Infinity Primus Owner's Thread - Page 111

Hi DavidSee, best I can come up with is $200 ea. (wwstereo).

Thanks!
Thinking of pulling the trigger along with the P351.

Did electronics expo stop carrying this line?

I believe so otherwise they would list the model with it as out of stock.

FWIW, I've opened up one of my new primus 363 towers and have started tweaking it , documenting the progress at http://www.diyaudio.com/forums/multi-way/215759-zobsky-tweaks-infinity-primus-363-floorstander.html . More pics forthcoming

You are listening to your room. The NAD C720BEE seriously underpowers the 363s. You need a sub and some form of room correction. It is impossible to take your observations and comments seriously because I have heard them properly driven (without all of the modifications) and your setup does not fall into that category.

Hi zobsky, sorry not register at that forum ... please post pics here as well, thanks.

FYI, P153 @ newegg $50 ea.

It might seem like that , but in this case , I beg to differ

We listened to the speaker in 2 separate houses paired with about. 4 different amps ( 7 watt diy push pull 2a3 amp, the NAD, a 85w hybrid tube amp and a 100 + w yamaha aventage HT receiver ) and compared to 2 other speakers (a DIY selah sealed monitor and a big rebuilt set of RadioShack mach ones ( which was underpowered by the smaller amps)) and I stand by my conclusions ie the primus is good but can be imProved significantly

Maybe I'll hook up the big Macintosh next with the minidsp inline to tweak the parametric eq

Will do so on my blog later and post a link
Thanks

I am new b to HT recently I am in market to build one and am reading lot about on this formum.
As of now their is very good deal going on Infinity Primus (P363) and Pioneer A Jones series (SP51)
Both have got very high review on forums
Almost same in size
Same price level

I have to decide one out of this two series and will appreciate feedback from someone who have reviewed and heard both

Unfortunately at this time I dont have any store nearby having both of this series

Your help will be highly appreciated.

Thanks

I e only listened to the pioneers briefly, that too in store
Aesthetics: the pioneers look a bit goofy with their hard grills
Sound: it's been a while and I heard the pioneers in less than optimal conditions but they seemed to be voiced a bit more neutral while the infinity 363 definitely have a bit more "character", though not in a bad way

Personally, I'd pick the infinity if it's on sale, and modify it

Great thread there - I'm eagerly following your progress.

I think bracing and dampening is going to take a lot of trial and error. I suspect that the speaker was designed as is for cost reasons but also to boost the mid-bass, which is common in this price range. It may take some work to get just the right balance of bass weight and mid-bass without bloat.

As for the caps, I am also in the "it doesn't make a difference" camp, but I also say that as long as you're in there, why not? Kind of like modding a car - a little bling never hurts.

I also agree that the NAD should be a good match. It's not underpowered.

Good luck and have fun!

My thoughts exactly. Klipsch did the same with the klipschorn bass module, .. So why shouldn't infinity.
I've decided against adding extra bracing for now mainly because it's a bt of a pain to jam a side to brace low down in the cab where it really needs it. I know a couple of tricks to achieve this but I'll reserve this for when I next open the cab up ( can't do that too many times with these mdf cabinets)

My AV PC recently died so I unfortunately can't take any measurements. For Now, I'll start on the second speaker

And I will post pics soon..

FYI, Amazon has PC351 for $199 (wwstereo is oos).

Anyone wall mounted their P163? What wall mount is best for this heavy thing?

Can't find any pic of the back ... does it have standard 1/4" - 20 mounting thread?

It does not have a mounting thread on the back, it's too heavy. I would recommend these mounts: http://www.amazon.com/Pinpoint-AM-40B-Clamping-Bookshelf-Speaker/dp/B002UV03MW/ref=sr_1_5?ie=UTF8&qid=1342021982&sr=8-5&keywords=speaker+mount

Hi guns&motorcycles, thanks ... anyone else with another brand or option? Or is it best to go with four P363 as surround?

If you have the floor space, then go with 4 P363s for your surrounds because they are more easily moved around. Otherwise, the suggested mount will work. I know because I use a pair of them. But they must go into a stud and will easily hold any of the Primus bookshelf speakers.

Hi fookoo_2010, thanks ... almost tempted to go ahead try it since its on sale again for today (One Day Sale).

Can't pull the trigger, now Fry's has P153 for $50 ea.

Or should I wait for sale on P163?

If it is an economic issue for you, then go book shelves. The ideal setup with respect to speakers is to have the same one in all 7 positions. If you have P363s as your fronts, you have the opportunity to at least have them in six positions. The center speaker can present a problem because a floor standing speaker maybe too tall for most user's display and hence they go to the same speaker but one that is oriented horizontally - a theoretical disadvantage. But one would at least have the same drivers in all seven speakers. Why four drivers versus two? The ability to move more air. The flexibility of floor standing speakers is that they can be moved without a hassle, either horizontally or vertically and not have to deal with a stud supported speaker or having a pedestal type stand (an additional cost and probably more than the suggested mounts and up there relative to the cost of the speaker). With 4 additional P363s, you have the opportunity to set up an ideal system at a bargain basement price.

^^^ didn't want to rush my decision on the P363 as I'm certain it'll probably be on sale again at Fry's.

If my MLP is about 3' to 4' away from surround side, would P363 be to close? And would it be still give off the surround sound effects more encompassing?

I already have 4 P363 and center PC351.

No, raise them so that the tweeters are not at ear level. For P363s, consider an inexpensive, small table from Ikea that is 17" high and use it for all four surrounds.. When it comes to audio, it is a matter of preference, just how good your version of audio room correction is, and what you want in terms of sound stage width and height.

I don't see the need to go with 6 p363's so I was wondering what everyone is running with the p363's. I am upgrading my rear channels and prefer a more traditional set up. The extra floor speakers just seem weird to me. I was looking at the 163's but is there something right at the price point of about 400-420 or less that will work for these speakers. I have the 363's and the 350 center and need 4 rears. Just wondering if there is something I missed as I kind of get tunnel vision and have only focused on the 163's after looking and the Bic dvi-62s. So maybe I missed some other speakers that are compatible. I will be running a 200w amp (this is why I am looking at 150-200w speakers) through two of the rear channels(surround L&R). The other two channels(back L&R) will be driven through the receiver. Will be purchasing the week of July 27th
Thanks

Thanks D-bag. you are so smart and high and might that you can't justify a civilized response that is right your time is so much more important. Oh wait you actually responded like an A$$. Self import jackhole I was ask for a bit of help not a response from a pompous A$$

I would keep it in the same lineup. Get 163's or 153's. Matching the surround is not as important as the front, but I would do it anyways.

Cool Thank You. I was thinking that but I thought I may have missed some speakers that might work well. I was leaning that way because I was worried that if the timber was off from the front channels to the rear channels I would notice it. I figured that the p163 would be the best match. I tend to lean the way you do and try to match them all except for the sub.

Thanks again

The author of the book designed the Infinity speaker. Obviously, you are not all that serious about audio and know it all.

No I am not really serious at this time this is a fun hobby and I do it so I can enjoy watching movies. I am not designing a huge Home theatre room nor am I working with thousands of dollars of equipment. the money I spent in upgrades for an entire system is nothing it is nice but many people spend that in speakers alone heck sometimes for just the main L&R. When and if I design my actual home theatre I am cover I will get a crash course from a customer of mine who designs large high-end home theatres. Until then I will pick up a bit of knowledge here and there and let my receiver figure out the acoustics of my room. Until I have a dedicated Home Theatre with a projector I am not to concerned about acoustic panels and all that. If I notice something that is really bugging me the I will do it. Like when there was a little buzzing coming from my rear speakers because the vibration from the speaker was making the wall vibrate. So I added a strip of foam to kill the vibration. Other than that I am not looking to get all advanced. I understand you may like people to read that but I have no interest in a manual on sound concepts and design. Like I said I not saying it's not a good book I am just no where near that level so I will never end up reading it or implement any of it for a few years. Not to mention dude if I knew it all then why would I have even posted anything.

Hey I was wondering is anybody using an external amp with the 363's. I have been looking into a 5 channel amp. I know I don't have a huge room or nothing. It is actually a bedroom set up right now. Next year it will most like either be put into a dedicate movie room(not HT room yet) or as a living room set up. But I was curious I always listen to movies at reference level and watch movies quite a bit. I was wondering if people do use it with them and do you notice a drastic difference. I have read that base on the speakers and receiver I have they are being driven well. And some people say that highly sesitive 8ohms speakers don't necisarily need and external amp. What are your guys thoughts or experience.

Thank You
