Idk how it's poor. Anyone I've read needing a replacement has gotten one. It's a 5 year warranty. Both of my 15"s are perfect.
Edit: what could the Monolith elves be making!? https://mobile.twitter.com/monopr...4509663232

These perform well by every metric, much better than SVS (overpriced for what you get). However, if you read the forums you'll see there's issues with the plate amp failing, requiring shipping the entire sub back rather than Monoprice shipping a new plate amp. Also, customer service is poor overall.

I'd still stick to PSA, HSU or Rythmik.
I have read the forums for months and simply dont see the plate failure...at any concerning higher rate...that you mention

On another note..I think HSU requires you ship the sub back as well for warranty work

Because this is thru Target would a return (first 30 days) be to their store or would need to ship it? In case not happy with it I mean.

In for two 15". I just moved in to a new place with a much larger living room and my old sub just isn't keeping up. Was debating between the monoprice and SVS subs and basically decided whichever one came with a good deal first I would jump on it. Well Monoprice won the race so here we go. Cannot wait to try these babies out.

EDIT: I am also about 70 minutes from monoprice headquarters if I ever need to take it in for warranty repair for some reason, so that helps the decision.

I'd get dual 12's in a heart beat vs. one 15. unless you're planning to get one 15 now and another
later.

Does anyone know if this will work with KEF LS50 wireless? I'm not an expert on this. Would appreciate some insight. Ready to pull trigger if so

I would disagree, it comes down to your preference/expectations.

I've personally compared many of these subs including monolith vs SVS.

IMO in layman's terms, if your main concern is shear excursion Monolith has the edge.
If your main concern is articulation and detail SVS has the edge.

SVS hands down has the "better" CS which you eluded to.

In the end either is a good sub.

I agree with everything you said accept HSU. In my research their QOA isn't that great and the 1 person they have answering the phones is not the best either. They don't stand behind their products failing. I researched the crap out of subwoofers for home theater for a year before I pulled the trigger. In the end i narrowed it down to monoprice or rythmik. But decided to do Diy cuz I'm cheap. Diy is best bang for you $ if you haveva little know how
I have a full HSU setup and it is 👌 Both the 15" Sub and bookshelf speakers which punch above their weight. No regrets in going with them.

How big of a room do you realistically need to use a sub like this? I have a 500W 10" REL subwoofer already, but it doesn't give me the chest thump I want unless it's really really loud.

Take a look at how it does with the CEA-2010-A test. It's not terrible, but It doesn't keep up with either of these monolith subs.

Same. I haven't had an issue with my plate amp on my 15 and I've put mine through some abuse. Just got my second one a few weeks ago. Still need to plug it in. Hopefully I'm not jinxing myself hah. Sub is incredible with both movies and music. I was worried my 30 ft ceilings and mostly glass corner loft would be too much volume for two of these but the one has way exceeded my expectations.

I have a 10 too and love it but I feel it lacks low end punch. Do you feel the same? Thinking of going with 15.
I have a 10 inch and it has great low end even below 20hz. Have you done measurements with software like Room EQ Wizard? Maybe your seating position is in a null where bass doesn't sound it's best.
