Supplies for building the PLUTO subwoofer

Some items for building the subwoofers can be bought from LINKWITZ LAB, like the two blank printed circuit boards with material list and loading chart, or the fully assembled and packaged crossover/equalizer electronics. Everything else is a DIY project. Some unfinished wooden cabinet parts may be offered by Wood Artistry in the future but probably not a complete PLUTO or PLUTO+. Unlike for the ORION there is not enough value that WA can add to justify the necessary increase in cost to you. Without such increase it would not be a worthwhile product for them. Thus, if you need help, try to find a friend who is willing to lend you a hand. He/she might build a system for themselves at the same time. Your license to do this is the purchase of a set of PLUTO construction plans for each builder. I guarantee that you will have to look long and hard to find a commercial loudspeaker that comes even close to the PLUTO+. I say this with some embarrassment in light of my previous efforts in designing speakers. PLUTO+ is not an accident, but its performance far exceeded my expectations. 

The table gives material cost estimates for building a pair of subwoofers yourself.

  w-ASP printed circuit boards (2) with material list   $50   Inventory Sale!
  Electronic components   $90
  Cabinet   $60
  +/-12V/300mA power supply (115VAC)   $60
  Peerless 10" SLS 830668  (2)   $125
  Binding posts (4), cables (2), interconnects (4)   $60
  Plywood, screws, glue, paint, etc.   $50
  120W AT1202 stereo power amplifier    $620

  Estimated total   

  $1115 plus shipping



The w-ASP printed circuit board makes building the electronics easy. The locations of all components are labeled on the pcb and in the supplied material list. So it is a simple matching operation to insert and then to solder the components from the backside of the sturdy pcb.

The cost of one w-ASP pcb is $25    Inventory Sale!
It includes the PLUTO+ material list. 

For shipping add $10, US or international, for up to 6 boards.



Building the subwoofer electronic section of PLUTO+ on your own might be too demanding or time consuming for your taste. You have to order all components yourself. Their cost is around $200 plus $110 for the two w-ASP circuit boards. We can provide a fully assembled and tested crossover/equalizer similar to the one you see on the right. It comes with a clear polycarbonate cover for easy woofer level adjustment and woofer in/out switching.

The cost of the PLUTO+ subwoofer crossover/equalizer is $600

Shipping is $25 in the US and $50 international, also with a power supply included.

What you hear is not the air pressure variation in itself 
but what has drawn your attention
in the streams of superimposed air pressure variations 
at your eardrums

An acoustic event has dimensions of Time, Tone, Loudness and Space
Have they been recorded and rendered sensibly?
