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

hold on man sheesh your trying to throw money at a problem that can be solved with tuning. first thing i would do is TURN THE BASS OFF! then reset hu ( flatten everything) turn all processing off. then reset the xovers on amp and hu pop a cd in with some nice vocals on it and start adjusting you hpf( both on amp and hu) for the comps till they sound as good as you can get them with the xovers . then do the same thing with the subs. but make sure your amps gains are set properly first !then simply play with eq on deck till you got the best sound you can get. sounds to me like your tuning is just way off .

He does not want to lower the bass to solve the problem. Assuming everything is max'd out and the vocals cannot keep up with the bass his only solution (since he wont lower the bass to match the vocals) is to increase the vocals.

Dude - bridge your amp if it is not already. You are wasting half the power of the amp if you are not, and power will potentially get your more volume from your comps. If the tweeters overpower the mids to you, attentuate the tweets with the setting on your mb crossover.

Do not worry about injuring your tweeters from too much power. They have protection circuitry built in to protect them. They either have the lightbulb that absorbs excess energy or the thermal protection that cuts them out when they get too hot. I forget which protection your specific model has. You also have ears to listen if they are distorting.

If this does not work, find louder comps or you must add more speakers to achieve what you want. It IS possible your 2 12's are just too loud for one set of 2-way comps to keep up with at full blast.

I would not recommend going active as a solution to this problem. But if you insist, all of those crossovers will work. You don't really need the 3-way crossovers but you could cross over your sub too if you wanted. I assume your sub amp cross works fine as is. My choice would be the 24xs. It is cheaper than the digitals and has the nice 24 dB slopes.

i wasnt asking him to turn it down forever just to turn it off for the sake of tuning the comps properly.

I think the problem is your lack of knowledge involving component systems and tuning. Its not a bad thing. You just need to read up some and figure out the problem.

The tweets are louder up high. I like the way they sound there...The vocals are also louder with them up near the windshield.

My bad, I thought you were looking for improved SQ (which would fix your problem properly), not simply more noise coming from your high-end. =P

There's no reason to play your system so loud unless you've already killed your hearing (foolish) or you are in a db contest (with hearing protection hopefully).

Let's not forget Bostons are 3 ohm speakers.

thanks for all the input guys... I think this is a big part of the problem though. I really wish there was a place around here that had a scope so I could actually see what happens when I try out all this stuff. With a 3 way system, dont you have 1. the midbass woofer, 2. the vocal (looks like a big tweeter), then the tweet itself? I almost got the 3 way q-line system at the show. They were selling the model from 2 years ago for 55 bucks!!, but there was no warranty, and if they werent loud enough...thats 55 out the door...and even that is to much for me to waste...but that was a great deal...I almost went back and got a few just to sell.

as for the amp...its only bridgeable at 4 ohms with 1 channel, or 2 ohms by 4 channels I believe. I posted the link above, or on page 4 of all the specs on the amp.

can you wire a component set to 1 channel? if not...why not. I dont care about my fade and balance.

and when I got tomorrow to maxxsonics, and he tells me that A. They just cant keep up, or B, I need a new amp...I think im going to sell everything and start from scratch...this is just to frusterating from me. Ill take a few months off and save up...whatever I can since as of next thrus. I will be un=employed until i get a new job.

As i mentioned in an earlier post, you COULD indeed wire them to a single channel, if it's 2 ohm stable. But you would not lose fade, you'd lose STEREO (left/right channels? nope! just one!)

Wow, this thread is wild and wacky.

Maybe I missed it, but what is your x-over point between your comps and your subs?
