I recently purchased a Behringer Feedback Destroyer (BFD) to EQ my SVS 20-39 PC+ sub (which I have had for over a year now). I thoroughly enjoy the SVS but would like to get the most performance from it that I can. Using my Radio Shack meter and Stryke Bass Zone audio CD, I have found that I have some rough spots in my 20 – 200 Hz low end that needs smoothing out (HOW DO I ATTACH A FILE TO A POST?) . I was considering a graphic EQ such as the ART or Rane that SVS has on their web site, but after some research, I’ve found that the BFD provides a lot of flexibility, and at a great price. I plan on adding a second SVS 20-39 PC+ and it will likely not be co-located with the first one and so the 2 channels that the BFD has an added benefit.
I want to thank Sonnie Parker for his DUMMIES GUIDE, which helped me get over the BFD intimidation factor (this guide was a key decision maker in deciding to go with the BFD rather than a graphic EQ). Also the info notes from Ken Bruce, and all the useful posts from Wayne Pflughaupt. Finally, the Excel Spreadsheet from Chris Tsutsui makes reviewing my frequency response a snap, and is extremely helpful in targeting the problem areas, and seeing what affect the BFD has when making adjustments.
The family room, where our home theater is located, is on the first floor of our 2-story house (concrete slab foundation). The family room is about 24 feet wide by 13 feet deep by 8 feet high (about 2500 cubic feet) with wood paneling. The right wall (13 feet) is a brick wall with a fireplace in the middle; all along the wall is a concrete slate ledge extending out about 20 inches and about the same height off the floor. It is in the right FRONT corner that my SVS sub is located (just to the right of my AV rack upon which the right speaker (Polk Lsi9) sits. I may have room to add the second sub here, or at the right REAR corner. I have no other corners to locate these subs. The left wall has doors, at each corner, leading to other rooms. The only opening in the family room is a 3 foot wide stair case leading to the upper floor (its near the left, along the front 22 foot wide wall). So, my sub is NOT on the floor, but rather, about one and a half feet off the floor and sitting on a concrete/slate ledge. I hope this helps with how my set up is oriented.
I’ve had previously calibrated my sub about 3 db hot relative to my mains (I use AVIA for all my HT calibrations). Using the Stryke BassZone audio CD, I took measurements from 20 Hz to 200 Hz (I would like to attach my results, which has raw and adjusted values). My Sony ES 30 receiver is about 4 years old now (bought it when I first got into HT) and it has a fixed crossover – which is high (about 100 or 120 Hz as far as I can tell). I’ve never found any documentation indicating what the exact x-over is for this receiver (anybody know)? I run my speakers set to SMALL and let the sub handle the low end. This is how my system was set up when I took these measurements.
So, I hope you can help me out. I’m looking forward to taking advantage of all the expertise here on this forum and to improving my sub’s performance. Thanks to all. The BFD is an inexpensive, versatile, and worthy investment. JEFF
