I'm personally running a set. Feeding them about 125w each, and they get moving like crazy. Hell, they have as much xmax as some subs. Low end is great, pretty much as good as it gets for a mid. Top end isn't the best IMO, for me it gets a little nasty too far past 2.5khz. All this is gonna be install dependent too.

Well talked to a tech guy at Image Dynaimcs today, and he gave me some recommendations on some specs to look for when choosing a midbass driver. Of course he told me that the IDQ 8 would b perfect for these, but unfortunatly I can't find them anywhere.
Here r the specs he told me to look for:
Q: .3 - .5 (the lower n the range the better)
FS: mid 30 - 60
efficency: 88db (4ohm), 90 - 92 (8ohm)
He also told me to look for a paper or poly cone. So I'm still looking, a lot of these 8ohm drivers that I have looked at have an efficency of 86-89db. So with a low efficency and a low RMS, I'm probably gonna have to look for other options.
I have found these Peerless PPB 830868 8"...they're on Madisound, but currently not availible. They also have a higher RMS than most of the 8ohm drivers I have looked at (120w). Also I looked at the Seas P21RF/P (H511). So let me know what you think about these guys...

Would this b enough to EQ my frontstage?

I have a Kenwood ddx-7015, and if this would handle the tuning for my horns and possibly midbass, i think this would look really good where the little drawer is n my 4th gen dash. Only thing is that its 4v preouts, but so does my HU.

phl is more than efficient enough, how does 100db/watt/m sound? PHL 2520. They are a bit pricey i think about 350-400 for a pair, but just about the best 8inch mid you'll find to mate with horns.

if you are going to spend 300 on that, go for the zapco sp4. it is the best EQ for the money. dont let the 4 band scare you away, it is better than the arc 7 band that i had in my truck before that.

//content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif please explain how 4bands are better than 7 bands for tuning? both units not true parametrics, both quasiparametrics with set q values.....

dont get but hurt cause i said that my 4 band is better than my old 7 band arc. the arc had very little mid range, and mid bass was non existant. the change from the arc PEQ to the SP4 was 10 fold.

Oh lawds
Aw crap if thought they were unavailable for some reason, or I woulda gotten them instead of the xxx mids. 99 shipped, **** good deal. Oh well:furious:
Sounds like tuning differences to me.
Frankly, I'm with 3.5max.
7 > 4

mid bass/ mid range is where i noticed the 7 band lacking. right off the bat, with the amplifier exactly the same, i noticed a huge difference. the only thing i noticed that was up to par on the 7 band was the highs.

I'm sorry to call you out on it again...but you dont sound very smart simply by throwing big names around- your logic is not the type of which those companies would benefit from representing them as a consumer base. Its not whether the Zap 4 band is a good Eq or not, its your logic on how you describe that it is 'better' than a 7 band in how your midbass sounds (both Eq's in question have
close thd levels/ signal to noise) Any differences you'd hear would be responsible via YOUR tuning.
... With 4 bands OF COURSE YOU ARE
GOING TO GET A BIGGER AUDIBLE BOOST when you tune one band because that band covers a greater range of frequencies as opposed to a 7band - which covers a smaller area and allows more precise tuning of the frequencies that NEED tuning.
The real difference you are noting is through perception-(because apparently that is how
a newb like you judges something) . Your boost of the center freq of 125hz on a unit like that affects way into to midrange being the next band is at 1khz
The problem with an Parametric (in this case quasi-parametric)
4 bands is that it affects frequencies that MAY NOT need tuning whatsoever- resulting in poorly tuned system.
The purpose of an EQ is to tune....
more bands ->more precise tuning-> better
(Of course your real purpose anytime you get a chance is to say that a Zap product is better than an Arc one....) I say you are full of shyt, and your posts lately confirm it.
So to get back to the topic sorta, has anyone tried those 8 inch Ushers? Ive been tossing around the idea of getting those for like 3 months, but dont want to dish out the money for them and end up with something Im not real pleased with. Of course they look so cool to me thats about enough to make me buy them //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
Ive really been thinkin about a pair for awhile though. Ill probably be all bumbed out when I find out for sure I cant fit 8's in my doors. My 6.5's were a bish to get in there. Hopefully theres more room in there than I think there is.

do you ********** to arc's ads or what dude? throwing out big words, is that something you made up to make yourself sound better or smarter or something. its a simple fact that the arc KEQ and PEQ lack in mid range and mid bass. everyone i know of that has gone with either of those EQ's has been unhappy with them, including myself. hours of testing obviously dont make up for the extensive catalog learned knowledge that you have.
