Background- I owned a stereo store for over 25 years back in the day, so I have a pretty extensive background in audio technology. I would rate the sound quality of these good, but not great. And they do have a lot of features for the $$: wood cabinets, remote, two analog inputs plus bluetooth. If you intend to just use them by themselves, they seem like a very decent value.
My issue with them is a feature that appears on the back panel but is not in their specs or description: a subwoofer output jack presumably for connection to a powered sub, and that's why I purchased them, to use with a Mirage sub I have. In order for the sub to work properly with powered speakers, the level of the sub out jack on the Insignia's should track the level of its speaker volume control, and I assumed it would, just like 100’s of other products that feature a mono sub out rca jack. But this product doesn't- the sub out is at max volume all the time. I assumed I got a defective pair, in part because when I got them home the bags the speakers were packed in were ripped and had obviously been opened by someone and returned. Not sure why BB thought it was OK to resell them as new, not Open Box, but that's another issue. I ordered a second pair from the website to try to assure I got a new pair from a different production run than the ones in the store. Looked brand new, but the second set had the same problem. I still hoped it might be a production defect, as opposed to a design defect, and might not be present on all examples so I exchanged the second set with a third one. Unfortunately, it had the exact same issue (and btw, it also had been previously opened- what’s up with that?). I looked for any other information on the Insignia website, and found a full instruction manual there (one had not been included with the speakers- just a quick start guide). It did not show anything hooked to the Sub Out jack in any of the configurations they illustrated, or mention the jack anywhere, leading me to believe that they realize that it was not designed correctly, and they are just pretending it isn’t there.
The fixed output makes using them with a sub impractical -you have to adjust the sub level separately every time you adjust the speaker level via the remote. Again: if you don't plan to use a sub (or will control the sound level exclusively from your source and not use the Insignia’s own volume control) then these are a decent choice given the feature set, especially when on sale for under $150. In the end, I decided to keep them- I will use the left channel speaker output to feed a speaker level input on my Mirage. I'll only be getting one channel, but most bass in recordings is mixed to both channels to get the maximum lows a given pair of speakers can produce, so it will work, if not ideally.
One other thing- my experience with both Geek Squad and Insignia in trying to get answers to this issue was uniformly poor. Three GS agents I spoke to on the phone had no knowledge about the product category, much less this specific item, and the Home Theater department manager I spoke with briefly claimed that all subwoofer outputs on home electronics are fixed level. I was surprised at this basic lack of knowledge, so I asked him if it made sense that every time I change the volume on a sub/sat system I have to walk over to the subwoofer and adjust it separately? He still didn’t back down- all subwoofer outs are fixed according to him. So apparently he intends to keep disseminating his incorrect assertion to other BB customers. Not a good sign for the training level at BB.
FWIW, the Insignia 800 number (Insignia is a BB private label) hung up on me twice as soon as I identified the product and problem, again making me wonder if this is a known defect in a feature they are now trying to pretend doesn’t exist on this product, despite the presence of the labeled sub out jack. At least BB could Photoshop the product picture of the jack panel so the Sub Out jack isn’t there. That might cut down on the number of returns due to this issue. Which apparently are quite a few, given that two of the three pairs I received had been returned previously.
