Title: OK, one big question needs answer... Post by cavenut on 11/07/06 at 13:36:37 Thanks for all your advice. The big question left is: Do load it with the magnets facing each other in the middle? OR, do I load it with the drivers both facing the same direction? If so is that up or down? Thanks Again you HouseWrecker Guru's, Michael |

Title: Re: OK, one big question needs answer... Post by Adrian D. on 11/07/06 at 14:10:49 try all the combinations. most used combination is with the magnets in the middle chamber because it reduces the volume in the center chamber, improving control and coupling between drivers. |

Title: I am starting to wonder if... Post by cavenut on 11/07/06 at 15:51:50 I am starting to wonder if I should through caution to the wind and just go with four drivers. The only thing that I am hesitant about is the $800 price tag for four of these drivers. http://www.partsexpress.com/pe/pshowdetl.cfm?&Partnumber=295-420 I already plane on using 1-1/8” MDF for the damping factor. I have no plans to modify the original plans, except for using PVC on the 6” x 8” port. Also Using a 4” x 2” PVC for the bottom ports, this only to give it a finished look. I figure that with Wood, Screws, (4) Drivers we must be at 200+lbs. I have all tile floors so I will also need to add a set of leveling feet with rubber bottoms. Anyone know of any problems with these Small Modifications? Thanks in advance, Michael |

Title: Re: OK, one big question needs answer... Post by Bob in St. Louis on 11/07/06 at 17:41:20 Michael, I'd go with (2) drivers for now, magnets in center. Did you look at my pics? I've got HWK "in process" pics that shows one of my mods regarding driver mounting, and placement. The mods you have listed would be fine. I don't see a problem. Here's a couple threads I started a while back. (I'm a fellow Housewrecker newbee). It's a lot of reading, and some OT stuff, but there is quite a bit of good info in there. You'll also see/meet some of the guys that helped me. It's a good place to learn. The beginning of my quest: https://www.decware.com/cgi-bin/yabb/YaBB.cgi?board=Housewrecker;action=display;num=1137542099 This one starts out after I've had the sub for a few months.: https://www.decware.com/cgi-bin/yabb/YaBB.cgi?board=Housewrecker;action=display;num=1145573673 Bob |

Title: Re: OK, one big question needs answer... Post by Bob in St. Louis on 11/07/06 at 17:43:55 By the way, this is very important. When you wire them, make sure they are all pushing/pulling in the same direction. This is accomplished by wiring the ones facing "the other way" out of phase (+ to - and - to +) Know what I mean?

Title: Re: OK, one big question needs answer... Post by cavenut on 11/07/06 at 17:58:13 Yes I do know what you mean. Wasn’t that a line from “Young Frankenstein”. Did you build with two or four? Michael |

Title: Re: OK, one big question needs answer... Post by HT-EXT on 11/07/06 at 18:14:14 Welcome Michael. If you go with the Titanic line, two should be more than enough. You might want to look at the Series IIs from Dayton for a cheaper alternative. I use the Series IIs but have found that my HWK15 sounds a little better laying on its side. Also the magnets in the center chamber seem to play lower than the other set ups and is my favorite for the HWK. Good Luck. HT-EXT |

Title: OK Bob here is a question.. Post by cavenut on 11/07/06 at 22:17:06 In the center between the magnets you have some spacers. are they necessary functional or are you just experimenting? What do they do? Michael |

i believe they kinda join the 2 drivers together to make them behave more like 1 driver. or bob has a weird drink mixing system in his ht bar? |

Title: Re: OK, one big question needs answer... Post by Bob in St. Louis on 11/08/06 at 11:09:41 I just spent the past 40 minutes typing up a nice eloquent, informative response to your question Michael. After I clicked "Post", the site told me I'm not a Member! It lost my post. >:( It was long too. When I get over this white hot pissed hatred of everything on the planet, I'll make attempt number 2. |

Title: Re: OK, one big question needs answer... Post by 60ndown on 11/08/06 at 13:36:13 oops not tripple thick just 'battons' :'( im curious bob, i saw you and the guys modding your hwk for a few weeks, trying to get it to be right for you? in as few words as possible how did it turn out? what differences in performance to the typical hwk does yourz have, and now you have had it up and running for a while do you think its right for you? i have also had long posts deleted by the computer gods, thats EXACTLY WHY i keep posts short nowdays, i hate getting that pissed off over something so silly ;) |

Correct. 60, it made it 'boomier', but for HT use, that's exactly what the doctor ordered. Slightly less musical depending on the music your listening to. If you crank up Nelly, Eminem, ect... it sounds great. If you crank up some smooth jazz, it's a little "one notey". I'm trying to learn, that when I write a big long post, I'll right click it, and copy. That way when it goes in the "internet toilet", I simply 'paste'. It's worked a couple times. I just smile knowing how pissed I could have been at that moment. In fact, this post is getting a little long. I think I'll copy it too, just in case. Bob |

Title: I am definetly not looking for boomy Post by cavenut on 11/08/06 at 16:46:42 I want the bass to be somewhat tight, but I also want low Hz. Are these two things not possible to get together? By the way bob my little trick is to write on a word doc. then copy / paste to the forum. Saves time on spell check. I am one example of the mid 60's private school phonetic learning experiment that failed miserably. Hence I am one of the worst spellers, with four college degrees. |

Title: Re: OK, one big question needs answer... Post by Adrian D. on 11/08/06 at 16:52:17 musical and really low aren't easy to get in the same package. choosing the design is dictated, imo, by what you want the sub to play. |

Title: Re: OK, one big question needs answer... Post by Bob in St. Louis on 11/08/06 at 17:33:52 Cavenut, It's 'close' to possible to get real low and tight. Might be better to pick one. (Is sub for HT or music?) You may have answered in the past, but I can't remember. I built the sub for movies, THESE GUYS got me into music. ::) So maybe my tastes have changed a little. I'm currently into OB for music (and movies) I'm looking for a better sub now that would 'mesh' well with music. Soooo, with my 'new tastes in hand', maybe this sub is too boomy?? It falls under the category of 'your tastes', you might like it? Know what I mean? ;) Bob |
