I'd like to build a subwoofer that will be hidden inside an Ikea Besta cabinet. After deducting amp, driver and bracing, it looks like the largest box size would be 1.258 cu/ft. (The interior of the cabinet is 14.75" X 12.75" X 22")

Is 1.28 cu/ft enough volume for a 12" Dayton RS HF? I was told by PE tech support that 1.5 cu/ft is ideal for this driver.

Would I be better off going with a 10" Dayton RS HF and reducing the box size somewhat?

Thanks for the help.

It's a little undersized but it'll still work. You can practically get identical performance with a JBL GT512 for 1/3 the price

And the Infinity 1260W would work perfectly in that box

http://www.amazon.com/Infinity-Reference-1260w-1200-watt-High-Performance/dp/B0028AVGEO/ref=sr_1_1?ie=UTF8&qid=1357104051&sr=8-1&keywords=1260w

Use this Yung 300 watt amp with 30hz boost, and you will have pretty good extension down to just below 30hz from your tiny sub

Hi Jay,

Thanks for your reply.

If it makes any difference in my driver selection, I'm looking to build two of these. They'll be on the front wall and crossing over fairly high--120hz, or 100hz--to smaller speakers. The system will be in a NYC apartment so I'm not concerned about reference level SPL's or extremely deep bass.

Do you think the JBL and the Infinity are both equal in SQ to the Dayton RS--either the 12" or 10"-- subwoofer?
(I'll be building these to disguise them as part of the AV credenza, so I just want to do it right the first time. As a result, the box size cannot be any larger.)

If they're as good, do you prefer the JBL or Infinity?

Also, it sounds like you're recommending an amp with bass boost. I was looking at the Dayton 250 but if the Yung is more appropriate, I'll consider that.

Thanks,
Dan

The RS sub will definitely perform better at 120hz then the cheaper woofers, not sure if it's worth 3 times as much for that. I would probably take a look at this DCS305, which has a very clean top end, and works well in the small box.

http://www.parts-express.com/pe/showdetl.cfm?partnumber=295-204

As far as an amp with boost or not, it really depends on what you want. That DCS305 will have an anechoic F3 of 40hz in a 1.2 ft3 box, if you put 30hz boost on it, that will drop to 29hz. Considering you're in a NY apartment, I would probably just get an amp like this to power the pair of subs.

You would be able to get 105 db from each sub with 75 watts.

Not sure if you have started this but. I would not buy that Dayton classic dcs305 for $85. I have it in my a2300 and it sucks. I can't push it without it bottoming ands sounding like it is going to explode. For hwe money you can get better like the infinit and jbl. Just thought I would lt you know. I even plugged my port and it still sucked.

Did you model that woofer in your specific enclosure volume/tuning point/power level/ amp filter before using it? rolleyes.gif

nope it is what came in it from elemental designs. It does ok but complains a lot if you try to get a respectable amount of sound our of it. When I get my 1260w I will pop it in the same box and let you know how it compares to the Dayton. I still can't believe I ordered a ed sub and it came with this driver but that's water under the bridge.
