Boombox Wall With Google Home? Advice Welcome!

cascades are a good idea.. the eighth one would be nicely phasing!

the vol and control issues of the earlier reply by Tadasas99 could be minimised by placing each box so the drivers are all aligned. with arrays its the alignment plane that affects the sound overall the most.. a few centimetres is enough. the difference twixt each driver power and tone becomes less relevant. having eight mixed stereo signals clustered would muddy the sound a bit.. but not enough to ruin the experience of them all singing together. a mono signal distributed to all would give you the ‘best’ sound... or mono to the centre four and the two pairs on either side a mono of the left and mono of the right. eight booms means sixteen channels... you could get clever with bessel’s but if a good loud hi-fi like Massigan, Cornerstone, Tubbys RDK or Abi Shanti has taught us anything .. a huge pile boxes at full stretch keep them feets movin in mono!! eight boomboxes on a wall aint about subtle, its a charectorful significantly boisterous and engagingly delightful noisey fun exciting experience. Alignment of drivers will be key before relative amplitude or tone twixt the booms.

ha ha! i wanna be there !!! i gatta tape !! theres bogglin to do

 

er... just a clarifying deet ... 0.41” is about a 20microsecs delay which would significantly affect intelligability of any lyrics... so if your drivers on each box to to box are out by half an inch youre allready compromising the sound. to the point where eq/tone control or even the volume cease to be relevant . line em up! get that plane right and itll be easy to tweak tone / volume and the dispersal of sound through the room will be enjoyed by everyone.

 

ok.. ive had my cawfee...

so ... make two stacks... stand each boombox on its side .. put the next onto but the other way round and twisted 30degress in axis... next on top but other side again down twisted back... and again ontop of that.
two stacks of four boomboxes ... all on their sides... all drivers aligned down a central axis... each stack with each boombox inverting and reversing belows axis.
put each stack in either corner...
then youve made a pair of omnispeakers or orthospeakers which would give out a complex stereo with less combfiltering. if you get the alignment right... they would sound like a function one sound system at its best.
if you got encouraged and found another boombox. ... then hang that upside down right up in the angle of ceiling and wall right behind you other end of the room.. a rear inverted stereo. spreader!!!
er.... obvs the shelves have to go... more room for dancin... people will go, “why are they on their side?” but when you smile and point at ya room fulla dancin freakyTapey people i think they’ll forgive you and get their wriggle on too.

ok... hows that for a left field cup winning slam dunk?!!

 

on the back of an envelope itd look like this... use a bit of imagination... forgive my arthritic scrawl! ha ha

 

You could go for something like this. Behringer HA400 Microamp 4 Channel Stereo Headphone Amplifier https://www.amazon.co.uk/dp/B000KIP...abc_KXD1DK1ENBPXAZGQ1GNQ?_encoding=UTF8&psc=1

gives you multiple outputs from a single input. If you had a couple of those and use something like the Googlecast audio or something similar to can stream simultaneously using Google. This way you have a clean signal to each box
