Members solderjunkie Posted January 18, 2009 Members Share Posted January 18, 2009 How can a 610 cab be wired to end up with 4 ohms or 8 ohms... All the "big companies" offer a 610 either in 4 or 8 ohms. I'm missing something obvious, aren't I? I can't wrap my head around the math of this (It's the dividing by 3 that's getting me).

They use drivers with a different impedence than those in their 410s or 810s... - georgestrings Link to comment Share on other sites More sharing options...

I've only seen 4, 8, 16, or 32 ohms available. Are they offering a different impedance that those? Link to comment Share on other sites More sharing options...
Members bassman1956 Posted January 18, 2009 Members Share Posted January 18, 2009 What if:4 drivers @ 8 ohm, 2 drivers @ 4 ohm, 2 lines with 2 8-ohm speakers in series = 16 ohms each line1 line with 2 4-ohm speakers in series = 8 ohms that line put all 3 lines in parallel,add the reciprocals:1/16 + 1/16 + 1/8 = 1/4the reciprocal of that = 4 total load = 4 ohms Is this how it's done?

Although I haven't physically verified it - mathematically, I'd have to say it's so... If I have to get into my 610, I'll let ya know what I find in there... - georgestrings Link to comment Share on other sites More sharing options...
Moderators Kindness Posted January 18, 2009 Moderators Share Posted January 18, 2009 24 ohms in parallel for a 4 ohm cab. Link to comment Share on other sites More sharing options...
Members Bryan316 Posted January 18, 2009 Members Share Posted January 18, 2009 Ampeg SVT610HLF The top four speakers are each 8 ohm drivers, wired in series-parallel, for an 8 ohm load at the top. The bottom two speakers are 4 ohm drivers, wired in series, for an 8 phm load at the bottom. The top and bottom are wired together in parallel, dropping it to a 4 ohm total load for the whole box. The SVT610HLF is known for blowing the bottom two drivers because of uneven wattage distribution. The ONLY 610 I'd trust is the Eden D610XLT because they wire six identical drivers to get a 5.3 ohm load. No single speaker gets more than another. And I have heard of folks rewiring it to get a 2.67 ohm load for those amps which handle dropping to a 2 ohm load. Not sure how the circuit would look for that though. I think it's taking three pairs of serial drivers and paralleling the three pairs together. Or a unicorn. Not sure. Where's my coffee... Link to comment Share on other sites More sharing options...
Members collinwho Posted January 18, 2009 Members Share Posted January 18, 2009 I don't know, but on a similar note, I bought three beers last night and it cost me $8. How the hell does that happen? If I only bought one were they really going to charge me $2.66 for it? Link to comment Share on other sites More sharing options...
Members poomwah Posted January 18, 2009 Members Share Posted January 18, 2009 so if you were to wire up six 8 ohm speakers, you would get 5.3 ohms? I've been wondering about this since I have a 410 and a 210 I'd like to wire together but wasn't sure what it would do to the amp running "in between" resistance. It lists the output at 4 ohms and 8 ohms. Its still safe to run anywhere in between there as long as I don't drop BELOW 4 right? Link to comment Share on other sites More sharing options...
Members rpsands Posted January 18, 2009 Members Share Posted January 18, 2009 I want to say they often use 6 ohm drivers for 6x10s (getting to either a 4.5ohm or 9 ohm load?), but that's just a vague recollection. Link to comment Share on other sites More sharing options...
Members james on bass Posted January 18, 2009 Members Share Posted January 18, 2009 IIRC, Epifani & Markbass claim 6 ohms for their 6x10s. Link to comment Share on other sites More sharing options...
