In Reply to: Sub Questions: Speaker-level vs Line & Crossover Setting... posted by VynylTap on January 3, 2009 at 08:18:00:
REL strongly recommend the speaker line connection because they say it retains some of the characteristics of your amp in the sound and improves the blend between sub and mains so if you've got some speaker cable and you don't have an interconnect, it's a good connection to start with.
When I tried introducing my REL into my audio system (ported sub and ported speakers) I started at the -3 dB point for the sub's crossover (actually it isn't a crossover in this case, it's a low pass filter for the sub) and discovered that frequency was too high. The REL manual also states that the 2 main problems people have is setting the LPF frequency too high and the sub's gain too low.
Certainly start at the speaker's -3 dB point but remember that's probably an anechoic measurement, not an in room measurement, and what's actually happening in your room will be quite different. I suspect you'd be better off starting at around 30 Hz or so and you may even need to set it lower than that. I ended up with the REL's LPF set to 22 Hz, as low as it would go, and the specified -3 dB point for my speakers was 37 Hz. Your mileage will obviously vary with different speakers, different sub, and different room to me but I'm prepared to bet that your -3 dB point of 45 Hz will definitely be too high.
