    ED e3.8 vs Infinity Reference 860w

    I have a dual 8" sealed box i made for my reg cab truck. It's .41cf each side.
    I'm leaning toward the Infinity due to the 8db better sensitivity but not sure if that
    really means anything. Have 500 watts to a pair can be either D2 or S4 subs.
    Any other suggestions for this box?

    Re: ED e3.8 vs Infinity Reference 860w

    Well for starters the ED's come in d2 and d4 and the Infinitys only come in s4.

    The Infinity has slightly less motor force and xmax and a higher fs. I wonder about low end performance because all the other Infinity Ref subs have a low tune for the recommended box, but the 8 has an fb of 40hz. I wonder if thats to impress noobs or for warranty purposes or what.

    The ED's only have a 1 1/2in voice coil vs 2in on the Infinity



    HEre are tsps for the Infinity since the site isnt working:

    You're recommending something you've never even used... The SA-8 is quite possibly the worst 8" woofer for sealed applications.

    OP, check out the Image Dynamics ID8 V3. It is rated at 150W RMS, but it can handle the 250 if you take care of it.

    You are right about not using it before but with the price tag on them and reviews i have read so far, they seem to be a good woofer. With the ops setup he would have room to play with in tbe future if not satisfied with just 250 per sub

    read between the line and you see he asked if he should go with the eD or the Infinity first. Then asked for suggestions
