Going sealed, the Image Dynamics ID8 comes to mind. I liked the sound of mine (2 sealed in an '08 Escape on 500WRMS for the pair). I'd like to try out the IDQ8.

Just checked out the ID8. Seems nice. I'll let him know about them. Thanks

What about a Tang Band W8-740P?

Proper box volume is about .18 ft3 for a Qtc of .7

 

[MrFoca]

How good are they ? Could not find the specs on it. Maybe cause I'm on my phone.

BTW, I tried to link to the driver I suggested but the page opens "blank". Why??

Try parts-express.com and search for W8-740P

Little smaller of a box, he has a spot where he is building a box. It's tiny,maybe .25 tops lol. But them ID8 could be used In .20 it says.

Was also reading about the Alpine type R 8. says they can be used in small enclosures.

for an 8" isn't .25ft3 pretty small, i have 6.5's CDT m6+ and it calls for .45ft3

i guess u could go with more Height than depth for an 8" in huh

for small boxes like that are u planning on just making ur own and also what mdf are u going to use 5/8" or 3/4"

It's not for me, Getting info for a friends build. I told him due to the lack of airspace. He might want to use a 6.5 inch woofer. I believe it's being made out of .5 MDF.

CDT QES-820 has a sealed enclosure recommended volume of 0.3 cubes, including woofer displacement. It's expensive, but it will work well in this application.

No, I mean .18 ft3.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Makes for a Qtc of .707 and a F3 of 66Hz. Should be a very good match for most vehicles after considering 12dB/octave cabin gain below 70Hz or so.

Totally depends on the T-S parameters.
