Subwoofer suggestions for budget system?


My current setup is a pair of Magnepan 1.6 speakers, a pair of Schiit Vidars, Schiit Sol turntable w/Goldring E3 cartridge (I have a VAS-rebuilt Denon DL-103 with Ebony shell and microridge stylus when I can get someone to come set it up for me), Mani 2 phono stage, Asgard 3 headphone amp acting as preamp, Schiit SYS as source selector, Modi 3+ connected to Volumio for streaming digital and an Orchard Audio RCA-to-XLR converter to drive the Vidars in monoblock mode.

I'd like to add a subwoofer to the mix that can keep bass out of the Maggies.  I'd, of course, prefer a dipole sub to go with the dipole speakers, but not terribly picky ATM.  My budget is around $200 to $300 for now.  I have been very tempted to build a pair of my own subs, but that's not in my budget right now.

Suggestions?

@grislybutter When you say “terrible,” what specifically do you mean? It’s possible you’ve got the volume and/or crossover set too high and/or placed in a bad spot. Here’s a quick n easy guide to help at least get the sub’s settings properly dialed in.

But before doing that I’d do the “sub crawl” method so you can to identify optimal placement areas for the sub in your room. Basically you place the sub on the listening chair where you’ll do your listening, put on a bass-heavy track, and then crawl around your room (so your ears are at the same level as the sub) and identify the place(s) where the bass sounds best (tightest,well-integrated/balanced, tuneful) and mark them with tape. Choose the spot that works best for you in the room and then calibrate the sub’s settings as per the instructions in the above link. If you do this and the sub still doesn’t sound good I’d be concerned there may be something wrong going on with the sub. Last, SVS has excellent customer support and I wouldn’t hesitate to call them if all else fails. Hope this helps — now, on your knees boy!

That location seems questionable to me. Did you map your rooms modes and nulls using the crawl test with the sub playing tones at the listening position? 

Contacting SVS may provide some improvement.

thanks! I started the crawl and I found it to be best between the standmount speakers, by the back wall. I don't think anything is wrong with the sub. I tried a longer cable to move it to the sidewall and it was very muted. My better RCA cables are 6 feet and I am wary of using barrel connectors. On the "plus" side, my CFO told me not to get attached to it, I only got approval for trying it out and returning it :)
I am browsing used ads, I think a smaller, older unit could get the job done.
