Ugrage from a IDQ10v3 to?

[rjay]

While I love the sq of this sub I feel sometimes it can't handle some of the bass heavy songs at a higher volume or that it won't be able to handle it in the long run without damage. So I was thinking of trying a different 10 sub, just wondering what would be a good upgrade while atleast keeping the same sq of my IDQ. Working with 500 watts to a 2 ohm load, but what ever the sub is I need it to be able to perform decent in a sealed box as I am trying to save trunk space. Box I have now is about .75 cu ft but could prob go up to 1.2 or so if the new sub needed. Don't mind trying a ported box if it could be built small enough. The space I'm allowing to be taken out of my trunk is 20L x 14D x 17H. So what subs would be a good choice? Here are a few I was thinking of: JL 10w6v2, SSA Gcon 10, or ID Max 10 and any others you can think of? Thanks

Can't think of anything that will sound as good AND get louder. The GCons look good but haven't ran one myself.
I'd hate to say it but I'd try out a W6
Or see if someone could make you a small enough ported box for the idq

Yes, try porting the idq, use aero port to save some space.

IDMAX is essentially an IDQ that's capable of handling more power, but I would suggest trying it ported. My ID10 really opened up once I went ported and it plays pretty darn flat. Just have to make a small EQ tweak right at its tuning frequency and she shines.

Here is some ported enclosure specs from id

20L x 14D x 17H = 2.07 Cubic Feet internally, lots to work with there!

Cool, I don't know alot about ported enclosures. Actually I've never ran one myself in the many years I've had systems! Thanks for the responses, I kind of figured since I would be using the same amount of power I may not gain anything switching out subs. I will get with rabbit and see what he can come up with. Thanks

No problem mann, pro rabbit would take care of you.

Why are you worried about cranking your subwoofer? Just follow the procedure to set the amplifier gain properly. It should handle the rated power daily. I suggest using a -5dB test tone instead of 0dB though. (most music hardly ever reaches even -5dB)

I think it's very hard to work around the laws of physics if you're not going to change much in your setup. If you go with 10 sealed, sensitivity will be about the same (IDQ already has above average sensitivity). Cone area, about the same. A subwoofer suited for a bigger box may reach lower bass slightly better, but that's that. Amplifier, the same. So I don't see how you're going to see any improvement in SPL. If you want a louder 10 inch sub for a sealed box, ID IDMAX10 or JL W7 could be a good choice, but you need a lot more power and considering the money spent on that setup, you may still end wondering "so where did my money go?"


First of all, have you considered using the IDQ in a ported box? My understanding IDQ subs are sort of universal, having good performance in either type of box, and the box probably is not that big, although I haven't seen a models for IDQ10v3.


Next, I would suggest to take a look a setup with a ported box and a couple of 8s. Take two Alpine Type-R 8s in a ported box. Don't read too much into their price, these subwoofers are considered very good for sound quality. There is a loong R8 thread on DIYMA. The standard recipe is to put two in a 1.1cu ft ported box (net) tuned as low as possible. Most tune at around 30-35Hz. Basically use the biggest port length you can fit in the space. Each piece handles about 300-400 watts, but 250 a piece should still be good, specially in a ported box. One R8 in a ported box should already sound about as loud as a 10 in sealed while reaching deep bass a little better. And here is another interesting setup for the lazy. One Peerless XXLS10 in a 1 to 1.3cu ft net ported box. The reason I say for the lazy is because you could basically buy a 1.2-1.4cu ft sealed box, stuff it with polyfill and insert a flared vent for tuning frequency of abot 30Hz. WinISD predicts very manageable vent length. Frequency response looks smooth in WinISD without peaks and F3 at mid 30Hz. 500watt amp would be great for this, but this subwoofer has 4ohm impedance beware. You probably need to add a subsonic filter set at about 20Hz or higher when you have a ported setup tuned at 30Hz or higher.

Yeah I am going to try a ported enclosure for my IDQ. When I had the volume at the loudest I would listen to it, on some of the bass notes the sub sounded like it was trying to bottom out or something, guess it went over it excursion limit (I don't know how to explaine it)? I know I could just turn the volume down a little when that happens, but figured a beefier sub may be the answer so I wouldn't have to!

Are you sure it's bottoming out? It's very hard to hear a subwoofer bottoming out in a sealed box. It takes a lot of power to get the excursion past the linear xmax of 18mm, much less past the physical limit. Maybe you're over-driving the amplifier, clip the signal, and that's why it does this.
