Yes, you can find and use a XO with High Pass and Low Pass Outputs if you want to adjust the Mains bass.
Step One: Find the natural "roll off" of your mains and "roll in" your sub at that frequency with as little overlap frequency as possibleStep Two: Place your sub so it is EXACTLY the same distance from your listening position as your mainsYes, you can find and use a XO with High Pass and Low Pass Outputs if you want to adjust the Mains bass.
A minidsp could also be used to achieve what you’re after. I have done it with pro analog crossovers too.
I've spent a lot of time integrating subs (too much!). There are lots of different ways to do it depending on what you're trying to achieve.I have found that hi-passing my bookshelf speakers does give them an additional level of clarity so I have done it that way. But that does make things a bit more challenging.One thing I can recommend is to use Room EQ Wizard to measure your speakers in-room response. Once you get the hang of REW the placement and integration of the sub becomes much more scientific, if not quite 100% repeatable.
thx John, looks I need to do some research on external XOs. And after seeing everyone put their sub in the corner of the room my entire adult life, it makes perfect sense to place it same distance from speakers for timing.
Thx. I'm assuming Room EQ Wizard is a type of DSP product?
...the will be at the sacrifice of POWER.
In your opinion, what's the best way to mitigate this? More subs (stacked)? Bigger subs?
It's measurement software that runs on Windows or Mac. The software is free but you'll need a calibrated mic to use it and those run around a hundred dollars.There are other measurement "solutions" out there as well but I've been satisfied with it. This link REW is an overview put together by Gik Acoustics.
The "corner loading" is often employed to take advantage of room boundary gains.However, it causes Phase Coherence Issues when the focus is on two channel music.Equidistant and time alignment of the subwoofer will reduce these phase issues BUT. . .the will be at the sacrifice of POWER.
john,good point about loss of power with only one sub at equal distance to speakers.however, the sub I am interested in, the Zu Undertone, is a beast and goes down to 14hz, and tight at low volumes. Honestly, even integrating a ONE sub in my listening room is kind of pushing it in terms of space and energy build up. So instead of opting for 2 subs that will offer balance but will be less quality than the Zu, I am choosing one solid sub to place in the middle b.w my floorstanders. The Zu sub "does it for me", and probably would do it for you too if you heard it, or its big bro the Submission. B/c you will SUBMIT to its bass. deep and powerful.I WILL need to employ some acoustic treatments, and I've used Roomtunes in the past, so i have a supply of them to try out once I get the sub and placed in room .
who?me?There are multiple free apps on either app store that you can use initially with your phone to get some idea where in the bass region your problem really is. Of course they are not as good as REW with a dedicated microphone but they will get you in the ballpark. In most rectangular shaped rooms it will fall in the 40-80 hz range but may actually be higher than your guesstimate. If you room is untreated and they are acceptable then much of your problem can be mitigated with corner bass traps before buying more gear. Adding only one sub to the room is not likely to help your situation where two might.
Thx Arthur. Gearing up to read about REW, I noticed there is an article that says you can integrate REW with minidsp device. Any recommendations for a room EQ mic?
