Using PA Speakers In A Home "Audiophile" Application!


Hi guys,

I am a bit inspired to explore/trial usage of a pair of PA speakers at home after i attended a live event recently. 

I looked at some Yamaha PA models and zoomed in on one that isn't too huge/heavy, relatively easy to move around perhaps. 

Are there any audiophiles here who had relative satisfaction trying such speakers at home? I am also thinking that this may not be a great idea, but, just curious at the moment.

In my humble opinion, one doesn’t necessarily have to exclude the other. PA speakers have many good offerings for domestic use - some options have already been mentioned.

More to the point though, much if not most of the bias against PA/pro speakers for home use comes from prejudice and "listening" with the eyes. If there’s any real experience to speak of it’s from concerts blasting away with serious SPL’s and gear closer to its limits than not, and how’s that an indication for use in a home setting? Try hanging up a bunch of Wilson’s or other hifi speakers in large clusters, just for sports, and have them perform at concerts at the end of their ropes. There’d be mostly smoke, I might add, other than the fact it wouldn’t sound anything like it would at home. Alright, as an outset either segment of speakers are built for their specific purpose, but one of them will do better in both scenarios, and it isn’t the hifi speakers.

Seriously, how many audiophiles have tried speakers from the pro segment in the home setups, and who even cares to? Ramble on this, ramble on that. Moreover, PA is just one segment of the pro sector; there are pro cinema speakers as well, that is to say large high efficiency speakers that can take loads of power, and they’re often better suited for home audio reproduction.

I’m not claiming hifi and pro segment speakers sound the same in a home setting, but where they differ it’s no necessarily at a disadvantage for pro speakers. For starters, blanket statements about how pro speakers can’t sound refined, is bollocks. Claims about their lack of imaging capabilities aren’t well founded either, I find. That being said it’s important to know all pro segment speakers aren’t the same, and while some of them may be less suited for home environments from a refinement and imaging point-of-view, others are downright great.

For those who have gone to great lengths finding and optimizing their particular hifi speakers in their homes, well-implemented pro segment speakers mayn’t be their cup of tea, certainly not at first (and once preconceptions may have worn off). I’m not saying that implying all such people would find pro speakers to sound bad by comparison, but merely that there would be differences in the presentation that might trigger them into believing that initially. Preferences and all, and not least habitual exposition.

Bear in mind that one can optimize pro speakers in one’s home as well; it’s not exclusive to hifi speakers. And whereas most hifi speakers are passively configured, many pro speakers are configured actively, outboardly as well, and the latter in particular offers some distinct advantages over passive speakers optimizing them into their specific acoustic environment even more thoroughly.

Why would pro speakers sound different to hifi dittos? Look at the physics and design of things, and then compare them to the segment of hifi speakers that are high efficiency and capable of fairly high power handling as well. As such some hifi speakers could also be labeled pro-ish segment, but they’re just neatly wrapped in veneers or lacquer, not to mention oftentimes being very expensive. By comparison pro speakers intended for the pro sector are typically larger and more rugged looking, but more importantly they’re designed to actually meet a design goal and application from a basis of raw functionality, whereas hifi iterations of this segment of speakers are typically compromised by size limitations to cater to domestic demands, with all that entails as to their functionality.

The question could be raised whether the design goals for a pro application make sense for use in a home setting, but to me the most important takeaway is whether there are any obvious impediments to stand in the way for proper integration here. Designing a product more strictly from the basis of functionality to me is both meaningful and beneficial in a home setting, not to mention honest and "what you see is what you get." Lastly and not least: if it sounds great, it sounds great - irrespective of whatever the hell. 

I don't know about these particular speakers, but in the inexpensive but very good, with pro like features have you seen the Hsu satellites?

@erik_squires , thought HSU was primarily a subwoofer manufacturer direct entity...I am currently only exploring Yamaha because there's a Yamaha PA authorized dealer literally a couple of miles from my house, who does audio for all kinds of venues, it appears. The guy even offered to stop by my house and give me some ideas based on their stuff he's experienced with.

B & I emphases in the above quote = mine.

Up to now it seemed unecessary to bring up DSP, which is almost invariably a part of how modern Pro Audio functions. Hearing PA speakers in situ means what you see is not everything that you hear / get. This should generally apply to both smaller local and largest scale tour kit, but perhaps I’m mistaken?

Increasing numbers of studio speakers (actives) and small / multichannel home audio devices (power’eds) do similar. Only hifi speaker models for “traditional” home stereo seem to remain largely hung up on the purely passive approach.

PA playback of the nature OP seems to seek may well be:

To DSP or not to DSP - that is the [relevant] question. 😉

You mention off axis response. Pro touring speakers are designed with relatively narrow dispersion intentionally to concentrate that acoustic energy so that it makes it to the back of a large venue. It also helps reduce the smearing from side wall reflections. If you widen the dispersion - you diminish its “throw”. If you’ve ever walked around a venue doing a sound check - moving just 5 feet in any direction you’ll hear the sound change - sometimes dramatically. This is due to the phase cancellations of the multiple speakers throwing a narrow beam of sound. You don’t notice it during a show because you’re seated in one place. Move around before a crowd gets there and it’s pretty remarkable. So, pro speakers in home - unless it’s a very large room - may seem “beamy” relative to home speakers.

 

Speakers x room? Size/potential of both (plus the power kit). I’m hazarding the guess that Ozzy playback venue was not much like a living room or bedroom. Most venues are unlike most dedicated listening rooms, too, as I cannot think of a commercial venue for live music built the same as a typical residence. Not just size - wall/floor/ceiling composition, furnishings, (audience?) etc.

@mgrif104 , @benanders

Essentially, i have 2 rooms in my basement (no WAF restriction), both of them fairly large, ~7200 cu.ft and ~5000 cu.ft for audio. It could go in either room and the only issue for either room is a lower ceiling height @ 8ft (since it’s a basement).

Here are some models spec’d with a 30/30 on the horizontal and 20/20 on vertical, which should preserve sufficient perception of spaciousness, etc for a solitary sweet spot... and mitigate floor/ceiling issues to some degree for my space...in theory. The latter one’s tweeter is crossed over down to 1.8khz,  it appears, which should present a significant amount detail/resolution... in theory (due to the tweeter/small driver playing that low)...couldn’t say anything for sure until it’s setup and heard/audited.

 

For higher WAF and something pretty/real sleek looking, price shoots up to 20k all of a sudden ( 😑 ), i.e. some advanced beamforming home speaker design...

Interesting discussion. Two quick thoughts.

First: Generalizations are only occasionally useful :)

Second: Your own listening habits and hobby goals have a big role in what equipment best serves you. There’s a parallel in the car hobby. People have daily drivers, but also some other car(s) that they drive only on nice days and often spend more time tinkering with it than actually driving it. Ask that person what they expect from the experience…and you’ll get a different answer for the daily driver or the garage queen.
