    Here are a few glue up and baffle machining pics. I scalloped the internal F6 woofer hole for improved air flow and reduced near field reflections. The tweeter is flush mounted with a 1/16" recess. The woofer is surface mounted so that it can partially overlap the tweeter flange.

    I installed a slot type port at the rear of the cabinet, constructed out of 3/4" laminated particle board. It is 8.3 inches long and measures 1 x 6.5" internally. (see pics)

    I put two crisscross type braces along the length of the line, rounding the edges for improved air flow. (see pics)

    The 3/4" particle board shelving material that I used was laminated on both sides, so, as you can see in the pics, I pre-sanded the laminated gluing surfaces with #40 grit for improved adhesion.

    The SideTowers - An F6 Corundum Build

    Greetings to all,

    This will be my entry for InDIYana 2019. I'm calling them "The SideTowers," as I built them to be tower type speakers in the sideways direction. This resulted in a very small front baffle surface area, which I then softened with multiple facets. As a bonus, this configuration gives me a little extra distance between the woofer and the internal rear wall reflection.

    Specs: Drivers: HiVi F6 & Peerless DA25 (corundum dome). Fb: 36Hz F3/6/10: 32/30/28.
    Xover: 1.3kHz; 5 parts. BSC: 6dB. Gross Internal volume: 1.18 cu ft. Weight: 37 lbs.


    This will be a ML-TL, so I modeled the line in 4 sections using the LA TL program. Without stuffing, the optimal position for the woofer was 4.5" down the line. I was going to place a small partition near the front of the line to create this 4.5" trap, but later on discovered that this was not needed. Simply stuffing the first 8 inches with 5.5 ounces of denim flattened out the 1st and 2nd line peaks considerably. And this 5.5 ounces only caused a loss at the main port resonance (Fb) of about 1dB.

Working...
