can someone please help me find specs for a mini boominator - my eyes are too tired to keep scanning through this thread and the search doesn’t find a separate thread
thanks
thanks
After reading a couple of pages I've finally decided to go for a full size boominator with HP-10W and PHT-407N due to the better audio quality.
I'd say that I dont really have a budget, so if thats the case what would be the best to go for? Are there any other alternatives?

Seems the p audio 407N tweeter has gone out of production. At least I can't find it anymore. The 407 is still available on ebay.
This may be a big ask, but can anyone help with what the crossover would need to be? The 407 is 2db less efficient.

Still available here atleast according to the site. Could be expensive shipping though..

Yeah I see it overseas but haven't found it yet in the US.
I did find another thread where Saturnus said the same filter could be used with just a different resistor value. If anyone can help with that value I'd appreciate it.

Btw I responded to your PM. Everything I have is US / imperial based so not sure if you are interested.
I found an online calculator and I think you'd need a 2 ohm resistor instead of a 4 ohm. I don't know what I am doing so if someone can verify I'd appreciate it. Thanks.

Just finished cutting out all the pieces for the boominator. Did this using a circlesaw and im very satisfied with the result. Will be uploading more pictures later on.
An externally hosted image should be here but it was not working when we last tested it.
I have these tweeters I ordered with my HP10W's, I'm not sure what they are though. The supplier told me "they are a generic Asian copy and doesn't have
a model number as such. We call it a P105"
Will these be OK with the standard 47ohm 3W resistor?

That is a piezo tweeter.
I would connect a series film cap to its + and parallel (tweeter and cap) to the woofer.
Try something like 470nF to 1uF.

I've read through most of the thread and I'm still a bit confused on the rounding over. Do I have to round over the front baffles and port holes / handles only? These are the only parts that could be rounded over with 12mm as far as I understand.
What about the center brace cutouts? I've seen photos of those being rounded over as well, but with something like 4mm instead of 12mm. I feel it would be impossible to round over center brace on both sides with 12mm.
These look identical to PZ1005, however frequency response appears to be different. PZ1005 has 4-27khz. I don't know if the resistor would apply.
Does anyone have original Saturnus' boominator photos from the first page? I was able to recover only 3 photos using web archive 🙁
Impedance and other things
I'm going to Roskilde this year, so we are planning to build a setup using 2x Cubo 15 and 2x halfinators with pht407n as tops.
Unfortunately I bought the 2013 model of the bassface DB4.2 which has a fixed HPF @ 80 Hz with a 12 dB / octave slope. I guess it's fine enough, although a bit higher crossover point would have been preferred.
The bassface DB4.2 is stated to be stable at 4 ohm bridged, but I can't understand the filter schematic for the HP10W and PHT407n (both are 8 ohm nominal), it should be 4 ohm, but since all of the speakers are connected in parallel shouldn't it be 2 ohm? Has it got something to do with the resistor? I intend to use a 15 watt rated resistor instead of a 5 watt as the bassface 4.2 outputs around 200 watts RMS in bridged mode.
The bassface will supply the 2x Cubo15 with a crossover at around 90 Hz since it's only a 12 dB/octave slope.
Do you see any problems in this setup? Filter schematic is attached.

Qubinator help
Guys,
After long research I decided to build a qubinator. Apparently this gives a better audio experience than a halfinator - and is cheaper!
Currently looking for HP10T drivers, but cannot find a supplier! Does anybody know a even-worthy alternative?
Should be a full-range 10" driver.
Greetz from Belgium!

You've got it right. The 12 mm was specific to the baffles. Saturnus had reported that the specific value was chosen to tune a minor aspect of the FR. The port handles and center braces should have 6 mm round over for the HP10 builds.
Goldwood GW-108 and Basslite S2010 are the only other options that were 'approved' and required use of PHT-407N tweeters. They each had some differences in the build and I don't know if they were discussed at all for qubinator builds. I'm a but surprised you can't find the P-Audio drivers in Europe. Historically that is the only place they were readily available.
