We are proudly announced that the large RE4821H was finally released! It's the best choice for those power enthusiast who is looking for a real high-end enclosures for their class A amplifier.

This case are all made of aluminum. It has the size of 480x210x376mm. The size of the heatsink is 300x200x50mm. It's ideal for 50Wx2 stereo class A or 100W mono block. As we promised the price is the most competitive in the market: only $260 for this monster!

The front panel and back panel are blank now. If you think it's better to have some cutouts (such as IEC connector) please let me know.

Hi Ray, I am in Shenzen from June 16th to 19th. Do you have a store there where I can pick up as mentioned. I am interested in this case. Thanks, John

JohnG,
are you passing Scotland on the way home?

JohnGeneva · 23rd May 2012, 06:10 PM

Sorry Andrew, wish I was. Baggage is problematic as is but I see ray has put surface shipping at 45 dollars on his large enclosure at 13 kilos. this looks like a good deal costwise.

Lovely looking chassis. We are a group of DIY enthusiasts trying to build Pass DIY F5 Turbo dual mono amp. You can read about it on this thread on the India-specific hifi forum: DIY: Pass F5 turbo v2 initiated

Is there a way of shipping them to India? Wonder how much would the shipping be?

I had already read your thread before, it's a nice design.
Sure we can ship it tho Indian. Shipping cost to Indian is much higher than ship to USA or Eruope. Sea shipping takes less than $80, but will take very long time. Air shipping will takes at least $180
