This has been a very interesting thread. I researched a lot on a sub to buy, ending up ordering the PSA XV15se. It should be here on Friday. I'm just getting into "true" subs, with my first being the Outlaw LFM-1 Plus I bought not long ago. I like the Outlaw and almost went with the EX for my other room, but in the end, couldn't resist the XV15se. Hoping it is as good as I've heard from others. It's pretty wild to see some guys on here with 4 of these.

I have the EX and it's a great sub, but you made the right choice I believe. The difference was pretty easy to notice in my 6k cu ft room. One thing that has always bothered me about the EX is that it's severely under ported in max extension mode (for my huge room at least), and max output mode extends only to the mid 20's or so. The EX in max extension mode sure does rock the small bedroom it currently resides in now though!

In my admittedly amateur opinion, the xv15se represents the best combination of the outlaw ex max extension and max output modes... Plus even more power and articulation across the entire range.

In other words, me thinks you won't be disappointed.

So, I moved last weekend and the new room with my audio stuff in it sounds SO much better than my old basement. I thought my XS30 was good before, but now I can actually feel it shaking the couches. I watched Need for Speed the other day and the sound was great. Story was meh, but really entertaining.

Now to possibly upgrade it with the new drivers...

I ordered a XV15SE and had it delivered to Hawaii (my parent's house). I placed the order late on July 30th, it shipped out the next day, and today we received the XV15SE (just one week later) in what appears to be in perfect condition. I haven't opened the box yet but it's without any dings or scratches. Awesome customer service and ordering experience. Thumbs up!!!

Hi Guys,

I've been reading this thread for a while now as I've got two XV15s, but this is my first time posting. I really enjoy the subs and recently got a MiniDSP to flatten the response and (I hope) make the sound even better. I know some of you have used a MiniDSP to EQ your subs, so I was hoping I could get some help doing the same.

I managed to get my response pretty flat using the MiniDSP and REW, but once I re-ran Audyssey XT32 (no SubEQ) everything got screwed up. I've attached a graph so you can see what I mean.

Should I have used the MiniDSP after running XT32? I thought I read that it's best to get the subs dialed in before running Audyssey, but I may be wrong about that.

Any other tips from those of you who have done this before would be much appreciated.

Thanks,
Josh

Quick question but did you have both mics in the exact spot and height?

Use the mini dsp post audyssey or audyssey will change the calibration to reflect what it thinks is best.

See here for a lengthy discussion on the "EQ before or after Audyssey" subject. I'm an "after Audyssey" kind of guy.

If you post your graphs with a 5db scale on the left side (instead of 10db), we will be better able to see what's going on. Otherwise, your graph settings look good (15-200hz, no smoothing).

Here is my two cents for what its worth. I think you are better served anlayzing a graph with your speakers playing. A large part of the eq process is the ability to tone down any large peaks, and smooth out the response in the crossover region with your main speakers. Above 50-60Hz or so, your response is going to look a lot different with your mains playing. This is the response you want to get as flat as possible after eq. I also agree that you should:

1) get your response as flat as possible prior to both audysey and the miniDSP. Do this by adjusting placement, phase, and even gain. I made big improvements in my FR by tweaking the gain on one of my subs a bit AFTER level matching them at the MLP. Got rid of a couple of dips and nulls. Adjust crossover as well in your AVR.

2) Run Audysey

3) Apply eq to your liking with miniDSP....house curves are helpful for lower level listening(i.e. -15 and lower)

Thanks so much for all of the help, guys. I really appreciate your feedback. I'll do the MiniDSP EQ after XT32 the next time around and see how that goes.

One other question: Audyssey sets the distance of one of my subs at 16.5 feet (sub 1) and the other at 9 feet (sub 2). To time align these, how should I set the receiver and MiniDSP delays? Should I set the receiver distance at 9 feet then add a delay to sub 1 so that the combined delay is 16.5 feet?

Thanks again for all the help.

you will need to run audyssey with the mini dsp in the signal chain, but do not use any eq till after the audyssey calibration is complete.

Josh,

If you have two subs, and your AVR will set individual distances for each you should be good to go.

If you ran Audyssey for each sub individually and those are the distances you came up with, then you will want to run Audyssey with both subs playing and then (after doing the sub distance tweak) add delay to the closer sub until you get the best response.

Following what other users have said, have mini dip in the signal chain when you run audy but do not use any filters. Once you have it audy calibrated, run REW and use that signal to generate a room eq that goes into dsp.

Are your xovers set to 60hz?

bh is right here, because the MiniDSP will inherently add a slight amount of delay when in the chain.

The crossover is set at 80 Hz and my receiver won't set independent distances for the subs, so I'll delay the nearfield sub using the MiniDSP after running Audyssey.

Thanks again for the help, this is all very helpful info.

Most of you guys using the USB Umiks? Or are some using the mics included with your system? Audyssey, McACC, YPAO for example?

From what I've read, the Audyssey-type mics aren't suitable for use with REW. I went with the UMM-6, but that was before the UMIK-1 was available.

I thought it was okay(like using a SPL meter) for lower volume FR checks...just not as accurate overall?

Also, we won't be shipping anything today(all sub orders last night and today will ship on Monday)...we're busy buttoning up a couple other projects..

What would be the main difference from the basic MiniDSP 2x4 and the Advanced 2-way? Obviously a noobie question, but looks like something new and exciting. I have three subs right now...

The MiniDSP 2x4 is the hardware, the Advanced 2-way plug-in is the software. You need both to be able to do anything with the DSP.

Guys I'm happy to report a very successful more than seamless integration of the XS15se into my 5.1 setup, it took about a week of moving my 120lb each mains and two subs around with in .5 of an inch ( I have major OCD ) to achieve the best combination of fidelity,finesse, agility and subterranean bass! The overall sound for both movies and music is breath taking, this is a testament of the quality bass the XS15se is capable of and I'm happy to report it has exceeded my expectation by miles. I'm not certain as to what the non SE version sounds like but this update ( close your ears Tom ) could've have easily warranted a justifiable price of well over a grand and I would have still considered it a screaming deal The method used to get the results where level matching the subs with XT32 + sub EQ the results are impressive on the ease of this for two different subs located in adjacent corners of the room, the results where as follows after Audyssey .

A gain setting on both well under 10 o'clock and post Audyssey level -9 db! ( I tend to favor a higher sub gain over pre/processor gain to avoid going over 0, besides any lower the subs would have been off )

A distance from MLP 16.5 for both subs

A confirmation via a DTS test disc showed Audyssey set them both down by 5db from the Raidioshack meters75db c- weighting, slow response! so I run them at -4db up 5 from the -9 setting.


As soon as the funds allow for the mic for measurements ( only as a I want to know why I'm hearing what i'm hearing cause I'm not touching a thing it sounds to good ) I'll post the results, as I've already did it the hard way moving it around with in inches in the the various locations available for placement and not to brag but its good to know I can still trust my ears.

Tom V. I know see why this seems to be the the sub you recommend most and while I'm sure you love all your children, I wont tell who I think your favorite just may be

Disclaimer the last part only applies to subs not kids

Gush over off to watch Dredd

The overall sound for both movies and music is breath taking, this is a testament of the quality bass the XS15se is capable of and I'm happy to report it has exceeded my expectation by miles. I'm not certain as to what the non SE version sounds like but this update ( close your ears Tom ) could've have easily warranted a justifiable price of well over a grand and I would have still considered it a screaming deal The method used to get the results where level matching the subs with XT32 + sub EQ the results are impressive on the ease of this for two different subs located in adjacent corners of the room, the results where as follows after Audyssey .

A gain setting on both well under 10 o'clock and post Audyssey level -9 db! ( I tend to favor a higher sub gain over pre/processor gain to avoid going over 0, besides any lower the subs would have been off )

A distance from MLP 16.5 for both subs

A confirmation via a DTS test disc showed Audyssey set them both down by 5db from the Raidioshack meters75db c- weighting, slow response! so I run them at -4db up 5 from the -9 setting.


As soon as the funds allow for the mic for measurements ( only as a I want to know why I'm hearing what i'm hearing cause I'm not touching a thing it sounds to good ) I'll post the results, as I've already did it the hard way moving it around with in inches in the the various locations available for placement and not to brag but its good to know I can still trust my ears.

Tom V. I know see why this seems to be the the sub you recommend most and while I'm sure you love all your children, I wont tell who I think your favorite just may be

Disclaimer the last part only applies to subs not kids

Gush over off to watch Dredd
Congrats on the new subs!

As far as Toms favorite goes, I suspect everyone that buys a sub from PSA feels like they got his favorite model. I think it's because his favorite model changes depending on the room and situation, but I could be wrong
