audiobahn kicker ma infinity ? which one help!

[camaudio 10+ year member]

zane, you are majorly wrong, the ma audio line has only one authorized web dealer, they will not be found a t a flea market, and they certainly use the best materials, i have owned many subs(no infinity.s) and by far ma audio bashes them all including an LVS that had blown up, where the ma audio sub held true. next time do your research or get some experience before you bash other companies

ps Infinity subs are very nice sq subs

Im running 2 Audiobahn ALUM10x subs and pushing them with a Soundstream Lil Wonder 4 amp. They sound great and hit very hard. I have built a custom enclosure for my Trans Am. Each sub is in a sealed .8 cubic foot box. I have the subs bridged. Not to brag, but my system has hurt alot of peoples feelings, including someone that has 2 Kicker Solobaric 10's, (the square ones), he pushes them with a Kicker ZR600 amp. His are loud but mine have better sound quality and do not distort any. so hope ive helped ya.

Jeez, I am gone for a few days and look what I miss!

One Authorized Dealer huh?

These sites all claim to be web-authorized dealers:

http://www.carstereoconnection.com/MAAudio/index.cfm

http://www.outerlimitsaudio.com/directory.cfm?CategoryID=27

http://www.ddpproducts.20m.com/

Those to start- now how about availability? Look at these sites- the quality of a few alone is enough to bring question. All carry MA Audio, so where are these "select dealers?" seems as if any dealer who wants can get them.- again- just as mainstream.

Not so "select" are they?

As for flea-markets, I have been to two that have carried the MA Audio line- One is Homier Distributing, the other is Wholesale Merchandising. May also want to note a few pawn shops carrying New IN BOX MA Audio- Seigles Pawn, 1 st Avenue Pawn/Electronics, Granite City Pawn Shop and Collectibles, Mister Money USA.

As for the comparrison, it is odd that you offer MA Audio against Memphis' LVS model, considering the LVS is known to have several design flaws with its Backplate and Former, thus contributing to its poor performance. This was discoverd by Memphis and they accepted many returns of this model in favor of thier other products. Every company has thier share of bad products, however MA Audio (Mobile Authority, Anaba-etc) has had far too many to be considered credible or reliable without some skeptism/critisism from the dedicated audiophile.

Therefore, I find it strange that you would compare MA Audio to a woofer that has a known, and publicly admitted flaw, rather than to the Infinity Pefect itself.

I will admit, that yes- MA Audio is far superior to thier Mobile Authority Days, and they are heading in the right direction, however, they currently can not compare to the reliability, credibility, or proven successful track record of Infinity. Infinity is manufactured by Harmon-Kardon, a long time Industry Giant known for thier well designed products and impressive sound. Harmon has won numerous awards in both home and car audio industries.

I have had direct experience with both brands, MA and Infinity; The Infinity In my own car, and the MA in a few cars that I have installed in. It does not make logical sense to comment on a product without experience with it, so I will put that to rest right away also.

The Infinity Perfect 12.1 Easily took the upperhand in SQ and SPL output over the MA Audio MAW612. Each set of woofers was in thier reccomended sealed enclosure and fairly equally powered. The Infinity's from a Rockford Fosgate bd1000.1 and the MA's from a JBL BP1200.1. Crossover frequencies were set equally at 62Hz- an acceptable level for an SQ Vehicle.

The installs in both were designed primarily for SQ competition subject to IASCA guidlines and audible testing from the IASCA Competition Disc.

Both woofers handled the tests, however the MA left quite a bit to be lacking in the area's of Clear, detailed, accurate bass.

Also there was a substantial ammount of cone noise from the woofer causing undesired distortion and musical break up.

The MA's did hit hard, but lacked the musical characteristics needed for a decent sound.

The Infinity's on the other hand, did exceptionally well, not even strugling on the low excursion tests, or the tight punches on "Moon With the Rebel Base." -(which BTW- I have found to be an excellent reference recording for tuning systems- that and the THX sound Tests) Zero Distortion, total clarity and accurate response, and very hard hitting.

I even attempted to swap the amps arround to be sure that this was not amplifier induced. Even with this change, the Infinity's far surpassed the MA's.

Honestly, there was no real competition between the two, the difference was very much night and day with the Perfects comming out on top.

MA Audio Admitedly says that thier woofers are more so engineered for SPL applications, however, it seems that they have a little more research to do before they can keep up with the Infinity's on the overall.

Prior Installs that I have done useing MA amplifiers, have had nothing but disastrous results. Not a one of thier amps puts out anything close to what the ratings are- likely half the rating is more like it. Mabey some of thier amps were able to put out 4000 watts at 1 ohm- but at what current- and for how long? That is one thing that is very much neglected to be mentioned with thier ratings. Each amplifier of MA's that was installed either suffered from severe overheating, total lack of output, heavy noise, or general failure.

I make my recommendations soley based on my experience and available information. There for until MA can boost thier quality considerably, I can not reccomend to anyone a product with poor reliability, and known problems.

I would suggest that others here need to do a little more research also, before "bashing" other members of this forum. I would suggest starting by actually comparing these two brands side by side.

Take it easy,

i didnt ask you for an essay, but you fairly defended yourself(i didnt mean to bash)

sense my last post, i went out and bought 2 perfect 12.1D(very impressive looking and heavy) and continued to connect them exacly as i had my p12ils(ma audio) except at a different load to the amplifier beginning with parallel series(i used just about every method of connection). i then ran my version of testing, including some 303 infinity and Fear Factory. the infinity did good(excursion was weak) but the quality and imaging was there. Then came the real test. i rewired back to parallel stereo, put in my favorite bass cd(bass 305) and cranked it. not even a close to the volume of my ma's, the infinitys stop playing and i could hear scratching, so i took the sub out and the vc cam off the bottom of the cone, so i exchanged them, and the other 2 did the same thing(at the piont the store was pissed) so i got my money back.

as to ma audio, i have never had a single problem. i run my amp with a 4 ohm midbass to each channel, and a 1.5 ohm load bridged(i have no idea the total load of that) but its never even got warm, even in arizona where its 120 degrees out.

the subs sound very good for sq, and when i want, very good for spl.

i wasnt aware of the lvs problem.

as to the authorized dealers, only one

Please escuse me then if I question the results of your testing, as only sheer mis-use and clipping would have caused the the problems you are describing; which at best sound a bit far fetched. The Voice coil simply will not sever and come through the cone of a woofer-especially a woofer with an aluminum cone. The physical design and magnetic fields generated around the voice coil make this improbable as does the linear travel of the voice coil. If the coil goes beyond its peak travel, its windings will begin to unwind (decompress) which typically results in a woofer's loss of motion (travel) all together. This is something that happens internally, and again is generally ony achieved by abuse, clipping, or other mis-use. Now, if for a brief moment linear excursion goes beyond its peak and the woofers spider is severedfrom the cone, this can also produce cone detatchment from the spider- thus is also called over excursion, in which case the voice coil assembly would need replacement as well as the spider, and in some cases the cone. In a situation such as this, when the spider detaches( or over excursion occurs) the woofer cone moves freely for a moment which can cause cone distortion (damage), however, this is rare with proper installation and powering, such events will only occur again, by misuse.

As for the Infinity's falling short of the MA's, I would also like to know how you came to this conclusion. I ploted out the T/S Parameters of each speaker in its reccomended sealed enclosure and as you can see in the graph below, the Infinity Perfect- considerably out does the MA P12il.

If the Image does not load go to this link:

http://www.geocities.com/thunderbird302/WinISD.html?1009921755420

Infinity Perfect 12.1- Charted in Red

MA Audio P12il- Charted in Yellow

A near 10db difference between the two.

T/S parameters dont lie, clearly they prove the Perfect 12.1 is the better of the two in this situation.

Take it easy,

the coil did not go through the cone, it seperated. either the glue is inferior for the apllication, or poor construction(on all 4)

and i used the 12.1 and p12ils in the exact same box, 1.12 cubes sealed, and i dont care what a program said, i know the infinities have a better sensitivity, but the 12.1's maximum spl doesnt even touch that of a p12il
