It requires a monthly balancing in charging. We have to anticipate the voltage drop everytime the boombox discharges so to be safe, I used a 4 cells of lithium batteries (four 18650s in series).

The bluetooth amplifier board that I used in this project requires an input voltage of 8v-25v, this means we need to put together at least three of these batteries in series which will give you 11.1v of power. If you opt not to order online, just go to your local vape shop and you will be able to find a lot of these. 18650 batteries are also called vape batteries. They're cheap, common and safer than Lithium-Polymer batteries. This means, you get to store a lot of charge in small packages of rechargeable batteries.įor this project I used 18650 Lithium-Ion batteries. Most modern day appliances use Lithium batteries inside them mostly because Lithium batteries have a high energy storage to size ratio. The ported enclosure is only ideal for large speakers (+ 6.5 inch"). The cons: is that this design will require a 100% airtight enclosure for it to be effective. The sealed enclosure is perfect for small speaker enclosures, it dampens the sound given off, resulting to a punchy sound rather than the woofy effect.
There are two commonly used speaker enclosures, one is the ported and one is the sealed. They are the most common type of crossover filters, it has been and will always be the trusted and safest. Crossovers split the audio signal into separate frequency bands that can be separately routed to loudspeakers optimized for those bands.As much as possible go for the bessel or linkwitz type of passive crossovers.

Most individual loudspeaker drivers are incapable of covering the entire audio spectrum from low frequencies to high frequencies with acceptable relative volume and absence of distortion so most hi-fi speaker systems use a combination of multiple loudspeakers drivers, each catering to a different frequency band. A frequency response of 200Hz - 6kHz for midrange speakers and 4kHz - 20kHz for tweeters.Remember that the human ear can only hear 20Hz - 20kHz of audio frequencies so don't get excited if you find speakers that can go above or below the audible frequencies, it would be a great impracticality.Īudio crossovers are a class of electronic filter used in audio applications. For woofers, a frequency response of 60Hz - 6kHz are good to start with. Brands that I recommend buying are Dayton, Focal, Fostex, Seas, Tang-Band & Zalytron.Try to find speakers that can reach a wide range of frequency. To start off, Parts Express (online site) is a great source for speaker sales. I'm a practical kid, I try to buy things worth my budget. Be sure to read more articles in the net, canvas more about their prices, read more reviews and take a lot of consideration in selecting brands. Here's a step that I recycled from my previous instructable ( DIY HiFi Bookshelf Speakers).īefore you go crazy on shopping spree.
