denis johnston Posted January 9, 2022 Report Share Posted January 9, 2022 I would love the plans I want to build 18 pals been looking for plans my tops come down to 90 hz. I use 2- 6.5 speaker on a parallel lens and 1- 2 radian 950pb parallel lens and 4- 6338 McCauley 12 in each box and I have 4- 18 tapped horns by tom danely so I want more 20 to 60 hz sound thxz Denis Quote Link to comment Share on other sites More sharing options...

peniku8 Posted May 9, 2022 Report Share Posted May 9, 2022 @RicciHow would you feel about M-Drive in a Skhorn? Overkill unless you go IPAL? Quote Link to comment Share on other sites More sharing options...
Ricci Posted May 16, 2022 Author Report Share Posted May 16, 2022 Might be worthwhile if using the 21-ipals or the NSW's. Lots of $$$$ for that rig though! Quote Link to comment Share on other sites More sharing options...
peniku8 Posted May 16, 2022 Report Share Posted May 16, 2022 Yea, certainly good for a no-compromises build for maximum output density. I feel like the M-Drive should be powerful enough to drive two Skhorns when you load em with 22ds115's. I think I'll buy one to test, I need a good amp with the Powersoft feature set anyways. And I'd prefer active subs. Quote Link to comment Share on other sites More sharing options...
Father Francis Posted May 16, 2022 Report Share Posted May 16, 2022 try check the DigiMod 3000PFC+3000AMP with this you can use DSP-D and DSP-4 and add the big heatsink , https://www.powersoft.com/en/products/amp-modules/digimod-3000pfc i guess this would run you a pair Quote Link to comment Share on other sites More sharing options...

If you wanna use 2 21ds115's to the maximum of their capabilities you will need pretty much twice as much as the Digimods are capable of. I ran my FP13000 unlimited&bridged into the Skhorn (4R) no issues (music, not sine waves). That's a bit overkill, but I'm trying to run 4 drivers off one amp, which the M-Drive seems to be a good match for. Quote Link to comment Share on other sites More sharing options...

Art Beller Posted May 30, 2022 Report Share Posted May 30, 2022 Hi, been following for years. Lookin to build the highest density/efficiency/linearity system that will fit in my 8x8x6 garage in the back of my tour bus and with cabinets that can be carried by two people. Leaning towards split SK horns coupled with PM60's, lake DSP and powersoft or QSC amps. Chose the PM60 over the 90's so that my friends and I can combine for an array when we get together. Has anyone tried a setup like this or have any other suggestions on a top of the art DIY rig for bass music? Of course the paraflex community gets a lot of hype but by the numbers, I can't see how this wouldn't be better? Humble thanks. Quote Link to comment Share on other sites More sharing options...

Splitting the Skhorn in half results in a lot of driver pressure directed into an outer panel which I'm not a fan of. It really wasn't designed to be split in half because the driver arrangement is less than ideal for that. 1 Quote Link to comment Share on other sites More sharing options...

I dont have the possibility to measure them outdoors and need to use a new cab this weekend. All of the outdoor measurements with the Ipal's are posted on the main data bass page for the Skhorn. Have a look at the voltage sensitivity measurements. There is no processing on those and they are outdoors. Really doesn't need a lot of processing. Throw a 25Hz HPF on there and set the LPF where it matches well with the mains. They run pretty decent up till above 140Hz and the response is reasonably flat, so anything below that should be fine. The rest sorta depends on the mains, amps, environment and bass content ( limiting, etc...) Quote Link to comment Share on other sites More sharing options...
lawbadman Posted August 10, 2022 Report Share Posted August 10, 2022 Hello all, How would an 18sound 18LW2400 perform in this enclosure? I know its not the strongest woofer, but I would like to know if its worth it..... I plan to do some PA work and I have 4 of the 18LW2400 so I want to put them to good use. Thanks Quote Link to comment Share on other sites More sharing options...
chrapladm Posted August 12, 2022 Report Share Posted August 12, 2022 It doesnt perform as well as other drivers but it doesnt look horrible response shape wise. I compared my BC SW152's verse the 18LW2400. The comparison is 2400 is hitting Xmax and the 21 is at 8mm displacement. Only using this as a response shape comparison is all.

Ricci Posted September 4, 2022 Author Report Share Posted September 4, 2022 Yes. If using all vents open a 25Hz HPF is recommended. 1 Quote Link to comment Share on other sites More sharing options...

You'll cook a coil very quickly with that last 3dB of power. Just run a 4k or 6K plate one per cab and wire drivers in parallel. I’m in the process of building an skhorn right now, love the design, straight beast Just ordered up a pair of sw152 4 ohm drivers and I was planning on running them 1 channel each off my crown itech 12000hd, should get about 4000 watts per driver. is this too much power per driver or for the box itself?

Hello Shayne. That is a lot of power. Whether it is too much depends on a few factors. I'd suggest doing a bit of experimentation before running it wide open for long periods of time. Remember doubling power is only 3dB in an ideal case. 1 Quote Link to comment Share on other sites More sharing options...

Should be quite hard to kill the drivers due to thermal failiure with that in place. Many LMS don't support such long time constants though.
