Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker

geek101 OP

BTW geek101 OP your Legacy Aeris I just noticed are 94db!! why do you need more than one AHB2, one is plenty and will do the 4ohm load on it’s ear, and not have any disadvantages of it bridged.

A bridged one beside all the cons I mentioned, will be looking at a 2ohm load and if that speaker has high -phase angles at 2ohm impedance dips, it could be even lower as seen by the amp.

@georgehifi Legacy Aeris is spec'd for 500w. I am just considering starting with a setup that does it all when dealer comes to calibrate. If I consider the cost of extra Benchmark it is 10% of my system and I can always sell it or re-purpose it.

The challenge is find 500w of cleanest power that does well in rest of the parameters (current, voltage and damping etc) and optimized for price. 

To my limited knowledge even after bridging Benchmark seems to out perform its peers. Correct me if I am wrong. I am happy to learn more.

@twoleftears Is that sarcasm or a fact. Sorry sometimes I don't get sarcasm.

Probably peak also.
Here’s your spl at 3mts in your room for a stereo AHB2 seeing a 4ohm load (210w) into your 94dB effcient speakers.

110dB spl! say good-by to your hearing.

And "if" they were 8ohm 94dB speakers and your amp would give then give 105w your still at an in room SPL of 107dB!! still ear shattering!

To my limited knowledge even after bridging Benchmark seems to out perform its peers.

If this were the case, and there are no downsides as I've explained, then why not just have bridged amps if they out perform in all areas.

The latter...
