Soundsystem Inspiration

Toronto: Montreal:

Goal

Soundsystem that is: While audio power can be achieved with many speakers, this may not be very portable (or easy to store).
Also, while audio power can be achieved with less speakers by supplying more power to the speakers, this may not be feasible with the available non-commercial electricity.
Therefore, need a speaker design that can provide the most power for the least amount of drivers and efficient amplifiers (minimal heat loss).
Also, it would be useful to have a system that could be expanded and added onto over time. A passive speaker solution with central amplifier allows this easily and allows for easier powering and control from a central unit.
A passive speaker setup also allows for separation of the "hardcore" electronics (amplifier) from the more resistant speaker boxes (solid cabinets with speakers and speaker wire to a jack panel).
While amplifiers are better left to the pros, rigging speakers and cables to a jack panel in a wood enclosure is a realistic DIY project.
However, I would want to avoid just making any rough or improvised cab and experimenting through trial and error - a well proven design will already have the efficiency people count on from the off the shelf product.

Off the Shelf Speakers Cost

As of January 2025, 1x Danley TH118: $4789 USD or $6875 CAD + tax

Price(w/out tax)
1x TH118 $6875
2x TH118 $13750

6x XOC1 TH18 $10680

Amplifier Costs

I still have lots of research to do about suitable amplifiers as well as budget friendly amplifiers.
However, cost permitting, a Linea Research amplifier seems ideal. Assuming 1x TH118 or XOC1 TH18 is 3400 W,
Max Watts (Subs)
1x XOC1 TH18 3400W
2x XOC1 TH18 6800W
4x XOC1 TH18 13600W
6x XOC1 TH18 20400W
8x XOC1 TH18 27200W

Plan

4x Xoc1 TH18 (B&C 18SW115 Drivers)
4x Cubo Kick 15 (? Drivers)
4x Highs (Homebuilt could be MT-130, SMT 212, MT 121, MTH 30)

For first iteration, highs can be off the shelf (Yorkville, QSC, JBL, Turbosound, etc.)

If after a year or more of use of this system has at least paid it off, then can think of expanding by doubling it.
