Whether that's a typical sub crossover, I have no idea. Whichever way you choose to connect, the ultimate crossover filter is actually built into our Low Level board, the High Level circuit is reduced in level just before this occurs so that it can use this crossover filter. Setting up the high level input would take me a little longer, and I really should be doing other things right now. The easy-to-use, zero-compression, wireless system designed for S/510 and S/812. Go visit a beach sometime, frequently beaches have cliffs standing adjacent to them; the sharp filter set if you will. Starting At: £4,799.00 Lounge: Anthem MRX 720, config 5.1.4, Emotiva XPA5 Gen 2 & BasX A 500 power amps, Sony 65XE9305, Sky Q 2Tb, Sony UBP X800, XTZ Cinema Series M6 LCR, S5 Surrounds, S2 Rear Heights, KK QFH Front Heights, Rythmik FV15HP . All subwoofers use 1 of 2 types of filters; they either choose to limit and roll off just the high frequencies, allowing the bass to emerge from the sub but permitting the speaker to run full range. In some cases, you’ll be able to choose from a number of crossover slopes (the steepness of the cutoff) on your amplifier or other components. We just want to help you get at the more complete, totality of that experience it. The graphs above are with a DAC connected directly to the low level input on the sub, thus showing the REL crossover, but that's not how I normally use it. So, does this mean we have hoodwinked hundreds of thousands of customers? According to the manual, the crossover is always enabled for the high-level input, optional for the low level one. Free shipping on all orders. Mixed order. Also compatible with G1 Mark II. So between 100 and 200 a 28db difference, so probably a 4th order crossover (24db) with a little thrown in from the driver/room?? It will send the controlled signal to the subwoofer and blend with your main speakers at the intended frequency and slope. Thanks for the effort I really appreciate it! Our award-winning home theater subwoofers with wireless capabilities elevate any system. This diagram is courtesy of Williamson-labs.com. I took some quick readings from my REL Quake using an EMM-6 mike placed at the edge of the box (driver fires downward): The blue graph shows the frequency response with the low-pass filter disabled, red with roll-off set to roughly 40 Hz. Cutoff slopes of at least 12 dB per octave are usually chosen because of limitations in the frequency range that drivers can faithfully reproduce. No, but I have a UMIK1 on the way now (being shipped all the way from Hong Kong!) You need to be a member in order to leave a comment. There certainly is on mine.

I wonder if 24db slopes are typical in subs, or does it vary. Not alter it, dry it out and process it which I can assure you, the second approach does. We make it all work seamlessly by designing filters that can extend all the way down to 20 Hz on almost every model, so that you can roll off the higher frequencies lower down and allow the REL to mate perfectly BELOW the functional limit of the main speakers. For example, a second-order low-pass combined with a third-order high-pass filter. So, put on your favorite album, mix yourself a drink and kick back, you might be here awhile. 2) Choose a CO slope of 24 dB 3) Try different crossover points between 40hz and 80 or 90 hz, depending on your speakers/sub (keep the CO and slope the same) 4) Try different crossover slopes for the mains and subs 5) Try different crossover points for the mains and subs Are there other options than those? Crossover is the frequency where speakers begin to roll off, and the subwoofer starts outputting bass notes and LFEs. Setting up the high level input would take me a little longer, and I really should be doing other things right now.
