Thanks!

Yes I think your right; I bought the design from argent, and those are the specs. when you say 'low end', how low are you speaking of? I'm not familiar with 4th orders, and the 'high' tuning scares me. Any idea where I should set the subsonic filter/high pass to protect my driver? (12'' dc lvl 4)

I believe what the dealer(s) were trying to say is that compared to major companies and corporations, sundown is a small company. I don't think sundown is incorporated, which means if anything happens to jacob, Sundown goes poof. Although I'm a big fan of sundown, I think your local dealers have a point. If they sell a kicker amp, and someone has a problem with their kicker amp and brings it back to the shop, the shop knows that they can either fix the amp and get reimbersed by kicker or just send the amp back to kicker and get a refund on it. Although they could do the same thing with Sundown at this moment, If sundown is bought out or goes out of business, the shop won't be able to go to them for warranty information. Now I know that sounds a little hostile against sundown, but theres really no way to tell how it would play out, until it plays out. So the shop owner has a valid point. As for him getting angry, Imagine if someone walked into your store and said why don't you carry xxx brand, I won't buy your stuff because you don't sell xxx brand, xxx brand is better. Its like a kick in the balls, and if anyone else is around to hear you I bet they're going to go home and look up xxx brand instead of buying something right away. Just not a good issue to press.

not sure i follow why you posted that? I think you have this thread mistaken with the 4th order caviler thread.

Ah well I'd like the box ported into the cabin, with the trunk sealed off. And I'd like a lot of low end dbs, anywhere from 15hz-40hz, the lower the better. I have a google sketch of the box drawn to scale, so it has all the measurements.

I had a 4th order bandpass box designed for me, but he didn't give me an output graph or tuning frequency or anything else. So before I build the box, I'd like to know what the output graph looks like (if there are any high/low peaks/dips in the curve at certain frequencies). How can I figure out what the 'range' of the box/sub is? I'm not sure how to ask this, but I'd like to know the frequency band width. Whats the lowest the sub should play and the highest the sub should play. So I know where to set my subsonic//lowpass filters. Can anyone help me? Let me know what measurements you might need or just tell me how I can calculate it.

would the 2runs of 0g into one amp make the amp draw current more efficiently for a smaller amp? Like one of the sundown 1200 v2s Sort of like how 'bigger is always better'. ???? if so, if you could show some test figures i'd defiantly be interested in this.

I read your article; according to sundown's figures, their amplifiers efficiency rating only changes by a few % when comparing 1 ohm to 2 ohm to 4 ohm loads. So is it pointless to power a sub with an ohm load over 1? is there any real advantage to getting a more expensive 2 ohm or 4 ohm load amp for a sub? (well, for my sub i'd say) Basically, what it boils down to, bottom line, what I need to know.... this is my system, please give me your criticisms, be as judgmental/helpful as you can : 80amp alt spv70 stinger bat in the trunk random duracell batt under the hood 0g connecting the batts, big 3 in 0g alpine 9887 (main source is ipod connection, mp3s) hertz 165 mlk comps powered by a ZED kronos, ran through a kicker 2ch 31 band EQ dc lvl 4 12'', powered by ??????, box tuned to 31 hz, 2 cf Audio control epicenter between the sub amp and the hu. I listen to punk-pop-rock, classical, and some rap. bands like: senses fail, eminem, mozart, bach, etc. I like listening to loud music without distortion. I like feeling the bass.

Explain what you mean by "I figured it would reproduce the 100hz area down in the 40 hz area." Are you saying you think it would transform the 100 hz notes into 40 hz notes? If so, no, it does not do that. No, I mean reproduce as in copy the notes and play them at a lower frequency. Sort of like lets say you play A B D on a piano starting at middle C; well the epicenter plays A B D at the same time that the previously mentioned A B D is played, but at a lower frequency. Correct?

when you say you 'never felt the bass was worse', do you mean that in a good way? like the bass was 'sick' ? or do you mean the bass felt terrible (in a bad way) ? At 650w @ 4 ohms it sounded good, at 1000w @ 1 ohm it sounded bad, so are you running your saz1500 @ 4 ohms?

well I just googled regulated vs unregulated power supply and read a few articles and I must say I am confused as ever. I haven't connected the epicenter yet, so I'm not sure what it sounds like. But i'm interested as to your experience with them ///m5 what epicenters have you heard/used? can you describe why it'll make things worse? I figured it would reproduce the 100hz area down in the 40 hz area, as the rock songs I like don't typically go down that low (so the sub is virtually useless for those songs). I've read that many people think that epicenters make the bass 'muddy'. I think one could associate this with the subwoofer's inability to stop itself and produce the next note accurately. So wouldn't a higher dampening factor solve this issue? And of course, doubling the ohm load twice drastically increases the dampening factor. can someone make up some percentages for me on efficiencies comparing regulated // unregulated and 1 ohm // 4 ohm?

I have a 12'' dc lvl 4 in a box; 2 cf tuned to 30 hz. I have an audiocontrol epicenter which will be replicating fast-paced bass down to the subwoofer level (rock music). Would it be worth it to run the sub at 4 ohms as opposed to 1 ohm? 1 ohm would of course be cheaper, but would I notice much of a difference (considering the bass will be rather fast-paced) if I bought a 4 ohm 1000w amp? what amp would you guys recommend? I know a DC sub isn't the best choice for SQ, but I already have it frontstage is a pair of hertz mlk 165's powered by a ZED kronos alpine 9887 hu.

any more news? the suspense is building up! I can't wait to get my kronos

any ETA?

Sorry about that >.> I feel like an ass for asking that. I just read the entire manual (all 40 pages of it...) and I have a few questions He mentioned that 1000w at 1 ohm is like 4 db louder than 500w at 4 ohm. Does this imply that 1000w @ 4 ohm is louder than 1000w @ 1 ohm? or am I a bit confused here? Also, what type of board is the kronos made on? double sided? etc? Lastly, I'm curious as to why the feature that constantly analyzes the ohm load of the speakers is beneficial? Correct me if I'm wrong but, basically what it does is tell the amp that instead of there being a 3.5 ohm load, there is a 3.7 load because of the voice coil heating up from playing. Is it that big of a deal? Can someone explain this to me? Thanks When is this group buy being closed? I plan on getting a kronos within the next few days.
