First of all, you can check out my install thread herehttps://www.diymobileaudio.com/forum/...ad.php?t=19541
As you can see the system consists of
-Panasonic Head unit,
-Infinity Reference 4ch Amplifier
-Alpine Mono MRP-M850
-DIYMA Reference 12"
-MB Quart QSD
As the title insists, the review will be on QSD 216 Components.
Let me first tell you guys that I am no expert by any means, and this review will be very subjective based on my limited experience. English is my second language as well, so please excuse my grammar and lack of vocabulary.
- I know there are several debate regarding the quality of MB Quart Tweeters.
But Let me say it here clearly, the Q Series tweeters are NOT harsh when used properly. This tweeter is by far the sweetest tweeter I have heard. However, these tweeters are only as good as the installer/tuner. Where you put these tweeters greatly influences how they sound.
Putting them On Axis as you would with soft dome tweeters? Big No No.
These tweeters need to be Mounted Far off axis. When installed correctly, these tweeters will give you the top end extension like no other. In terms of crossing them over, I have it crossed it over at 3.25k with 12db slope.
Passive crossover cuts it off at 2.4k with 18db, but I do think that it is maybe lil too low for these tweeters. In terms of eq, i noticed slight spike at or around 4khts which could be associated with what people call harsh. But no trouble here though, bit of Eqing fixes the problem. I think these tweeters do what they are supposed to do the best, that is playing the cymbals etc. I would personally cross it over even higher if I have an ability to run three way active. Bottom line here is install them Far off axis on pillars, cross them over bit higher, and you are good to go.
By no means, these midranges are midbass monsters like scan or the new premier component. I have mine crossed over at 70hts. Yet, the midbass is snappy and tight. Not a bad performer at all. In terms of midrange, they are fair. Maybe it is because I mounted them in my doors, but they do sound lil bit colored. Bit of clever EQing could definitely help here. But I am terrible with EQ. haha
However, in terms of detail, they do perform quite well.
Bottom Line? they are fair midbass performer with good detail in midrange(bit colored).
The system as a whole,
-The system images quite well. Expecially the tweeters. The imaging from tweeter is dead on without any TA. I believe putting them off axis on Pillars helped here alot. The midranges needed TA from RF 360.2, but can't complain here since I mounted my midranges in doors. As a whole, the stage is quite high. They do extend fairly far away as well. Depending on recording here, but the voice extends farther than my windshield with certain songs. As for upfront bass, as long as I am not playing a rap song with over boosted 40htz, it does give me up front bass. I can definitely appreciate nice recordings here. To sum it up, I think the QSD components are fair choice for the going price these days. Running them active can really bring out the potential, and it is only as good as YOU are!!!! so have fun experimenting and tuning because it does have the ability to give you a rewarding sound!
Here is how I would rate these speakers.
Value: 8.5 considering the current going prices.
