Bad idea to use pro Tannoy speakers for home use?


This may possibly be a dumb question, but I found "pro" model Tannoys for sale, that seem to have the same drivers of much more expensive Tannoy home models. Specifically, I'm referring to Tannoy V300s.

Is there any reason I shouldn't use these speakers in a home environment? Apart from aesthetics which are arguably awful? They are referred to by Tannoy as sound reinforcement speakers and are apparently the same as used in the Sydney Opera House. I figure they must be high quality given that installation, but again - open to being told why I should walk away. I have other Tannoys - just need others to replace Magnepans going out the door (not suitable around my new baby).

Thanks in advance!

@Ddd1 - As it turns out, they don't look bad in person at all. They certainly wouldn't win a beauty contest, but overall, I'm content with the way they look. Now having a pair that seem to have been well taken care of, many of the pictures on the web seem to be of somewhat abused cabinets which is probably because of the nature of their intended use.

As for bass...so far it doesn't seem to be lacking at all. I was testing them this evening and the drum intro of a Pink Floyd track startled me it sounded so big and real. Keep in mind, I rushed to even get them set up so I could listen to them before my son went to bed, so I certainly haven't put time into them yet, but I'm happy with the purchase so far. I would have listened to them earlier/more, but I had to assemble Speakon connectors to some old cables (after first locating some at a local shop), as that is the only connection option.
I like they way they look. Question is do they go deep enough in the bass or are subs needed? I live in Canada and don't seem to be able to find any steals on them around here.
Update: I ended up buying them - just picked them up today.

Will report back on the sound once I hook them up and spend some time with them.

Thanks!
@Islandmandan - I thought about the custom enclosure thing and then convinced myself that I would never get around to it! I already have a bunch of other projects around collecting dust so to speak!
@Bombaywalla- thanks for the post. A trial would be great, but they are coming from a private seller. I currently own two SS amps that I would try and pair. One is an integrated Krell with 150w/channel and the other is a McIntosh with 200w. The 500w per channel recommendation for the V300s is what was worrying me (making me think I don't have the equipment to handle them). I don't want to have to buy another amp! (or sell mine and find another)

I also worried that I wouldn't get low volumes out of these at all because of what they're made for (BIG spaces).

And the other concern is that I should just buy consumer Tannoys or a straight set of DMT IIs which I found available. As in, maybe I'm going overboard with the V300s. They just seem like such a steal...the cost now vs new cost is ridiculously discounted.
@Map - The V300s are definitely heavy (75lbs each) but they are supposedly designed to perform equally well lying in any position (including on their side), so figured I could do that. Or, I have options to mount them or otherwise in completely inaccessible places. The Magenepans - wife wants them gone - if we could rubberize (for baby proofing) the entire house, she would have me do that as well! There is also the issue of him ruining them which I would expect would be quite easy. Anyway...I've had them forever and they are hard to find at place for because of their size, etc.
Its as good an idea as using any speakers you like that can be had for the right price.

You might want to give them a good cleaning with antiseptic wipes once home. Who knows where they've been? :^)
A friend of mine has a pair of 15" Tannoys (not sure if they are Golds or HPD's) that were part of the sound reinforcement for the musical "Cats" on Broadway. They served the entire run without issue.

He put them in custom enclosures for home, and is still using them. I'm doing much the same with 12" HPD's.

May not relate, but close.

I see what you are saying....
my DMT10 Mk2 have a specified sensitivity of 94dB/1W/1m & they are rated for 250W RMS & 350W peak, if memory serves me correctly. my speakers do get loud in a hurry as i turn up the volume control (as expected) but my DMT10 Mk2 do not distort at the higher volumes - they maintain their composure & then some. These speakers sound even better with a high current amp (I tested this in my primary system). So, don't let the high sensitivity lull you into pairing these speakers with a small or modest amp. Pair it with a high current amp & don't excessively kid-glove this speaker - it's meant to boogie without losing its composure .
I believe that these pro monitors like the DMT10 were designed to operate in sound-mixing rooms which trend toward anechoic chamber type acoustics meaning that all/most the sound has to come from the speaker without much/any help from the walls/ceiling/floor, etc. I suppose these sound mixing rooms are done this way to get a truer feel for the actual music without anything else getting in the way. The mixing-wallas must be cranking the volume during the process hence the high max power handling rating.
In a similar vein if your pro speakers are meant for public spaces then they'd want max volume with min amp power (to keep cost & heat generation down) hence the even higher sensitivity for the V300 & the even higher max power handling rating.
I've found the dual-concentric design to be really very good - i can sit on the floor with my ear under the driver height or stand up with my ear well above the driver height & not hear much change in the sound. Reading the manual informed me that the sound pattern was a 90 degrees around the dual-concentric driver. I believe it!
I found the sonics to be very true - no sugar-coating (which is OK with me) - and well very well balanced. No part of the audio spectrum sticks out giving the sound a cut-from-one-piece-of-cloth sound. After I installed the speakers in my 2nd system & turned on the music, I did not do a "wow" (as I was expecting myself to) but as I kept listening, i discovered all the music was there in its right form. And, that was the "wow" for me - it wowed me by just being true to the music. I also found out that my DMT10 Mk2 have a 1st order x-over, which is very much to my liking as I believe that 1st order x-overs have the least phase distortion (this parameter has a lot to do with listening fatigue when it is high with higher order x-over ckts).
Based on this I would recommend your listening to the V300. See if you can get a 14-day/30-day home trial. it might save you a trip & you'll only be out of a small amount of return shipping money. FWIW.
I'd be more worried about the Tannoys falling onto the baby or toddler or child than about Magneplanars. I have had SMG, MG12 and MG1.6 around children of all ages. No mishaps. If the Tannoys are very heavy, they could be much more dangerous than Magneplanars. (Internal bleeding, etc.)
I would have no reservations about monitors like yours at all (aside from the same "looks" issue!). I'm actually considering a pair as a different option. The very first speakers I ever had were Tannoy monitors actually (given as a gift in high school). There are so many write-ups of the monitors too, that it's easy to sort/weed things out just by reading reviews. These V300s though have a few unique issues. I can find almost nothing written about them (there is a little but not much, and some of it is about church installs and things like that). The specs are written up quite differently than consumer speakers (and therefore a tiny bit confusing). They actually recommend 500w for these things which doesn't make sense to me given their sensitivity (assuming I understand the specs right). And, finally - calling them "sound reinforcement" and Tannoy advertising saying that they are good for churches, clubs, PAs, etc. makes me wonder if they've been modified in some way as to make them bad for home. I'd just go listen to them, but they are about 120 miles away, so I don't want to waste time until I have more confidence in them.

i personally do not think it's a bad idea to use Tannoy pro monitors/loudspeakers for your home audio. In fact, I do the same - have a pair of DMT10 Mk2 speakers, which i think are really very good. Not as ugly as your soon-to-be V300s but reasonably close. ;-) but the sonics are fantastic & the looks can be overlooked & lived with (for me).
