Nicktx27,

It would better to look for more efficient speakers rather than a more powerful amp/receiver. If the speaker sensitivity remains the same and a 3dB increase in sound pressure (loudness) at the Main Listening Position (MLP) is required, then the amp needs 2x the power. I.e. 90W ---> 180W. A 3dB increase in loudness is just noticeable by most people. For a doubling in loudness, there needs to be 10dB increase in sound pressure. Unfortunately that means 10x the power requirement, i.e. 90W ---> 900W...

Wow!
Well, I'm trying to do the room on a fairly modest budget. My quintet II sound really good in that room. My sub is the PSW505.
I'm mainly looking for something that will give me good crisp sound for movies and games, that is slim and on wall for mounting behind an AT screen. Not really looking for reference sound right now.

ETA: so the 301s freq range is 80hz-30khz and my sub is 23hz-160hz. If is set the crossover at 120hz I should be ok. I'm pretty sure that's what it's set to now.

Planning to post this message to the KEF, MA and Canton threads. Hate to spam the board but definitely interested in everyone's perspective.

I'm narrowing down my speaker search and KEF are on the short list. At roughly the same price, here are the KEF and non-KEF options I'm considering. Please rank them from best to worst, or give you opinions. I will be connecting them to a Yamaha rxv1075 and mostly listening to Vinyl. But also some CDs, movies and sports. Here's my shortlist:

Monitor Audio Silver 6
Canton GLE 490.2
Canton Karat 770DC
KEF Q900
Canton Chrono 509.2
Canton Ergo 607 DC
Monitor Audio Silver 8

For what it's worth, my wife prefers wood tone to shiny black/white, so all things being equal I'd lean that way. But, ultimately, my main consideration is sound....especially vinyl (everything from jazz to classical to old school funk to punk, metal and garage rock). I may want to add a centre channel later but for now going 2.0.

thanks.

From my listening I would say the q900's would best the monitor 6's but I would suggest you listen to the cantons and the monitor audio 8's and the q900's before you decide. They all have characteristics that you will need to listen to for some time and make a subjective listening decision .

Nicktx27,

The F3 (-3dB) point on the KEF E301 is actually 90Hz. KEF recommends not going lower than this - higher is okay...

Any modern AVR will determine what the F3 is going to be in the room. Using the E301, if it is below 90Hz, you would need to manually adjust it back up. If it is higher, then leave it as it is.

As an example in my room, on the AVR, Audyssey had determined the F3 settings are:

Fronts: 60Hz
Center: 100Hz
Surrounds: 60Hz

I went into the menu and manually adjusted the crossover so that all are at 100Hz. Using REW, I then ran low frequency sweeps (15Hz to 300Hz) at various sub distances with the center channel to see where the smoothest response at the crossover would be. Best response came out to be -1.5' from the default setting.

Once I figure out how to post pictures into AVS, will include a graph of this.
Edit: 19-June-2014. Tried to up-load the sub-distance tweak picture.

Interesting. I'm still torn and cannot find anywhere to audition these darn things. I'll have to try again once I get back in Houston. There is a place called Haylcyon, I think. Appreciate the info and look forward to your graph.

I am also rethinking the amp situation, leaning towards the NAD integrated that has had great reviews.  This should be sufficient at 50 W/C to get the best from the Q700's and their 88db sensitivity, correct?   
Well, I went with the Q700's because the 900's were just too big. I got a great deal from a local shop and set them up on Saturday. HUGE difference coming from the Q35's, as expected, especially with the bass. I went with the rosewood finish which I think looks more furniture-like, and they look and sound fantastic. Would the Q900's sound better? Likely. Am I happy with these? Absolutely. I was curious about amp requirements but my Denon stereo receiver with 60wpc is driving them easily so my plan for an integrated amp at 45-50 wpc won't be a problem. I'm still trying out various CDs to see how the speakers perform, but quite impressed so far - they do a great job with Ray Lamontagne's Till the Sun Turns Black and the gritty resonant vocals, Miles Davis, Gorillaz, Laura Marling - all good, but I may still ad a sub down the road.

I'd go for R series over Q tbh. Q900 probably similar in price to R300.

Krell Evolution 900e x 7

Bose Jewel speakers.

 

Jealous of my speakers?

Hey guys. I'm just getting into the audio side of home theaters and have decided to go with Kef Speakers. I just ordered the following for a 7.1 setup:

2xQ900
2xQ600c
2xQ800ds
2xQ300

I have the Denon X4000 receiver. Will it be able to power these speakers ok? I was hoping to get by without an external amp if possible. I read an article where the Q900's should be rated as 4 ohm speakers and it has me worried.

I would really like to here your thoughts.

Thanks

The X4000 can handle 4 ohms too. If you are perturbed, just set all speakers to small, XO to 80Hz, and let the subs do all the heavy lifting.

That's exactly what I was thinking of doing after have read through the forums. Thanks a lot! I appreciate it.
