The 2.1 channel design, capable of 200 watt RMS, uses a pair of 3" aluminum cone woofers and 1" titanium tweeters with a single 6-1/2" high excursion subwoofer. This compact package produces crystal clear midrange and highs with incredibly powerful bass response.
Description:
Blast Box 200 Watt Portable Bluetooth Speaker Kit
Courtside, poolside, in the yard, at the beach, on a picnic, etc.…the Blast Box portable Bluetooth speaker has the power to cut through most background noise and gives you the music you crave wherever you want it.
The Blast Box speaker kit is a battery powered portable Bluetooth speaker that gives you the freedom to bring home stereo quality sound with you wherever you go. The powerful 2.1 design delivers high output with excellent off axis response to effectively fill large spaces with amazing sound. The simple on-board controls allow you to tune the sound to fit the environment and even control your media player directly from the Blast Box speaker. A 3" aluminum cone woofer and 1" titanium dome tweeter on each of the stereo channels provide accurate response with incredible detail. For the low end, a 6-1/2" high excursion subwoofer is matched with an 8" passive radiator to deliver natural deep bass response with power and authority.
Outfitted with all Dayton Audio drivers, you can be sure that the Blast Box Speaker is capable of outstanding performance for an unbeatable value. Dayton Audio's ND25TA-4 1" titanium dome tweeter handles the high frequencies. This compact tweeter includes a copper cap and Ferrofluid cooling to ensure low distortion output with high power handling. The DSA90-8 3" Designer Series aluminum cone full-range driver takes care of the midrange and mid-bass response. The powerful low distortion motor and aluminum cone ensure incredible detail and accuracy, making it a great match for the tweeter. For the lowest frequencies, the Blast Box uses a Dayton Audio DCS165-4 6-1/2" Subwoofer matched with a DS215-PR 8" Passive Radiator. With an incredibly powerful motor and high excursion capability this subwoofer has the capability to match the SPL levels of the mid and high frequency drivers all the way down into the lowest frequencies. The passive radiator design allows the enclosure to be incredibly small with extremely low tuning, which keeps excursion under control and allows powerful output to less than 40 Hz. All of this is powered by the TPS3116D2 Class D 2.1 Bluetooth 4.0 Amplifier Board, which is capable of 200 watts RMS of output. Thanks to the available power and excellent set of features, this amplifier makes the Blast Box a potent and flexible portable system.
The enclosure for the Blast Box is designed to be easy to assemble and extremely rugged. Made from 1/2" thick high quality Baltic birch plywood, this box can take a beating and is much more moisture resistant MDF. The panels have all been precision cut with dadoes and rabbets for every piece making assembly a snap. The clean lines and classic look makes finishing simple and leaves plenty of room for customizing allowing you to give the Blast Box whatever look you want.
This kit includes nearly everything you need to build a high end portable Bluetooth speaker in no time flat, including: a knock-down enclosure, drivers, crossover components, amplifier, batteries, wire, hardware, and connectors.

One tip from my experience for anyone looking at this project; the instructions say to cut the speaker wire to 12" sections. That isn't quite enough to tie them up neatly off to the sides. I would go 14 or 15".

[@konkilr]

Need this system in a 2.1 arrangement! I have the blast box. Mine is the blue one in the video. I converted mine to 24v. Much better with 24v. Love this system! So powerful and clear!

[@chem119]

How'd you do it and what did you use? Currently building mine.

[@konkilr]

@@chem119 I followed PE's instructions to use a relay to connect 2 power boards in series.

[@jeffwhiteman9520]

Been trying to do 24 volts too. Where did you find the instructions on their website. All I find is how to hook 2 up for longer battery life

[@konkilr]

Send them an email asking about it and they send you the schematic.

[@justins.1283]

I use the battery pack from an 18 volt cordless drill let the motor burn up on it and it works quite well for those amps plus I have several battery packs so they can be swapped out when it's dead

[@Grand-Master-Azrael]

Box finished: *Russian Hardbass starts playing*

[@Derien-Lambert]

Thanks!

[@vapingwithjames3370]

Please come out with a DIY bookshelf speakers with 8inch woofers. Thanks and great video

[@justins.1283]

There are so many box calculators Like Win ISD ,Bass Box pro etc. Pick your driver's and what you want your sound to be and design your own. First attempts don't have to be perfect, good looking, or even sound good with all types of music. I've never been happy with any build when it's done there is always something to be tweeked . Be forewarned that building speakers is addictive and not always spouse friendly!

[@badtothebonne]

I want to make my own box and I have speakers I need the amp and Bluetooth and what other things do I need

[@juststuff5216]

PE FTW :)

[@SinnerSince1962]

Maybe I missed it, but I still don't understand how it's powered? By the 3 cells you installed? If so, how do you ever get to them to replace them someday?

[@michaelcraig2115]

Rechargeable batteries most likely - as seen in other projects

[@GhaliaVillanueva]

Magnific. Music name please

[@TobyIKanoby]

the outro is great

[@PartsExpressOfficial]

Killer! Thanks for the compliment and comment!

[@TobyIKanoby]

@@PartsExpressOfficial the build is nice of course, but to see the creativity of the customers is just great! BTW, I just got an amplifier board of Arylic, I saw Parts Express doesn't sell those, you should really take a look at their products, the features they offer are off the charts.

[@bassblaster505]

i feel like the Blastbox and Executive are being heavily let down by only having a 12V supply from 3 18650's in series. TPS3116D2? knock of of the TPA3116D2 i think. ive played with those chips at 12V into a 4 ohm load your only getting about 15W. you can JUST hit 20W if you push it into clipping. give it a 24V supply and it should be a happy speaker system. THEN into 4 ohm you'll easily get 60W.

[@konkilr]

I converted mine to 24v. Plenty of power that way!

[@bassblaster505]

@@konkilr That's the way this kit should have been, especially since a reputable company like parts express is advertising it as 200W.

[@justins.1283]

I have that amp using it for a different application with an old laptop 90w 19.1v power brick with two 4 ohm bookshelf speakers and an 8" 4 ohm subwoofer . No sure of the wattage to each speaker but in a 10'x14' room it can get up to about 75% on the potentiometer before any distortion is audible . Thats way louder than a comfortable listening level.

[@nickparkin8527]

@@konkilr how do you convert it into a 24V?

[@konkilr]

@nick parkin Email Parts express, they have a diagram on how to do this

[@BLacknesmonstaz]

Let's hear it!!

[@PartsExpressOfficial]

Later this week ;)

[@d.s.w7779]

Need to add aux input

[@barnabyjones2145]

would be nice if it came with 3.5mm or RCA jack to plug in music as well

[@eksalsani8659]

Seandanya bisa di beli di indoenesia😊

[@johgus96jg]

Wtf there are two woofers at the end???

[@PartsExpressOfficial]

For the lowest frequencies, the Blast Box uses a Dayton Audio DCS165-4 6-1/2" Subwoofer matched with a DS215-PR 8" Passive Radiator.

[@nightryder21]

KMA "inspired"? Lol

[@steamy1225]

Not bad. I built one about the same dimensions but with a car media player and car speakers. Sounds great. Half the cost.

[@123wmc]

As an audiophile and a woodcrafter, half the cost is impossible if apples to apples. Maybe it sounds good to you but you did not buy a media player and buy the speakers for half the cost much less the pre cut cabinet which would cost you $80 minimum for a half sheet of Baltic sheet goods and you still need expensive tools to build the carcass not even factoring in the design of the speaker box. Still not even bringing in the battery function. People are drawn to that box because of the value. Throwing speakers into a wood box with a car stereo headunit....not really what is going on here....nice try.

[@steamy1225]

@@123wmc What ever dude. Car media player $20 at Walmart, Speakers $20 at Amazon, 3 sheets of plywood 20x20 inches or so from Menards $30. 12v battery $40 at Amazon. Charger $25 at Amazon , Plus a $3 switch and and $7 charge plug . About $150 . And i did build teh box from scratch with just a jigsaw and a table saw and a drill. No expensive tools . You do the math. Done. This kit in the video is $259 .

@@steamy1225 I'd love to see the results of your build!

The sound on this video is terrible!!!!! I hope this speaker doesn't sound like this!!!!!
