So, not much difference from the stuff in the 80's, then...

😉

 

Nakamichi car audio in the 80s/90s was absolutely top of the line.

My cousin had a BMW in the late 80's with a custom Nakamichi system from Earmark that cost something ridiculous like $15k out the door.

You can score an unopened TD-9 deck on eBay for only $1500

For audio quality, yes. But for reliability? Not in our experience.

I think I have the receiver option figured out after a ton of reading. At least the "how" part.

lr-layout.thumb.png.0eb1d3164bbe25f9e5ff951091df2eae.png

 

Since we're on a new page, here's the layout diagram for reference.

Behind the cabinet I would add a wall plate with banana jacks. I would drill 1 or 2 holes through the bottom 2x4 into the joist space. Then I'll add similar plates (less connections) behind the couch on the left, and back/right corner behind the primary couch.

The runs themselves would be from the receiver to the plate, then from the plate down, to the left about 10ft to where I have joist access in the basement. Then 15ft towards the bottom, along the joist to the bottom right corner area where I already have a defunct phone drop with a blank plate over it already. That would allow for 2 back speakers and one right surround.

The run to the plate behind the left couch would be about half that run.

Later on if I want to add more, I can run additional cables to additional jacks.

 

Now, I've figured the longest run (plate to plate distance only) to be about 43ft. Add another 10ft onto that for total longest run (back left speaker), and that's a hefty bit of ground to go what would be 1/4 that distance direct.

With that being the case, I'll be using 14/4 CL-3 wire for those runs, and twisting the 2 pairs together. Same amount of cable in terms of total feet, but the wire is a little less than 12/2, and wiring together should yield a lower resistance than a 12/2 on its own.

 

The other option would be to find some type of raceway, or 3/4" conduit. With them adding another 3/4" of sub-floor on top of the existing sub-floor (for height matching, and leveling), I could run the conduit first, and let them add the sub-floor around that. Wouldn't make a ton of sense for the run behind the couch, but would work for the longer runs. Then again, that may piss off the installers with now having to make cuts for that. Guess I could always use a router to make out a groove for a track, once the sub-floor is down to help them out with that. A little leveling compound across the top to even out any gaps around the track and work out any height issue.

Second option would make for shorter runs, but may be more hassle than it's worth.

 

Of course I still have to decide between doing that and just throwing a soundbar setup at it. The replacement lot of flooring shows up next week on Tuesday, and install wouldn't start until at least next week Thursday. Since I haven't been contacted yet for the install date, it most likely will be later. So a week to 10 days at least to get it settled. If not, then it would be under and around with longer runs if I ended up going that route.

Looking into upgraded the home system for music and movies. Just bought a new center speaker. Throw out suggestions for a sub-woofer. Also throw out some suggestions for the other speakers in a 9.5 setup. The JBL's are not going to be replaced, much to the dismay of my wife. 

 

Yamaha RX-V2085 receiver

2 Pioneer SP-BS22-LR Atmos side speakers

Cheap Onkyo surround

Klipsch Reference Premiere RP-504C 600W 2.5-Way Center Channel Speaker, Piano Black center speaker

30 year old JBL L7 front speakers

Room is 12' by 18'

I just put in an SVS setup. They’re pretty fucking great.

Prime PB-2000 would be a great sub for that size room, Their bookshelf for surrounds, and they have atmos sides as well. Their true 3-way center is tits, too. 

would 2 subwoofers be over kill?

My room is about the same size as yours, and 1 is fine. Depends on the acoustics of your room, but in terms of size you’re ok with 1.

If you want 2, ok. Won’t hurt anything, but could easily be overkill.

If SVS is interesting, crutchfield has some bundled packages that will knock some off, if one fits your needs.

Curious, how do you connect 2? Both go the receiver or does the second daisy chain off of the first subwoofer?

Having two subs is not about decibels necessarily, it’s more about even distribution throughout the room. I think the stat is about +3db for 2 vs 1 when properly tuned. Also get a big boost in tactile bass. 
 

An AVR with dual sub inputs makes the process easy, not sure how to do two without dual inputs other than to split the line from the AVR and tune them individually as best you can?

One trick for locating your subwoofer:  put it in your listening position near ear height, play some music or other content with a lot of deep bass, and then walk (well, crawl) around the room to find the spot that sounds "best" (most likely, the deepest and loudest bass).  When you find that spot, put the sub there.  It's a reciprocal setup.  Then, tweak the subwoofer volume so that it sounds best to you.

Amazon basics has some cheap long sub cables to make the sub crawl easier
