formica Posted February 13, 2003 Share Posted February 13, 2003 Been surfing around for taming room resonance (subwoofer only), and I was wondering which parametric EQ and room measurement tools would work best on a tight budget? Ive looked into the Radio Shack SPL Meter Model 33-2050 as well as the Behringer Feedback Destroyer Model 1124P... Im afraid to go with a 1/3 octave EQ for the lack of flexibility like the Behringer Ultracurve Pro 8024 Digital Equalizer that conveniently has a real-time analyser built in... but am I justified? What have you guys been using? Im just thinking out loud...

Audible Nectar Posted February 13, 2003 Share Posted February 13, 2003 I'm using the BFD as equalization for my subwoofers. It has a "learning curve" to be sure, but once you understand the piece, it's quite a bargain. To learn more about the BFD and how to use it, go here: http://www.snapbug.ws/bfd.htm Quote Link to comment Share on other sites More sharing options...
Doug C Posted February 14, 2003 Share Posted February 14, 2003 I'm using a Rane PE-17 (5-channel) parametric EQ. Purchased this through the SVS website. This is a nice unit but the BFD equipment mentioned sound good (no personal experience with BFD). In my case I'm only equalizing the sub (20-80hz) so 5-channels is a bit of overkill. I use 3-channels to help correct room problems. For set-up I use the trusty Radio Shack SPL meter, the test tone generator in my B&K preamp (provides tones in 2hz increments) and a spreadsheet to record SPL from 20 to 110hz in 2hz increments. First turn sub OFF and record SPL of test tones through the entire range (20-110 hz) for your main speakers. This will give you a good idea of where your mains start to drop-off and where your crossover should be set. You will also see peaks & dips in low frequency output from the mains. Next turn on the sub with mains and play a test tone around the crossover setpoint and set sub phase to achieve highest bass output (this assures proper phase of sub with mains). Next record SPL of test tones through the entire range (20-110 hz)with sub & mains playing and record dB level for each tone. This will give you an Idea of frequency response peaks & valleys and a starting point for setting the EQ. Doug C Quote Link to comment Share on other sites More sharing options...
