**HELP** FOCAL ELECTRA 1028Be sound issue (muffled)

sensitivity 91db, they should sound good being driven at normal volumes by nearly any amp, and this review says

"A single set of high-quality five-way binding posts is located on the rear." so it isn't missing jumpers.

unless they altered the design

@adbacl  -  Probably not the case, but just gotta ask.... Have you checked the cable connections to make sure you don't have the '+' and '-' reversed on one of the speakers.  One speaker being out of phase would do it.

Out of phase is what I was thinking. 

@adbacl - Any follow up on this?

Update on the speaker sound not being acceptable.

After speaking with a dealer, he suggested reversing the speaker cables (red to black and vice versa). Then use the preamp and then the amp. Next, I measured everything and checked everything on my Sansui amplifier. All tested good. The next step was to try a different amplifier. This was a hit. I tested with the tube amp (McIntosh 240). Speakers woke up, and music was just flowing perfectly. Next, I had an opportunity to hook up a solid-state Luxman L590-AXII. This was even better. To conclude my findings, those speakers need a very sensitive amplifier. Many of you in this post suggested going this route and were right on the money. These speakers dip below 4 ohms. Not many vintage solid-state amps can handle it. After all, I feel I have great speakers (just a little too bright, but I knew this was a characteristic of those speakers). Luxman handles it perfectly. Thank you agin for all your feedback. It was a great experience. I actually ended up buying the Luxman. I couldn't resist such a great deal on this gorgeous machine. Sadly, Sansui is going to be sold...
