I'm looking at buying a UXL18 and a 4 cu ft flat pack from DIY sound group but what amp will I need? I'll likely end up with two of those subs one to start then another one later. Also, what else is needed? Is that all there is to do? Put the box together slap the sub in and done? Is there no tuning or anything? Also, how do you finish the box? If I wanted a bamboo veneer do I just bring the box to a local veneer shop and get them to put it on? How do I power the sub and connect it all? Is there somewhere that explains all this? Yeah I'm this new hahah

You could power both sub's with a inuke 6000.

How much does an EQ cost?

So inuke is a good amp? I see its a class D? Is that going to be better than class ab?

The minidsp is real popular
http://www.minidsp.com/products/minidsp-in-a-box/minidsp-balanced-2x4

The inuke has a model with a DSP that can eq to 20hz. Lots of people use the inuke series for sub duty and I haven't seen a complaint about them other than fan noise. Most pro amps are noisy so home theater users will replace the internal fans with quieter ones.

Cost adding up..

$120 for box
$530 for sub
$500 for amp
$195 for EQ and mic
=
$1345

Ahh I guess that's not too bad, about the price of a Rythmik FV-15HP

Plus the price to get box finished in Bamboo... Is that hard to do?

I guess the big price saver will be when I add the 2nd one.

What about quiet amps? Is the fan pretty noticeable?

Do I still need the EQ if I'm using an Anthem MRX with it ARC? Wouldn't that do the EQing ?

I'm not real familiar with how Audyssey or ARC works with low frequencies. I think it measures the F3 of the sub in room then Audyssey won't apply any EQ below that...Once the subs are in room, you might gain some spl down low because of room gain. I say you try without an EQ and if you feel like its lacking down low then go ahead and buy an EQ and microphone to measure.

Ok so is this how I'd build it...


Glue box together
Drill a hole for wire
Insert sub
Connect sub to amp
Run EQ
Done?

Is it that simple?

I guess I should add dampening too?

And since the amp is powering the sub the sub wouldn't need a power outlet?

A single UXL-18 in a 4cuft enclosure with an iNuke6000 and MiniDsp for the lows will likely outperform the Rythmik by a good bit, and when you add a second UXL-18, well then you will likely outperform the Rythmik by leaps and bounds!

Go with the iNuke3000 if you can't afford the iNuke6000. You can find the iNuke3000 for under $280 all day long!

Use speakon instead of just a hole (it's well worth the extra few bucks).

You will also need an RCA to 1/4 TRS wire/adapter; and a speakon cable.

The DSP amp has the EQ and XO built in, you don't need to have two EQ's. So that saves you some money.

What mic are you talking about? You will need both an SPL meter and a measurement mic kit. (You can d/l for free a basic SPL meter software for most smartphones these days, not ideal, but that would do in a pinch.)

Most silent amps that are also good, are also very expensive; or very cheap and crappy.

The mini DSP had a add on called UMIK-1, I'm assuming that's a mic for measuring?

So when the boxs is done I just run a wire from the back of the sub to the amp? I use a speakon insert, is that to keep the box sealed from the hole for the wire?

Speakon insert looks like a good idea, so I hook the sub to that then I use the cable that runs from the back of the sub to the amp?.

The box needs to be sealed so you'll need to use binding posts or a speakon connector w/mount.

You can get a pair of binding posts from diysoundgroup.

And Do I connect the sub from the inside with a Y? Then I connect wire from both red and black to the amp? Then I use the LFE on the amp to the avr? Is this correct?

So is the benefit of a Rythmik kit be that I don't have to EQ it? I'm guess its more plug and play? Or do I still need to do that?

Every room has a different response curve, so every system needs EQ.

So what's the difference from a EQ like minidsp vs ARC in the Anthem MRX?

Is the mini dsp hard to understand and use?

The ARC in your Anthem is for people that want to basically plug and play. It probably works reasonably well at somewhat smoothing out the response, but the MiniDsp is a much more capable unit. The ARC is only going to do so much. I am sure that all receiver manufactures would love to have a more capable EQ in their receivers, but the reality is that it would be way to complicated for the average Joe, and likely hurt sales if people had to learn all of this stuff when they can just buy another receiver and have a plug n play room correction built in.

Think of DVD MiniDsp as a way to improve upon what the ARC will do in your Anthem. Keep in mind that most room correction in the receivers, such as ARC in your Anthem, only have very limited ability to EQ the subwoofers. So to get the best sound from your subs, you will need a MiniDsp to EQ them properly. Especially if your sub(s) are sealed. Hope this helps!
