Anyone have issues with Revel Performa speakers


I recently purchased Revel PERFORMA F206 towers using an Anthem receiver and Rotel 1582 200wpc amp and after 2 weeks tweeter blew while1 not playing very loud. I went from Paradigm Monitor 11s and played them way louder without any issues. Going to a Mark Levinson 532h amp and hopefully can play loud without any clipping and the Revels hold up. Is this a known issue with Revels not taking playing loudly or possibly Rotel clipped and caused this ?? Or perhaps just a bad tweeter driver from the start ?

I looked at measurenents for Paradigm 95F Prestige

I could not not find anything for the 85F but the design is similar.

Tweeter is crossed over at 2KHz - so this little 1 inch dome is working very hard indeed. However the most concerning thing is the breakup of the mid range woofer at just below 2KHz.

Just look at how the linearity changes as you increase SPL - the mid range actually increases in output as the cone breaks up or resonates.

This is quite simply a poor design for playing loud as the design falls apart but as I mentioned this is not actually uncommon and I bet it sounds totally sublime at ordinary levels.

I am not sure where you are but try to audition ATC, PMC, Quested or any of the more traditional pro three way designs with a 3" or 4" mid range and a 15" woofer. Alternatively try a horn loaded type design like a Tannoy concentric (again with 15" woofer.)

If you like to play loud then nothing beats a tradional design (like JBL 4425 or large Westlake) with high bass output and reflex port designed for efficiency rather then bass extension (bass extension from reflex porting sounds resonant and can easily get out of hand at elevated levels).
The woofer and tweeter show driver compression at modest volumes 90dB SPL which is unfortunately not uncommon in many designs see link

The tweeter works a little harder in this design (a possible risk) than others as it is crossed over at 2200 Hz but this low crossover probably contributes to the great even sound dispersion and driver integration.

Note Soundstage normally include linearity measurements at 95 dB SPL - the fact they have not provided them suggests the speaker starts to stress severely at these still modest loud levels.

Looking at this design versus the Monitor 11 - these designs are both very similar - both have crossover around 2200 Hz.

If they played well for two weeks and the speakers are new it does suggest you pushed them more than the modest levels they can handle. If you like dynamics and loud clean sound then buying bigger amplifiers is not the solution - a more heavy duty speaker with pro type drivers (rather than consumer grade) might be the best direction to go.

The F206 is an excellent speaker but you may be pushing them harder than they are designed for.
