1 Speakon or 2 1/4"??

    I'm about to purchase an Eden WT-550 amp and two of the Epifani 110s and was curious about hooking them up.

    The amp has two 1/4" jacks on the back but apparently only one speakon jack. I keep hearing speakon connectors are better, but is this really a better setup if there's only one jack??

    As is, you can only run one speakon cable from the amp and it would seem like a large load would be going through it to the first speaker; the speakon cable then going from that speaker to the other would thus be carrying a smaller load.

    Again, is this preferable to two separate 1/4" cables going from the amp to each cabinet? For that matter, would it not have been smarter to just put two speakon jacks on the back??

    Also, if I do go the speakon route, would daisy-chaining them in this manner still produce a 4 ohm load? (Both cabs are 8 ohms each and while I know that would produce 4 if they were wired separately, I didn't know if it would still = 4 daisy-chained.)

    Thanks for your help.

    what you do is just use 1/4". It would make your life a lot simpler. When you "daisy-chain" speakers, it is running in parallel mode. There is no less power going through one cable or the other. If the cabs are the same impedance, they will both take half of the power. Don't worry about speakons if you can't capitalize on their benifits. Try like in the diagram with 1/4" speaker cables.

    if you have the cash, go with the speakon. they will never fail on you. theoretically they can transfer more power through the connector if the gauge(thickness of the actual cable) allows it when compared to a standard 1/4" connector. even though there are 2 1/4" jacks on the amp the same amount or less of the one speakon simply because of the gauge of the cable. they claim that at high volumes, the speakon cable can give better low end and eliminate unwanted noise from the transfer of the amp power to the cab. i used to use 1/4" until i got a salesman to through in a speakon cable when i did a major purchase, now thats all i use for my ampeg rig.

    you could put speakon in the amp, but obviously 1/4" on the speakers.

    Why would you do this with 1/4" when you can do the *exact same thing* with Speakons?

    You still get a normal 4 Ohm load (assuming two 8 Ohm cabs), and you get the all the benefit of the Speakons, too - locking, higher current capability, more durable, no shock potential. Using 1/4" in this diagram, you're putting all your rig's current through one 1/4" jack! Of course, this assumes your Epis have a pair of Speakons each.

    BTW, good call on the WT-550. I picked one up about a month ago to replace my preamp/poweramp rig into my pair of Bag Ends, and I like it a lot!
  6. A 1/4" phone connection can be depended on to reliably pass 250 watts. A Speakon is good for 1000. Aside from that, if someone trips over your Speakon-connected cable, they'll probably pull your rig to the floor before they disconnect it. If you try to pick up your amp before unplugging, the speaker will come off the floor before it disconnects.

    Sorry if I'd left details out about the Epis: they do have 2 speakons on each cabinet as well as one 1/4" input...and again, the amp has two 1/4" outputs but only 1 speakon.

    I think, since we're only talking 500 or so watts (and I likely will never have it turned up more than halfway) that I may just go with two 12-gauge 1/4" to 1/4" cables. They'll only be 6-feet each so I'm sure that would be fine.

    In truth, I do actually worry about Speakon plugs locking into things. Personally, if someone trips on one of my cables I'd rather have it pop out of the back of the amp or speaker as opposed to possibly pulling the amp over the edge or ripping the connectors out. Maybe a silly concern but who knows.

    Thanks for all the advice.

    just use speakons, then. Keep your cables shorter, though. Then you won;t have any problems. I thought the speakers had on 1/4" jacks. Run all speakons. It's more dependable. I've killed a few 1/4" cables by steppin on the cord and bending the tip off. Speakon is your best bet in this case.

    A 1/4" speaker cable getting yanked out of its jack might fry the amplifier.

    If you make the speaker cables only as long as is needed, you will get better power transfer and there won't be loose cabling lying around to trip over.

    I would use the Speakon output on your amp and chain the two cabs just like the aforementioned diagram ('cept with Speakons).

    My speaker cable is three feet long; it never even touches the floor.
  11. are there any advantages of speakon-speakon over speakon-1/4 in.

    the cabs i'm looking to get (avatar) do not support speakons but the poweramp does

    The only disadvantage with 1/4" connectors is the contact area is not very "high power" friendly. Real world situations 1/4" are probably OK, unless your pumping a whole lot of watts through them.

    You can use a Speakon at your amp end and a 1/4" at the speaker to get the most out of what you do have.

    I use a banana connector at my amp (at the moment) and a Speakon at the cab. Bananas are better than 1/4"'s but still not as good as Speakons.

    [I'm running 1600W through mine though. Eventually, plan to replace the banana with Speakon.]
  13. what exactly happens if too much power goes through a 1/4 inch.......nothing too technical please :D

    I am not sure, but I would assume that the number of electrons attempting to flow through the contact area would be greater than could be accommodated by that small of an area and it would start arcing (sparks between adjacent metal surfaces) like an arc welder.

    I have no idea how much power that would take though or how much of a hazard that might be (doesn't sound like a good thing though).

    Do we have any electrical engineers listening out there?

    Hey guys:

    I currently own an Aguilar GS410 and I'm planning on buying 2 Aguilar GS112's. They are meant for two seperate ocassions, the small gigs and the medium sized gigs, but for those large gigs...I'd like to combine all the cabinets together. I'm planning on getting a QSC PLX1602, which can run a 4 ohm load to each channel. I desire using the Speakon connectors at the back of the QSC and the Aguilars have connectors at the back of them, but the problem is that they only have 1 speakon connector on the back, and that is an input. My question is if I run my 2 GS112's with a Speakon Running to the first 112, how am I supposed to continue using the Speakon efficency to the next GS112, since there is only a 1/4" out. If there are any other ideas, please let me know. Thanks guys. If this made no sense, please let me know and I will clarify.

    Either find or make a Y connector cable (one Speakon on one end splitting off to two Speakons on the other end) to run off that one side of the amp. Otherwise you would be stuck using a 1/4" to Speakon (or 1/4" to 1/4") to chain to the second GS112.

    "A 1/4" phone connection can be depended on to reliably pass 250 watts."

    I'm just curious. What exactly are you basing that statement on?

    There are any number of amps and speakers with 1/4" connectors that are rated at MUCH more than 250 watts that have been running without problems for years. I'm talking about highly respected, major brands like SWR etc.
