[QUOTE="T3mpest, post: 6830388, member: 560148"] not that will play midbass as well, no. To get high effeciency, as in 100db/1w/1m you need a very light amount of moving mass. Light mass means high fs so the driver rolls off sooner, also you need a very short coil, so low xmax as a result. If you want your fronts to be able to play down to 80hz at least, you'll want 5-8mm of xmax and on a 8inch mid your pretty much not going to get over 96db/1w/1m. However, you do get more powerhandling with a mid than you do a small compression driver that actually fits into a car. The mids I'm upgrading to from the xs mids are BMS NS515's. They are 96db/1w/1m with 5mm of xmax. That's basically the ID drivers, but at leaste 4db's more sensative, possibly 7, IDK how ID rates their mids. 1 watt at 4 ohms is 2 at 8.... Anyway the mids I have now can handle 200 watts continously. AES ratings on pro audio mids are no joke, that's actual power that won't break it on music. A single mid is 96db/1w/1m, even with a few decibels of power compression a single driver with 200 watts will gain another 20db's due to power increasing from 1 watt to 200. that's already 116db's, plus 6 more for the second driver. 122's at 1m, a car is usually less than 3 feet away so maybe 124ish? If you need more than 124db's of continous output, your either deaf or you will be VERY soon. Most concerts are 110-120db's depending how far out you are, mid crowd is still low 120's so your well over even LOUD rock concert volume. Anyway you can get midrange in an 8 that will be 100db/1w/1m, but they won't play any lower than 300hz as xmax will only be maybe 2mm to keep the moving mass low enough to keep effeciency high, so then you'll need to do a 3 way setup and still won't get 100db/1w/1m midbasses lol, unless you can fit 12 or 15inch mids somewhere.... How much do you want to spend on midbass drivers and what sizes and I can help you too lol. There are alot of good pro audio midbasses out there at any price range. The mids I'm using are easily among the best for my application and cost 300.25 shipped to my door. I got my xs mids from a team member at ID for 250 IIRC. For a headunit I'm using an alpine w200 and a alpine h701 for processing. Very nice combo as it's very easy to use and i have a double din slot in my car stock. Once I get rid of my AI-net and get my optical cable hooked up my noise issues should be gone. Honeslty, the noise floor in my car is good, I'm just anal, you can't hear it with music, just when you mute it and turn it up. Also the focal disks can expose it due to their VERY dynamic nature and low recorded volume level, I've never heard it on normal music though. You said you want to use your stock door location, any idea how much depth that gives you? PA mids can be kinda deep sometimes. My subs are Acoustic Elegance AV15's. Very nice subs. I chose them because they modelled very well ported when it came to integrating when you include cabin gain in pretty small enclosures, about 2.5-3 cubes net. Also they have a stupidly low inductance and can play very high. That's nice with pro audio mids since you get a dimished low end slightly due the higher effeciency. Plus, if your into high effeciency you probably like your music to be loud, so running your mids low is NEVER good from a sq perspective, especially in a 2-way. [/QUOTE]
