Dual subs for hi-fi 2ch music

[usery]

With a 10 ms max delay, I don't think that wireless connection will hurt the sound quality in the subwoofer's range at all.

If no compromise in performance and fidelity that might be something I'd consider. Would have to be bullet-proof however - I'll be down in the crawlspace anyway, running Straight Wire Pro-12 Special to the Boxer monitors. Running another set of cables while I'm down there is not a big deal.

Know anyone running this wireless setup to sub/s?

I would recommend one or two of [SVS SB-13 Ultra]

Ouch - would love to but budget won't allow. Are there alternatives for a pair of high Qts subs for <= $1500 that would fit this evolving rig well? Or is that dope-smoking?

Option 3 and 4 require the purchase of an electronic crossover and this should do the trick.

thanks, will study/research to figure out how to integrate.

Option 4 is to use two subs. You would then need a 30 ft. balanced cable for each sub.

Yes am inclining towards 2 subs if can make suitable hi-Qts units work within budget. Any specific balanced cables to recommend?

If you place the speakers on the subs, you will need to find an elegant way to elevate each sub. The alternative is to place the subs along side each speaker.

I'd prefer to place along side and not stack. I do have an extra pair of heavy stands, sand/shot fillable, with 18" base plate height. That would put center axis of a 15"-18" sub enclosure close to 26" base plate height of the Boxer stands. Think that would integrate reasonably well?

Thanks again for all the guidance, much appreciated.

What makes you think it will degrade the signal?

Well it won't be handling just the sub if he uses RCA cables. It will be a full range signal to the sub and he will need another device to send the high pass signal back to the amp. This is a no go solution for him.

I think it would integrate well.

The point to remember is that one good sub is better than two poor ones. I would use one sub centrally placed and used the summed LFE output of the Behringer to drive it via balanced XLR cable.

If you want a little improvement you can add another sub as funds allow. One of those subs plus the crossover will put you a little over budget, but it will be well worth it.

My suggestion was based on utilizing the crossover you suggested. There would be no need to return the HP back to the mains.

Then his best bet is a balanced cable.

Thanks, given that guidance and all my other constraints I'm looking at a single HSU ULS-15. Behringer to ULS-15 connection is straightforward: balanced XLR from Behringer sub out to ULS-15 XLR in.

It's the Creek->Behringer->Creek connections I'm struggling with. If I'm looking at this right, I need two RCA (L + R) males to a single XLR male, in a single unbalanced cable. If that's correct then I'm having hella time finding that cable (Amazon, BHPhotoVideo etc). Here's my understanding of how to engineer this:

a. On Creek int amp remove factory RCA L/R jumpers from preamp-out to power amp-in circuit
b. Connect Creek L/R preamp-out to CX2310 XLR-in via RCA-to-XLR cable (unbalanced mode - XLR pins 1 & 3 jumped in cable?)
c. Connect CX2310 High freq. output to Creek L/R power amp-in via XLR-to-RCA cable (also unbalanced)
d. Connect CX2310 sub out to either of the 2 HSU ULS-15 XLR ins, via single balanced XLR cable (per ULS-15 user manual)
e. Connect Creek to mains with Straight Wire Pro-12 speaker cable
f. Configure CX2310 high pass for the mains. ## anything else I need to config on CX2310? e.g. lo pass for sub-out?

Does this look right? Any suggestions welcomed.

These will make it easy for you!

Connect the pre outs of the Creek to the inputs on the Behringer. Now connect the high pass outs of the Behringer to the amp ins of the Creek. Now run and XLR cable from the summed low pass out (LFE) of the Behringer, to the left in XLR of the HSU.

Then play with the crossover point for optimal results.

One thing I should add. Set the crossover on the HSU as high as possible. Use the Behringer to set the crossover. That way you won't stack crossovers.

Great, thanks again, nearly there. This:

You mean run XLR from output #2 instead of #6, with Behringer in stereo 2-way mode?

I would use the subwoofer out which is 6. So the preouts go to the inputs and the high out to the amp input and the subwoofer out to the sub, left input. That way you will need only one cable. If you use the low outs you will need two cables.

Again, hi-fi music repro across above genres is sole purpose of this rig. Especially important is ease & flexibility of inline integration of the subs with it. Suggestions/feedback greatly appreciated.

Perhaps a little late here - over the years in a 27’x28’space and several systems later - I’ve employed dual subs/stereo subs from two of the most popular sub makers in these forums in a dedicated 2 channel acoustic treated space - the subs single or dual performed rather well - but not the last word in refinement to music - this is not the subs fault - but rather the design implementation to the mains - in order to best integrate the mains the sub should have an external xover between pre/amp - high pass filter/low pass filter with a low 'Q' factor IMO - we are talking music only here ... right? - I’ll stop here before I get booted out at the end of the sub journey for music I settled on a single sub - music ranges from techno to classical.

Yes music only. There will be external xover between pre and amp (Behringer CX2310) with high/low pass tuned accordingly. I'm starting with a single sub (HSU ULS-15).

My music range is same as yours: intelligent dance/techno to classical opera/orchestral/chamber and everything in between. If you aren't already listening to The Field, you should be ; )

Thanks for the tip - will investigate - the image posted didn’tmake it I see - will try again.

Very nice system and room, you definitely need a subwoofer with them guys...

yes awesome setup & great looking room.

does room screen/divider at right channel serve any acoustic purpose? I need to do same at my left channel/main to provide some reflecting surface, otherwise the area opens into high vaulted ceiling DR of 1430 cu. ft.

 

[vinyl]

Screen is for aesthetics and hides all wires - it may well contribute minimally - the main acoustic panels/diffusers are on the frontwall. <o></o>

 

[ImcLoud]

We need more pictures of this system, some close ups and equipment lists may help to satisfy our hunger....

 

[vinyl]

Perhaps this size will work.

Amps are Crown K1’s - Maggie 1.6 on Anchor Stands - sub is Vandersteen 2wq - the little Jolida used with Thorens TT for an all analog playback - digital playback via Parasound duo D/AC Ultra 2000/C/BD 2000 BeltDrive Transport - there are other pieces but irrelevant in overall scheme - bottomline at days end IMO - boils down to the basic requirements: speakers > room> room acoustics > decent equipment > and of course a great recording - any other fluff is simply that.

What you need is subs that don't sound like subs. The comment I get on my subs is "These don't sound like subs they sound so real". Make any sense or what??

You mean subs that sound like tight bass from high-end tower speakers, but more intensity?

I can speak for the RBH SX-1010 (probably also SX-1212). The SX-1010 was made to be the bass portion of their flagship towers. So they are literally tight bass from high-end towers.

I remember when I first heard the RBH T2 towers. I was floored by the sound of the bass. I mean the midrange and treble were great, but the bass was just so crazy tight and punchy I couldn't believe it. So just had to have it.

Of course, I think other great subs (like Funk & Rythmik) are also awesome.

The key to great "tight tower-like bass" is to have great subs and great Sub EQ. You need both. I use Audyssey Dynamic EQ on my Denon. Works great. Love it. Can't live without it.

That's exactly what I am talking about. No rumble just tight chest pounding bass.
