Better performance, more clarity and sharper bass. I was trying out different wiring configs, and the difference was pretty big.

Yes you can really tell the bass apart.

I'm using the Q series and have a extra roll of 12ga wire, so I might give it a try this weekend and get a couple friends to come over for some blind a/b testing.

Bi wired my PSB Stratus Golds. Minimal gains. Bi amped the same. Moderate gains but less than I expected. Keep posting the findings. Im curious how it goes.

NAD M15 /NAD M25 / PSB STRATUS GOLD / PSB STRATUS 6C /DENON AVR 3300/CARVER TFM 45/35 - ANTHEM MCA3 / NAD T163
IMAGE DYNAMICS / INFINITY RS3 / POLK MONITOR 10/ALTEC 501 / INTEGRA 50.3/PARADIGM DSP 3400 / GOLDENEAR AON3 / HK AVI 200

I would like to share my experience with my system and my room. I did some experiments on biwiring, biamping and using jumper wire last year with my R900 using my yamaha receiver as a pre/pro and nad as my power amp. FYI, my receiver can be configured to biamp mode. To me biwiring and using jumper wire yields the same result. I noticed the tweeter sounds louder than when single wire was used. Biamping makes the tweeter even more pronounced than biwiring making them sounds brighter especially when I used the power amp compared to receiver amp. Since I prefer darker/warmer sound of my KEF, I went back to single wire again. Others may enjoy the result of biamping or biwiring as each has their own personal preferences.

Bedroom: Panasonic Plasma 42", Yamaha RX-A3020 AVR, Classe CP-800 stereo preamp, NAD M25 power amp, Fronts: KEF R900, Center: KEF R600c, Surrounds: KEF Q300, Sub: Paradigm Sub 15 + PBK, KEF Q400b + Antimode 8033S-II, Sony BDP-590 Blu-Ray Player, Dune Smart H1 media player.

If you had the Yamaha driving treble, NAD driving bass, no wonder there was a difference. You should use two of the same amps.

For those interested in bi-wiring and bi-amp their KEF speakers, the following article from Chuck Hawks will explain the difference between the three different setups and advise the correct way to carry it out.

HTB2 sub placement

I have an HTB2SE, and I finally just picked up a second sub, HTB2, on ebay to hopefully even out the bass response.

I'm going to try front/center with rear/center of the room, as well as both up front with 1/4 width placement. My question is, since these 2 subs have passive radiators making them fire in both directions, how close should they be to the wall?

Bonus question: Does anyone know the difference between the HTB2 and HTB2SE? I've looked all over online and even e-mailed KEF with no response. My SE sub actually says "HTB2" on the bottom - no mention of SE. However, it came in the SE kit, and it weighs just barely more (as indicated by the SE vs. non-SE specs). The units are identical on the outside except for one difference: the bass boost switch on the SE has 0, +6db, and +12db, where the bass boost switch on the standard I just got has 0, +3db, and +6db. If anyone knows what the actual sonic difference between these 2 are, I'd be really interested. I ran a sweep on both of them, and they seem to output the same.

My experiment was done with the same amp. Either with the receiver amp or the power amp.

Finally come to decision to order kef r300 left and right, kef r200c as centre, due to some budget issue, the sales person is trying to sell me a pair of kef e301 as surround back instead of the r100

I have a small living room, around 14ft x 17ft, sitting position is 8ft away from TV

I tried the kef r100 and thought that it's a great speaker for its size, and the r300 is fantastic, if I use the kef e301 as surround speaker instead of the r100, am I going to feel significant different or very minimal? I use the system for 70% movie and 30% music and concert. Or I should just stick with r100 as the surround back?

I have the R100 as the surrround back. Very happy with them. I suspect you will be disappointed if you go for the E301s. If you can afford the cost difference I wouldn't hesitate.

There is an important omission in the passive buy-amping section. If you buy-amp with amps that have different gain structures you will mess up the balance between the two sections.

Agreed. He wrote too much. "Go ahead, if you're deaf or deluded; otherwise don't bother" would have sufficed there.

Personally I wouldn't bother. Just use single channel per speaker.

Hi all,

I am replacing my EBay assembled set of old speakers with something a little more modern, and hopefully better. I replaced my old kef iQ2c with a kef iQ60C and got my hands on a set of HTS7001 for the back channels, replacing some Bose satellites I had.

My fronts are Kef q35.2 and are next up for replacement. I think the q35.2 is OK as part of the 5.1 setup when watching movies, but when listening music in stereo, they seem extremely metally and flat to me. I played with the crossover on the amp and it is a little bit better, but I have talked myself in deserving better front speakers.

I have my eyes on a set of R500's. Would it be wise to mix these more expensive R speakers with the Q front? Or should I get the cheaper Q500 fronts instead? I like the looks of the R500 much better and they have a smaller footprint.

The whole thing is driven by an Onkyo TX-NR535. Would it have enough oomph to make the R's (and the reset) sound how they should?

I am certainly not a specialist in sound, but like hearing good quality :-)

Thanks,

Richard

Keep the front three the same, but to lesser degree you can mix rears. I'd say Onkyo is borderline
