Does anyone know of a 2ohm SQ 6.5 comp set. SQ being the key.

Most component set out in the market are design to run at 4 ohm. The only component set that comes to my mind that runs lower than 4 ohm is Boston. They have a 3 ohm impedance. If you are looking to get a 2 ohm SQ component set. Why not wire up two set of 4 ohm component set to serve that purpose.

Keep in mind that the impendence of a component set doesn’t determined the sound quality of the speaker, but rather the design, the material being used and the engineering behind the speaker does.

Is your goal just to get more power out of your amplifier?

2 ohms is really the best impedance for components anyways, because the damping factor on the amp goes down which = the amp dosn't have as much control of the drivers movement (saying it in a very loose statement).

Yes I am looking for more power but sound quality also.

Go with CDT, MB Quart, Focal, diamond audio..adire audio Koda to name a few. Each have there own sound. I suggest listening to them before you buy.

If you want SQ don't shoot for low ohms. Why do you want 2-ohms?

ID makes a 2 ohm set, but as stated before this screws with the damping factor of the amp. Ideally an 8 ohm set on a 2 ohm amp would be great, but 4 ohm is most common and acceptable.

The best way to do this is to choose a good quality set of components (such as those already suggested or any others) and purchase an amp to match their RMS power handling capability. NEVER try to run components in parallel just to achieve a 2-ohm load if you care about how it sounds. This is foolish. Get the proper amp.

DYohn,

"NEVER try to run components in parallel just to achieve a 2-ohm load if you care about how it sounds."

I have never experiment with kind of set up before. I always thought if you have good equipment the deterioration of the sound quality from 4 ohm to 2 ohm cannot be that drastic. Can it? After all, with good component set also cames along with good engineer build amplifier. Your technical input on this is much appreciated.

Yes, it can be very drastic in the upper frequencies, but it depends on the amp. In subs you can easily get away with running more noise in your amp because it largely happens out of the audible range or above the crossover frequency. But for your mains, the noise generated by cutting the impedence in half often occurs right around 1500 Hz, the heart of the midrange, and up around 16KHz, the top of the high end, which can make the sound very shrill and harsh. Also an amp may be 2-ohm stereo stable, but that does not mean it will perform anywhere near its S/N or THD ratings at 2-ohms. Even some of the best amps fall into the terrible noise range below 4-ohms net load.

all the bad things about amplifiers double (or come close to doubling) when you halve the impedance... noise is twice what it would be, distortion is twice what it should be, heat is twice what it should be, damping factor is half what it could be, efficiency is considerably lower... If you are concerned about SQ, then DO NOT LOOK FOR LOW IMPEDANCE COMPONENTS! Stop it, or I'm gonna have DYohn slap you hands... posted_image

Ideally, you should find components that match the output specs of the amp. Me, I really AM concerned about SQ, so I run my 550wpc (at 4 ohms) into and 8 ohm mid-bass (which, I know only nets me somewhere in the vicinity of 275 wpc, but I'm running *6-inch* mid-bass drivers, for cripes sake!) The DF is amazing, the transient response is as well, the amp NEVER gets hot, the distortion is vanishingly low... all the good things in life. I also run the Eclipse DA7232 STEREO amp into a single DVC Titanium 12 (at 4 ohms per coil and 1300 wpc) in a 1 cube sealed enclosure, and I defy anybody to tell me that I am doing so... if I hadn't just told you I am doing that, you'd never know it.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Go haemphyst! around every corner someone's trying to bridge amps into 1 ohm loads and run .5 ohms stereo from any amp they can find! Where has this trend spawned from?

I run 4 ohms on all my amp channels. Like You, I oversize my amps and turn the gains down. Headroom for days! I want to post this as a banner "SQ" means Sound Quality and Not Sound Quanity".

Right on. The trend toward lower impedence loads is because people have been sold on "lower ohms = more power = louder from the same amp". Now while this is true (within the limitations of the gear) what they don't understand is the also true fact that "lower ohms = more heat and noise + more current draw from alternator = shorter amp life + easier to clip = really poor sound and bad choice."

I really, really cringe and want to strangle people who say "I want it louder" (and who are NOT SPL competitors!) and who really don't care about anything else. Fine, use Sony and Pyramid and Pyle and Volfenhag equipment and by all means run it at 0.3 ohms and crank that gain up, baby! My company need to make a few more sales after you blow your gear up (and your ears out.)

Oh and by the way, my sub runs at 8 ohms. Everything else is 4...

Well I run a US Amps USA-200 on my comps which are 2 ohm and I don't have any audible distortion or "looseness". A good comp set that run's at 2 ohm are the Image Dynamics CXS6 2 ohms, I have the horns comp set that comes with the same mid's and I love em.
