Default The Little Engine that couldn't

just finished or at least stopped with the 'break in ' of my CHp 70.2 drivers 120~ hours at lowish levels via radio.
Differences? None.. that I can discern.
Photo attached of these temporarily installed into Thrift store Sony boxes
Also of one the 40 year old, locally made non descript 8' full rangers that I've kept since new... simply because it/these worked a helluvalot better than a pair of Dynaco A25's I briefly :-) owned.

Had Kids over visiting so I arm twisted them into auditioning the MA's.
Two of these young men are musicians whose 'band' regularly appears on CBC radio and television. Likely familiar:-) I thought they could listen with some skill.
Resultant impressions ranged from: Ewww .. to: I hope you didn't pay much.
Pretty well echoing my observations, albeit far more bluntly though.
Tinny sounding and frequency constrained.. clearly outclassed by an 8" whizzer cone ..Geez.
Which also works a .whole world better than the wee MA gizmo in it's junkyard enclosure.
Hey! Not compared to Tannoys in GRF's enclosures ..this time.
This is a crabapples to apples comparison. Real world Fair IMO.
.
Maybe it's down to the crappy box. Not convinced on that one though
So what gives? Crap product? Spiked Kool Aid ? Or simply Emporer's new clothes?

I've seen a lot of Audio systems.. many clients request bespoke AV setups in their megabuck mansions.
Typically well north of $250K.
As result I've seen /heard /signed off on more Primo (claimed) Audio setups that most get to see let alone hear.
Have learned, through osmosis :-) what is good and what isn't.
Lots of the Mega $ stuff is Sketchy. (B&W Snails for sure :-)
However the truly good equipment is jaw dropping good.
I'm begining to suspect/realise that these miniature full ranger adventures are decidedly in the Shallow end of the Hi End pool, producing just enough hint of goodness to keep 'em trying.
Hell, even Lowthers have perennially proven iffy, far more often than not... not new ground.
An interesting distraction, for a while ..I think it's over now though.
Thanks for the help.

I'm guessing it's too small.

You do realize the CHP-70.2 was designed to have a rolled off treble, starting at 7kHz? This is the only MA driver that has this feature "built in" on purpose AFAK.

Just what did you expect? Common sense tells us a four inch driver won't accomplish much. There are legions of Full-Range fans listening right now, this very second as you read this......Of their 4" drivers marveling in the nuances of vocals & the violin.....alto sax, and many more. When these enthusiasts walk away from their systems to "I'm going to the store, be right back!".........In walks teenage son & sneaks his latest CD into Dads "Super fullrange" system & cranks the volume up.......the poor little Four inch driver starts hammering against the "stops"........Teenager gets look of horror......thinking he has broken dads primo set-up.
"What a piece of junk" son says to himself

It does need a fair shake in a box actually designed for it. Might still not be your cup of tea, the FR thing so far hasn't proven to be mine...

I would understand if that was a sealed enclosure to test the driver but it's a reflex. The alignment could be way off.
Try and model the driver and see if you can mess with the port length and report back. Also if it sounds extremely tinny, maybe they are wired out of phase?

Same here, I've played around with a FR125 recently, and though it sounds pleasant enough, it just doesn't do scale, dynamics and imaging like a good three way.

I can't remember exactly but I think it was something like treols graven web site but anyway, I read with some drivers, if you don't get the cabinet right, they could sound totally "off".

I like my Creative T12 speakers which have tiny full range drivers. I know people who prefer to listen with subwoofers would freak if they heard my speakers. I'm still amazed by the voice quality.

That being said, I sometimes crave more bass. So, my research is leaning lately more towards woofer/tweeter combinations. (I'm somewhat hesitant with 3-way and woofer/full range combinations.)
