I'm in the final throws if deciding which sub to go far (1000 w subM or a funk 18.1)
Does anyone know if there is a max burst graph for the subM with the 1kw amp?
Tuned to 18hzIt's ported, so below tune, it will roll off at 24 dB/octave, (although it has an internal DSP that might roll it off faster than that for driver protection.)
+/-3db variable from 16-30hz, to 40-150hz, customizable, contact us for more information
124db maximum output at 2m ground plane
S/N ratio >113db at full rated power

Just got my submersive hp+ slave unit yesterday! I have them placed about midway down on the left and right wall and it really made a noticeable difference in bass response of the room. Now i no longer feel like the bass is focused at the mlp but now over the entire listening area. It is wonderful. I was a bit concerned about the diff in delay being that they both receive the same same signal, but since there is only a difference of about 2ft from the mlp to each sub then i figure that's less than a 2 millisecond difference, which i do not discern in the least. Definitely made the right choice! I wonder how many milliseconds it would take before it would be noticeable. I googled it but didnt really find anything.
Anyway, i found it funny last night that i wanted to watch "Lone Survivor" when my wife started streaming her spotify (free acct - not great audio source) and i couldnt get her to turn it off because she was enjoying it so much! I was laughing inside because i found it funny (and gratifying) to see her enjoying it so much!
Both of my units are black maple, but my master sub shows a good bit more wood grain than my new Slave unit. I actually dont really see much grain at all in that unit. I confirmed that i ordered both maple (not oak) on my invoices, Mark's records, and the box labels, so i wonder if thats common/expected to some degree. Anybody else experience something similar?
Enjoy the holiday everyone! Some of the "BOOM" on my block may not be from the fireworks! 8-)
A few random questions:
1. Does it matter if a sub is close to a wall (in my setup there is only 0.5 feet separation)?
2. I take it is perfectly normal to be able to feel vibrations on the top and sides of my sub?
3. Currently my avr has the sub level set at -4.5 dB. I remember Mark saying that this level should be below zero. Sometimes when I've bumped up the sub level I've gone above zero (so far the highest I've gone to is +2.5 dB). Do I need to adjust things so that I never go above zero? What is the reasoning for keeping the level below zero?
