Low Cost Surround Sound Upgrade
Designer: Joel Hornbostel
Project Time: 1-8 hours
Project Complexity: Hobbyist
Project Cost: $100-$500
I had upgraded my surround sound system and was giving one of my daughters my old system. But it just did not have speakers I liked and wanted to give her more. Unfortunately the budget was very tight. Since I have not built speakers since high school I went to the web to see what I could find. Thank you Parts-Express. These are the speakers I put together for her.
297-428 HIVI B3N 3″ ALUMINUM DRIVER ROUND FRAME
279-001 1/2″ MYLAR DOME SHIELDED TWEETER 8 OHM WITH 3.3 OHM RESISTOR
Home Depot has oak hobby boards for $2.99 5.5”W x 24”L x 7/16” thick. Two boards each speaker.
I used the width of the boards unchanged except for the center speaker front and back, which I ripped down to 4.5” wide. The speakers are 7″ tall plus 2 times 7/16 top and bottom plates. All are butt joints glued together. I have retired and moved to a house boat and no longer have a shop. So I only have hand tools, just trying to keep it simple.
As far as cross overs I used the tweeter side of the Panasonic cross-overs on sale. I know this is not the best but the cost was right. I soldered wires to the tabs (see picture) for the woofers.
I finished the cabinets with shellac since it is easy to apply. This is what they came out like. By the way they are much better sounding then the speakers that came with the system. For around $20 each and $30 for the center, they are a great improvement.
As a father of daughter myself. The memory of her dad making that for her. Makes those speakers priceless as time goes on. Way to go being a Dad the way Dads are suppose to be. But unfortunately seems in today times. That trait seems to be a rare thing to find now days.
