Would also allow someone to start with two and grow to 4 by adding a second amp. This would also allow you to do a 2x4 mini and the ability to EQ all four subs independently. I also like the non-pro inputs in that setup.

Not trying to say its a better setup, just looking to get your feedback and help me find fault with my logic from those of you who have ... traveled this path before the rest of us! smile.gif

the actual measured output of the ep4000 is much lower than the specs. those are more like peak numbers. real output at 4 ohms is 650 watts per channel. check out this thread. the ep4000 is the same as the ep2500. http://www.avsforum.com/t/855865/measuring-amplifiers/0_100#post_10753638

the EP4K is a good match for a pair of SI 18 D4 since you can wire them as 2 ohm stereo or 4 ohm bridged and get good power to them

the CV5000 reaches its stated specs and is a better match for these drivers to get the max power to them.

^^Ugh .. and many thanks wink.gif So the CV is back on my list .. was just looking for an option to have four eq points (ie, 4 channels). What about the inuke DSPs .. any pair well with (4) 18HOs? I like the inuke DSP interface (played with a 1000DSP at a friends and it was pretty easy). For the price of the CV and miniDSP you can get two 3000DSPs, but I can't find RMS like numbers for it.

Am glad you chimed in about the Daytons from PE, they are suppose to be in stock today but aren't showing up yet, I was wondering how long it would be. Regarding your prior post, you seem to imply that the cv5000 can't be used with four subs, I hope that is not the case because I just ordered mine last night!

the CV5000 is perfect for four Dayton HO's.

im not familiar with the iNukes but from what i have read, they do not perform as well and actually roll off earlier on top of that

I've owned the CV and the iNuke6000DSP. I wouldn't say it was a poor performer. Just didn't do what I wanted it to do.

The DSP on the iNuke is awesome. However, the iNuke are very over rated as well. The 6000 is basically two bridged 3000's strapped together. If you bought a 3000 expect about 900 watts stereo @ 2 ohm or 1,800 watts @ 4 ohm bridged. I'm on my cell so I cannot track down the bench tests that have been done for the iNuke. Sorry.

I've yet to see the CV on the bench, but having owned one and using it to push the same setup, my subjective thoughts were that it was much closer to spec than the iNuke.

not sure what is over rated about the inuke 3000.

spec:

NU3000:
RMS
Stereo
8 Ohm per channel, stereo 315 W
4 Ohm per channel, stereo 620 W
2 Ohm per channel, stereo 1040 W

Bridged mono
8 Ohm 1250 W
4 Ohm 2075 W


measured:

With resistive loads, power output at clipping was pretty darn close to:
300Wrms/8ohm/channel
600Wrms/4ohm/channel
1000Wrms/2ohm/channel

2000Wrms/4ohm/bridged

http://www.diyaudio.com/forums/class-d/213071-behringer-inuke-nu3000-measurements.html

http://www.behringer.com/assets/NU1000_NU3000_NU6000_NU12000_NU1000DSP_NU3000DSP_NU6000DSP_NU12000DSP_WebBrochure.pdf





here is the 6000 bench test:

http://forum.speakerplans.com/behringer-inuke-nu6000-vs-kam-kxd7200-bench-tested_topic69202_page1.html

spec:
Stereo 8 Ohms per channel: 1500W or 1100Wrms
Stereo 4 Ohms per channel: 3000W or 2200Wrms

To summarise, for music signals, both channels driven, you can expect an output of:

Behringer:
1.37kW into 8 Ohms, 2.05kW into 4 Ohms for full-range or mid-top duty
1.16kW into 8 Ohms, 1.80kW into 4 Ohms for Bass duty

and around the impedance peak in the bass, "power" is likely to be higher.

I hope my intel was good, but its not comforting that PE just updated the expected date to 6/18!!!! eek.gifeek.gifeek.gif

I'm going to call to confirm again tomorrow ...

and around the impedance peak in the bass, "power" is likely to be higher.

Thanks for finding the bench test links LTD! I based my comments in the context of someone wanting to arbitrarily use the peak numbers provided by Behringer, as paulyc did when he was trying to compare the EP4000 to the CV5000. Just wanted to make sure he wasn't expecting 1500W per channel @ 2 ohm, etc... from the iNuke3000.

Also, I must admit that I never took the time to cross reference the iNuke3000 bench with the iNuke6000 bench. They seem similar, but a bit different. My major take away from the iNuke6000 bench is bolded in your response above. Seems to be less power on tap for "Bass Duty." I didn't see you make a pointed reference to the iNuke3000 regarding Bass Duty and admittedly have not checked the DIYaudio source you provided.

I'll try to make time to do that today.

How do I hook my subs up to this? Stereo,parallel? What about the wiring? Will two of the sub be slaves?

does the SMS-1 have the ability to EQ two inputs as one?

as for the wiring, you will wire two subs in parallel for each channel. that will make a total 2 Ohm load per channel. 2500 watts. so 1250 watts per sub.

So for parallel I'm going to run speaker wire from the p/n of one channel to two subs and a wire on the p/n terminals between the two subs, right?

The negative will go to both negatives. The positive to both positives

Scroll down on this link and you will see two 4 ohm subs wired into 2 ohms

Any particular way of putting the polyfill in, or just shove it in randomly? Also, I guess the wire inside has to hang a little loose, so i'm assuming that is no problem?

just stuff it in. try to float the wire in the pollyfill a little to avoid it touching the sidewalls as much as possible.

Thanks buddy! I am a bit mechanically challenged so anything you deem challenging or significant would be appreciated. What amp did you decide to go with?

I`m in the same boat, but my desire to tinker around with stuff is usually greater than my knowledge so sometimes I just jump in, sometimes it works out, sometimes, not so much:) I went with the Cerwin Vega 5000.
