Guys - As is typical, people who have no experience with our products are making up the most nonsense about our products, so I thought a Q&A thread would be useful.
1. Do Dayton amps shut down when driven into clipping?
We do not have amps that "constantly shut down". When Ethan and Adam tested our sub, they got to appx. the same SPL as the eD sub with no shut downs.
Other members have noted they can drive the HECK out of our subs, but then an occasional scene will cause it to shut down.
One such scene is the Ska-Doosh (sp?) from Kung Fu Panda. This scene was tested by a Tech-Talk guy at Parts Express.
It turns out there is a transient on that scene that is 6.5 times as strong as the rest of the scene.
So - if we are driving the amp to, say, 600 watt peaks into an SS-18.T or SS-18.2 on "normal bass" from that scene, suddenly the amp thinks it needs to deliver 3900 watts.
It isn't the power amp protection that kicks in here. It is the input overloading on that scene. The circuitry reads this as a voltage spike, and will shut the unit down in rare occasions.
This is normally also when Audyssey is engaged as well.
When this occurs, simply turning off the amp for 10 seconds and turning it back on will solve the problem.
Again, this is not common - it is rare.
2. What does the blue light which can flash red mean on the front of the amp?
The blue light means the amp is operating at less than half capacity of the unit. As the red light comes on, it begins at about -3 dB in power, and will stay on steadily until about a +3 dB peak is hit. Occasional flashing is not a sign of clipping.
3. What does it mean when I see "modified Dayton amp" or "stock amp" in other threads.
This means that either the eq curve or subsonic filter has been changed. There is no way of modding the amp to get "more power". There is no way of modding the amp to change the input protection circuitry.
The standard bass boost is about 3 dB.
As noted earlier, our boost is a little more.
4. Why doesn't CHT boost the lower frequencies more as much of its competition?
All sealed subwoofers require a certain amount of boost in the bass to flatten the response. The more boost used, the less headroom the system will have in other areas.
Subwoofers are not designed to play a 20 Hz signal outside. Subwoofers are required to play a complex set of signals from 10 to 80 Hz in one's own system.
Chase Home Theater spent considerable time looking at the predicted room response of literally dozens of theater rooms.
We selected a more mild eq in the bottom end of our subwoofers, as this allows our subs to quite often play into single digits in a user's room by working with the room's acoustics and room gain. Outdoors, our subs will be appx. +/- 3 dB from 24 Hz and higher, with a natural 12 dB per octave below the 24 Hz signal. This meshes will with most systems and room gain.
We could easily increase the boost, and show a flat response to 20 Hz, but this would rob headroom in higher frequencies while often resulting in boomy bass in one's own room.
Our included parametric EQ will assist in rooms which don't have much room gain, and these larger, more difficult rooms will often require several subwoofers to achieve a linear response to below 20 Hz.
5. What effect do the Bass Boost and Subsonic filters have?
The bass boost provides a 5 dB boost at 24 Hz, and the slope starts at about 42 Hz.
The subsonic EQ is not needed with our sealed subs, but it's effective point is 18 Hz.
