This subwoofer normally goes for at least $499. I tried to get B&h to price match but they couldn't do it - they could only give a $25 discount off their $450+ price.

OK, I'll ask:

Given moderate listening levels for music and movies (not shake-the-house levels), generally speaking, would it be preferable to go with two of these or one bigger/more powerful sub?

This sub will be fine for music, but for Movies it will not play low enough. Search your subwoofers on avsforum.com to get a better idea of what you need. I would go no smaller than a 12" for movies so you can get the low frequencies. 2 subs is always much better because if you have one in the front corner (subwoofer placement is very important) then the corner of the room on the adjacent wall will probably be much louder than the opposite corner. Personally, I would get 2 of the Dayton 12" subs for the same price. Even go with the 15" subs from Dayton if you can stretch your budget. Take your time moving your subs to different locations because you can easily double the output by putting them in a good location.

The old advice of corner placement didn't do me any favors. I had mine there for years. Then I got measurement equipment. That spot (measured from my seat) was killing the bass below 25 hz! A spot along the wall about 1/4 width of my room was much better.
If your room is not a closed rectangle, you can basically throw out all the "advice" about where subwoofers might work best. You are going to have to either do the sub crawl or take audio measurements if you want the best out of your subwoofer.

The RSL Speedwoofer 10s is currently backordered (Covid effect). I would sign up for an in-stock notification and use that time to save up another $100 for a "better" subwoofer than this.

So you are pitting dual 120watt subs that only hit to 25hz against a single 300watt sub that hits to 18hz?

Some REALLY bad advice here.

Some people prefer smooth, even bass from two subs placed across the room from one another, versus deeper, but uneven bass from a single sub.

And to discount your previous advice about it all being about placement just to be a counterpoint is disingenuous.

Huh?
It's simple. Some people value the deepest bass response above all else (you, apparently). Others value a more even bass response across more areas in the room more than they value reproducing the deepest bass frequencies (put me in that camp).
It's impossible to get even bass in a room with one subwoofer....unless you sit in one seat and do a lot of bass equalization.
When I moved my single sub from a corner to about 1/4 width of my front wall, the bass response from my seat got way better. THEN, I added a second subwoofer and I got more even bass across more seats.

I read a review from someone who owned this sub and said that is rolls off around 36hz. They list it as being able to do 18hz, but they do not specify how many db it is down by the time it gets there. You will be hard pressed to find a 300w, 10" sub that does 18hz at -3db. I stand by my advice.

This is another typical def tech product with extremely overrated and exaggerated specs, no way this thing hits to 18hz with any kind of usable output. I have listened to and owned many def tech products over the years and the two things you can count on from def tech products are a high failure rate on their amplified products (i.e. - their subs), and that their frequency response ratings are ridiculously exaggerated. A decent sub here, but don't kid yourself, this doesn't hit lower than $1000 12-15" subs from rel, hsu, or svs for example.

Generally, you'd prefer having two subs over a single that's slightly better, as it will not only extend lower due to the increased amplitude due to addition (superposition), but it will also be more even.

But, for something like two of these versus something like a HSU or SVS, I'd choose the single sub, as those are vastly superior to these (not slightly, as in the above example).

I looked this over out of curiosity and I'll say this; somewhat in defense of this subwoofers claims. The reason a 12" or 15" subwoofer goes lower basically comes down to it moving more air per stroke. This, coupled with the capacity for a larger spider structure and magnet thus more greater power handling results in the larger amplifiers and performance improvements we see. This subwoofer attempts to compensate for the reduced surface area of a 10" driver using a high excursion design having a longer stroke thus moving more air than a typical 10" design would. This design requires a more substantial spider and magnet structure than is typical and also additional power, manifested here as 750 watts which is quite a bit for a 10" sub. I'd say all that gives them room to suggest this can compete with 12" subs. HOWEVER, I wouldn't think for a second this could compete with great or even probably good 12" subwoofers and definitely not SVS like numbers. So like most things it is probably priced where the market has put it. Competing reasonably well with most designs at this price point. If you really want or need a 10" for space, esthetics,(wives) or whatever and want to tell yourself you aren't missing out on anything you will probably be happy with this but I wouldn't think it's particularly a steal or superior to a well priced $300 12" sub.

I just got 2 of these and one died in an hour. They did sound great while both worked. I knew the reliability of these were not good as reviews of them keep mentioning that they broke quickly, but I took the chance because these do sound really good and were really cheap. If I were to do it again, I would not buy them even at this low price. The low price is what got me. I was thinking $600 dollars for 2 subs (so cheap!) I didn't think clearly as $600 dollars could have gotten me an SVS PB-1000 Pro, which is way more reliable and the sound is incredible!

I am not sure what I did wrong. I plugged an rca cable to lfe port and the other end to a Denon subwoofer port and didn't hear anything from the subwoofer. Help, please!
