Monoprice open box and B stock audio gear is drawing attention for steep discounts on subwoofers, speakers, and home theater amps, with the MM 5R, M 12, and M 10 deals standing out. The value looks especially strong when shipping stays reasonable, and the standard five year replacement warranty is still attached to open box items. The main drawbacks are shipping damage and heavy, awkward subwoofer deliveries, with some units arriving reboxed or with broken grills. A few amps and subs also raise reliability questions, so the appeal is strongest when the discount offsets the risk.
Home theater buyers wanting a powerful subwoofer for the money, because the M-12 can deliver comparable performance at a lower price with the same five-year warranty as new.
Speaker hobbyists comparing dome and ribbon tweeters, because the MM-5R open-box price is unusually low and the MM-5 has been a daily driver for years.
People who need a subwoofer that is ready to use out of the box, because a unit can arrive with a broken grill and enter protection mode after a few minutes.
Buyers depending on long-term support for discontinued amplifiers, because the product has not been made in almost two years and amp failures may be hard to resolve.
They can arrive in good working condition, but shipping damage is a real risk on these heavy subs. One Mono 10 arrived reboxed and worked fine, while another M-10 v2 arrived with torn packaging, a broken grill, and a repeatable protection-mode issue.
Yes. The open-box items are stated in the product Q&A and included paperwork to carry the standard 5-year replacement warranty, the same coverage as new.
The M-12 at about $600 after shipping is described as still reasonable, and the Move50 code can put a unit around $500 plus shipping, below the prior $600 price. The value case is strongest if you want the performance and warranty, but shipping can erase some of the savings.
The MM-5R open-box price is described as the lowest seen, and the set was bought for $50 off. The MM-5 silk dome speakers are also described as long-term daily drivers, with the Ribbon 5R being the comparison target.
Yes. One buyer notes Monoprice has labeled older merchandise as open-box to clear inventory, and a Mono 12 open-box purchase from that period still worked well years later.
Thanks - got the MM-5R's open-box for the lowest I've ever seen them. I have the silk dome MM-5's and want to hear the Ribbon 5R's in comparison. Highly recommend, they've been my daily drivers for years.
Details should mention only on very select items. If it works for you should be good deal, but everything I am interested in of course it does not work.
$500 plus shipping with the Move50 code is still below $600
You wont find anything with that same level of performance for that price
same warranty as new...5 years
The other part is
I have seen manufacturers label things as open box to move older merchandise and not have to price adjust
I have bought Mono 12 open box before...the V1 variety( for $407 free shipping), right after they released the V2
When I got it I certainly didnt think it was really an open box
2.5 years later it still works great

Open-box purchases can still include the standard five-year replacement warranty for Monolith subwoofers.
Move50 pricing can land below prior full pricing while keeping the same warranty as new.
Some Monolith subwoofer deliveries arrive reboxed but with all contents intact and the sub appears to work fine.
Monolith M10 V1 owners report long-term operation in a 5.1 setup without issues.
Shipping can be problematic for open-box subwoofers and may lead to transit damage.
Some open-box or refurb listings may not reflect truly open-box inventory, which can affect expectations.
An M-10 v2 can arrive with severe box damage, a broken unusable grill, and a repeatable red/green LED protection mode.
Monolith home theater amplifier pricing may exclude many units, making the advertised starting price hard to find.
