QSC K series best diy alternative?

#1 Post by SCStephens » Thu Jul 20, 2017 11:45 am

I have been reading through these forms for quite a while and finally signed up to ask this question. I built a horn ht sub based upon plans found in an old audio magazine last year before finding bfm/these forums and am a bit hooked on diy speaker building.

At an outdoor gathering a while ago, one of my friends, who sells pro audio, brought a single qsc K10 and I was thoroughly amazed at the sound/outdoor fill of the single speaker. I have had the thought that "I can probably do better using a bfm design"? Single onmi 15? Jack series? I'm not looking to build a concert setup, but yard filling sound would be great. Recommendations? A single K10 runs ~$700, can I blow it away on price, sound, both? I already own an inuke1000 from my giant sub if I can put that to use. Thanks in advance!

A Jack 10 or 12 with a CD horn should do quite nicely. I like my Otop12's but their low end falls off faster than a Jack. They work great with my T39's If you are not considering subs I would build a Jack or probably two.

+1

If you are going to use the box stand-alone, then definitely go with a Jack. If you will always have a sub going at the same time, then build the OmniTop 12.

For the price of the QSC, you can build 2 OT12s.

6 - T39 4-25" 2-22" 3012LF
4 - OT12 2512 Melded/NSD2005
1 - T24
2 - XF210

SLA Pro and Simplexx 10 and 12 are other alternatives, and both require minimal, if any, EQ.

I wondered if I may have been barking up the wrong tree, best bang for the buck? I'm planning on buying the whole set of plans to have some reading material and future projects. Thanks for the input, I love that you guys are so quick to answer questions including the man himself :D

Hate to follow my own post, but a SLA and a tuba sub is looking like it might be a pretty sweet combo; So many options.

That would be a DR, which has the highest SPL output with the lowest build cost. The downside is the build complexity. SLA Pro is the easiest build, but the most expensive per dB SPL because of the number of drivers used.
