Power Sound Audio 2.1 System with MT-110 10" Speakers & 15V 15" Sub Review

This 2.1 system from Power Sound Audio does things that cost a lot of money, were you to try to get the same performance out of a pair of tower speakers. Yes, it's a bit industrial-looking but don't let that fool you. As long as you embrace bass management, DSP room correction, and the pairing of a good sub with competent satellite speakers, the the MT-110s and 15V combo is your kind of 2-channel system.

WRT PSA's specs, I've noticed they don't publish +/- db figures on their speakers. The MT-110 says 70hz-18hz, and you mention it's 10db down at 20khz, but is the 70hz figure where it ceases to be flat, is that 3db down, or something else? Did you have a chance to measure the F3 or F6 of the speaker on its own? I'm curious about how quickly it actually rolls off on the low end.

Looks to me like 70-18,000 Hz is akin to an anechoic +/- 3dB spec. Dirac says actual response (per the "before" measurements), at the MLP, is -3 dB at 75 Hz and 18,900 Hz respectively. I measured -5.5 dB at 70 Hz, but that could be impacted by the room. And treble was down only -1.2 dB at 18,000 hz, for what it's worth. But, after 18 kHz it really is a cliff. So says Dirac using a UMIK-1.

Very descriptive review,

To me, there is value with having a system that can put out more clean SPL than I can use (without hearing damage) no worries if I click around on the "songs with bass" links on the forum. No matter what chaos and mayhem shot through the system, just clean, smooth output without distortion, strain or compression issues showing up when in rockstar mode.

Disc Wars--great standard to stress the system! Make that sub and compression driver earn it's keep, glad the reference system worked out well for the review. You are right about using grills to hide the horns, I've surprised people when they pull my pretty magnetic grills off and have a horn loaded compression driver in their face. I guess if a speaker design looks like something found in a honky tonk bar, it has to sound like it? Odd how people think and make associations.. but fun to inform them this ain't no country bar...up next, Daft Punk.

Cheers!

PSA is top notch. Tom V is wonderful to work with. I have my entire system 7.1(dual subs).4 from him. (3)MTM 210, (8)MT110-SR and Dual T-18's. The clarity is stunning! It has been a year now and still going strong. I power the 7 channels with an outlaw 7900(300w per channel) and they haven't skipped a beat.

Mark, did you get the impression that your HT rig(with the Denon, right?) was able to push these well? 95db sensitivity tells me the amp would do fine, but my cognative dissonance kicks in when I see those beasts.

Yeah no problem in the HT rig, none at all, it's an easy speaker to drive and at worst someone might give up 2 dB by using an AVR instead of a dedicated amp. With the Denon I was probably leaving 1 dB on the table in stereo. The sub does the heavy lifting.

When you do frequency sweeps, are you using an RCA input on the receiver and hooking it up to a computer, or what?

Thanks for the review, by the way. I'm enjoying my 15V.

@imagic So no? Would be interesting to see the actual in room response and the single responses from sats and sub. The graph you've posted doesn't say what it is actually showing (sub and L or R or both)?

Not "no," but also not something I could get to right away. I'm busy as f*** these days.

True. That particular graph in the review is the L speaker, with the sub and an 80 Hz crossover. I'll label it as such, thx.

Here are the relevant FR screenshots from Dirac... I'll do the impulse charts later. I do want to include these in reviews so thanks for asking.

Thanks a lot. The sats drop like a stone below 80Hz. Did you do any near field measurements to see whether this is the room or the speakers themselves?
In any case a 80Hz crossover is way too low. Sub and sats should overlap by about 1 octave so a crossover point around 160Hz is probably better.
Your room shows a lot of variance around 70Hz. Maybe a different location for listener and/or sub would have worked better?

160 Hz would be untenable to me as far as localization goes, but I understand your point there.

My setup is a compromise in placement, for the sake of livability. If it's my own system, multiple subs go wherever. But, sub in front corner and speakers a few feet out from the wall is so common, I am not searching for something more optimal although I am sure effort would reveal better specific positions.

I am tolerant of compromises in terms of the room and placement and all that. It's interesting to see how different speakers interact with the room.

And I do think that there is a no that is exacerbating the roll off in response. I am ambivalent as long as Dirac finds a workable solution.

That's why it would be worth to do a near field measurement. The inflexibility of most AVRs regarding crossover don't work with a speaker that falls off so early.

When I put them in the surround system, Audyssey chose an 80 Hz crossover on its own, fwiw. So, it did not set off alarm bells. My bad for not doing a nearfield measurement, even if I did not post it. The speakers and sub have already been returned, so I can't perform any more measurements.

Looping back to an earlier comment of yours, if I can use RTA to make workable adjustments to the MLP or speaker positions, I will.

Thanks for the review; PSA seems to be everything it is advertised to be by the company and enthusiastic AVS members who own them.

Interesting that at normal listening levels the PSAs can be matched by more pedestrian gear; no way can I sustain much above 90db at 15 feet...plus I have neighbors.

Also interesting that the Denon performed in a rather transparent fashion just as the the more expensive amplification did.

If I had a large well sealed HT room no question these would be a great choice.

But, sadly, living in the Bay Area "big" is an 18x15 room!

do you mean that you made a custom curve of 24 dB in Dirac????? If yes, can you share your Sub Target File contents?

If you want to properly understand frequency response in the rom mode dominated region with in room measurements you need to do proper measurements, not just measure the speaker a few ft away with the DL software.

The sub 100Hz response could be purely modal interaction related,

It's not really worth posting nearfield measurements if they aren't taken properly. I'd love for AVS and other magazines to properly review speakers like Stereophile or Soundstage does. See here: http://www.stereophile.com/features/...GXvF5kEF5Qi.97

Not sure which way you have your mic facing but 1/2" capsule measurement mics become directional pretty low in frequency, and especially above 8kHz.

It's also not worthless and for sure better than nothing.

That's exactly why I asked Mark if he had done a near field measurement (as per Keele) at the sat's woofer

I second that. Especially when the S in AVS stands for "science" and not just for another word that also starts with an S...

I used the BM plugin on the DDRC-88A which offers miniDSP-style bass management. That occurs just before Dirac processing. You do get to choose the slope.

That's exactly why I asked Mark if he had done a near field measurement (as per Keele) at the sat's woofer

I second that. Especially when the S in AVS stands for "science" and not just for another word that also starts with an S...
As I always say, my PayPal account is available for anyone who wants to start sending me money so I can build a dedicated speaker review lab. Go for it, you can be the first to donate to the cause!

Beyond that, I'd appreciate it if you guys would pay for an assistant. That would be great. But you'd have to pledge a weekly donation for a year for me to even consider hiring one.

Oh, and can you also provide some funds to hire someone else to go report on news and manage the homepage and...

Anyhow, maybe I do nearfield and maybe I don't. Maybe I post it and maybe I don't. I'm not gonna become Stereophile tomorrow. Plus, y'all must just be referring to the measurements part of that magazine's reviews because the written part of Stereophile reviews ain't science. How many times is that magazine gonna say a speaker cable does this or that to how music sounds? And if they believe the cables (including USB cables and power cords) produce audible differences then what does it say about their comments regarding speakers? Have you read reviews where they declare "no measurable difference but it sounds much better" Yeah, science.

- "You can see from the "Measurements" sidebar that I could find no significant effect that the JitterBug had on the analog signals output by three of the DACs I had to hand. Yet with those DACs and others, I heard an improvement in sound quality that I can attribute only to the JitterBug. I hate when that happens!" - John Atkinson

Thanks for the comments!

Oh yeah BTW AV Science is another company. We are AVS Forum. Not to play semantic games, but the AV Science folks really do own that name https://avscience.com/. And really, are you gonna convince me that all that bickering people do over stuff nobody else cares about is "science" haha no it's people using the Internet as a therapist.

Anyhow, most people don't care about the minutia and that includes picking apart nearfield measurements that are, indeed, troublesome to get right. Heck, avoiding errors 3 dB and larger in an anechoic chamber is tough and requires rigorous measurements. I'm not going down that rabbit hole in my living room.

Now, if the majority of readers were like you guys and all paying extra so I can run a review lab, that's the sort of review I'd write.

As it stands, I'm looking for ways to make reviews shorter, not longer. https://avscience.com/

Facing up. It's a UMIK-1. Other speakers measure past 20 kHz using the same technique.

Oh I think I do understand the economics behind journalism these days. But there is a difference between reviewing a product in the service of the customer and in the service of the advertiser/manufacturer. The latter pays your bills the former is the right thing to do.
