Members Jateca Posted July 3, 2005 Members Share Posted July 3, 2005 Hi, I need a bit of advice for choosing a cab. I've decided on the Peavey 4x10 TVX cab after I've read some good reports from this forum about it. Problem is though, that the cab comes in 4 ohm and 8 ohm models, and I'm not exactly sure which would be best in the long run to get. I've got three heads in mind, a Laney R4H, an Ashdown MAG 300 and a Hartke HA3500. These three all deliver around 300-350 watts at 4 ohm. Would there be any reason for me to get the 8 ohm version cab over the 4 ohm version, or is the 8 ohm designed for amplifiers with a minimum imperdance of 8 ohm?

Members timmerz Posted July 3, 2005 Members Share Posted July 3, 2005 Jateca, be careful of the Hartke HA3500....It doesn't want 4 ohm speakers, if you look on the back of the amp it has 8-ohm markings over both of the speaker out jacks...My 3500 timed-out a couple of times when I first got it, before I realized what was going on, and traded my 4-ohm cab for an 8-ohm, then bought another 8-ohm to use also....I can't speak for the Ashdown or Landey (never heard of that one, unfortunately), but I'm sure someone else will chime in to help you out with those...

Damn, sorry I meant to type LANEY. Cheers though, that does answer my question nicely. If I go for the Hartke, then I'll get the 8 ohm, for the other two I'll get the 4 ohm. At the moment I'm leaning towards the ashdown, but it's a bit more expensive than the laney Link to comment Share on other sites More sharing options...
Members timmerz Posted July 3, 2005 Members Share Posted July 3, 2005 Just keep in mind that the 3500 at 8 ohms is developing about 200rms, if I remember right.....you'd need to run 2 cabinets like I did to get it to achieve it's full 350 rms.....

Thanks I will. It might even be a good excuse to get a 1x15 cab to go with it:D Link to comment Share on other sites More sharing options...

A lot of amps have both speaker jacks labled "8ohms". That just means if you're going to use two cabs they must both be no less than 8ohms each. There's enough other stuff to keep me away from Hartke, (bad solder joints, flimsy controls, cheap input jacks, etc.) but I've never heard any problems about them being stable into a 4ohm load.

Members hammer744 Posted July 3, 2005 Members Share Posted July 3, 2005 Also, check to see what the minimum impedence is for any of those heads. Not many will go down to 2 ohms. If the minimum on the head is 4 ohms, and you buy a 4 ohm cabinet, you're done - you won't be able to add a second cabinet (like a 1x15, etc) if you want to enhance the sound. Any of the heads that put out 300-350 at 4 ohms are likely to be around 200-240 at 8 ohms. If you think you may ever want to add a second cabinet, then get the 8 ohm. If you think a single 4x10 will do you, then get the 4 ohm to maximize your output. Link to comment Share on other sites More sharing options...
Members timmerz Posted July 3, 2005 Members Share Posted July 3, 2005 Mudbass, I stand corrected....just went to the Samson site to review the specs (something I should have done a long time ago) and the specs say the jacks on the back of the 3500 are good for 4, 8 or 16-ohm cabinets. If that's the case, why the fok do they label "8 ohms" beside each quarter-inch speaker output, if they're giving everyone the freedom to plug in 2 4-ohm cabinets? Makes no sense to me! Anyway, my story is true: when I first got the HA3500 and was running it with a PAS 2x10 at 4-ohms and playing relatively hard, the amp would time-out for about 2 minutes at a time, so I took it in to a tech here in Livermore, who convinced me I needed 8-ohm speakers, and I never had another problem with that amp, all the way to now, 5 years later....
