Looking for 6.5 midbasses in dual 2ohm or single 1ohm load....any exist?

pretty sure resko1 can build mids, i vaguely remember him telling me about some he built

i took another look at my pods....if i can find someone skilled with a router i can widen the opening on the pods to fit 8in //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif i think that'll be the better route for me

I posted a story on DIYMA about those old PPIs. You're not Mexican are you (search for that post...it's a crazy story)What's your system as-is and what are your goals?

system is as listed in the sig, minus the ax400's I was running for the fronts. One ran the tweets and midrange, the other bridged 4ohm per side to the Illusion mids. My DLS IR3's only go down so low. on the 12db bandpass they're set around 600hz ish to keep the low end of that midrange from distorting. The illusions can play up to that point and sound pretty **** good, but i also have them crossed at 125hz on the hpf. they'll still play down to 80hz pretty well at full volume and sound great, just not crazy midbass on the lower end.

I plan on getting an ax606.2 in there, and now the midbass channels will do full power (200wrm) at 1 ohm stereo. I'd reallly like to have the midbasses stereo and not mono.

Im also curious why a 1ohm impedance is necessary for a front stage driver, especially midbass. At some point you simply should go to an array of speakers, as it provides some benefits over trying to pump a lot of wattage through a single driver.

At first I tuned the amp to do about 100wrm per side to the illusions in thier pods...but i guess being int he pods they need more powe to shine. MUCH to my suprise with the ax400 workin full tilt the illusions really shined. I was impressed by how not only the output, but the coil not getting too hot.

you run midbass 80Hz-500Hz?
i run midbass 50Hz - 160Hz, and i use a shallow slope for the HPF to get as much low end information up front to keep bass in my soundstage. works great. requires a helluva good install though.

many subwoofers have too much inductance to be much good over 200Hz. It's a case-by-case basis.

that CDT woofer seems like it may work for you (provided i has the freq. response you want).

i emailed the cdt person, there wa a typo and it's only a single or dual 4ohm driver....no dual 2ohm.

im pretty stuck with what to di with the DLS IR3's.....they are only rated to go down to 500hz.....

i recall hearing that about the subs, they wont sound well on the high end. god damnit.

those orions look tempting //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

so your going to get some 8s?

Anyways, an accumatch will smoke those. I would not recommend Accumatches on regulated amps and even some unregulated. An old Fosgate or HCCA? Different story...

Anyways, here's the link for the Orion mids; Orion HCCA6 woofers Brand New!!! Warranty ads a/d/s/ | eBay

I have a/d/s mids from the same seller. Those are 2ohm woofers and are pretty much the same thing as the a/d/s woofer except the impedance. I'll vouch for these having more midbass than Focals, Dyns, and pretty much anything short of a dedicated subwoofer. I have 5.25" a/d/s mids that out performed Focal K2P's back in the day - I a-b tested them in my car and on a soundboard...no comparison. Those mids are ugly, but for $125 they're pretty killer.

As far as rebuilding a 6" mid...I'm sure it's possible but I wouldn't bother. Why do you need that low of an impedance? Were you thinking of running a bunch in series b/c if you were, 16ohm raw drivers have become more popular as vintage tube enthusiasts really like them.

What's your system as-is and what are your goals?

ehhh..... on the fence about it. im pretty sure 8's wont go above 200-250hz without sounding like hell.....unless there's a miracle 8in out there that'll play high enough, i might be stuck with 2ohm 6.5's.....

 

[audioholic 5,000+ posts]

IDQ 8's play well above 250hz, and people have even successfully run them 2-way with CD2 horns. Good luck finding them these days, I doubt I'll ever sell mine. But Ive heard the CDX 6x9's from ID perform similarly. Im sure there are others out there these days too. Playing above 250hz is easy, Im talking about 1khz (or more). You also have options like large displacement 6.5's like xxx's that move almost as much air as a decent 8. But your impedance requirement is what is holding you back, not the frequency response you want. Perhaps a new amplifier is really what you should be considering here, not 1ohm mids that have great midbass and great upper freq response. Simplify your solution.

I heard some German Maestro 8" 2-way comps yesterday in a sound board (sealed enclosure). they sounded pretty good. the 6.5" comp set was better in the upper midrange (as expected).

they have JL ZR800-CW on closeout for like $160 each which are 8" that are rated up to 500Hz.

but these are all 4 ohm drivers, so you'd need a better amp.

im pretty sure i found a buyer for my illusions, and i want to give those hcca6's a try. if im not happy with the orions then i'll continue to search for something else. perhaps 100w rms on the beefy orions will do the trick. id love to run a pair of xxx 6.5's, but im affraid 100w rms wont be enough for them.

 

[cd6551 10+ year member]

With 100 rms on tap for the xxx's, especially in a sealed pod, I really don't think you'll get the output you're looking for. I will say that when you keep the xxx crossed pretty low that they will pound and sound pretty **** good. I think thats your best bet to keep up with that 4hp beast

 

[BassAddictJ 5,000+ posts]

pretty set on the 2 ohm orion hcca6....good price, 2 ohm, old school, should hopefully do well off 100wrms in the pods. if not then ill be a sad panda back on the market.

 

[i2ain2thunder 10+ year member]

my suggestion would be multiple 4ohm svc midbass drivers, that way they'll handle more power and get to a 1ohm load.

no space for that....not right now at least //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

adequate space for multiple midbass drivers is difficult in general and usually they are implemented poorly. in addition, you have to be careful with their frequency response so you don't encounter comb filtering, and the locations for multiples result in drivers closer to the passengers.

I have some slim Morel 8"ers you might be interested in...if you don't mind an 8ohm coil.
