Help with Vintage McIntosh amp connection to SVS SB-1000 Pro subs

[Deleted member 43957]

My last foray into putting subs into my room was frustrating and I sold the subs to "stop the madness"... lol. Well... I guess that I'm letting some of that soften with time, in addition to a good deal on a pair of SVS SB 1000 Pro subs, has me looking to the best place that I know to get facts, that's you guys.

I've got a 1990's era McIntosh MC7300 amp with its "signature" connectors (which I find to be a general pain in the a$$). The mains are Revel F206's. I don't intend to have any bass management, other than the SVS App, which looks very capable (and which I'll look for advice here, once up and running).

1. How do I best run the cables from the amp to both subs? It's easy enough to have a banana clip adapter for the amp with stacking plugs if need be, as shown below.
2. Suggested xover app settings considering the mains?
3. I hope my fancy cables don't offend

I'm attempting to take the path of least resistance with this setup, which means to keep it as simple as possible, while filling in the bass that the 206's don't. Given that mission statement, any thoughts? Thanks.

Screw terminal to banana adapters perhaps?

I've got those, thanks. My question is what amp terminal is connected to which sub terminal, assuming that that either at the amp, or the sub, or both, their needs to be a stacked connection. Is that the answer, that I'm using the same connector on the amp for the subs, as the mains? Is it that simple? That means that the same connections shown in the pic for the mains, are repeated for the subs and connected to the sub's speaker level inputs R/L?

Thanks?

I'd ask SVS. Their customer service is usually very good.

No pre-amp outs available? What is the source for the amp?

Remove the caps from the SW terminals?

what he said.

Yup, pre amps out to Node (N130)

 

[RickS]

So why not the N130’s sub out?

 

[babadono]

split the signal at "audio out" line level and run to both the MAC and the first sub. Looks like the first sub then has line out to your second sub.

or this

Because I was stuck in my box thinking of how to fail... lol. Should I split the Node's sub out to both subs and not run anything from the amp to the subs?

Yes, you could do that. Probably your cleanest option by far.

 

[babadono]

and this is just me and I'm anal about stuff like this ...I would put some ferrules on those speaker wires at the MAC and use those screw down terminal blocks as intended.

Good suggestion. How are the screw down terminal blocks intended? I thought that there had to be a better way than what I've done here. I've got the banana plug adapters, I'm guessing that I should use them?

Yes, you could do that. Probably your cleanest option by far.

Then run it directly from the sub out, split to L/R Input on each sub? That makes perfect sense. Thanks. Just to combat additional ignorance, @babadono solution wasn't on my radar either, is this an equally viable solution, straight run from Node to sub R then out to the sub L input? Any suggestions regarding setting the xover with the 206's?

See this for starters…

Subwoofer - Line level or Speaker Level

My subwoofers havr both speaker level and line level (rca) inputs and outputs. Would it be better to connect them between my DX7s and my amplifier with rca cables or between my amplifier and my speakers with speaker cables?

What crossover options does the Node have?

That was a good suggestion. I did. Here's what I asked:

Q: My question is what amp terminal is connected to which sub terminal? Should I use the same connector on the amp for the subs, as the mains? Which means that the same connections shown in the pic below for the mains, are repeated for the subs and connected to the sub's speaker level inputs R/L?

A: Yes, that is how I would wire up the subwoofer.

Given the ease of splitting out from the amp, the SVS solution, the one that I offered them, seems messy and unnecessary. Is that a reasonable conclusion? Of these 3 options, the splitter seems cleanest.

Thanks for that link. That answered the underlying question and supplied the sleekest solution. Amir called what I thought was the case a myth... which is what I suspected and why I wanted some clarity, and I'm getting it... glad I overcame asking a stupid question... lol.

This is the only xover option on the Node 130, I believe. The SVS has bluetooth and an app and assuming that it has more options. Are there any settings that you'd anticipate that should be set from default to start out?

80 Hz is usually a good start. Do you have a mic to do room measurements?

Btw, depending on subwoofer locations, daisy chaining would eliminate need for splitter.
