I built my 2 living room Hifi Floor standing Speakers + subwoofer and centre speakers….DIY_DAVE
This speaker set includes a 200 watt RMS subwoofer, 2x 50 watt centre speakers and 2x 800mm high 3 way speaker towers @ 300 Watt each. The amp comes as a kit with tiny speakers that are really loud but not as full bodied in the midrange frequencies. So I decided to build my own mid woofer speakers.
MDF sheets – I used 3 sheets in total (1.8m x 800mm @ 16mm thick)
fiber padding (Bed sheet stuffing)
30mm wood screws
Speaker drivers taken from Sony HiFi system – (MGH RG440S) (2x mid woofers, 2x mid/high woofers, 2x tweeters, 1x 8″ subwoofer) Centre speakers were from a previous build – unknown make/model. (3″ 50watt drivers @ 6ohm)
Reel of speaker wire (I used copper premium oxygen free)
Onkyo HT-S3700 5.1-Channel Home Theater Receiver amplifier
3-way passive crossover – (to split the audio frequencies)
In order to design the enclosure from scratch you need intricate details about the drivers like the resonate freq and the air displacement of the unit. Something you won’t get looking at the manual of a hifi system or the back of the speaker. Although this may be outside the scope of this instructable, some may find it useful. Providing you know this information you can use this fantastic calculator to work our what type, shape and size your new enclosure needs or could be. (Calculator/Box/)
