Rated 5 out of 5 by from Amazing sub for the priceI ordered this to go along with my first 2.1 set up. I ordered an SMSL-SA50 T-Amp and the Micca MB42X (Which both of those work great as well! I highly recommend them to go along with this sub if you're on a tight budget.) I'm extremely happy with the sub in this set up.I'm using this 2.1 set up in a somewhat small square room and it works out great for me. The sub is fairly big so if you have a small space make sure to measure before buying.Depending on the genre I'm listening to I'll lower or raise the gain and crossover to what I prefer personally. I generally listen to heavier music like metal and the several sub-genres it has. I also absolutely love having bass, it creates a nice warm feeling for me. These subs don't give a very overwhelming feeling (Punchy feeling I guess?) but they create a great warm feeling environment for the music I listen to. The sub makes all the difference to my set up, without the sub it's somewhat dull with just the speakers. - One last thing I almost forgot to put in here and I don't know how to fit it in, when I turn up my amp and sound fairly high the bass is very powerful. I can hear throughout my entire house and it rattles everything.I guess I'll just stop there. It's a great product that I definitely would recommend to anyone especially for the price. Highly recommended.

Rated 5 out of 5 by from Lots of boom for the buck.I have a pair of F15's in my entertainment center, but needed something for a secondary system. I was thinking of DIY, until I read several good reviews on a forum, touting this sub. I was hesitant at first, but at this price figured that I could always use it as a gift, if I hated it. Well, I was surprised and pleased. Not in the same league as the Rythmiks, but surpassed my expectations and can't beat he price. Its not a one-note, boomy sub. So,I think I'll keep this one.

Rated 4 out of 5 by from dayton 1200 subI recently got the upgrade bug and upgraded my ht music system, Yamaha top of the line aventage receiver ,salk songtowers,samsung tv,it left me little to spend on a sub,I researched a while and bought a Dayton 1200 and I am really glad I did ,it blends beautifully with the rest of my system,and what a bargain! I may have to buy another one and run dualies!

Rated 5 out of 5 by from Fantastic for the price!Coming from an 8" Sony powered sub from an HTIB kit, I have this sub paired with the Pioneer BS41, C21, BS21. All I can say is wow! I'm sure there are much better subs out there...the problem is they aren't priced anywhere near $100. I now have the ability to make my basement rumble when I want (not often with a toddler running around).

Rated 5 out of 5 by from Awesome for the priceNot as powerful as I was expecting, but a great unit. Clean sound, lots of options, and easy to hook up. For this price, you cannot go wrong.

Rated 5 out of 5 by from Great Sub for the priceThis is a very musical sub. Unlike others in this price range is actually plays down to 30or 40hz and below. It will rock your surround system and is good for music. I have too small front speakers and I bought 2 of these. One I run around 30-40hz and the other around 120 and below and I am careful to use the phase switch to make sure they don's cancel each other out. This rocks are large living room. My last sub was a 3000 watt Sunfire at 10 times the price and honestly I don't hear a big difference.

How does this sound with music?

I was trying to decide whether to buy an 8" or the 12" dayton.I know the 8" will sound better with music but I want as much bass as the 12" produces.
Asked by: GrantD
You're referring to the quicker response of an 8" vs. 12" in general application. Yes, generally speaking, an 8" will respond ("attack") faster than a 12" for obvious reasons (size and wattage requirements). BUT, in my experiences, your foremost concern (quality being constant) should be with matching the sub size and wattage to the woofer size of your main/rear/center speakers. How much of your listening spectrum is the sub responsible for? For example, if you have 10" woofers, generally speaking you'll want a 12" or 15" sub to cover the really low end. If you have 6" or 8" woofers, try an 8" or 10" sub to help cover the higher low end. It's all about "gaps" in listening. Don't create them, conceal them.A lot of what your hear and what is "great sounding" to you is subjective. Some people want a "boomy" sound and dominating sub. They'd rather feel the explosion than hear the words. Some people want a blending and more harmonious and naturally sounding system where the speakers almost disappear as the sound they produce take center stage. For example, I would not buy a 15" sub for 6" woofers. You would be leaving a large midbass gap that would give your system that "boomy" feel.Yes, a 15" sub will produce much better bass than an 8" sub. It's simple audio science, you need to move air to create bass. The more air you move, the larger/better the sound. BUT, bigger isn't always better.With 6" woofers, an 8" or 10" sub will sound more natural to your overall system. Even though a 15" sub will shake your house.With 10" woofers, a 12" or 15" sub would be perfectly matched. While a 8" or 10" sub would almost seem to be unable to overcome the presence of the 10" woofers. Your sub generally needs to displace more air than your woofers to get the natural blend you expect. This isn't science... this is 30 years of listening experience.I would recommend the next 1 or 2 sizes "up" in sub diameter compared to your woofers. Typically, if you're adding a sub then you've already achieved satisfaction with your other speakers and you just want to "add" what you're missing. So, you don't want your new sub to suddenly shift your focus to it when you're listening. You want your focus to remain where it has been.... up front.Try for yourself, and let your ears decide. Remember, if it sounds good to you.. that's all that matters.

dayton sub 1200 + dayton b652 + lepai amp

From the video i learned that i can connect my b652 to the sub and back out to a receiver. the problem is that i want to power all 3 from my laptop.would i able to connect my b652 to the sub and wired back out to the lepai amp. so that i can control the b652s from my lepai amp and not the sub. i dont want the gain from the subs to power my b652 i want to power both sepertaly but connect them all to my laptop. would it better if i just got an auxillary splitter and have one aux cable to the lepai and the other to the sub? (connect to an rca adapter of course)
Asked by: dredey
Yes this will work with a Lepai amplifier. You will have to plug the Lepai into the output of the laptop, run the speaker wires into the speaker level inputs of the subwoofer and the outputs back out to the B652's. The gain on the subwoofer will still be independent from the Lepai, but the Lepai will control the overall volume.

RCA signal

I'm confused about the low-level inputs. I have a Dayton APA-150 amplifying stereo output from a TV and connected to floor standing speakers.Would I split the RCA signal coming from the TV and send it simultaneously to the APA-150 and the subwoofer?Or, must the RCA inputs be pre-filtered, and therefore, I need to use the high-level input option?Thanks....
Asked by: Signal Distortion
You can use unfilters inputs for the RCA's, the only problem with this is that there is no way to control the volume of the subwoofer without manually turning the gain knob on the back. I would recommend using the speaker level ins and outs for convenience if nothing else, this will allow the volume on the APA-150 to control both.

Is there a high-pass filter for the speaker output, and if so what frequency is it set at?

Asked by: wbogot
If you use the low-level inputs, there will be no signal present on the high-level outputs. If the high-level inputs are used, the high-level outputs will be full range, there is no high pass filter involved.

what is the diameter of the actual driver in this sub?

Is this a dual voice coil speaker? And what is the nominal Z of each coil?

Asked by: Pgoodwin1
No it isn't. Dual voice coil subwoofers are common in passive subs. Since this is a powered sub summing of right and left signals occurs in the built in amplifier.
