Yes you can if you want, but the slightly higher tuning is not much to be concerned about if you plan on crossing over at or above 80hz.
These are probably be the best ones to use with it: https://www.parts-express.com/speaker-cabinet-port-tube-1-1-2-id-x-4-l-flared--260-402 Those...
Yeah the stock crossover will work fine if you wanted to use the passive radiators. There is little difference in cone excursion between the...
I ended up getting a few PCB's made for the new crossovers, if anyone is interested in those let me know. They are designed so the you can use...
Yeah right now the easiest options are for either a 4 ohm 8" MTM ~98dB/2.83v - 95dB/1w, using two of the 8 ohm woofers from the HTM-8. Or a 10"...
You don't normally run into IM distortion issues when high-passing at 80hz. You have to be cranking it and have a lot of bass heavy content to get...
It should work fine for that. You could possibly get away with a 7" high baffle if you used 1/2" material for the top and bottom, or 7.25" if...
It will be an MTM, still deciding between dual 8" and dual 10", and between 4ohm nominal or 8 ohm nominal. If you had to pick what would you like...
This is a common issue if you tried soldering to the coated part of the wires on the inductors or coils (usually red or gold colored). You need...
The midrange chamber is meant to be filled with some kind of damping material leaving just enough room for the drivers. I used recycled denim...
The HTM-12 could certainly be built sealed, general enclosure size should actually remain about the same as the regular ported version. The bass...
We discussed adding them but it hasn't moved forward beyond that. In the mean time I have added the new crossover info for all the designs as...
That isn't too close, because of the crossover points and driver spacing integration distance on the horn is similar to something like the...
Cabinet is 12.5" wide x 16.75" high x 7.5" deep. Sensitivity is 94dB @ 2.83v Crossover is 1300Hz approximately 24dB/octave electrical. +-3dB...
It's hard to explain because the frequency response and distortion are really close between the two designs, CD in the 615LX is slightly smoother...
2018 update: TM and MTM designs likely getting revamped over the next few days.

The Magnum-12 requires very little if any DSP for the smaller higher tuned enclosures. The DSP was only used to boost the bottom end on the low...
This is the only schematic I have from that design: [IMG] If you looks close you will see that the 150uF capacitor is connected across the...
You should use a modeling program like WinISD or hornresp to plot the SPL of the subwoofer driver in question. Depending on the enclosure type...
