Just installed my MB Quart QSC 216's...REVIEW

[snb778 5,000+ posts]

Well, I just installed them about an hour ago at work. Here is my review...

They have a very nice sharp sound like I like, and the hi's get very loud.

I have them wired to an Alpine F545 which the birthsheet read 165x4@4. I have them wired at 4 ohms, and the gain is on .8 out of 4.0 (lower the # on the gain, higher the volume)

The midbass isnt to great, i had to turn the bass gain on my head unit up a good amount to even get good sound out of the midbass, but I really dont care to much about it. Im more of a fan of just loud vocals and sharp hi's. it seems like most of the vocals are coming from the tweet though...is this normal...i thought most vocal came through mids. Another thing is the tweeters didnt come with a tweeter mount where it gives a little angle for a top dash mount as you will see in the pics. I just had to face them up at the window...which is fine since they are so sharp.

Well I can say I get 1/2 here. The vocals just dont seem to keep up with the bass still!! I have to say im pretty disappointed, because besides that I love the way they sound.

The HP filter is on crossover is wired to -3db. Crossover is set to 80 Hz.

I might put them up for sale later tonight if I cant fix this problem, and give the Boston Pro's a try. //content.invisioncic.com/y282845/emoticons/crying.gif.ec0ebefe590df0251476573bc49e46d8.gif this sucks.

I wouldn't give up just yet...too many factors that need to be addressed. How did you set your gain? It sound's like it's cranked.

Those speakers sound way better if they are not pointed right at you. I also wouldn't put a metal dome next to the windshied like that....too much reflection and comb filtering going on. Also try an attenuate the tweet to -6db and see what happens.

Did you have them bi-amped with the 545? Maybe try that to control the tweeter level better. Also try lowering the HP to 60,63 Hz and see if that brings the bass up front more.

Make some corrections and just listen to them without the subs playing. Try just the tweeter and then just the mid and see if you can get both set up properly. It's taken me week or months until I've settled on a mounting location for my tweeters.

See i dont have a problem with the midbass right now...unless they are really really good mids that give a ton of midbass, i could live with the crossover at 120..like they were with my type R comps, so thats fine where its at. The Tweets I love. I love loud sharp sound, so i dont have a problem with that either....its just the vocals really... The mids are pointed right at me in the kick...but they are what seem to be slacking....

No they are not bi-amped. they are just wired direct.

and yes...the gain is like 3 setting away from cranked...its at .8 and goes down to .2 i believe. I could wire them to 2 ohms, but then thats rated 250x4...actually probably around 275x4...and the speakers are rated at 80-150...so I think they should be fine at 4 ohms...no?

I have heard the Boston pros and i loved them...but it was in a car with no bass really, so I have nothing to compare it with....When i was tuning it, they sounded loud...i thought they would be fine, but I started bumpin Paul Wall "internet goin nuts" and the lyrics were gettin drowned out pretty well.

I wouldn't wire a set of components in parallel to get more power to them. Bridge your amp instead and turn the gain all the way down....it's not a volume knob!! What is the preout votage on your HU???

Turn the bass down!! If you set your system up correctly, you shouldn't hear your bass....it should be part of the music. Swithing to Boston Pro's isn't going to solve your problems.

Thats what I meant...but they are going to be seeing around 225-250...which is probably to much

Im thinking about upgrading my 2 12's now to 2 15's..I love bass...its the main part of my system...its why I love car audio...BUT, I also like to hear the music...I want my front stage now...to be able to shine with these 2 12's..more less 15's...and I thought these speakers would do that with no problem.

Its like if my front stage was overpowering the subs (not to loud, just overpowering)...people would say turn the bass up....I want to turn the mids/vocals up...or upgrade...but as far as MB-Q goes...there is no more...this is the most they got.

SO with out turning the bass down, i want to resolve this problem. You really think wiring them to 2 ohms wont be to much power?

Mess around with them for awhile, if you can't get them right, I have plenty of Cheap Top of the Line Boston Speakers, I need to get rid of //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

You need MORE speakers to keep up with your bass tastes. It doesnt sound to me any which component set can just do it for you. Forget aboutr SQ or staging for that matter, something tells me its not your thing anyways.

Sounds to me like all you need to do is lower the gain on the sub amp and raise the VOLUME. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

See, when I had MORE speakers...everyone told me I dont need that many in the first place...everyyyyyyyyyone told me I just need a better pair...Now I have them...a MUCH better pair...and im still having problems.

and im not turning down the bass... There are plenty of people out there that have systems as loud as mine, and louder, who have front stage speakers that keep up with their bass. Anyone have a 145-150db daily system that has a good sounding front stage???????????????

I somehow have to figure out how to turn up the mids/vocals.....I think if i had a 5 channel amp and a center channel speaker that would definitely solve the problem, but to do that I need a new amp, and a new head unit...which im completely not ready to do. Im worried what Im going to need when I upgrage my subs to 15's....then the way I look at it now...im screwed...

what kind do you have?

 

[Starky 10+ year member]

Boston z6's and Boston Pro 6.4...stick a couple 400 watts on either of those bad boys and you got one loudass system

 

[snb778 5,000+ posts]

are the 6.4's the pro60's? and whats the diff in the pros 60's and the z6's?? been trying to figure that out.

 

[Starky 10+ year member]

Z6's are Bostons Top of the Line Speakers...im pretty sure The 6.4 Were Bostons top of the line Speakers a few years back (until the 6.5 (though only cosmetically different) and Z6's came out)....both have Amazing Sound Quality, both Very Crystal clear and sharp

Boston Pro 60's

Boston Z6's

 

[snb778 5,000+ posts]

ahhh, so they are both comp sets... my amp is only 250x4@2 ohms so I dont think I could power the Z6's from what everyone says...even though they are rated from 40-400 watts..hahah...but the pro60's say rms is 125....I dont see how people are throwing 300 watts on those.

I just really need to hear them...but I dont want to use these MBQ's to long if im going to sell them...thats my big problem now.

 

[Starky 10+ year member]

what is that amp Bridged? and dont forget these speakers are 3ohm
