We never really pushed them too hard only up to about -12 or so on the AVR and according to the inuke software the output level never really exceeded -15dB on demanding material so they will easily...

I'd just run all your 220v quested amps off one 20amp circuit. At that voltage you've got about 4400w of continuous load on that circuit before the breaker trips and likely a good amount of headroom...

This, you have a short somewhere if the AVR goes into protect mode, either along the cable somewhere or at/in the speaker.

The completed crossover boards would be an additional option for the kit (like the flatpack). The kits will likely come with PCB's in the future like the Volts do once Erich can get the boards made...

Yeah you solder those in. I normally apply a little hot glue just to hold the terminals onto the board when I flip it over to solder but the solder does most of the work of securing them to the board.

I just tested it with sine waves and tone bursts while dialing back the limiter until I stopped getting bad noises out of the driver or amp. IIRC at the 30hz tuning it was amp limited as the 84v...

If enclosure size remains constant, say 3cuft each for the four sealed subs and 12cuft for the one ported sub, each of the sealed subs would require as much power as the single ported subwoofer. So...

You should be able to run full range pink noise from another source and use the RTA function in REW to measure the response.

I'd just pull the 4.0uF caps and check them out of the board, it's either those or the air core inductor solder joints.

We know the 2.2 ohm is good and the 8 ohm would not make a huge level...

The THX spec for reference level is for the speakers to be capable of 105dB at the listening position which is the number I am using when I say reference. So the HTM-12 should be capable of 105dB at...

HTM-6 and 8 are probably a little while out, don't even have prototypes for those yet.

As for the Fusion-15 vs. HTM-12, I can't really say much more. Fusion-15 has slight sensitivity and bass...

You can measure across the 2.2 ohm resistor and see if you get 2.2 ohms. The 8.2 won't measure right installed in the board because you will get the reading of the inductor that is wired in parallel...

With two 8 / 8.2 ohm resistors installed the high frequencies are 6dB hotter then everything below about 1.4khz. With the correct 2.2 ohm and 8/8.2 ohm the frequency response is pretty much flat. ...

The HTM-12 is voiced somewhat similar to the Fusion-15 but I think I may like the sound of the DNA-325 over the DNA-360 and in some ways the HTM-12 over the Fusion-15. I find the frequency response...

Of course if you want to try something new the HTM-12 should be available soon, and is voiced similar to the Fusion-15 but I think it might actually sound better.
