Nice arrangement and I definitely like your built-in wall elements.

System #500 (Monolith-III, Monolith-III, Monolith-III, Theater-I, Dynamo 1. Name: Chris 2. Location: Palm Beach, Florida - USA 3. ML Model(s): Monolith-III with Active Crossover Front Main L/R Monolith-III with Active Crossover Surround Side L/R Monolith-III with Active Crossover Surround...

You should abandon those passive crossover boxes and use an active crossover as JonFo recommended before making any other alterations because it will be a tremendous improvement. I would have both woofers reconditioned as the specification are hard to equal. Here are the parameters for the...

I just regurgitated some apple chunks listening to that gospel. Those lights on the Apogee speakers are interesting and was considered doing something similar with some 5050-LED RGB light strips behind the panels on a music controller. https://youtu.be/MR9ehP80E2E

The companies listed below are also well known for carrying a wide range of loudspeaker replacement parts as well as reconditioning services and may be able to assist with your service needs: Advance Sound 1201 Hilton Rd. Knoxville, TN 37921 865-558-5770 www.advancedsound.com Audio Lab of...

The missing resistor is not the problem. If the red led on the power board is illuminating faintly only when the micro switch is pressed, your music sensor circuit is not activated, assuming you have the speaker wires connected to the music sensor terminal block connector with music playing? I...

It appears as if all three resistor locations are wired in parallel to the LED terminal block from the NPN bipolar junction transistor Q2. Your power board has a 2K-ohm resistor in R1 position and a 6.2K-ohm resistor in position R3 while the other European power board has an extra 2K-ohm...

Can you post a good picture from the rear of your power board to figure out the schematic lines at the R47 missing resistor location.

I would check the light switch SX2 in the schematic below and the ten screw terminal connections from the red & black zip cord wires coming out of the bias board to the blue LED. You may have already shorted out the transformer or damaged the triggering circuit on your bias boards by using a...

That's just a quad operational amplifier for the music sensor trigger circuit and the numbers often change due to different production runs. You can probably type in that number on the web and find five or more different substitute numbers that will still function in the same way. If you have...

The transformers have two primary windings and it's connected in parallel for 110V 60Hz US and in series for 220-230V 50Hz UK Europe. http://www.martinloganowners.com/forum/showthread.php?15057-Martin-Logan-Aerius-i-New-HT-Board-Repair-HELP-!! I would remove the two jumpers in the A-position...

I'm 100% sure your bias boards can be converted to the 220 voltage standard if they appear like this one in the picture below. There's a jumper pin or two that looks like a 1/4-watt tan resistor with a single black band that needs to be relocated. If you can post a close up picture of your high...

I would not attempt to transform your speakers voltage input by external means because they were designed to operate on the two different voltages with some simple internal modifications. You will need to change your 110V power cables to the 220V power cables with the appropriate wall plug and...

I believe you would be better off using the acoustic pyramid foam or convoluted egg crate foam to line the walls of your woofer cabinet. http://www.foamforyou.com/Eggcrate_Convoluted_charcoal_foam.htm http://www.foamforyou.com/pyramid_foam_tiles___sheets.htm#4

The Monolith-III bias voltage is around 3,200VDC with four 15M-ohm resistors in series at the end of the circuit. Be sure to include these resistors at the end of the output of the supply because it insures that you can't get enough current out of the power supply to hurt you. Second, it helps...
