LG is targeting the global warming conference attendees :p - Rich

My first foray into the wide dispersion speakers was the JBL XPL 140 that had a titanium dome midrange. This was in the early 90s. A local dealer had these hooked to CD player directly driven by an amplifier in a large space. I really liked the way the speaker integrated the drivers and the...

@Sonnie, I don't think that there is anything wrong with your listening session or conclusions. The 328Bes are rear ported and passive and do not go particularly deep, presumably designed for efficiency and to paired with a subwoofer. A rear port can benefit by placement near walls, again not...

Thankfully, Atmos can be kool-aid free. - Rich

Hopefully, MQA will enter the dustbin soon. IMO, Atmos is the next big thing in streaming audio. - Rich

I liked the power cube and discussed it with Gene (Audioholics) and his only criticism was the lack of distortion measurements, which I think is fair. Here is an article from Audioholics on amplifier measurements: Audioholics Amplifier Measurement Standard | Audioholics - Rich

Here are resistors sent by Emotiva to Audioholics to review their XPR-1 kilowatt plus amp. Emotiva XPR-1 Mono Amplifier Power and Distortion Measurements | Audioholics - Rich

I have never seen anything like that. I think reactive load would be ground breaking. I am using this device. Unfortunately, it is intent on destroying the human race, so I can't let it out of the house. - Rich

Titanium. If paper, who knows, fire :explode: The electrostatic speakers look like radiators, so perhaps heat is not an issue. - Rich

15A recommended power: I am not sure if you can blow these speakers like you can a tweeter/midrange, but the Martin Logan recommendations indicate there is a limit. I cooked a Salon1 midrange, it can be done :p - Rich

These might have worked on the cheap :) P701 Hypex Ncore NC1200 Amplifier | March Audio | Australia - Rich

I would state it differently since speakers are driven by voltage. It is not that an amp is constant power but that it is load invariant, able to supply a lot of current to properly track the voltage amplification. When the power sags, the voltage cannot not be maintained either lowering the...

Are you able to reach > 110 dB using the 328Bes with the AHB2 bridged? - Rich

Using Sonnies measurements and using Ohms law to compute the voltage gain for each speaker and amp the volume dBV levels that, in theory, could be obtained: 15A - 2 Ohm Load Watts Max Voltage Max Gain dBV 2.83V db Est Max Vol AHB2 Bridged 450 26 19.3 91 110.3 Megtech 900 36 22.1 91 113.1...
