There are plenty of large cabinet, large baffle designs that people enjoy. In another “however”, you may prefer to hear the cabinet. The cabinet is a passenger that’s doing it’s own thing. I want to hear only what the driver has to say - it’s the most capable of reproducing musical information properly. My personal philosophy is I want the smallest baffle possible. The large baffle creates a lot of reflections which produce smearing and distortion. ![]() The wizzer cones are not exceptional at very high frequencies.īut again, it’s all a series of tradeoffs. It uses a paper wizzer cone (in the center of mid) to reproduce high frequencies. Interestingly, THAT specific speaker is a prime candidate for a super tweeter. It’s size (relatively small) is dictated by the fact that we’re most sensitive to midrange frequencies so the driver used should be of optimal size to reproduce them. It’s small on purpose though - it’s meant to be a single driver speaker for the benefits that gives you - namely eradicating phase issues since there’s no crossover and you’re not dealing with multiple driver acoustic centers. The speaker shown above requires this because the driver is relatively small. If you make the baffle large, those lower frequencies don’t have the opportunity to wrap around - they bounce off the baffle and come forward towards you. The result at the listening position is a drop in low frequencies. What happens is, as the frequency decreases the waves become larger (wider) so instead if bouncing off the baffle and coming back at you, they wrap around the front baffle. They are generally used to augment speakers who’s drivers are not large enough to reproduce low frequencies well. Wide baffle designs that sound good are also possible as mentioned. It’s like being in love with a dynamic headphone but worrying that it’s not a planar - there’s no point. Each company and/or their speaker designer(s) have their own idea of what attributes are most important to them and what compromises they’re willing to make.Īs mentioned above, find a speaker that matches your preferences (just like with a headphone) and don’t worry about the rest. So you need more drivers.Ĭompromises are all encompassing. Big drivers are heavy and therefore can’t move fast enough to play high frequencies. So, to move a lot of air, you need a big driver. If you put your headphones in the middle of the room, you’ll hear all the highs, most of the mids and, none of the bass - the driver simply can’t move enough air. Mainly because to reproduce bass frequencies in a room vs the tiny space between the headphone and your ear, you need to move a lot of air. Speakers are not like cans where a single driver can handle the entire spectrum. You get a dedicated driver for bass, midrange and, tweeter. ![]() This takes a lot of stress off them and reduces distortion. The main advantage of a 3 (or more) way speaker is that all the drivers play a narrower frequency band. It looks like this (this image splits what I call diffraction into two - reflection and diffraction): Diffraction is when the sound wave wraps from the driver cone back and bounces off the baffle and comes forward towards you (sort of like an echo of the original wave). The more diffraction, the more loss of fidelity and, the easier it is to localize the speaker. The larger the baffle, the more diffraction. The soundstage goes beyond the boundaries of the speakers and it’s as if the music didn’t originate from them. If it’s done really well, you don’t even need to close your eyes. If you close your eyes and point to the sounds and what you’re pointing to is the speaker, it hasn’t disappeared. “Disappearing” is generally defined as sounds coming from an imaginary soundstage rather than the speaker. The “baffle” is the front of the cabinet. When you say smaller baffle, that’s on the inside of the speaker housing, or a part of the speaker / driver itself? how would you define ‘disappearing?’ would speed be a better word?
