    Combining 8-Ohm and 4-Ohm Subs with PA

    OK, I ran both subs, each on its own channel on the QSC PLX3402. Set by ear, the 4 ohm Carvin was set at 2/3 what the 8 ohm Seismic was set at. I positioned both subs about 4 feet apart on the floor near center stage. We ran 4 15" mains at 2 ohms through the Mackie m1400i on one channel (two on...

    Which Amp for 8 Ohm, 1000 watt RMS 18" Sub

    Hi Bob, and thanks for the clarification. On another note, can the internal limiter even respond fast enough to a kick drum strike? In fact, I don't hear any distortion at all even when the clip light illuminates, with or without the limiter on. Does that mean that even though the clip light...

    Which Amp for 8 Ohm, 1000 watt RMS 18" Sub

    Just an update: I happened across a used QSC PLX3402 in very nice condition at a Guitar Center near me for $400. Darned cheap, given the market value for these used seems to be $600-$700. I am running the sub on one channel at 700 watts, and it is quite happy (as am I). In fact, I haven't...

    Combining 8-Ohm and 4-Ohm Subs with PA

    My mistake on the Mackie 15. You are right, I remember now that it was the current draw that was 350 watts. You're also right about the lack of "throw", but darned nice indoors, to be sure. Yes, the Seismic site says 90 lbs, but trust me, it is lighter. Seems lighter than even the SRS1500...

    Combining 8-Ohm and 4-Ohm Subs with PA

    The powered Mackie 15" I had previously only had a 350 watt internal amp, but it was a monster all by itself at indoor gigs, like bars and restaurants, etc. The 18" Active Mackie I had was only 800 watts, and it did well by itself outdoors, and we never had to run it at full power. But, at...

    Stereo Headphone Out to Mono to Stereo Headphones

    They worked. Thanks anyway! :-)

    Stereo Headphone Out to Mono to Stereo Headphones

    I don't need it to be stereo again. I just want mono in both ears. So, based on what you're saying that next adapter will essentially convert my IEMs into mono, so it should work. As a matter of fact, I currently use a similar cable/adapter to sum my MP3 player's or computer's stereo out into a...

    Stereo Headphone Out to Mono to Stereo Headphones

    I want to be able to monitor the live mix, a recording mix, a monitor mix, and a subgroup. I would listen to the the three mixes separately, and mix in the subgroup only when listening to the monitor mix. Right now I am doing it via a Mackie 16-channel that is being used as a pre-amped...

    Stereo Headphone Out to Mono to Stereo Headphones

    I want to use one stereo channel for two different sources, each of which I will listen to at different times by panning one way or the other, but I want to hear each source in both sides of a pair of stereo headphones. Can I just plug this: Invalid Link Removed into this: Invalid Link...

    Combining 8-Ohm and 4-Ohm Subs with PA

    Hey, I'm just exploring all avenues, but your point about us already bringing the extra sub is well-taken. We might as well bring the other amp. :-)

    Combining 8-Ohm and 4-Ohm Subs with PA

    OK, the Carvin sub is indeed 4-Ohms. I daisy-chained it with the Seismic 8-Ohm, and I gotta say they sounded great together. Yes, the Carvin was louder, but it sure did not seem to be 2/3 louder. I put a 50 watt L-pad I already had in-line with the Carvin to attentuate the volume a bit, and we...

    Combining 8-Ohm and 4-Ohm Subs with PA

    While I could do that, I really don't even want to have to cart the second sub. :-) And, we may not even need to, if it's going to be a hassle. I wasn't even thinking about a second sub. It's one of those things that because I know it's available, I want to see if it's a viable option. You are...

    Combining 8-Ohm and 4-Ohm Subs with PA

    It is a Seismic Audio Enforcer II. I know they get a bad rap for being so inexpensive, but I used to have a powered Mackie 15, and honestly, this Seismic Audio sub sounds better outdoors than the Mackie did. We then tried a powered Mackie 18 and while it sounded good under a tent, it was only OK...

    Combining 8-Ohm and 4-Ohm Subs with PA

    We are a local 200 mile radius variety cover band. I have plenty of amperage between my QSC, Yamaha and Mackie amps. I've been scaling back so I don't have to deal with the weight of that Mackie, and dual subs, so the single 1000 watt sub is all we typically run. The QSC I have is the PLX3402...

    Combining 8-Ohm and 4-Ohm Subs with PA

    Not sure what you meant by that. I am trying to keep the 2nd channel open, which is why I am exploring this. OK, so I would end up converting that 8-Ohm speaker to 4-Ohms, but: Let's say there are 700watts output to one 8-Ohm speaker, but there are 1800watts total output to a 2-Ohm-ish load...
