StraightSix Posted December 18, 2011 Share Posted December 18, 2011 I need a little technical advice if possible... I have an 8ohm 4X10 cab and I would like to push a little more air and make use of the full power from my amp head so I was considering adding another 8ohm 4X10 but, in reality, I don't think I can get it all in my car. I then started reading about 6X10 cabs but they seem mighty heavy. So my question is - will it be a useful improvement if I add a 2X10 cab to my 4X10...? I realise that most 2X10 cabs are 8ohm which will mean the drivers in the 2X10 would be working twice as hard as the 4X10 but I was considering rewiring the 2X10 cab to 16ohm so each of the six 10" drivers are equally sharing the load. I think I have the maths right but I'm wondering if this will give a decent improvement or should I stick to my original plan of adding another 4X10 and get a bigger car...? Cheers for any help.

lollington Posted December 18, 2011 Share Posted December 18, 2011 Sell your 8ohm cab, buy a 4ohm 410 cab and keep your existing amp and car! Quote Link to comment Share on other sites More sharing options...
chris_b Posted December 19, 2011 Share Posted December 19, 2011 [size=4][color=#222222][font=Arial]A 4 ohm 410 won't “push” much more “air”, but adding a 210 to you r existing 410 will.

If I assume it is 500 watts then that's 250 watts per cab. You probably won't be playing flat out so let’s assume 250 watts, that's 125 watts per cab. The reality is that the 210 won't be working twice as hard; the 410 will be working half as hard.

chris_b Posted December 19, 2011 Share Posted December 19, 2011 [size=4][color=#222222][font=Arial]I wouldn't get into rewiring cabs. Any benefit is pretty slim to running them as originally designed.[/font][/color][/size][color=#222222][font=Arial][size=1][/size][/font][/color] Quote Link to comment Share on other sites More sharing options...
Mr. Foxen Posted December 19, 2011 Share Posted December 19, 2011 If you get a 8 ohm 4x10 and a 16 ohm 2x10 with same speakers and equivalent size (as in half), then you get equal power to each speaker, which is kind of important. Quote Link to comment Share on other sites More sharing options...
StraightSix Posted December 19, 2011 Author Share Posted December 19, 2011 Thanks for the replies. lollington - that had crossed my mind but as stated by chris b, it won't push more air. Mr Foxen - that is exactly as I had thought which is why I was considering a 16ohm 2X10. Would you consider adding one would be beneficial (obviously, I will gain something just by getting more headroom from the amp) but is this going to give a decent improvement...? Incidentally, the amp head is rated at 250W into 4ohms. Cheers Quote Link to comment Share on other sites More sharing options...
Bill Fitzmaurice Posted December 19, 2011 Share Posted December 19, 2011 Pushing air isn't about the number of drivers, it's about their displacement. Keep the car, get a high displacement Barefaced. Quote Link to comment Share on other sites More sharing options...

But the nicest thing is the modular 2x10, 4x10 or 6x10 setup you'll have. Quote Link to comment Share on other sites More sharing options...

I think you might get more "poke" out of the 410 if you just upgraded to a more powerful amp.[/size] Quote Link to comment Share on other sites More sharing options...
Lozz196 Posted December 19, 2011 Share Posted December 19, 2011 I`m not very good on the technical stuff, but I had an Ampeg 410 and 210, both 8 ohms, connected to a 500 watts at 4 ohm amp. For practice I just used to use the 410. At gigs, adding the 210 made a world of difference. Not so much in volume, as I kept that the same, but the "size" of the sound. Probably helped being that bit higher up too. Quote Link to comment Share on other sites More sharing options...
ead Posted December 19, 2011 Share Posted December 19, 2011 I used to have a 1x15 and a 2x10 Ashdown rig. This had now become a 1x15 Barefaced Compact rig which sounds pretty much the same in terms of "volume" and weighs 12kg compared to 56kgs for the two Ashdown cabs and occupies approximately 1/3 of the space in the back of my estate car. It's also cleaner and much more defined tone across the whole range. I'm awaiting delivery of a second cab, not because it's necessary to keep up with the two guitars, but because 2 Compacts will be be an awseome combination! The BF Sper 12 might be worth investigating, but get in touch with Alex at BF who is completely brilliant at customer service. Quote Link to comment Share on other sites More sharing options...
StraightSix Posted December 19, 2011 Author Share Posted December 19, 2011 Many thanks for all the suggestions - I have been considering a BF cab so that may be the ultimate route. I now have lots of ideas to chew over... Quote Link to comment Share on other sites More sharing options...

brensabre79 Posted December 19, 2011 Share Posted December 19, 2011 A 4 ohm 4x10 would get the most out of your amp without adding extra cabs. You're probably getting about 150w max running at 8 ohms. However watts isn't everything as people have said. If you can afford a BF cab Alex is super helpful, and there's lots of good info about watts and cabs etc. on his website too. If not I'm thinking of selling my SWR 4ohm 4x10 very soon...
