2x on impact driver.

gain is not a volume control :|

could be especially useful for db drag mr.p - Cant find much info on them on the net, but sounds like possibly a similar outcome. Yes, the circuit operates at the frequency you tune it to.

http://www.audiocircle.com/index.php?topic=53322.0 Its 3am and i've been reading a few threads on this since about midnight.. the basic effect is that at low frequencies dampening factor of the amplifier is reduced to allow the spider(s) and surround of the driver to do their natural job. While this is more oriented towards SQ design and open baffle drivers, it may be an interesting concept to test on an SPL based system to produce more excursion (and in effect lessen clipping effects on the driver due to bypassing of dampening signals) at a tuned frequency. More excursion means more spl.. most of the time! If you know someone to point to this thread, do so http://server6.theimagehosting.com/image.php?img=T-bass.PNG

tig/mig. use a damp cloth to protect against spatter.

build a horn in your door for your mids Lots of room behind the panel to curl the mouth of the horn into a large opening that aims front/back/top/bottom, like a flat sea shell

what did you use for a load?

hmm.. might have to try and build a WO32 (obviously will be changed...) to sqeeze some 18's into.. on 4KW... haha.

like I said, dont bother doing it on an amp you love lol

basically no. technically yes.

what about alternator? Stock electrical wont kill amps though as long as you treat them well. 1 batt/2KW is my rule when short on alts, havent cooked anything yet.

mid-high 40's iirc.

you forgot mosfet strapping. Easy to do but dont bother doing it on an amp you love lol

If you're using a multichannel amp or multiple amp setup on a multi coil subwoofer you need to do two things. First you need to make sure the signal being sent to the amplifier(s) is mono, not stereo. Second you need to gainmatch. If you send a stereo signal to the setup it will cause the coils to "fight" each other slightly. Even a perfectly matched system can do this somewhat and some coils can cause this as well depending on how they are wound and how evenly saturated your coil(s) are with magnetic energy. I really recommend against using multiple amps per subwoofer to the average person, let alone multiple channels to a single sub (often this is worse).

I like keeping the amps separate. Not much else to say really.

or find a bolt that mounts your body to the frame and bolt to that.

put them on a 2ch amp at 2 ohms each channel, will do fine. As to using shit wiring to cause impedence rise, thats basically asking for a fire.

big black "tarp straps" make awesome spiders

two triangle ports, one in each top corner? Would be badass. Flare the end in the box so they're more efficient.

MA Audio HardKore 18's are 4".. not easy to get anymore though.

fuck assus.. between myself, friends, and other people we know, we've killed over $10,000 in Assus motherboards.

Sometimes, but this thread is about excursion and not flex....
