Printer Friendly Forum Posts - Opinion on Infinity and Adire Audio

well its come time to replace my trusty old rockford sub with something a little newer, and i was looking for some opinions. i am currently considering either 1 or 2 Infinity Kappa Perfect 10" subs or one Adire Audio Shiva 12" sub. i have never physically heard a Shiva before, so i have no comparison between the two. the box will be a sealed box, amp will be whatever is needed to adequately push the sub(s). i am mostly looking for SQ, but also be able to turn up the bass whenever i need to impress someone. i will not be getting 2 12" subs, so the 2 sub option is only for the 10's.

thanks to any opinions, as that is all im looking for!

Well I can give my opinion, but it is slightly biased.

When the Shiva first came out, it was mostly compared to the Perfect's performance, but at a much lower cost. It was designed for the ultimate in cost per performance as not one dollar was spent on it if it didn't help the performance. That's why it looks kind of plain. But performance wise, nothing can touch it even close to it's price.

Ditto. I love Adire products. Very favoably comparible to Infinity Kappa line.

Well here goes my opinion, the Shiva is an awesome sub for the price. I have a couple of friends who have 'em and they sound really really good. The SQ is very good especially for the price, I don't think that their is a sub out there that can compete with it in the same price range. I know you don't want to go with two 12's but have you thought about 1 15" the tempest from adire is awesome!

I got a 12" perfect (pushed by 300wrms) I'm happy, dosn't scream but does alright. The prices are coming down some, I see them on E-bay for around $110 or so. Good luck with your choice, if you pick from those two you should be happy. CC

well, shiva it is then i guess!! i was thinking the infinity subs because i had an interior theme going on there, as well as i LOVE their sound! i just wish i could hear a shiva before buying it... posted_image im not a fan of making decisions on the word of others, but this time i may need to.

If i were to get a Shiva, I would most likely be using a JBL amp, probably the bp300.1. what range of RMS power would be the best for this sub( i know it depends on enclosure and all but just in general) as the Adire site doesnt give much in the way of power handling specs.

The shiva can handle 650 watts, the power handling specs are on the website and they can be found at the following link: https://www.adireaudio.com/mobile_audio/drivers/shiva.htm

Although the sub can handle 650 watts it doesn't take that much to make it move, you might want to rethink your amp choice as this sub is dual 8 ohm. You need something that going to put out max power at 4 ohms. Something like this amp would fit the bill nicely: https://www.crutchfield.com/S-Y8DVNaObO5y/cgi-bin/ProdView.asp?s=0&c=3&g=110&I=235USB2150&o=p&a=1&cc=01&avf=Y, and it won't break the bank either. US Acoustics make good amps, especially for the money and I have used them before with great success.

375W per voice coil; 650W total to the driver
NOTE: Power rating is thermal only! It is NOT a power requirement; typically you get full output with significantly less power than the rating.

Taken directly from there site, Just an FYI

Have you ever heard a Shiva? I have heard both side by side and prefer the SQ of the shiva over the perfect. Also the perfect in no way, shape or form can compete with the shiva on bass. The shiva will go deeper, louder and cleaner.

well, i have made up my mind, im going to get the Shiva! now my only thing is im trying to find an amp. ksin reccomended the US acoustics amp, which makes 450 rms @4 ohms, but i may expand further down the road to 2 subs, in which case i will run the amp at 2 ohms. now im a little confused on this, as i would want about 3-400 watts rms for this driver, but when the amp makes say 300 watts rms@4 ohms, if i were to run it at 2 ohms, how would the drivers see the power? would it end up being 300 to both drivers or 150 to each driver.

my amp options are now as follows: the US acoustics amp mentioned above(450x1 rms), JBL bp600.1(300x1 rms), MTX thunder 342(340x1 rms). now i have heard great praise for the JBL amps, and i personally like the MTX amps as they have never failed me like some stupid Fosgate, and i know the US acoustics amp is a good entry level amp, but that is mostly what i have heard it used as. I am not necessarily an entry level application, and i have chosen these amps by price, features, and preference.

thanks,

Parker

If your gonna expand to two subs down the road then the JL BP600.1 is the way to go. You'll only get 300 watts out of it at the begining with the one sub since you'll be running it at 4 ohm but when you add the second sub and run both subs in parallel your ohm load will go down to 2 ohms and you'll get 600 watts out of the amp. As for your second question the subs will see 300 watts a piece.

ksin, no i havent had a chance to listen to the shiva... i wasnt saying anything against it i have just had good experiences with the perfects and enjoyed them, so i was recomendin them :)

JBL or MTX, both make good amps. I prefer JBL. US Acoustics is very good for the money, but really cannot compare to JBL. The Shiva is a great sub, you won't be sorry.

I'm interested in this same setup but I was wondering, would it be better to find a stronger amp for the one sub or just to run two subs at 300rms each? How well would this set up sound SQ and SPL? Obviously this isn't a SPL set up but how much bass would it have?

It will get plenty low and put out a lot of bass while still maintaining excellent SQ. You should be fine with 600 watts, it will get the job done.

Rock and roll, I guess it's time to break out the credit card.

Heres My opinion EIther ones grreat.

DONt get sony or volfenhag. or else haters in this forum will talk mad sh*t about your system.

remeber you only need to please your self.!

PEOPLE HERE THINK THAT your supposed to by top of the line brand and please other people. and they'll talk crap about your system check out the topic that i posted!

Do I get to vote on this, I like the Lear Jet XL12 and the Alpine 3503 amplifer for this setup. Dyohn might get this, maybe Teken and some others. I too would head in the direction of the Shiva and the JBL amp. I really want to take a JBL amp apart and see if they are building their own amp or if the circuit topology is much the same as any other made in Singakoreachinatiawanapore amp. There is just way too much who makes who in this industry.

Yea Rob, Lears are great if you can find them and can afford the price of admission. Didn't Lear invent the 8-track? JBL car audio amplifiers are, by the way, designed by Crown for Harmon International and assembled in the USA and in China. High-end and professional series amps in the US, lower-lines in Goundong. All JBL speakers are designed and assembled in the USA but use Chinese and (eghad!) Canadian components; alll Infinity (owned by the same company) speakers are assembled in China.

ok, so I built the box for my shiva that i will be ordering shortly, its a copy of one of the boxes from the Adire site, the 54 liter sealed enclosure. im guessing that this will be a sufficient enclosure to provide nice SQ at lower volume levels while still being able to play loud? i decided against the smaller sealed design because it would be maybe an inch wider than the sealed box im currently using for my rockford HE 10" sub, and im somewhat satisfied with the current setup, just looking for more as i dont feel the rockford is a great sq sub. im just wondering. it will be in a hatchback type application, and i will be able to build other boxes if im not satisfied, i was just looking for more opinions.

Parker

I'm not sure where you got that enclosure size from, but it is a little large for the Shiva. Are you looking at the home theater alignments? I would recomend around 34 liters for that sub in a car. Especially if you have a lot of power.

there was a .pdf file on the Adire site with examples of 3 different sealed enclosure applications for the shiva. i may have been looking at a home theater alighnment, so that could be it. would 54 liters be more conducive to a vented application? if so, i have always wanted to hear a vented box in my car. i do still have 3 sheets of mdf to build another box tho.
