Raslee Posted July 19, 2008 Share Posted July 19, 2008 Hi folks, i've got one of these old Eden WT800 amps and weirdly the minimum load is 8ohms for 800 watts, it doesn't take a sinle 4 ohm other than 4ohms a side (2 channels). So anyhow i am looking for an 8x10 (Ampeg, Ashdown etc)....anyone know of or heard where i can get an 8 ohm.....alternatively i already have an ampeg 4x10 4 ohm....if i was to say purchase another Ampeg 4ohm how would i wire it to become 8ohms....please forgive my electrical dyslexia. Thanks Bass brethren Quote Link to comment Share on other sites More sharing options...

Thanks Bass brethren[/quote] The short answer is no. Any you wont be able to rewire one from 4 to 8 ohms. The obvious answer is to run 2 4 ohm 4x10 cabs, one to each 4 ohm stereo output, and make an 8x10 in instalments. Even more so as you already have 1 4 ohm 4x10. If you don't know how to use it, why buy such a specialist amp? Just highlights the dangers of buying amps and cabs separately without thing about how they are going to work together.

SteveO Posted July 19, 2008 Share Posted July 19, 2008 the slightly longer answer is yes. two 4ohm cabs in series will give you an 8 ohm load. if you're handy with a soldering iron and have a small box, 3 mono jack plugs and about 10 inches of appropriate wire then you'll be able to knock up a small patch box in 10 mins that'll save messing with the insides of the cabs. can't see why an 8x10 would be anything other than 8 ohms. assuming using 4ohm drivers... (this may be a BIG assumption, it appears to me that most cabs use 4 ohm drivers, but I may be totally mistaken about this)... then how would you wire it to be a 4 ohm cab?

SteveO Posted July 19, 2008 Share Posted July 19, 2008 Ok, I'll admit i'm wrong. It appears that they use 2 ohm drivers when building 8x10's as most punters want 4 ohm loads. however there are 8 ohm 8x10's out there...

(plus you can use just one cab when your back starts complaining ) Quote Link to comment Share on other sites More sharing options...
bnt Posted July 19, 2008 Share Posted July 19, 2008 (edited) You're right if this is the original WT800, and not the WT800B - I just checked the [url="http://www.eden-electronics.com/info/manuals/pdf/WT800-600-500manual2003.pdf"]manual[/url]. The 8Ω figure is for when you run the amp in Bridged mode, but (as you say) you can run 4Ω per side in Stereo mode. So if you were to buy another 4x10 4Ω cab, and plug it in in Stereo mode, there would be nothing to rewire. PS: 8x10 8Ω cabs do exist e.g. the [url="http://www.mesaboogie.com/Product_Info/Bass_Cabs/RoadReadyCABS/RRbass8x10-LG.htm"]Mesa Boogie[/url] can be had in 8Ω or 4Ω.

I tend to do that Still, I wouldn't say that wiring three jack plugs and three pieces of wire into a triangle, then sticking it into a box is complicated, and doesn't justify the "all that" label so unfairly allocated by your good self [flounces off to watch TV] Quote Link to comment Share on other sites More sharing options...
Raslee Posted July 20, 2008 Author Share Posted July 20, 2008 cheers for the advice guys. The Eden was passed onto me btw, so there you go. I think i may well do the series wiring, just checked up on ohms law and it looks fairly straight forward and ting. Just got in from a lovely gig right on sea front and my eden was pumping the riddims.....was so nice to play reggae in the sun, been given free lobster too and some lovely cocktails called Cosmopolitans! To the guy who said by a combo, lol...i already have some Ashdown in my living room....need big rig for the road dread, seen! Soon with 2 x 4x10Ampegs IRIE Quote Link to comment Share on other sites More sharing options...
bass_ferret Posted July 20, 2008 Share Posted July 20, 2008 You dont need to do no ting. All yo need is connect 1 4ohm 4x10 to 1 4ohm output, and another 4ohm 4x10 to de udder 4ohm output. Job done and roll one IRIE. Never thought of 4x10's as reggae cabs. Quote Link to comment Share on other sites More sharing options...

Yes dready, most major players backing Sizzla, Capleton, Luciano etc are using the fridge (Ampeg 8x10)...I was fortunate to briefly meet and see familymans rig last year at Lanhydrock (makes a good alternative lyric on trench town rock btw) and he was using an eden 4x10 and ampeg 15" and an Eden WT800 bit like mine...a lot of the old school used to use the 18" and 15" but perhaps as much as 90% of modern players are using the Ampeg 8x10 nowadays with Familyman being the main exception....but then if it sounds good who cares, my 4x10 on its own is nice but i need a bit more air for the larger venues and stuff ....but most of our sound goes through our 11K sound sys anyhow and that only ever runs at about half for most clubs/venues etc. So to keep up with our drummer (Roland TD20 or something top of the range electric banger type thing) as its his sounds sys i need a bit more air on the backline....if you can't feel the riddim of the bass in the belly then well.....plus i kinda like it myself too....irie fe sure!

bnt Posted July 20, 2008 Share Posted July 20, 2008 Well, the 2nd cab doesn't need to be a 4x10. It can be a 1x18, as long as it's 4Ω. If I was seeking Dub, I would want the deep fundamentals, mon. Righteous. Quote Link to comment Share on other sites More sharing options...

We are talking 'bout Dub, here. Quote Link to comment Share on other sites More sharing options...
bass_ferret Posted July 20, 2008 Share Posted July 20, 2008 The same applies to whatever cabs are being mixed - size does not matter. Putting the same signal through different sized cabs can lead to unpredicatble results. Quote Link to comment Share on other sites More sharing options...
