Image dynamics id 8

[Ridinhi 5,000+ posts]

Hey guys, tried many setups in my single cab and some worked better than others. I finally got my front stage sounding pretty satisfying (to my ears).
So, I want to switch it up as far as bass. I want to try a sealed setup with quad 6.5’ or 8’s behind seats. Id8 comes to mind. Any thoughts on if they would work well and if they would sound ok? Not looking for something like a ported setup will give. Just want some good sounding bass that would get decently loud to blend well with my front stage.
frint stage consist of infinity kappa perfect mids and xovers paired with cdt drt26 tweets. Amp is nvx vad 8402
Power for subs is ct sounds 2000.1
Any input is appreciated even if it’s to tell me it’s a dumb idea.

I'd look at sundown sd4 8s they were made specifically for sealed boxes

I’ve had ID’s and IDQ’s back in the day. Never liked the low end output on those subs (lacking) and output overall wasn’t my cup of tea. They are clean and tight so it comes down to what kind of bass you like imo. With the power you have be careful which I’m sure you already know.

My next sq setup will be 4 savard hi-q 6m5s in 2.5 at 34hz at least that's the plan for the moment. A natural f3 of 29.8hz and a normalized f3 of26hz with cabin gain should do me fine plan is ssf at 25hz and lpf at 63hz may bump the hpf up to 70hz depending on if the 60hz null ends up showing up.

The id8s I'm sure sound great, the old green basket ones did, but the only sub I'd consider in a sealed enslosure other than the sundown sd-sd4 is a stereo integrity hst but those only come in 12 and 15.

Thought about these but didn’t want to spend that much. Guess I should have state my budget. ~100 per sub is what I’m looking for. So around $500 total

Gotcha. I could wire my amp to 2 ohms for less power.

If I could find a deal on some sd3’s id go for them. They are slightly less mounting depth than the sd4( I think so). Space is crucial behind the seats. Also, would .5 mdf work verses .75?

I have used .5 pine ply in the past but I added a few .75 cross braces to stiffin up the large panels.

Lots of people have used 1inch dowel rod as well.

And yea the sd4 8 is a bit deeper. Look on Facebook marketplace you might find some for a deal but at $100/sub or less I don't know how much performance you will get.

Gotcha. And like I said, I am not expecting output of a ported enclosure. Just something to blend in with my front stage. And being having 4 subs (although sealed), should make enough bass. I hope,lol

Another thought guys, I would go ported because these subs would allow for a small enclosure and fit behind my seat. Ct sounds meso 6.5’s. I could do four in 1cube net. According to tc sounds. I chat with them to confirm this because if the small box but they said that is what they recommend.

How much mounting depth do you have and total cubic feet?

2 cubes total and maybe 6” depth

2 cubes net that is

2 cubes net would be perfect for 4 6.5s with 2 3inch aeros.

You could also do 2 8s in the same space or even 1 12 ported

Guess I was wanting to do sealed because of my available air space.
although Ct sounds suggest a cube for 4 meso 6.5’s, you think that is too small?
I could do more space but not behinds my seats. Don’t want to use any space between my seats for The reason that I will prob build a center console and incorporate armrest.

Alright guys, the Dayton audio um8 has caught my eye. Once I get home I’ll measure and make sure I’ve enough clearance and if so, they may be what I go with.

Personally I think .25 is too small. .35-.45 would likely be were I went. At even push to .5per if possible. But that said I'd model them all in a box program first since some subs do act funny.

My dd506 we're in .5 each 1.15gross for 2 of them. Technically that box was supposed to be too big but the 300w subs took 750 each for nearly a year before being sold in as new condition

Almost all quad 6.5 setups I’ve seen where in 2 cubes.

Sealed with a net of 2 cubes, most 8’s will work perfectly fine in .5 cubes each (running 4 of them). If you knock it down to two 8’s, ported is an option as well. That mounting depth is gonna be the biggest factor on what to go with imo.

Exactly! Let me ask you guys, those meso 6.5’s have a low xmax like 8/9mm. How much of a factor is that as far as loudness. I understand xmax but not sure if it won’t matter as much since I would be running 4 subs.
