Hi everyone

my receiver is an onkyo tx sr-875 and i'm using it on B&W MT-30 but... just made an upgrade with B&W 802D's and a Classe CA-2200 amplifier

now they are all running on the onkyo receiver and i am very pleased since i am using them in a 4.5m x 4m room and i don't need much more power than this. the music sounds perfect just on the 802Ds and the movies put out everything they can on the mt-30s (now together with 802D). i am using my computer soundboard (proffesional) as a source. anyway, everything is a new experience now since the 802Ds are "undressing" the music i used to listen to and got me discover some new sounds to the tracks i thought i know. that's a wonderful feeling

my next upgrade is going to be a good source and then who knows...
anyway, now, with all i got (front-802ds, center-sides-rear-sub-mt30, receiver-onkyo tx sr 87, amplifier- classe ca2200 ) i want to take the sound quality to perfection as much as possible by setting the receiver according to the speakers and amplifier specifications.

i've read the manuals, i made tests and my final settings look like this:

speaker impedance 4ohms,
front (802Ds) 200hz
center 60hz
sorround 80hz(thx)
sorround back 2 channels 80hz (thx)
lpf or lfe 100hz

subwofer (pv1) is set to 60hz (i noticed that the bass sounds cleaner using this setting)

are they correct? is there anything else i should change?

are theese speakers too much different? can i get a worst sound if i run them together? may they damage somehow if i run them on these settings?

thanks for your help

Hi there
I wouldn't put a crossover to 802D... You are loosing all the bass from these 2 superb speakers!! Leave 802D (as front speakers) without crossover, leave PV1 without crossover, and you can put a crossover to the rear speakers... You have to think that front and center speaker gives you the 90% and the rear speakers only the 10% of the details...Also, if you want a big difference in music, use only lossles or flac compression to your music!! Somewhere in this forum I remember "wettou" posting a site with music in these compressions....

I think most, if not all, B&W speakers are 8ohms.

The 802D crossover should be set at lower than 50 Hz, if at all. (I assume you are referring to the crossover to the subwoofer) You will need to decide on the exact level according to your preferences in your listening room. However, 200 Hz is definitely way too high.

Center channel: What are you using as your center channel? The M1 can only go down to 80Hz. If you are using M1 and setting crossover at 60 Hz, then your center channel is missing the sound from 60 Hz to 80 Hz, which is a big problem. On a side note, if you are indeed using the M1 as the center channel and pairing it with the 802D as the Left and Right, then you are having a very inconsistent sound stage in the fronts. Let me suggest that you try not using the center channel and see if you may like the results better. If budget allows, get the HTM1D or HTM2D.

LFE: I am not familiar with Onkyo, but I thought the LFE channels are always lower than the subwoofer crossovers. If I were to set it manually, I would set it at 40 Hz since you have the 802D as fronts.

PV1 Crossover: How are you connecting your PV1 to the receiver? Are you using the "telephone wire" or the coaxial cable? If you are using coaxial, and I recommend that you do, then the crossover on the PV1 itself should not matter because it is overwritten by the receiver crossover.

Now it looks like the sound is perfect!

I made all the modifications and the sound is stable and strong on every track i listen to. most of them are Flac, wavs or 320kbs Mp3 so the quality is as good as possible.

Now my settings look like this

Impedance 6ohms
Front (802D): Full band (60hz is the lowest but it sounds almost the same)
sorrounds including center(M-1) are all 80hz (THZ)
subwoofer is set to 60hz (coaxial connection)
LPF LFE: 80hz (The lowest)

:T

Now i really should be thinking about buying a much potent center speaker than the m-1 that's true. it's not making a good job with the 802d around hehe

many thanks 8)

WOW, you are using possibly B&W's cheapest speaker as a center with one of its most expensive as fronts. 8O

The 802Ds deserve at least the HTM2D with the diamond tweeter. If the M-1 is the only option you have, then you're MUCH better off just using a "phantom center" channel with your 802Ds. :T

Well I've just purchased them recently so i never really thought about it since I am mostly listenening to music in a relatively small room
but still it's painfully true

it really feels like a bigger center is needed.
now i'm thinking about paying my dealer another visit... like he doesn't know that i will be coming back

No worries, I've heard the M-1 and it's not a bad speaker, and definitely great for value. In fact, my Zeppelin uses the same midrange and tweeter as the M-1, and I think it sounds great for what it is!

Just that you have incredible speakers in the 802D (got mine last week, but the installer isn't coming until Thursday now so still haven't heard them in my home!) and I know you'll get much better performance out of your entire system if you use a "phantom channel" with your 802Ds or get a matching center!

In my opinion, leave M1 as center, and when you get enough money, you can go to HTM2D!!! Because you will need also another amp, so??? From the moment that you use this system more for music, you don't need HTM2D... If you buy HTM2D you will have to buy also CA-3200 and then the rear speakers M1 will have to change them also!!

**tudorvok** · 04 March 2009, 23:17 Wednesday

yes, i forgot about the amp

. in this case that would be too much for me and for the space in my room... the htm2d is big and also the amp... however i watch movies about 20-30% and the rest is only music so i would consider upgrading the center to a higher model (than m1) which can be powered sufficient from my onkyo receiver...

Have you tried the setup in phantom centre mode?

I use HTM7 with 804 with satisfactory results. Your receiver lacks the "high current power supply" of the TX-NR905 so it would likely sound ok at best with the bigger centres. I would stick with the phantom but if you really need a centre then a HTM4 would be easier to drive while being better than what you have.

**tudorvok** · 05 March 2009, 18:34 Thursday

Yes, the quality is much better now. it was mentioned in the manuals (phantom mode) too but i didn't imagine that will be very different or even better than having a hi-fi center speaker. the difference is huge... clear and more defined sounds come exactly from the center, especially when watching movies (conversations, etc...)

i am wondering if the HTM4 can do better than this ...

**planitismetal** · 05 March 2009, 19:14 Thursday

Look, in my opinion, from the moment that you have 802D, you have to go to a HTM2D... You have to know that the front speakers and the center must be the best in your setup!! Including sub... 8O Everything has to do with money... Then, when you will change center, or put center speaker, you will notice that you have to change also rear speakers!! :B :B :B :B
Your money, your choice!!! I know that it is great to have a system like this!
Here in Greece we have an expression: slow slow... Everything in time!!!

I am telling all these because I am soooo close to order now 802D, HTM2D, ASW855, and CA-3200 :rofl: :rofl: :rofl: :rofl:
BUT I HAVE TO WAIT!!! WAIT!!! WAIT!!!! :Z :Z :Z :Z :Z :Z
