G-K / Guitard Center Question

JVA · #1 08-27-2011, 11:34 PM

I needed to replace 2 speakers in my G-K 410SBX. I ordered a pair of Eminence Legends (there was a thread on this already...) and the consensus was to replace all speakers with the same brand, being Eminence. I had bought a pair a few weeks ago and last week I ordered the others. Today I had a chance to install them, but I have a problem:

The speaker on the left I bought first, the speaker on the right is from this week. The speakers are different! The one on the right has a double-cone.....

The one on top, which is this weeks purchase, has a much beefier magnet and a rear facing port of some sort in the center. Both boxes are marked as the same, but obviously they're different. Can anyone tell me which one is right? The ones from this week are marked as 8 OHM while the others have no OHM listed. That's the only difference I see on the box.

I need information so I can convince GC to exchange 2 speakers to match whichever ones are right. HELP!

Call GC for your answer. Tell them you need 4 matching speakers or they will get these all back.

I was hoping for a little more information other than going back to Guitard Center, where the foul-up happened.... with a bit more ammo as to which is the correct speaker for my needs.

Second shout: Anybody have an absolute answer for when I go back? Which speakers are the correct ones?!?

Probably neither. You should have contacted G-K to get the correct replacements.

Why not contact GK or Eminence and ask what they suggest?

Windreaper · #6 08-28-2011, 08:28 AM

Without knowing the specifics: if it is between the two speakers pictured, you will want to use the model without the whizzer (double) cone. So, the speaker on the left. Optimally, you might want to return the speakers and order replacements from GK.

EDIT: D'oh, Bill beat me to it. Get original speakers from GK since the specs are bound to be different.

Eminence makes OEM speakers for GK. They are not the standard offerings on the Eminence website. You have to go through GK to get the precise replacements. Return the one you ordered for a refund if possible and ask GC to order replacements for you (OR another GK dealer).

Judging from the Eminence website, the one with the whizzer cone is a Legend B102, and the one without is probably a Legend BP102. The BP102 is the one that I have more typically seen associated with bass guitar use.

I doubt that either is a perfect match to what's in the GK cab. GK does sell replacement drivers, and the prices that I've seen are not exorbitant.

I had to replace speakers in my 410 sbx when i had it and i can tell you unless you know more about wiring than i do that 8 ohm speaker will not work.You will need to contact GK and get the proper 32 ohm speakers,unless you can wire four 8 ohm ones in a way to still make it an 8 ohm cabinet.

If I had to guess I'd say they sold him Legend B810s which are 32 ohm speakers (and thus suitable replacements in that sense). Still, no reason whatsoever not to get original replacements from GK.

Four 8ohm speakers can be wired in series/parallel to present an 8 ohm load to the amp. Wire a pair in series (will make a 16 ohm load), repeat for another pair, and then wire the two pairs in parallel, and viola! you have an 8 ohm load.

I am absolutely clueless when it come to wiring!!

You can order replacements direct from GK. They are between $85 and $130 depending on the speaker.

That's what I was thinking!

Probably, and the model names being so close explains why both the OP and G-C thought they were the same. Of course neither is a replacement for the 32ohm G-K driver.

JVA · #18 08-30-2011, 04:22 AM

I'm so happy G-C screwed up and ordered the mis-matched speakers, which led to me posting about it. Because of this I learned that my G-K cabinet has 32 OHM speakers and more than likely I would have killed my amp using the four 8 OHM speakers! Last night I returned the speakers and bought a set of B810's, which are the 32 OHM direct replacement speakers for my cabinet. And it cost less too! Now I'll re-cone my original speakers and hunt for an empty 4X10" cabinet.

Thanks for everyone's input, you guys helped save my rig!

This

Just throwing 410's in an empty cab that isn't designed for those speakers is a crap shoot at best.

Wes Whitmore · #20 08-30-2011, 05:38 AM

If you were going to recone the drivers anyhow...why didn't you just do that in the first place? B810's might be 32 ohm, and they might work in the 4ft sealed box of the sbx, but they wont sound the same as what you took out. Reconing with original GK parts, or getting GK speakers designed for that cab is the only way to get the same sound. Finding older model replacement speakers is tough on the wallet when you can find that sbx cab for $250 in working order on the used market, and you get spare speakers.
