05 March 2018 - SOUND QUALITY (GIGABOOM & MACRO.II)
over the last few months...
...we have been fortunate enough to have some amazing engineers (ones employed a with VERY high-end speaker brand) (we can’t say the brand names, but HINT – their systems are found in most $100k+vehicles) help us do final “tuning” on the Macro.II and Gigaboom.
So what do we mean by tuning?
Well...there's a lot that goes into what you hear when you're listening to any speaker. Some people can hear the minute differences between two speakers when the same song is played - however, many listeners cannot. No matter which party you're in, here's a simplified breakdown that might help:
CLARITY - Hearing ALL the frequencies, distinctly and prominently. The highs, lows, mids, and sub-frequencies of each. True clarity is EXTREMELY uncommon to find in portable bluetooth speakers. Why? Because each frequency requires power - so to get them all, you need to increase the power source (so you don't compromise playtime). You'll notice most speakers do NOT advertise their battery size. We do. We want you to know exactly how big our battery is, because it directly translates to how much power is actually being put through the full range of frequencies our drivers have to offer.
When compared with other speakers, you'll notice lower quality speakers are "muddy." Frequencies are lost in or masked by other surrounding frequencies - generally speaking it means you actually lose significant portions of the production of a song. In these cases, you're not actually hearing what the artist/producers intended - instead you're hearing what the engineers of the speaker manufacturer prefer.
BASS - Low end sounds you can FEEL, not just hear. It is extremely common for most bluetooth speakers to synthesize bass tones in the low end of mid-range drivers. Why? Because a big bass driver sucks a lot of power. In order to get the same perceived sound output from a bass radiator, you need to put MUCH more power to it than a mid. To compensate for the added power, battery size must be increased, which is an expense many companies don't want to take on.
Additionally, managing the added power to the separate drivers is much more difficult than simply pushing "fake" bass through an already tuned, full-range mid driver. You don't have to do much to re-engineer the software, as you're already pushing most of the power to those drivers for your other frequencies.
If you've ever installed a multi speaker system in your car or home (i.e. home theater), you'll note that the subwoofer has a devoted power supply, and the other speakers do not. You'll also notice it doesn't really "sound" like a whole lot - but you can SEE and FEEL it. This, is real bass - and that's the type of bass you'll find in the Gigaboom and Macro.II. You'll notice at full volume, over time, our speakers will literally move position, or things around them will vibrate. This is real bass.
We've taken the time to distribute power appropriately to highs, mids, and a power hungry low end to make sure there's an appropriate balance across all frequencies.
VOLUME - The total number of decibels put out by all the drivers. Volume is a tough issue to address. We'll admit straight away to the following: you can get cheap speakers that sound loud. Our speakers send their power across many many frequencies. Cheaper speakers send their power to only a few frequencies, but louder. We choose full over loud when we must. However, to compensate for this choice, we use bigger batteries than anyone else, to make sure our volume is on par with your alternative choices.
That's all to the naked ear. To a decibel counter, there are a few speakers that may sound just slightly louder up close, but that actually emit fewer decibels. They sound louder, because the sound is "narrower." A great example of this is a home fire alarm - it chirps - very "narrow" sound that is loud and piercing. Run those same decibels across a "broad" full range of frequencies and the alarm may be hardly audible.
Listen to our speakers from far away or in a large, reflective space? Because of the "broad" nature of our sound, you'll hear clearer, fuller sound from much farther distances, as opposed to a pointed, muffled sound from "narrower" speakers at the same distance away.
