    Hi gang, Not much of a DIY-er, but I am putting a new Eminence driver in an old extra SWR cab I have. The existing driver (4 ohm, when the cab was originally 8, which I need it to be) has clips, so I figured no problem.

    But there is a problem: the Eminence has two different size clips, the hot being slightly smaller than the ground. (Existing wires have same size.)

    So should I: a) get one larger clip and replace the one on the hot wire or b) cut off both clips and just use solder? (Or get a new hot clip and add solder to both anyway...)

    All expert thoughts appreciated...

    I think solder is a waste of time. The clips work fine as long as they're not all worn out. I'd go clips.

    Do not solder, just get the right size connector. Most are the same (.187") rare that they are different. Have you measured them?

    Yes, the tabs on the new Eminence are DEFINITELY different size, maybe only a mm or two but it's visually obvious.

    There are standard sizes, measure and compare. The most common are .250" and .187"

    Yup, that's it. The ground tab is .187 and the hot is .25.

    So I guess I'll need to get the .25 clip, and solder onto the wire. So, I'm soldering anyway...oh well.

    The reason for avoiding soldering directly to the tab is to avoid damaging the compression connection that the tinsel wire makes with the tab. Is this a stock off the shelf Eminence speaker or is this some OEM type?

    Also, you don't need to solder the connectors to the wire, a proper crimp tool is a better way to do this, and how ALL of the manufacturers assemble their cables.

    Ah good, just crimp it to the wire.

    This is a stock Eminence driver, Legend BP1525. I guess they just put different size tabs on hot vs. ground.

    Gracias, Caballo...PS: GB support: are you in AZ? Oh wait, I see you're in Davis...

    Very interesting, the docs I have (pretty early open stock product) show .187 for both tabs. I wonder if they were changed in the MI line to eliminate the possibility of miswiring? All my service terminal boards are .187 for both tabs as well.

    Note that there are 2 thicknesses of tabs, the speaker products use the thinner tab, so you may need to squeeze the female connector down a bit if you have the thicker females. The thinner ones are somewhat specific to the speaker industry.

    If the cab has a Neutrik speakon with fastons (those spade connectors), this is the size: NLFASTON - Neutrik (0.187" x 0.02").

    Eminence has changed their spade connectors on some speakers, see below. For Eminence OEM, I've used TE Connectivity 0.205" (Eminence Speaker Components).

    LOL, well it's an old SWR box from probably 90s or early 00s, so no speakons! But still in good shape, the tweeter's fine, new Eminence will be perfect for my needs (extra cab off of my Markbass Jeff Berlin, when I need more volume...)
