Hi, long time lurker here.

Have owned a full Q series 5.1 setup for around 8 years after seeing it recommended here.
Still thoroughly enjoying it on the daily!

We recently moved to a new home and I'd like to wall mount the Q100s I've been using as surround speakers.
The new room layout doesn't really allow for ideal side placement for the surround speakers, so they'll be going in the back.
On the left side behind our seating area there's a radiator, so the only option to have the speakers evenly spaced is to mount them up higher.

Ideally I'd like to have the speakers pointing down a bit towards the seating area, and perhaps toed in a bit too.

The speakers themselves come with a preinstalled mounting bracket, but I have no idea what I should be screwing into my wall to use those. Can't post a picture of the bracket unfortunately, as I don't have enough posts yet.

Here's a quick sketch for reference:

............................Q200C

...........|.........love couch ..........|
...........|...................................... |

--------------------------------------------------

I'd also like to know if I should set them up differently in my AVR now that I'm putting them in the back, to still have a good surround experience. I have them hooked on a Pioneer VSX-921.

Hahaha.... my 2nd kef 100 showed up in more than one piece as well.

Oh wait! Luckily I have another broken one here to fix it with from it showing up broken too.

Got the terminal plate switched out and giving it a listen. Started with tron, now on star trek. Trying crossover at 50/60/70hz, so far it sounds bigger than its size. But something in the tone sounds off. Maybe it's the flat response.

You guys really need to hear some diysoundgroup stuff 😉.

Wow, what are the chances of that happening? At least you had a "parts machine" kicking around.

I gave mine crossed over at 80hz, it's good there for me. I don't know what the crossover slope might be, but long enough that it's a nice blend. The Reference Model 100 does indeed have a very neutral, lifelike voicing. That's what I like about mine!

I've heard plenty of DIYsoundgroup projects. You have to spend a fair amount of money and do a lot of work to get results that are equivalent to and often better than the pedestrian, entry-level mass market offerings. If your labor is free, it's worth the effort.

The pre-installed bracket on the Q100's can be removed to accommodate a different type of bracket. Since you're mounting up high, and angling down, brackets such as these should work nicely.

Hi Ken,

Are you saying that dollar for dollar, entry-level mass market offerings outperform DIY Soundgroup projects? (By entry-level, let's say KEF Q series or Revel Concerta. I'd say those are some best in class examples.)

Also, curious as to which DIY Soundgroup designs you've heard. I've never heard any but find them intriguing. Especially after building several sets of subwoofers now.

Thanks
Dan

I'm not Ken but I can give you my experience with DIY vs mass market, I would include internet direct as well since many think of them as good price/performance. I had Chane A1 across the front for a few years and they were pretty good speakers but I ended up replacing them with Wharfedale Diamond 220s, which are $299. They were very close but the 220's slightly edged the Chanes out and looked a lot nicer to boot.

Next, I wanted to see what all the buzz about the RAAL tweeter was all about so I ordered some Mini Philharmonitors, which have the 64-10 RAAL. Since it used the Zaph ZA14 woofer, I had the idea to build a set of Zaph ZA5.2 bookshelf speakers which uses a cheaper titanium dome tweeter. I wrote a thread comparing the 2 but I actually preferred the cheaper ZA5.2, I think mostly because of the lower crossover point. I've since heard the Phil BMR and thought it was a good speaker but still wasn't impressed with the RAAL tweeter.

This is when I decided to try KEF, I brought home some LS50 but decided to buy the Q150 before grabbing the LS50 again. The Q150 wiped the floor with any of these budget offerings I had heard up to this point and up to anything under a grand including the Concerta2.

Since moving to the LS50, I have compared them to the BMR and Revel M105 head to head and still have the LS50. DIY and internet direct companies can certainly make good speakers but in my opinion, there is nothing out there that sounds more realistic or as natural as KEF's UniQ driver. I also guarantee you that none of the DIY designs or internet direct comanies is putting in the kind of engineering that KEF is, read the whitepapers on the LS50 or Reference line and you'll see what I mean.

Need some opinions on 3x LS50's for the front stage in a home theater setting. I was interested in getting a pair of used R300's because the new stock is all sold through in stores here now, but I don't see myself being able to find a matching R600c anywhere. The dealer here suggested I may want to give the LS50's a try instead since I already have a sub (SVS PB-12NSD). The LS50 on it's side for the center would also still fit properly underneath my wall-mounted TV sitting on my 16" stand as well. Would this be a solid option instead of the R300/600 combo or would it be lacking in comparison?

Try listening first. I was in same position and compared them and liked the r300 better. Ls50 was nice though

Well that's the problem, there's no R300's to listen to anymore. The used option isn't local, it would just be buying blind.

I completely agree with you about the scale and depth of R&D that companies like KEF and Harman have with access to spinoramas, anechoic chambers, sophisticated computer modeling, etc. This latest generation of KEF uni-Q, even the last one, is incredibly sophisticated and unique. As are the most current generation of waveguides used by Revel. And of course, those are all proprietary.

What I find intriguing about DIY, particularly DIY Soundgroup, is that while they don't have access to certain proprietary drivers, waveguides, and testing facilities, they aren't bound by budget. So if the crossover should have eight components, for instance, it will have eight components. If the cabinet should have robust bracing, it will have robust bracing.

Whereas, particularly when we're talking about sub-$1,000 mass market speakers, having one or two extra components on a crossover or maybe an extra piece of bracing for the cabinet, on a mass scale means thousands and thousand of dollars. Extra dollars the average consumer may never care about, but enthusiasts like us do. That is evident on the Q-series. They are very fine speakers--because of an incredible coaxial driver--but they could all benefit from better crossovers. The driver is so damn good though that they can get away with it.

By the way, I really liked your double blind comparison of the KEF and Revel speakers recently.

Yeah I definitely agree with this, also for people who want extremely sensitive and loud speakers, some of the DIY designs with horns aren't going to be matched by mass market speakers.

Thanks, I was definitely scared they were going to best the LS50's but I'm not really a brand person, I want the best speaker in my budget.

The Zaph speakers are not DIY Sound Group.

I feel like I probably have more experience than most with both KEF and DIYSG offerings. The first thing to keep in mind is that many of the DIYSG designs have different goals than KEF. Most of them are designed for home theater so they are high efficiency and controlled directivity first and foremost.

I really don't know which speakers I've heard that might have a "DIY Sound Group" heritage, I kind of ignore the 'sound group' part of that and consider just the DIY part.


Some I've heard are heavy hitters in mid-bass, others have really good upper range reproduction. I've not heard any that were as spectacularly balanced as something like a KEF R7 can be.

Well I have DIYSG speakers in my theater and KEF R300's for my two channel setup so I guess you can tell which I prefer for my music listening

But for theater and concert blurays, The KEF's cannot hold a candle to my theater speakers that are 3 ways with dual 10" woofers and 99db sensitivity.

Different job, different tool, thats all. One speaker cannot be all things to all people in all scenarios.

Most of them are designed for home theater so they are high efficiency and controlled directivity first and foremost.
I realize that, DIY group is basically an internet direct company that ships you kits to put together your own speakers and I'm sure they're pretty good for home theater, I just think huge woofers and compression drivers are unnecessary. My LS50's play in my small room at reference level with 1 Watt of power and my subs take care of the bass, the only thing bigger woofers and higher sensitivity is going to do for me is play at that level with 1/10 of a watt and since there is 0 benefit of crossing over mains below 80Hz, the large woofers are mostly wasted.

Now if you're aiming to impress noobs with 100+ db volume and tons of bass while doing it then yes I can see the benefit but otherwise I just use my KEFs for music and home theater.

Actually, the speakers are tuned to be crossed over at 80Hz. The large woofers and compression drivers are all about dynamics and low distortion and technically, "reference level" is 105db peaks for the mains and 115db with the subs . No, I don't usually watch movies that loud.

No need to insult people over something you don't have experience with. Not sure why there was so much defensiveness when someone mentioned DIYSG. Totally different speakers. Totally different goals

Enjoy your LS50's. I love mine as well.

No one criticized KEF so I don't know how I was defending them, I was just giving my general experience with various types of speakers since I've tried so many in the past few years. I realize DIY is very good for certain segments, especially subwoofers but many times on these forums when people ask for recommendations, many people proclaim internet direct to be the best bang for the buck and I just haven't found that to be true at any price level. I try to give an opposing viewpoint to balance it out a bit because this forum can be very biased. I've never heard any designs from DIY soundgroup so I'm certainly not criticizing them, I see they're in Cincinnati so if I ever do a dedicated theater I might check them out further.

I dont consider DIYSG to be internet direct. Im not sure I would even call them a business in the general sense. Businesses are made to make money, they are basically providing these designs and kits at cost!

The kits are created by a small group of people who are passionate about this hobby. There is no store front to visit. Its ran by a landscape business owner who does it all in his free time. Its all pretty remarkable really.

I have also heard many internet direct speakers and I agree, KEF is at or near the top in performance of almost any class they are in.

The dealer here suggested I may want to give the LS50's a try instead since I already have a sub (SVS PB-12NSD). The LS50 on it's side for the center would also still fit properly underneath my wall-mounted TV sitting on my 16" stand as well. Would this be a solid option instead of the R300/600 combo or would it be lacking in comparison?
In a small/medium room, absolutely! Having 3 of the speaker up front is the acoustic ideal. They're not super efficient so maybe not the best choice if you like cranking it up to 11, but will sound fantastic under normal conditions.

Different job, different tool, thats all. One speaker cannot be all things to all people in all scenarios.
Hi Brian,

I'm guessing from you're description you have the 1099's. (And probably Volts for surrounds if you went all in with DIY Soundgroup for your theater.)

Just curious, what is it about the KEF's do you prefer for two channel music? Are they a bit more accurate or neutral, etc.

And what is it about the 1099's that you prefer for home theater?

Have you ever listened to the 1099's vs the Kef's in the same room against each other or done any measurements?

Not trying to start any debate here at all. I've just been curious for a while about high sensitivity speakers for HT.

Thanks
Dan

Yep. 1099’s in front. Volt-6’s for surround and atmos. Currently in the process of swapping my Volt 6 surrounds out with HT-8’s.


I’m not completely sure why I like the KEF’s better for two channel. I guess it’s not totally fair either since I’ve never used the 1099’s for two channel in the same setup as the KEF’s. I would rather not have to move them though. They are very heavy and repositioning to the exact same spot is a pain.

The best way I can explain it is I prefer the 1099’s with LIVE recordings and I prefer the KEF’s with STUDIO recordings. The KEF’s also extend more in the treble and seem to have more “air” whereas the 1099’s have a more direct sound and roll off a bit earlier. I listen to a lot of jazz so that may play a role.

Different sources and amps to.

It would be interesting to do a better comparison in the same room but no, I’ve never done it.

Well put.

By the way, how did you arrive at 1watt for reference level output?

Not to belabor the point but DIY Soundgroup has kits with more than just large wave guides, woofers, and compression drivers. They've got standard dome and cone kits designed by the likes of Pete Schumacher and Jeff Bagby. The drivers are all solid and the crossovers are no-compromise. Its just a different avenue for those interested in dipping their toes into speaker design. Imagine Laurie Fincham or Andrew Jones designing a speaker, and selling you the parts to put it together yourself.

The Uni-Q is a special driver set, no doubt, and within its limits it's tough to beat. We all have different preferences, rooms, and equipment. Luckily there are a lot of high quality options at varying price points.

It's just an estimate based on the sensitivity of 85 db at 1W/1m. You lose a bit of SPL due to how far away you sit from them but you gain it back by multiple speakers playing and being close to walls.

I don't doubt DIY soundgroup is a good value but the reason I wouldn't chance it is because I don't see measurements of any of the designs, I've listened to enough speakers to know what I like in terms of measurements so they need to pass that test first. The reason I went with a Zaph design when I did mine was because his designs are all very well laid out with measurements and detailed plans on how to assemble the cabinets and build the crossover.
