I see that you took pictures of the internals of the Sub 1200. I am curious as to what that woofer might weigh. I tried Parts Express's product support person and he was unable to tell me anything about the woofer's magnet weight or voice coil size. It apparently isn't a woofer that Parts Express sells separately. I am in Canada, where electronics are considerably more expensive than in the States, but I have owned subs costing five or six times as much as the Dayton Sub 1200 that did not outperform it and suffered from deal breakers like amplifier hum or one note bass. Loving my Sub 1200.
I'm glad my review was beneficial, and that the SUB-1200 has worked so well for you. It's always nice to hear that someone has found value in one of my evaluations.

Historically, the only time I've weighed a driver is when it seemed to be abnormally heavy. That was not the case with the Dayton sub, so unfortunately I don't have an exact weight. The enclosure materials didn't strike me as overdone though, so my guess would be the driver was close to 50% of the total weight. If that proves true, figure 15 pounds or so.

Just curious, but is there a specific reason for wanting to know the driver weight? Several factors come into play when determining the capability of a subwoofer, none of which should be considered in isolation.

Thanks for your reply. I guess I equate woofer heft with quality, kind of like a beefy power supply in a power amp. But I admit that I know nothing about whether a woofer with a 16 ounce magnet versus one with a 16 pound one equates to anything relating to its performance capabilities. It's just that I have had some unde-rperforming speakers in the past and some of them had weeny magnets.

I conveniently have the speakers out of the cabinet. They weigh 6 3/4 lbs. total each.

Interestingly enough I checked the weight (for example) on the Dayton 12" HF driver and it has a magnet weight of 150 oz with a total weight of 25 lbs.

Hi Jim,

While still happy with my Sub 1200, I have read reviews that it is under powered. I spotted a used BIC F12 locally for a great price. Would it be an upgrade? If not, how about an Energy S10.3?

It's not really underpowered for what it is, a very inexpensive subwoofer. Given the cost of the parts PE can use it's actually pretty well balanced. Whether it's an upgrade depends upon what you're looking to achieve though.

The F12 is likely to have a bit more total output, and the Energy perhaps a touch more articulation, but either would be more evolution than revolutionary. You may be able to integrate either with the SUB-1200, but it would probably take a little bit of time and effort. That might be something to consider.

I still have the sub 1200 ( I have 2 of them)and find that it has more than enough power in my small 15' x 15' room.

So it depends on what size room and what level you listen. A big room requires more power.

My understanding is that watts are watts. If your bass demand requires no more than say total of 100 watts of power then having an amp that can supply 300 or 500 watts is not any better than an amp that has 125 watts. I can play incredibly loud from the 1200's 125 watts of power amp. (I worry about my neighbors complaining from the house next door.) The gain knob is set around 11:00.

The cabinet the 1200 is just fine also. The weak link imho is the driver. The only change I made was replacing the stock drivers with 12" NHT 4 ohm speakers. This change made a sizable improvement in quality of the bass. I stuffed the cabinets and sealed them.

A great replacement driver is the Dayton Audio RSS315HF-4 12" Reference HF Subwoofer 4 Ohm. The 1200 amp will drive it just fine. This is a pretty easy to drive speaker 90.3 db 2.83volts/ 1 meter.

This driver should drop right in and can be used either ported or sealed and is a far better driver than the one you're using. BTW... there is a re-stock available for $81 right now.

The room is pretty large (14 by 23 feet) and opens up into the kitchen, dining room, living room and entrance hall. I also have a Tannoy TS2.10 powered sub complementing the Dayton. I am not listening at loud levels and to be honest I have never felt the urge for a more powerful sub. But I just wondered if something like the Energy would be a substantial step up. However, I also have to think of my poor wife, who sometimes tells me to turn the sub level down because the bass hurts her ears. I don't think she would be too enthusiastic about having a monster sub in the room. Thanks for your replies!
