    Re: Damaged 511b

    Was I really only putting in 1.5 watts at -18db?
    Probably, allow a ~10% window of error. Exact power input is a difficult thing to calculate as it's impedance dependent, and the impedance is frequency dependent. 8/16 ohms is a nominal or average rating on a driver. The acoustic load(horn) and frequency will determine actual impedance seen by your amplifier.

    I'm aiming for a 120db system to allow close to reference levels at 45 feet for home theater usage.
    Pascalites and an XO of 800hz or higher, 1200 would be preferred, at least 2nd order.

    I hear them, muted pretty much, but the "sizzle" for lack of better word is missing.
    Pascalites.

    I'm using an Ashly FET-200
    Likes me some Ashly's, got a short stack of em here.
