Feedback on Hypex UcD700 build for midbass?

[LewinskiH01]

Hello.

I'm building high-end active 4-way speakers and I'm looking into my midbass amps (80 to 500Hz). This will be my first amp build, so input will be appreciated!

They will be monoblocks located either very close (1m) from the speaker or attached to the speaker back/bottom, driving each a pair of Beyma 10G40 connected in parallel. Building around UcD700 to get clean 500W with THD under 0.06%. Hypex Tech service suggested it was not worth getting the version with HxR regulators since it was to be used for 80-500Hz.



This is what I would buy from Hypex:

• UcD700HG and UcD signal cable
• SMPS1200A700 power supply, and corresponding cable set
• Softstart module
• Push-button with led

I also need a case, chassis female IEC connector, XLR connector, speaker binding posts. Is it worth buying hi-end parts here, considering the frequency range these will play at, or should I just go with the parts available at Hypex webshop?

• IEC connector: Hypex @ Euro 2.9, Furutech FI-10R @ US$ 35
• XLR connector: Hypex @ Euro 4.9, Furutech FP-682F @ US$ 69
• Speaker binding posts: Hypex @ Euro 12.5, Eichmann CablePods @ US$ 129
• Subtotal: Hypex @ Euro 40 vs hi-end @ US$466

In the big scheme of things Euro 40 vs U$466 is not that much money when you consider the total amount I will spend on speakers and amps. At the same time I don't enjoy wasting money just for fun! What would you do?


Anything I'm missing here?

Thanks!

a nu1000 cost 150$ , two 1000watt alread built. If your not plugging and unplugging the wires constantly the normal connectors will do. A little resistance in signal can't touch a 700 watt amplifier.

Yes, those nu1000 are cheap and powerfull. But would rather go with monoblocks.

After I'm done with the design phase it will be a "plug and leave it alone" operation. So you are saying it wouldn't be worth sonically to use upgraded parts. Got you. Thanks.

Any other feedback?

'So you are saying it wouldn't be worth sonically to use upgraded parts'

It doesn't do anything else beside shining. Those Hypex are used in 3k$ amplifiers.

What you want is highest frequency possible and drive them hard (100db + ) as the performance is way better at high power this from the university thesis I read on class D amps on the bench testing equipment.
