My cabinet has limited space. Is it ok to remove the XPA-1's feet, or will that cause it to overheat?

I probably would not recommend that. There are vents underneath and yes you could block the air intake. Also if you take off the feet you might damage any stand offs that stick out under the bottom pan of the chassis. If possible I would find another way.

What if I replace the feet with something shorter?

What if I replace the feet with something shorter? If you don’t have room for the feet does that mean there’s a shelf directly above the unit? If your cabinet is that tight you may have some overheating problems, you really need airflow all the way around. If it’s a G2 it probably even runs hotter than the G1. You could try it and measure with an IR thermometer, maybe post a pic. |

What if I replace the feet with something shorter? Shorter feet = less airflow. Either provide LOTS of space for ventilation or use a forced-air cooling system (fan). |

The cabinet is fully open in the back. I am planning to put another device above the amp but I need like .25 inches to fit.

The XPA-1 gen 1 is a high bias class A device with 10 watts of class A all the time. That produces significant heat. If you have the gen 2 and its in class A mode it produces high amounts of heat with 60 watts of class A. The venting on top is quite important for the amp. The XPA-1's are hot devices and I think it's a bad idea. |

An XPA-1 L runs at 35 watts class A which is also even more hot than the XPA-1 gen 1. Still bad idea imo for both of them. You can check with Keith @ Emotiva to be sure. |

If it’s too hot to touch you need more ventilation. These amps can run hot and be okay. However, blocking off bottom ventilation would not be a good idea

A question often asked (how much air space above an amp), so some time ago I tested (with a pyrometer) an XPA-2, XPA-3, XPA-5, XPA-100 and XPA-1L and they were all pretty much the same. Over 50 mm (that’s 2” in the old money) made little difference but progressively moving the shelf above closer than 50mm increased the temperature noticeably. That’s with a rack open on 3 sides, no fan.
Cheers

Cut one big hole or drill a lot of little ones, or cut slots.
My only problem with this is that just freeing up air flow isn't the entire issue. If components are stacked on a rack, and say the bottom component is A, with holes directly underneath, A heat makes B hotter, and A & B make C hotter, and so on.
I prefer having solid shelves with more space so the hot air leaving the component underneath is outside the component above.

My cabinet has limited space. Is it ok to remove the XPA-1's feet, or will that cause it to overheat? Without question, do NOT remove the feet. The XPA-1 is cooled by convection, based on the principle that hot air rises. If you block either the bottom or top vents, convection won't work. You'll kill that amp prematurely. |
