The Real Deal
on December 4, 2012
But there are a couple of myths, being two pieces of (...dare I say it?) outright misinformation that have become attached to this compact masterpiece, ...even though I'm sure both of them were offered with the best of intentions.
As for me, I thought I'd wait until I'd driven it hard and bounced it around the Aussie Outback for a couple of months before any attempt at reviewing it.
A little background: I'm an Audio Director/Sound Supervisor in my fifth decade of ongoing work in this field, most of it live (or "as live") and on location.
My Boss Audio R1100M is used to drive either full-spectrum sub plus line array or horn plus ported-woofer long range speakers (a choice dependent on the vagaries of weather and/or crowd numbers) at impedances from four to sixteen ohms, ...the only constant factor being the need to rely exclusively on DC vehicle power.
The verdict: ...five stars. No doubt whatsoever.
The Boss Audio R1100M delivers far more than something that's roughly the price of a case of beer should ever be able to do.
(What a crying shame that its excellent internal fan-cooling arrangements don't actually extend to chilling beer. Now that WOULD be a world-beater...)
To those well-intentioned myths:
First, "The Remote Subwoofer Level Control doesn't work."
Not when the amp's switched to "Full Range" it doesn't.
When it's in "Full Range", it isn't expecting to be driving just a subwoofer, is it? Switched to "Low Pass" (i.e. subwoofer) mode, the remote control works a treat.
Second, "It's under-powered."
Hang on a cotton-picking second, did you honestly expect to have mountain-moving power for the price of a case of cold ones?
Now look at it's main fuse. It's 30 amps. That's your lot, any more and it all goes dark and quiet until you replace the fuse.
Time for some basic arithmetic, 12 x 30 = 360. That's 360 watts of total power going in.
Wait a second, my alternator kicks out a gargantuan 14.4 volts! Whoopee! Hurrah! Huzzah! Hallelujah! I've now got an earth-shattering 432 watts at my command!
...Uuh, ...um, ...well, ...er, ...I WOULD have if everything inside the immaculately designed Boss-Box yielded 100% efficiency.
Sadly, 100% efficiency from ANY power system is the stuff of Nobel Prizes and/or science fiction.
(Trust me when I say that you won't ever again need to consult anyone's review of anything after YOU'VE developed a power system that's 100% efficient.)
Meanwhile, back in the "Real World", guess what?
With power being wasted to generate heat, run cooling fans and the losses inherent in each and every electronic step taken, the BEST amplifiers are around 25% efficient.
25% of 432 watts?
That would be 108, just a tad LESS than I (and others) have observed to be the continuous power actually (and reliably) delivered from this tiny Boss-Box into 4 ohms.
The controls all do exactly what they're meant to do. The sound is clean, gutsy and free of artefacts, so, by way of a conclusion, here's the outcome of some OTHER basic arithmetic I did prior to buying it...
I can't buy an aluminium housing of comparable ruggedness for the price of this entire amplifier.
