all amplifiers do have some trouble running in 2ohm mode, but ive heard of NO amplifier company that can gurentee that there amplifer is STABLE in 2 ohm mode. but they do have the ability to.
defenitly right my friend, to be hionest, i always thought 2 ohm was 2 low, and/or too much period for a venue, id stick with 4 ohm, luv it. 8 is clean yet 4 gives ya the deepness, and less resistance, besides that, ive heard the MACROTECH crown amps can be parelell wired to 1 ohm! lol, seein thats it around 3 grand, i hope it can!
amplifiers are a bit weird on ohms, like was reading in the crown website that stereo mode on the xti can do 2-8 ohms and bridged can do 4-16 ohms, but it don't tell you the power @16ohms, and also one thing people get wrong is that 4x speakers gets you 2 ohms not 3x, 3 speakers gets you 2.75 ohms (i recall)
ill admit they can be weird lol, just gotta work with em, now on ohm independence, ibridge is high ohm's cause more power being pushed, more safer and its just plane how xti work, now stero mode(perchannel,) will always hit clean, and lower on ohms, cause of less stress rather then bridged giving most power it can, reconizing sub(s). im good with 4 - 8 ohms, 16 is rediculously high, and way to resistant!
Yes True, but im thinking of designing a speaker with a couple of switches on the back (dual 18" subwoofer) that can change the sub between 16 ohm and 8 ohm, which means you would have more versatility when hooking up the speakers, for me it would work well, like i might use only 2x cabinets (one each side in 8ohms) or 2 either side4x in 16ohm, and dasiy chain 2x on either side together making the load 8ohms on 2x dual 18" subwoofers (just need a big amplifier tho like the XTI6000)
@jamesduty92 Amplifiers are rated to have the ability to power down to a minimum "ohm rating" (I.E. nominal impedance) for a few different reasons, most of which are due to the fact that lower impedance external loads allow more current through the output circuit(s) of the amp; it's simply ohm's law. Because all amps (and indeed all non-superconducting circuits) have an internal resistance (though hopefully very low), power is "burned" inside the amp, which creates heat.
@jamesduty92 If heat builds up inside any part of the amp faster than it can be dissipated for an extended period of time, the amp will fail. But there will usually be other problems with the amp caused by driving such a low impedance load, which arise well before the amp actually fails. One is that the voltage across the speakers will sag significantly, causing high distortion. Distortion plays a key role in how reputable amplifier companies assign power and minimum nominal impedance ratings.
@jamesduty92 (Another, related, issue with driving lower impedance loads is reduced damping factor.) The range of impedances most amps are rated for is basically the range where you will be able to send the most amount of power possible through your speakers, while maintaining an acceptable amount of distortion caused by the amp. The higher the impedance of the load, the lower the distortion (though distortion is usually (and ideally should be) negligible above the minimum rated impedance.)
@jamesduty92 The trade off for this decrease in distortion is a decrease in power to your speakers. In an ideal amp/ speaker circuit where the speaker is the only part of the circuit with resistance, (no voltage sag possible; D factor=∞), the output power of the amp will halve when the load impedance is doubled (ohm's law). Amps operate much like this when powering higher impedance loads because their impedance is negligible relative to that of their load.
@jamesduty92 Once the amp begins driving lower impedances, however, and it's output impedance becomes significant relative to that of the load, it's voltage drop will too become significant relative to the voltage across the load. So while ideally halving load impedance should double current, (and therefore power), that the load sees, at a certain point it merely increases distortion significantly, and power only slightly. At this point efficiency is greatly reduced as well.
@jamesduty92 The minimum "ohm rating" of an amp should reflect the nominal load impedance where the most power possible can be "drawn" from the amp, keeping distortion, damping factor, efficiency, power consumption and heat buildup at acceptable levels, given the device's intended application.
now i don't really play with all the dampening factors and so forth,
i just know that power, ohms, and speaker wirings with amps and that is usually what works, i do know how the circuits inside work, with the power coil and capacitors, but other then that,
i have never had an issue with an amplifier unless im underpowering and i always now that will happen before i do it.
hello i have a crown xti 4000 and im using the to run my two JBL SR-X SERIES SR4719X but i have a question everytime i hook them up it feels like i get alouder sound from one side then the other side. can anyone help me how i can properly set up my subs so i can get a good sound out of my subs
it sounds like a problem with the volume control system, (ive heard that it happens alot and its just a cable from the board inside to the front DSP that causes the problem) contact Crown and they should be able to help out
Question. I have a xti2000 and want to use one side for my low(PV SP118 Passive 8 ohms 2400 w capacity). will it be able to handle the PV, and if it does will the other side handle my 2 tops(JBL JRX 125). HELP!!!
Hey there audiogod9000, If your interested in the crown XTI amps you will have no problems with them at all, takes a while to get use to how they work but if you want a amp that will work every gig, then the XTi amps are for you!!! And question you have on the xti amps please feel free to ask I would love to help you out, I run xti amps in my concert system, love'em Later Corey
im dien for 1 a these cause of how good they work and power they give. plus i have a subwoofer output and this amp would be perfect for it to put my subs on, strait bass, do you think a 1500W RMS technical pro sub would work good on this? and its 8 ohm, and i also got 2 10" audiobahns 300W each @ 4 ohm with 2 15" bookshelf speakers which are already setup good, pls respond?
at the momment i am actually running the 18" 2000W RMS technical pro subwoofer on around 400W and its absolutely pounds, so i can't imagine the bass it can produce if i actually put the 2000W into it, im running it off a Biema Q250 amplifier.
Wow, i only got like 300 W on 2 technical pro 15s and its unreal. please check my newest vids out, it shows the 2 15" TECHNICAL PRO SUBS in a custom u-port vented box, its crazy big, i get lows you'd never imagine, and like u said lol, on low power also!. they drop lows great, hit mid bass nice, and the high freQ bass will kill you lol, cya!
please help how good is the Crown-XLS-5000-Power-Amplifier thanks really appreciate ur help
