REVEL performa3 f208 or TEKTON Moab

All speaker manufacturers should publish truthful sensitivity measurements.
Per John Atkinson very few do.
Most upgrade just 2 or 3 dB.
Tekton goes for 5 to 8 dB
Bargepoles come to mind.  If they are dishonest about one thing, chances are they will be the same on others.

And if you do buy Tekton, don't forget to order the optional large size black plastic bin liners to hide their toytown ugliness.

My son has a complete Revel system, and I auditioned the Tektons. Different models though. He has the next class down F35 and F36's with the 110 V2 Subs. I sent my Double Impacts back as I didn't think much of them and I LOVE his Revels.

To the OP, I'm was reviewing the thread but don't see how you came to narrow it down to these two. How did you? If you were to open it up to, say, four choices, what would you add in?

If you think that "better engineered" means a better speaker you're wrong.  However, there's a very good chance the Revel is NOT better engineered.  Check out GR Acoustics youtube channel and you'll see how crappily some high-end speakers are engineered and cut corners.

If you think the Moab is only for partying or rock, you're smoking crack.  

I trust little of what self-described "audiophiles" say on here.  I just got a pair of Klipschorns that are absolutely 100% phenomenal and audiophiles turn their noses up to them.  But as PWK would say, BS. 

All that said, and having owned Tekton (sold them) I cannot wait to own another pair. Saving up for the Moabs since my Double Impacts were SO good.
