This includes almost all of the lowest Bass notes from musical instruments. The more expensive (and usually larger) Subwoofers can extend that low end down to, say 15Hz. Hertz is a label used to represent frequency in terms of cycles per second. Again, it is NOT an issue with the audio output quality of any of the speakers, or the Subwoofer. A good Rule of Thumb is you don't want your Crossover to be higher than 100 Hz. 12dB, you'll recall from my discussion of Balancing Speaker Volume Trims with an SPL Meter is about a factor of 4 in perceived volume. For main speakers: the recommended crossover frequency is 56-60 Hz (high pass). But again, expect to have to go up in size (and price!) I'm a car audio fanatic and always have been. Crossover frequency and crossover basics summarized, What Is A Crossover Frequency? And so even ONE Subwoofer can handle the Bass from ALL the regular speakers without confusing the audio imaging. If you measure Bass volume using a microphone shifted across the width of a typical sofa, you can easily get variations of as much as 12dB for Bass frequencies so unfortunate as to be strongly impacted this way! even MORE to get a Musical design which also has Bass extension that low. The negative symbol is used to show they represent an attenuation, or reduction, of the signal. That might not sound like much of a difference below 30Hz, but it REALLY IS a big deal! Midrange drivers in a 3-way system often do not perform well below 500Hz or 250Hz in many cases. Or, of course, you could upgrade to better speakers! If you know your speaker’s frequency range, set the crossover point roughly 10 Hz above the lowest … Good low-pass frequency range for subwoofer bass & blocking midrange sounds. “Hz”, “KiloHertz”, “kHz” are shorter ways of writing it (Kilo = the thousands marker, as you might recall from math class). Crossovers (and a lot of other audio electronics & equipment) are measured using Decibels. and order it is (1st order [-6dB,] 2nd order [-12dB]. And this should start you thinking, "How do I get the Bass audio into it?". To set up the crossover frequency for your speakers, you need to engage in critical listening. Great compromise between full-range sound and midrange bass capability. (If you DO have speakers which plug in to wall power, and have driver elements specifically designed and amplified for Bass (at VOLUME), then what you've got your hands on is a speaker with a Subwoofer built into the same cabinet! And thus the Bass frequencies they share in producing across that Crossover octave -- from your chosen Crossover Frequency down to 1/2 that frequency -- couple to the room DIFFERENTLY from each of them. When you change that, it dramatically changes the crossover frequency! In essence the Subwoofer supports the low-end of every speaker (along with handling the special, LFE Bass audio). In other words, a 2-way speaker design can produce a clean, detailed sound. Ok, I misunderstood what you meant before. Hi there, as you can see from the diagrams in the link I sent, yours is likely a 2nd order (-12dB/octave) crossover. The crossover frequency used varies by design needs, to there’s no “one” crossover frequency that works in all cases. This is based on my experience with speaker design and many stereo installations. 2-way speakers are the most common type in the world, and many offer low-cost with great sound. You can also just pick up some ready-made crossovers to save the time, money, & hassle if you like. In your case, if your main speakers really do go down to around 60 Hz before hitting their -3dB point, I would start by setting the crossover in my receiver to the THX recommended standard of 80 Hz, which should give you a nice overlap in the transition range. Basically, they offer several adjustable filters so you can prevent a range of musical frequencies from going to the wrong speakers. Yeah, that’s good belief, you succeeded! Meaning you may have to step up to a larger, more expensive model to handle the size of your listening room. (Which of course is how crossovers work!). For discussion, let's say, perhaps, 60 Hz at the low end up to 100 Hz at the high end. All sound frequencies after the crossover frequency are cut more and more past it, with an increasingly steep reduction – to the point where they’re almost completely blocked.
