I been looking at DIY subs. I looked at building dual 18" subs and it came out to be less than $1300. Am I missing something?

RS18 + flat pack X2 = $650

NU3000DSP = $400

I dont think assembling/finishing is going to cost $250.

I just saw I can buy the cabinet and sub for 325. Then I can do two and use the ep4000 for both. I plan on doing 4. So that will be $2060. I hope assembly and finish will cost no more than $140 to bring the cost to $2200. Maybe I should go with a 5.4 setup at first

But then you can't EQ/XO. Need a DSP amp/box for that.
Some AVR's are fancy enough to do that for the singular LFE channel I suppose...

the Inuke 3000dsp should give him enough umph for both subs + those features

So that's better than the ep4000?

It basically puts out the same power, and has full DSP control down to 20hz, for $30 more then the 4k.

They are basically the same amp.
Only difference is the EP series has SLIGHTLY less low frequency roll-off.
While the Inuke has the option to buy as a DSP version allowing EQ all in one package. (i own one of each)

yea cant go wrong with either amp. i use the EP4k because it was on sale for 279 with free site to store shipping last year biggrin.gif

Dual SI 18s will save you a ~$100 over 2 of the daytons and sound basically identical

sheesh, I remember that. I ALMOST picked up one last year for a future project but didn't have the cash. I have 2 THT's that are monstrosity's but I'd love to do dual 18 sono's to get a bit lower than 22-24 hz.

but then you don't get the deal on the flatpack, which saves you $120.00

so in the end the SI would be $20.00 more for basically identical sound.

I know, I looked that up. Basically, dual 18" Dayton subs will cost me a maximum of 1200, maybe even 1150. That's with the Inuke3000 dsp. If I did just the Inuke3000, I could save $100

No reason to mess with the iNuke for a sealed setup, stick with EP4000 even if you have to find EQ options elsewhere (which likely would be better anyway):

http://www.avsforum.com/t/1435795/first-diy-project-for-a-guy-looking-to-upgrade-multiple-sealed-18s/900#post_23080227

It rolls off at 10Hz and fairly steeply. The EP4000 does not do this. Your electronics chain has enough roll-off in it already, you don't want to pile on.

Thanks for the info. Good thing I'm not starting to build until Sept when I get my place. My first HT upgrade is my dual subs. I still haven't decided on speakers yet

Are we actually forgoing otherwise reliable, well-performing sub $300 amplifiers because they roll off in the single digits? Especially so in regards to relatively modest arrangements like these that may even benefit from some 1-9hz nose-diving? Wow. Ok I guess.

Actual phone call (see pic to left):

 

Tech (responding to laughter): "I'm sorry sir, did I miss something?"

Me: "Yeah, a case of Diet Mountain Dew walking across my living room."

I don't start my build for a month, so all help is appreciated. It gives me time to look everything upand rresearch to make the best purchase

How is the EP4000 not a reliable well-performing sub-$300 amp? You've already got roll-off in your chain, no need to pile on a 10Hz nose dive too. If you've got cabs and drivers that can give you single digits, why not feed it? Just seems like a waste.

well its generally not sub 300 unless you find a good deal one one. but the amp is pretty much bulletproof.

True, I just looked up Amazon's history and the lowest the NU3000DSP hit was $340, the EP4000 $240.
