Greetings to all 🙂I am green in these waters so please excuse my ignorance. I am planning on building the bass bin cabinet design using the Precision Devices 186 horn, the plans for which are available on Speakerplans.com. I recently got my hands on Carvin 100W bass amp and I was wondering if this could be a suitable companion to the bass horn in order to round the two-piece, mono system out.
The PD 186 horn is rated at around 95 dB and from what I can tell the Carvin amp easily puts out that much, granted at the lower frequencies it suffers and in order to safely obtain max volume I need to cut the bass, hence building the bass cabinet. What concerns me is that the 900w cab will overpower the amp above it. That said, if i am correct, it takes more wattage to power lower frequencies at the same SPL.
Here is a clip of the amp alone in action. To your knowledge, could it serve as a PA speaker in tandem with the PD 186 driver?

Also would I want to cross over / route the mid and high frequencies to the lower watt amp and the lower freq to the higher watt bin? Thanks 🙂

No.. that's not gonna work. That 186 horn is rated at 105dB assuming you are using one of the recommended drivers, and that is what it produces with 1w input, with 1000w into it you will need a serious PA cabinet with quite a bit of power behind it to keep up.. something like the X12 with an amp that does 350/500w per channel for example. And yes you will need a crossover to separate the highs, mids and lows and some EQ too so you should be considering a PA processor like the Behringer DCX 2496.
That video you linked is terrible by the way.. I can't see anything in it. Posting videos of speakers and audio equipment is totally useless anyway.. just post a still picture of the item in question.

nor can a 100 watt Carvin amp be considered a bass amp (except for practice or small basement jams)
i bet five bucks that if you built the PD 186 bass horn and ran that poor little Carvin into, it the flyback voltage from thumping the low E on your bass would kill the output stage of your amp pretty quick.
and if your thinking of using this amp as a DJ type system i predict a fire!

You would damage the woofer too most likely, the amplifier will lose control of the speaker causing the voice coil to overheat. I guess you could compare it to stalling a cheaper power drill and run it at minimum speed. Pretty quickly you'll see smoke.
On another note the 186 horn and the 1850 horn are not what you choose to have just ONE of. Min 2 per side to get low response. If you can afford 4000w worth of power amps (and don't say behringer) pretty sure you can use the Eminence omega pro 18 driver in this cab and its quite affordable

Gonna pick this up.
The first bit makes no sense at all. This is a serious driver being connected up to a not-so-serious amplifier. The only way the amp might kill the driver is if the output stage dies and shorts the speaker output to one of the PSU rails. "Losing control" just doesn't happen.
The bit about amplifiers is just misinformed. You can check out the bench test of a Behringer amp here: Behringer inuke NU6000 vs KAM KXD7200 bench tested - Speakerplans.com Forums - Page 1

Plenty of cheap power IMO.
