share on other sites More sharing options...
NBPK402 Posted September 5, 2014 Author Share Posted September 5, 2014 (edited) Audyessey........Yuck. I'm not an Audyessey guy. I have it in my HT receiver. Tried it......Don't really care for it........and I would certainly never consider using it for a music system. But that's just me. To each his own. Forge ahead. I don't have a separate system for music, and another one for video, so I need to use it for both. My main listening is HT, but I am starting to get back into listening to music by itself again. I would like to get the speakers sounding great without Audyessy, and then just let the Denon kick in Audyessy when I want to watch a movie.

mark1101 Posted September 5, 2014 Share Posted September 5, 2014 I like the idea of DSP room effects for HT. But I prefer a more raw (live) sounding system for music. Most of the music I listen to is live music. My HT system is small........Klipsch 500. 1 Quote Link to comment Share on other sites More sharing options...
babadono Posted September 5, 2014 Share Posted September 5, 2014 Thanks, I just ordered the rest of the cables I need to get the bi-amp completed. If the cables are here by Saturday morning I will try this on the weekend. Can't wait to hear all the Yamaha Pro amps on the 1/4 pies, and the "T" chip amps on the JBL horns. I hope it improves the sound even more over the "AA" Networks. This is what I have the MiniDSP set to for starters... Will this be ok... Or should I be crossing over at 500hz? When I look at the specs for the EV DH1a it says "500-20,000 Hz (essentially flat 500-5,000Hz with 6-dB-per-octave roll off to 20,000 Hz, rapid roll off beyond)". I am a neophyte at this but don't the high pass and low pass frequencies need to be the same? At least to start off? Then both the low freqs and high freqs will be down 3 dB at the crossover point and theoretically the acoustic output power sums to equal as in the pass band. 1 Quote Link to comment Share on other sites More sharing options...

Maybe someone that knows will step up and let us know for sure how it should be. Claud told me to put the HiPass at 50hz , and I had been told before the crossover should be at 400-500hz. Maybe the cutoff is not the same as the crossover? Quote Link to comment Share on other sites More sharing options...
shepjk01 Posted September 5, 2014 Share Posted September 5, 2014 No not on the minidsp each channel controls a different driver so say output 1 goes to the woofer it would have a high pass and a low pass. The high pass would be the cutoff of the quarter pie and the low pass the 400hz. Say output 2 goes to your midrange/upper end driver it only needs to use the high pass at 400hz then bypass the low pass filter as its not needed this creates your 400hz crossover. Also on output 1 uncheck the highpass as you want it set at 50hz or the cutoff of the quarter pie. 1 Quote Link to comment Share on other sites More sharing options...

NBPK402 Posted September 5, 2014 Author Share Posted September 5, 2014 (edited) So if I understand correctly... 1: This would be for the Midrange (with a 500hz crossover) ... Or 1b: Would this be the correct way for the Midrange... 2: This would be for the 1/4 pies (with a 500hz crossover and a 50hz hipass)... I think I have them correctly bypassed where needed... Is this correct? 1+2 for the 1/4 pies, and 3+4 for the horns. Edited September 5, 2014 by ellisr63 Quote Link to comment Share on other sites More sharing options...
shepjk01 Posted September 5, 2014 Share Posted September 5, 2014 input 1 goes to output 1&2 so you need to use output 1 for the quarter pie output 2 for the midrange. input 2 goes to outputs 3&4 so output 3 for the other quarter pie and output 4 for the other midrange. Also you have to unclick the bypass button on the quarter pie high pass filter. Notice on your frequency response graph the output of the quarter pie is not dropping at 50hz. 1 Quote Link to comment Share on other sites More sharing options...

shepjk01 Posted September 6, 2014 Share Posted September 6, 2014 Yes for output 1. know set output 2 up as your top end with a 400hz highpass and bypass the lowpass 1 Quote Link to comment Share on other sites More sharing options...

NBPK402 Posted September 6, 2014 Author Share Posted September 6, 2014 Now shouldn't the horn be set to 400 hz so the dip wouldn't be quite as much... Or does it matter? Quote Link to comment Share on other sites More sharing options...
The Dude Posted September 6, 2014 Share Posted September 6, 2014 Here is how I have mine, different bass bin, different horn. Same principle. 1 Quote Link to comment Share on other sites More sharing options...
NBPK402 Posted September 6, 2014 Author Share Posted September 6, 2014 Here is how I have mine, different bass bin, different horn. Same principle. I am confused still... So you are crossing over at 500hz but your bass bin has the Hi Pass bypassed? Shouldn't there be something that shows how low the bass bin goes?

shepjk01 Posted September 6, 2014 Share Posted September 6, 2014 The horn should also be set to 400hz. This allows it to sum flat at the crossover. Quote Link to comment Share on other sites More sharing options...

It just protects the driver. Also most avrs come with a built in high pass for each speaker. Quote Link to comment Share on other sites More sharing options...
mboxler Posted September 6, 2014 Share Posted September 6, 2014 Now shouldn't the horn be set to 400 hz so the dip wouldn't be quite as much... Or does it matter? A Linkwitz-Riley filter is designed to create a -6 db dip at a desired frequency. When the high and low pass signals cross, the voltages will sum, giving you a flat "curve". The 24 dB slope will better protect the mid driver from lower frequencies (a driver killer). Klipsch crossovers are Butterworth filters, and create a -3 dB dip at the desired frequency. When combined, you will get a +3 dB bump. Try them both. That's the beauty of the active crossover...no parts change. 1 Quote Link to comment Share on other sites More sharing options...
