Hi I am upgrading my home theatre and would like some ideas on completing the upgrade.

I currently have a:

Samsung PS63C7000 63" 3D Plasma (just bought)
Samsung BD-6900 3D Bluray player (just bought came with the TV)
HDMI 1.4 High Speed cables
Pioneer SxD510 receiver
Infinity Delta 30 fronts and center
Jamo Sw708 sub woofer
Jamo Artisan rear speakers.

I am upgrading to a 7.1 system and want some input on:

Receiver (Onkyo SR608 looks good)
Speakers...should I......1 Get a complete matching new set..Jamo or? or 2. Keep the Infinity's which are in excellent condition and get 4 satelite infinity speakers and infinity sub to get the 7.1 system all matching?.

Room size is 18ft wide x 20ft deep

I am in New Zealand so everything is not available here and is expensive compared to the US

Any help appreciated

Welcome to the forum :wave:

I currently have a:
Speakers...should I......1 Get a complete matching new set..Jamo or? or 2. Keep the Infinity's which are in excellent condition and get 4 satelite infinity speakers and infinity sub to get the 7.1 system all matching?.
I can't find any specification information for the Jamo Artisan... I found this for the sub:

Type Subwoofer
High frequency response (Hz) 150
Low frequency response (Hz) 55
Weight 8.0 kg

If that's the case, I suggest you to invest the $$$ in a better sub (if you can afford two will be better :innocent:). Apparently the sub response is not good enough (lowest frequency is 55Hz), you need something that can go down to at least 35Hz...lower is better.

Depending on the specifications of the Artisan, probably they'll be okay as surrounds.

If you're happy with the Delta, and you're matching L+C+R speakers you're okay, You don't need to match all speakers :T

Thanks for the welcome and reply

The Jamo Artina rears are a wall type speaker:

Long term power 50w
Short term power 60w
Impedance 8 ohm

There are white and a bit discoloured from the sun. Do I use 4 of this type of speaker to complete the 7.1 or do I use a different style of speaker for the others?

I am happy with the Infinity speakers they are about 8 years old but look and sound like new.

If you have 2 subwoofers I pressume you get 2 the same and have them either side of the fronts?

cheers

Those infinity look nice (I'm sure they sound nice too)...:T

Do you know the frequency response of the Jamo's??? If you're using the 80Hz as the crossover frequency to the sub, your speakers need to play down at least to 80Hz, or you'll have a gap between sub and speakers...

Depending on the frequency response of the Jamo's, probably will be better to get four similar speakers for the surrounds, if you can afford to get all Deltas will be nice...but four similar speakers will work fine too. :bigsmile:

If you can buy two similar subs, or at least with the same specifications (I used a Velodyne VRP1000 and Infinity TSS750 at the same time, they have similar specifications)...you can place one on each side of the fronts; but if you want to do it right... you need to find the best sub placement using the crawling test (place sub where your main seat will be, then crawl around the room until you find where the sub signal sounds better...)

Thanks guys.

I would love to get some more Infinity Delta 30's but being an older model now I am probably out of luck :rubeyes:.

Would Infinity Primus 162's be a good match for the Infinty Deltas and is a Onkyo SR608 a good match?

Also I will look at getting 2 x new subs would 2 x 250w be the right combo?

I think I will import the speakers from the US, may have a little trouble with the Subs as we are 220v here.
Can you rec a good place to purchase from

The stuff is just way too expensive compared to the US by the time everyone puts there hand out along the way

Thanks again

I'm sure is okay.

Is not critical to match the surrounds with the front speakers... so, any speaker will be ok, as long as it plays down to at least 80Hz :T

Also I will look at getting 2 x new subs would 2 x 250w be the right combo?
That's okay... mine were 150 RMS, until I build one (that's another option for you :whistling:)

Take a look here ; this are some of the most popular sub... they have a dealer in your country (I'm not sure about prices and your budget, but you can start with one and add another in the future) :bigsmile:

Sorry also will look at Krix but my first choice would be the match everything up.
I recommended it because it's supposed to be a very nice speaker company based in australia, which is close to new zealand isn't it?

Also I will look at getting 2 x new subs would 2 x 250w be the right combo?
This doesn't tell you much - there's so many factors involved. There's a 10" x 100 watt sub that i've heard people say beats the 12" x 325 watt PB12NSD in both output and sound quality.

Australia is 3 hours away by plane so still quite a distance. Also the exchange rate between the 2 countries is not good for me at present so it is way more economical to get stuff from the USA.

The SVS gear looks good

I will buy the receiver here so I don't have any voltage issues. I think I will get the Onkyo SR608

I have seen some Velodyne Subs here at a good price and they seem to have good reviews so maybe that is my best option. The decision is whether to get 2 x 10' or 1 x 12 as my room is a good size

Then all I will need is some satelite speakers and I will be away

Heres some specs of the Veodyne. I can buy this for $1000 NZD in NZ
The SVS units look real nice but when you factor in the AUS $ (currently .76c to NZD) and the freight and GST (tax) I would have to pay I would say the SVS Unit would cost approx $1900 landed here. Big difference when you are thinking you may get 2.

Looks good... Are you buying one or two???

Have you considered the DIY option??? You can build a killer sub with that money...

I build a sonosub, it was my first build... I spend around US300-350, if you add the amp total will be around US500-600

Thanks guys, no I haven't considered building one...not sure if I have the patience LOL

I bought a Onkyo SR608 today so thats taken care of

I am still thinking about 1 or 2 subs, here is another Velodyne that could be worth doing 2 of as these are not too badly priced at Retail $899

* Woofers: 10-inch forward firing
* Magnet Structure: 5.6 lbs
* Frequency Response: 32 - 140 Hz +/-3dB

* Cone: Coated Fiber Cone
* High Pass Crossover: Full range
* Low Pass crossover: 50 Hz - 200 Hz
* Cabinet Design: Acoustically neutral, down-firing ported
* Outputs: Stereo, left and right, speaker level
* Inputs: RCA Line Level, LFE, and Speaker
Level inputs
* Auto On/Off: Yes

* LED Power Indicator: Yes
* Shipping Weight: 13.6 kgs
* Finish: Black ash wood-grain with black gloss trim
* Dimensions (H/W/D): 13.75 x 12.75 x 14.4 inches

Maybe 2 x 12's would be an overkill

Believe me... there's no such thing :innocent:

The more bass you have... the more bass you want :bigsmile:

Currently I'm using a sonosub 15" (I upgraded from two 10"), and I wish that I have the space to use at least one more :whistling:... to complement the sub, I'm using one buttkicker on each row of seats :T

Also can get Polk Audio RT1 A1 and F/X1 A4 surrounds for the same price as the Energy CB-10 and CR-10 Surrounds.

Which speaker will work best with my Onkyo, Velodyne and Infinity Delta 30 fronts and center. (The Polk look more like Infinity's) but I can live with the look of the Energy's

cheers
John
