2 Ohm Tekton Pendragons

Easy peasy.. Hypex NC500 will drive them no problem..  If they are wired at 2 ohm, no idea on that one. I wouldn't, especially for a full range speaker.. limits the choices.

That is a class d amp speaker plain and simple.. 2 ohm stable A/B way to expensive. Class d for sure.. 1000.00 will drive the neighbors out for sure.. BUT 2 ohm? WAY to much distortion and the lower you go the higher it goes.. 8-16 ohms is still preferred for mids and highs.. 

Especially valve amps.. Night and day on small planars or ribbons when they are driven at 4 opposed to 16 ohms.. Just very clean at 16 ohms.. 
The tech side is "better bandwidth". The same reason I like valves for low mids, mids and highs.. They just work better there.. 

98% what on earth are they used for PA? How do you get 98% domes?
You better not have ANY noise in a system... That is really pushing it..
I think the 98% is a bit hype... I'd have to see the numbers on that one and how they came up with them.. They just don't work...

With todays amps and the headroom available for the dollars.. WHY? 2 ohms?

LOL not at 2 ohms MC it just won't happen with a valve amp. A Mac will do 2 ohms in series or paralleled. BUT only in mono. At 4 ohms in mono they sound OK at best.  2 ohms, you could fry eggs on it.. I have no doubt.. The older MC275 get HOT.. @ 8 ohms.. Every Mac I own runs better at 8-16 ohms.. same power, little difference from 2 ohms to 24 ohms, same wattage or very close.. They just sound better, because of the bandwidth, and distortion.. They run 1/2 the heat index too, @ 12 - 16 ohms. Tough to beat a MC240 all dolled up.. They really don't like 4 ohms.  HOT!!!!

If they are like most bass section, they will go from 2-22 ohms without some type smoothing. Phase shift of that magnitude from a bass driver is demanding enough. BUT below 2 to over 20 ohms @ 2-400 hz. That is the reason for the bloated bass a lot of tube amps have.. The fact that they ARE doing bass duty and have a swing in load.. Load demands and quicker response from a power supply (hexfred) make a big difference..
BUT relieve the valve amp bass demands and it just works BETTER in the mids and highs.. 2 ohms though.. on a valve amp is just a NO NO..

In an automotive application it’s not uncommon to see 1/2 ohm loads to PUSH an amp.. BUT have you seen what it takes in cable size? IT’S JYNORMUS. A lose connection is a fire.. Have to TORQUE the lugs, AND you better use a contact enhancer for the power supply.

Home use, you better keep the connection tight to @ 2 ohm, too. STUFF will get hot... Not a question of that.. Class D get hot too.. HOW HOT?
They will MELT and talk about STINK...

 VAC could theoretically be a solid match.

They might push the load, BUT they don't like the load.. Mcintosh is the same way.. 2 ohm loads though.. sound BAD on a Mac.. Just a fact..

To have GREAT bass from 2R speakers, you will need 8 runs of AWG10 speaker cables to feed it... or, if you want to simulate my setup in a 2R scenario, then it’s 16 pairs of cables!

I don’t think so.. Your leaving out the only part that counts the AMOUNT of the load. It’s a 2 ohm load at what? There is not an unlimited demand, why are you acting like there is an unlimited SUPPLY. Your "cable run" numbers are WAY off.. Your limited by the wall current and 15 or 20 amp breaker.. It’s a supply and demand issue, why are you trying to meet a demand that CAN’T be there.. 100 amp breaker maybe.. LOL

What are you running for amps the old Lincoln torpedo arc welders... ????
