fuzzydog Posted May 28, 2017 Share Posted May 28, 2017 This would be a great combo for someone looking for a DIY project. I wish DIYSG offered Baltic Birch when I did my sub. http://stereointegrity.com/product/ht18-v2-subwoofer/ http://www.diysoundgroup.com/sealed-subwoofer-flatpacks/si-4-sub-flat-pack.html 1 Quote Link to comment Share on other sites More sharing options...
RoboKlipsch Posted May 30, 2017 Share Posted May 30, 2017 I surprised myself by realizing I just don't need one, or 4. It sure is tempting though with the inexpensive HT18 price, one could build a theater with 4 very inexpensively. How's the DS4 working out?

RoboKlipsch Posted May 31, 2017 Share Posted May 31, 2017 There's a great thread over at avsforum.com about these, google it and you'll see a lot of discussion they are frequently put into a diysoundgroup 4cft sealed enclosure, or a 5.4cft ported enclosure (or, a custom built much larger ported enclosure) They are very capable drivers and can play down to 20hz and lower flat in a large ported enclosure These are a cheaper alternative to a Dayton Ultimax 18, they don't handle as much power and the frame is not nearly as high quality but they work just fine About $130 cheaper than a Umax18 Quote Link to comment Share on other sites More sharing options...
Paducah Home Theater Posted May 31, 2017 Share Posted May 31, 2017 I guess I don't understand why they keep stopping at 4 cubic feet net. The popular drivers usually have 4 cubic feet as the recommendation after driver displacement which is what, 0.3 cubic feet or so. I'd have to model it to see how big of a deal it was, but still, what's the problem with just making it slightly bigger? Just seems like it would be misleading to some people. Also would be nice to state the cutout sizes or at least whether an Ultimax would fit it. Maybe they'll come out with a different baffle in the future if not.

RoboKlipsch Posted June 1, 2017 Share Posted June 1, 2017 Any bigger it takes 2 shipments, like the 4cft ported boxes i got. Quote Link to comment Share on other sites More sharing options...

It is the largest size and weight that fits into a flat pack box (two boxes I believe) that can be shipped UPS. I'm not smart. Erich answered that question on AVSforums.com. 2 Quote Link to comment Share on other sites More sharing options...

wvu80 Posted June 1, 2017 Share Posted June 1, 2017 Here's a great deal; a pair of 18's with flat pack for $400. It helps if you are located in Illinois. http://www.avsforum.com/forum/209-audio-gear/2843018-fs-2-dayton-audio-rss460ho-4-18-1-flatpack-460ho-um18-22-a.html Quote Link to comment Share on other sites More sharing options...

It's filling in the bottom octave nicely and blends well with my smaller Emotiva sub. I think I need to start running my sub amp in bridge mode though since I've seen the red clipping light start flashing in good demo scenes.

derrickdj1 Posted June 9, 2017 Share Posted June 9, 2017 It is ok for the clip light to blink on heavy scenes. If the amp gain is not on max, then it is hard to get the amp to full power since the gain control is an attenuator. You just don't want the clip light to stay on. I am assuming you don't have the filters with a large boost of 6 db or greater. The clip light may also be the limiter becoming active. I have 7 I Nukes and the clip light come on often throughout a movie on heavy scenes. Bridge mode will not hurt. Quote Link to comment Share on other sites More sharing options...
RoboKlipsch Posted June 11, 2017 Share Posted June 11, 2017 Ddj how about some pointers for all of us regarding attack and release settings? I admit i have no clue what they should be. Quote Link to comment Share on other sites More sharing options...
