Please report back, would love to hear how it goes. Their prices are great for larger panels (which ML charges a lot for), not so great for smaller panels since I assume their cost is mostly labor which isn't all that different for different panel sizes. The price they quoted me for the Aeon i...
This is exactly what worn out panels sound like. Washing isn't going to help although you can give it a try. They need to be replaced.
Since you are in Germany you try contacting https://www.hifi-zenit.de/ who rebuilds the panels for less than new ones cost from MartinLogan. If you do please...
You will very likely end up with comb filtering where the waves from the two speakers interfere with each other and you have dead spots and loud spots as you move along the axis.
We use an air purifier for health reasons. And dehumidifier because at one point we had a mold issue due to the humidity (not uncommon for Singapore). Having both of these make the environment more pleasant, the fact it helps my panels is a bonus :)
Maybe Robert D was referring to me? I live in Singapore and we've communicated over many threads. I live in Singapore and have pairs of Prodigy, Summit and Aeon i. I think my climate is very similar to Philippines (hot and humid). I do have a dehumidifier and air purifier in my living room where...
Above about 600Hz your SPL is about 10dB down (65dB vs 75dB) so the panels are likely degraded. Room correction can fix it by boosting the level by 10dB then reducing frequencies below around 500Hz. It will be a lot more demanding on your amp.
I have a Stage X and the panel volume is low. With Audyssey room correction on my receiver I can still get a relatively flat response out of it. It also helps that the Theater and Stage have tweeters so the panels only cover the frequency range around 300-3000Hz.
I had Russ repair my Aeon i and...
The time duration varies greatly. It can be 6-20 years. But it should be very clear - when your speaker starts to sound muffled and missing treble, that's when you need to replace the panels or consider washing them.
