SA-8 Power vs. Box Size

[sundownz]

Box size has alot to do with mechanical power handling. If you are going to be pushing your woofer beyond it's rated RMS power you need to be very mindful of this fact and put the woofer in no larger than the minimum suggested enclosure for music program.

We design our woofers for very small enclosures and power ratings are there for a reason -- you can continue to push a driver like the SA-8 beyond RMS power and it will not be stressed whatsoever thermally by the time you can cause mechanical issues. The motor, especially on the SA-8, is VERY strong -- being an 8" driver there is limited mechanical throw available. The driver retains high motor force all the way up to the point where you can start breaking it.

In any event... based on my testing so far you can expect something like the following on mechanical power handling vs. ported box size on the SA-8 :

1.25 cubic feet = 300 watts

1.00 cubic feet = 400 watts

0.8 cubic feet = ~450-500 watts

0.6 cubic feet = ~500-600 watts

You may ALSO need a subsonic filter depending on box tuning. The rated RMS power is 400 watts RMS -- if you push past that you are voiding warranty coverage. We are bringing in re-cone parts and they can be fixed, though, for those of you who like to push things. If you have any doubts about your ability to monitor your listening habits just stick to the 0.60 recommendation.

To re-iterate... they are not fragile. I have ton ALOT of testing on them with enormous amounts of power -- the above considers full bandwidth music program that can drop to very low frequencies and is a safe suggestion.

If you are an SPL competitor then you probably already know this and these suggestions don't really apply for burps @ tuning. We have put in excess of 600% of RMS power on them for SPL burps.

Sweet Jesus. over 2400w rms to an 8"? Those are some solid little fuckers you've got going over there. You guys at Sundown are always setting the bar even higher. Great job!

Yep -- in this video right here clamped ~2500 watts :

[jagblazer01]

do you think 1.5 cubes is too big for 2 of these if im gonna burp them with 3kw to the pair?
