Pete H Posted October 31, 2013 Share Posted October 31, 2013 I've tried searching the archives and can't find any good T/S parameters for the K48's and I need to get them to run some numbers on a ported and non ported double bass bin that I'm wanting to build so any information would be appreciated.

mustang guy Posted October 31, 2013 Share Posted October 31, 2013 Sounds like a cool project. A double Chorus bass bin. I want one! Quote Link to comment Share on other sites More sharing options...
Pete H Posted October 31, 2013 Author Share Posted October 31, 2013 It would be great.....................I think, if it wasn't so hard to try and track down the specs. I would imagine that the specs on the various Klipsch 15's are close and the DBB plans that JWC and Rudy and others have built would work for a front ported cabinet but I really want to spec this with the correct parameters and take a look at the dimensions of a non ported box too, but as of right now, no specs I'm going to try and reach out to Trey and see if he can help me out.

CECAA850 Posted October 31, 2013 Share Posted October 31, 2013 Just a thought Pete. Wouldn't it be easier to find a speaker that those drivers came in and just us those dimensions (cubic ft of box and cubic in of port)? Of course you'd be making a box with a tuning frequency of the box you're copying. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted October 31, 2013 Share Posted October 31, 2013 (edited) I believe my KP-301 II's have K48's (could be wrong nut I think that's what's in there). You could double those specs to make a dbb. It'd be BIG! Edited October 31, 2013 by CECAA850 Quote Link to comment Share on other sites More sharing options...
Pete H Posted October 31, 2013 Author Share Posted October 31, 2013 Hey Carl, Trey is getting me the specs but I'm sure you're correct and the 301's have the same drivers so 2 questions, how well do your 301's dig on the low end and what's your opinion of the sound? I totally get where you're coming from and that could be the direction if I go with a ported design. I did finally get to download winsid but it configured in metric so I'm going to uninstall it and try again. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted October 31, 2013 Share Posted October 31, 2013 I believe that the metric English option is selectable in the program. The 301's bass is clear and hits really hard with the right material. It's not to be confused with a sub however. Quote Link to comment Share on other sites More sharing options...
Marvel Posted November 1, 2013 Share Posted November 1, 2013 I believe that the metric English option is selectable in the program. That is correct. You click on the displayed measurement, i.e., metric, cubic inches, etc. and it changes. Bruce Quote Link to comment Share on other sites More sharing options...
bhendrix Posted November 1, 2013 Share Posted November 1, 2013 Here's an old sheet. I would think the K-45 might be preferred for a double-bass cab. Think KPT-904LF. K-1545:K-1548.pdf Quote Link to comment Share on other sites More sharing options...
Pete H Posted November 1, 2013 Author Share Posted November 1, 2013 Here's an old sheet. I would think the K-45 might be preferred for a double-bass cab. Think KPT-904LF. K-1545:K-1548.pdf Thanks for the information, I really appreciate it. I'm curious why you would think the K45 might make a better choice? When I look at the response I would have thought the 48, but I'm sure as always, I can always learn something. Quote Link to comment Share on other sites More sharing options...
bhendrix Posted November 1, 2013 Share Posted November 1, 2013 Nowhere does Klipsch use the 4 ohm K-48 in double-driver configuration. They, instead, use the 8 ohm K-45s, wired in parallel. The KPT-904, KP-450, and KP-456 all use dual K-45 in a ported cab. It will all depend on your design objectives. Quote Link to comment Share on other sites More sharing options...

I wonder if that decision was based entirely on the load it would place on the average amplifier and nothing else; but makes me think about this a little more.

Pete H Posted November 3, 2013 Author Share Posted November 3, 2013 I posted some items in the garage section that I need to get rid of and 1 set of the 250's is on the list and if I can find someone that wants the 115's with them then I'll just start with some new drivers but we'll have to see because I have no clue what the market is on the items I'm looking to move.
