Best subwoffer crossover with room correction
I have a Rogue Stereo 100 Dark amplifier and Vandersteen 2ce Mkiii speakers (-3db at 29 Hz). I use an Icon LA 4 preamplifier. I have an 1. An SVS 300 subwoofer, 2. A Triad q3 inch, 700 wat subwoifer, and 3. A Snell 18 inch subwoofer with 499 watts amplification. . I tried to use the REW Software and the parametric SVS 3000, but could not obtain a smooth bass frequency response. I think I need a crossover at 70% below the lower limit (20 Hz), it will not overlap with my main speakers. So I am wondering if anyone has a recommendation for a good crossover for my subwoofer. I know that the Vandersteen Sub3 is designed specifically for my purpose and may be my best option.
Thank you for your time and detailed technical explanations. I appreciate your insights. While I was initially hesitant to add a subwoofer to address the 3–6 dB dip at 10–20 Hz, I understand the importance of placement optimization for the Vandersteen 2CE speakers. I will continue experimenting with different placements to achieve the best possible sound quality. Mahalo and Aloha, mschwabmmd |
OP: By letting the sub take over more Hz you not only reduce the distortion, and increase the dynamic range of your mains but you also make it possible to introduce DSP that is ONLY in your bass. That is, any problems you have in the 20-80Hz range move over to the sub and become easier to manage. Done well a subwoofer should make your speakers sound glorious instead of incrementally better. |
I had concerns about introducing a digital stage into my completely analog system. I prefer the idea of a crossover (say 40 Hz), then using the SVS3000's digital parametric equalizer to smooth out the bass.
I need to find an analog crossover since the miniDSP introduces a digital stage between my preamplifier and amplifier. I would appreciate suggestions for an audiophile-grade analog crossover. I hope I do not need to revisit my electrical engineering textbook (from 1972) and build one myself.
I am impressed and grateful for the high level of audio engineering and experience your answers bring to my questions. Thank you all very much.

40 Hz is too low. I agree with Vandersteen that 100Hz is about the right place for a crossover. It is an unfortunate Audiophile myth that lower is better, but the handful that have tried going over to higher crossovers have learned the benefit. |
