Starting another H/T

[95Honda 486]

Finally getting around to designing a H/T for our new house. Substage will be a McCauley 6174 in a 12ft3 4th order vented at around 18Hz powered by an Adcom GFA 555. I picked a clean Sony ES on Facebook Marketplace for almost nothing. Front L/R and rears are Paradigm in walls, their reference series, should be pretty good. For the center channel I designed a large line array with 2 sets of 5 drivers in Bessel arrangements flaking a Peerless 1 1/8” dome. Hopefully I’ll have some build pics in the next few weeks. I am really looking forward to the sub stage. I have used the 6174 in many pro audio builds before, but not in a small H/T.

Center Channel coming along

Subwoofer almost done. It ended up being pretty big. Internal volume is 13 ft3 tuned at 18Hz.

The Adcom sub amplifier

Whoa!  That's a big subwoofer!  Whats the deal with McCauly?  I just looked up their site, and they look to have some products, but not a ton.

They are a pro audio company that has been around for decades. The 6174 was one of the first true pro audio subwoofers. Once the Aura Sound NRT came on the scene, it sort of dethroned the 6174, but more in sheer output. I don't know of too many other drivers available to this day that are as efficiency as a 6174 on the last octave, if enclosure size isn't a concern.

More pictures of everything done. The center channel sits right below the TV.
