Has anyone had to return or exchange a
Monolith? If so, what was your experience?
Hello Avs Forum! I'm new here!
After all those raving reviews, and my personal research, I decided to purchase Monolith 15 directly from Monoprice.
It was on sale for $1199.99
Such a great deal, right?
So I received my very first Monolith 15.
I calibrated few times both THX and Extended mode using my Pioneer Elite VSX-LX303.
Aftet I checked my calibration data, I noticed something little strange🤔
My AVR gain is set to +6!
That's too much avr gain IMO.
I have my current subwoofer Polk PSW505 which is only 400 watt & 12 inch subwoofer.
It's supposed to be far less powerful than the Monolith.
But my calibration, PSW505 sets the receiver gain around -12db
How come my Monolith 15 calibration sets the avr gain way higher than my PSW505.
Also the sound coming out of the Monolith was tiny compared to PSW505.
Then I noticed back of my Monolith has flashing lights of green and red.
I was like WTH?
After couple hours of the light flashing, it was making weird noise like wind blowing or swimming inside of water.
Then I realized, I got a bad defective product.
I contacted Monoprice thru their chat, and i got their response right away.
They told me it's a defective product and will issue a RMA right away.
Yup, I received 2 emails including 2 PDF to send it back and get a replacement.
About 2 weeks later of my returning Monolith free with FedEx, I finally got my replacement.
So I hooked it up and did my calculations as usual.
This time my avr gain was set to +0.5db.
I guess it's better but still too much avr gain IMO.
Again, I compared it with my Polk PSW505.
My small Polk sub is still way louder, rich, powerful with clean bass coming out.
So I turned up back of Monolith sub gain to almost max, then I can finally hear a ok bass.
What I notice is that, my Monolith did produce loud right in front of it.
But when I step away just a couple feet, the sound is tiny again.
My calibration is correct with all the distances and stuff. I even added a few feet to the distance to get better response suggested by a YouTuber Subwoofer 101.
Still didn't get the sound pressure and volume i expected.
My small Polk PSW505 was roughly 4 to 5 times louder than supposedly a monster Monolith 15.
It shouldn't be like this!
I've really had it!
I decided to get a refund instead of getting another replacement😥
So I contacted Monoprice via email yesterday (6/24/20)and i got their response right away.
They said it seems to be another defective product, and they are issuing RMA to return the product.
I'll be sadly returning it later this week.
Such a bad luck i have...😭
To make my situation worse, this Monolith was for my birthday present. I just turned 43 couple weeks ago.
I'm highly disappointed😥
