2 Ohm Tekton Pendragons
Talk to @atmasphere. He will tell you how lower impedance = more distortion. The question is always how much (will vary by amp) and is the distortion pleasant sounding or not. One thing for sure you will likely be advised to NOT use Atmasphere amps with those if truly a nominal 2 ohm load and especially if any kind of response down to 20 hz can be delivered as advertised. 2 ohms will make any amp work harder than if higher. That is a fact. It’s best to make any amp not work harder than necessary. MC is just plain wrong when he says high efficiency means any amp will do. Not the case if these are in fact 2 ohm speakers with flat response down to 20hz. BAss is where an amp must work hardest to deliver. The lower the frequency, the harder it works...exponentially. I would anticipate at best running true 2ohm speakers well off most any amp means limited and distorted bass. But you never know for sure till you try (and measure) as they say... Offering a product advertised as 2 ohms tells me Eric is mainly interested in being able to toss a variety of bait (various speaker models with various differences) in order to catch the most fish. Nothing wrong with that. It is what it is. I suppose there is a unifying design approach to them all. The tweeter arrray I suppose. Tweeters are not nearly as hard to drive well as bass drivers. Much less work involved.......exponentially by frequency. |
Hey Miller - I have a pair of Impact Monitors (4 ohm) on order. So to an extent you are preaching to the converted. I have an amp that will cheerfully drive a nominal 4 ohm load all day long and is stable into 2 ohms. I'm not questioning Eric's technical chops at all. But from my experience working for a consumer amplifier manufacturer and having represented several others in the business, I know for a fact that those circuit designers are not typically expecting their customer to be driving speakers with a 2 ohm nominal load - especially since that "nominal" impedance implies that the actual impedance dips lower than that. Now the engineering team at Crown or QSC, etc. have a different mission. My question is what consumer-positioned brand makes an amp circuit that is happy at 2 ohms and lower? That's all. Mapman: Yup see the link here: https://tektondesign.com/product/full-range-speakers/full-towers/pendragon-2-ohm/#color I'd certainly call the company and ask someone for an amp recommendation before placing the order. But I am curious to hear how the 5-driver array sounds like compared the 7-driver setup. |
2 ohm? Really? Interesting. Personally I’d let others try those first. Or just take advice from those with simple and biased views of how things work just because and try it for yourself. I’d be interested to hear out it works out. Also some measurements to back up the published specs which are very loose as published to start with. |
What puzzles me is the obsession with impedance. When the speakers are 98dB sensitivity, how much current can it possibly take??! Also if you do want to talk impedance, try listening to Eric. Learn that low impedance is actually desirable and yields better sound. Some of his designs like my Moabs can be ordered in 8 ohm version. All the gear heads on this site urged me to order them, swore they would sound better than 4 because, tubes. Current. BS. While on the other hand, every time I point out the irrefutable fact that low sensitivity speakers are hard to drive, people come out of the woodwork skirts over their heads in a tizzy. Like we don’t all know low sensitivity requires tons of watts and current. So even though this is all patently obvious I do not expect it to catch on any time soon. We live in an age of superstition. Believe what you want. Buy em or don’t. Puzzle away all you want. Me, I have a fantabulous sound system to build. See ya! |
