My amp has a switch from 4 to 6 ohm but reading more on the subject, I think I will just be happy with the 160 hooked up. I like to crank it up every once in awhile so I better not get too greedy.

My HVAC friend ordered the parts and sent me out to pick them up yesterday. I noticed the bottom part was bending the wrong way. According to the sheetmetal company, he ordered an offset, where he should of ordered a riser. I was forced to pay the $33 for the offset that I didn't need because it was a custom built part and I ordered the riser. I'll pick up the riser today.

Other than that, I'm just waiting for him to get a day off, so we can get this done.

If the offset was bent the wrong way what would a riser accomplish? I am confused. How about a pic of the wrong piece?

I can't do the pictures right now, nor today, but here's a description.

Duct coming up from room below. Looking at it from hole where speaker goes, you are looking at the wide side of it. It measures 8 x 14. You are looking at the 14 inch side. It needs to move farther away from you, then back up, to make more room for the speaker. Instead of moving away from you, the offset goes to the left (or right), then back up instead.

The Offset bends on the 8 inch side, leaving the 14 inch side flat.
The Riser bends on the 14 inch side, leaving the 8 inch side flat.

There will be a quiz next week to see if you can pass your HVAC class.

Makes sense to me.

The HVAC duct work has now been modified.

First picture is BEFORE modifications.

The next 2 pictures show the modifications. The top square corner contains 3 curved pieces to direct the air flow in a curved fashion.

Total cost, a little under $200.

did they say anything about a reduced amount of airflow due to the 90?

Very little to no reduced airflow. It's only 90 degrees on the outside. Inside, there are 3 curved pieces of metal to direct the air around the corner in a curved fashion. You can see the heads of the screws that hold this contraption in place in the bottom picture.

There are some minor leaks in the connections. I'm going to get a tube of silicon and seal these joints up good, as my next step.

Was the same thing i was thinking, reduced airflow, but if that unit was designed internally to be curved, then some engineer had his smart hat on that day.

In re: to the leaks, use aluminum duct tape. Silicon sealants fail over time.
