Hypex UCD modules come in either 180, 250, 400, or 700 watts @ 4 ohms.
Then there is a mega 2000 watt module

Filterless so the 10hz.Did you order it with the 10Hz cutoff or the 45Hz std?
Yep that’s mine! He is milling out the RCA area a bit to allow me to use my thicker Esoteric Audio RCA’sThat's probably the one I saw on Tuesday! They were making a new input shroud to clear your RCAs, right? If so, great choice of RCA, those are my FAVORITE!
What exactly does this mean? I know you're not saying they violate ohms law, but please explain in layman's terms.Their load invariance allows them to be agnostic to impedance curves which are especially extreme with subwoofers and ribbons tweeters. The sound is amazing
It does when you need to understand what it can physically do to your car. Example: 4 horsepower subwoofer system flexing parts of your car that really shouldn't flex.I cannot imagine "needing" 360W... that is ~1\2 horsepower per channel.
Assumng it makes sense to rate power in HP.
But I thought these were being used for the upper frequency speaker channels?It does when you need to understand what it can physically do to your car. Example: 4 horsepower subwoofer system flexing parts of your car that really shouldn't flex.
I'm speaking in general terms, rating in horsepower for subwoofer systems would help understand the physical effects on your car, I don't think it would be at all useful in understanding higher frequency systems.But I thought these were being used for the upper frequency speaker channels?
I could see it for a woofer, but not a MR or tweeter.
I agree that HP is nonsensical, which was the intent...I'm speaking in general terms, rating in horsepower for subwoofer systems would help understand the physical effects on your car, I don't think it would be at all useful in understanding higher frequency systems.
There are several different class D techs out there..What exactly does this mean? I know you're not saying they violate ohms law, but please explain in layman's terms.
That is a better reason than needing 300+ watts.Also can’t forget what I can’t keep saying enough of...
made in the USA with a lifetime warranty!
Thanks, exactly the info I needed to understand the frequency agnostic statement.There are several different class D techs out there..
but Hypex UcD is the only one able to claim low, flat THD response, invariant of frequency and load. This allows for very linear power with a frequency response that is entirely load invariant.
There is sometimes a lift in the top octaves added by poor class-D topology creating an unwanted “too cold” sound. Hypex has ‘solved’ this with UcD, their amplifier topology remains linear through the entire range regardless of load impedance. It is just "neutral" what goes in is what comes out, clear and clean.
If you really want to dive in check out the Hypex white paper:
The secret sauce is in the patented post-filter feedback design.
About 2 weeks. But most of that was my doing. Instead of the yellow color that is standard by the connector plate, I requested a plain black plate. Slight delay in when he was sending out new plates out to be anodized to fulfill this request.NICE!
I think I need one or two of these in my life! What was the turnaround time for this?
No doubts about it. The linear power and clarity my BT4180 provided was already unreal to grasp. My build is a slow progress project and still have some work to do in my sedan trunk for a stealth false floor setup but I hope to have this amp singing before Thanksgiving.That is awesome! And funny since it will do more like 1200-1600wrms at 2ohms, very underrated. Can’t wait to hear how you like it.
These things are of solid build quality. Once you hold it in your hand and feel its mini heft you’ll understand. As you mentioned these amps are were physically designed to fit in bike fairings or saddle bags where they would experience long periods of exposure to heat/sun. I think they should do fine given their 90% efficiency. Plus they have active cooling via 2 internal fans.Thanks for the detailed info and pics!
And yeah, I love those EA E7 RCA's as well.
For the system I'm currently working on, I would probably need one of the BT4250 and one or two of the BT4180 as well.
I guess these are made to be placed inside a fairing or in enclosed saddlebags on a HD, but do you think they'd have any problems heatwise buried under the rear quarter trim panel or in the sealed front boot of a 911 Porsche?
Would love to have these included in the next high-end "SQ Amplifier Shootout".
