onkyo TX-607 help

[Mike P.]

The EP amp has a HPF at 30 hz. Are you building a sealed music sub?

[KrazyBassKevin]

Yeah the sub are already in a 3/4 in mdf sealed 2.5 cubic foot box

[Mike P.]

What are the parameters of the Kickers and what are your plans for the Fi Q that you're getting?

[KrazyBassKevin]

Heres the kickers

Model CVR12

Size (IN.,CM) 12, 30.5
Impedance (OHMS) 4 DVC
Max Rec Amplifier Power (WATTS PEAK/RMS)* 800/400
Sensitivity (dB 1w/1m) 86.7
Frequency Response (Hz) 25-500
Mounting Depth (IN.,CM) 6 5/16, 16.1
Mounting Cutout (IN.,CM) 11 1/8, 28.3
Min Rec Sealed Box Volume (CU. FT., Liters) 1, 28.3
Max Rec Sealed Box Volume (CU. FT., Liters) 4.6, 130
Min Rec Vented Box Volume (CU. Ft., Liters)** 1.75, 49.6
Max Rec Vented Box Volume (CU. Ft., Liters)** 2.25, 63.7

and this is what i would idealy like to use for the music and the woofer for my HT system

and for the FI Q the dual 2 ohm

Q18

DUAL 1 | DUAL 2

Fs: 24.5 Hz | 23.8 Hz
Re: 0.7 Ohms/coil | 1.4 Ohms/coil
Qms: 5.66 | 5.73
Qes: .64 | .63
Qts: .58 | .57
Mms: 322g | 342g
Cms: 0.13mm/N | 0.13mm/N
Sd: 1210cm^2 | 1210cm^2
Vas: 268 l | 268 l
Spl: 89.7dB 1W/1m | 89.4dB 1W/1m
Bl: 10.4 N/A | 15.1 N/A
Xmax: 27mm
Rms: 1000W
Sealed box: 4-8 cuft
Ported box: 6-10 cuft @ 28Hz
Sub OD: 18.500”
Cut ID: 16.750”
Mounting depth: 10.000”
Displacement: 0.24cuft

and the box i would like to replicate this one created by Dan

[Mike P.]

First things first. I found the parameters for the CVR12 DVC 4 ohm subs. Do you have them wired separately for a 2 ohm load or a 8 ohm load?

[KrazyBassKevin]

Currently i think 2 separate?...I was think about making a new box maybe tuned lower towards 35 32ish with dual 6 in ports (flares) in about 4-5 cubic feet also i would like this box to easily be modified to fi the 18 if possible or a box that could keep all 3 and when i rid of the kickers just board it and seal...The box i have is good and durable but the binding plates are garbage and the box it small.

Any ideas?

[Mike P.]

i think 2 separate?

Are the Kickers wired separately or are they wired together?

[KrazyBassKevin]

Currently separately cause u want to do 8 omh each channel on the ep4000 to be at around 550 watts each....

Hows that sounds...

Also i want to make a new box ideas anyone?...No sonotubes though

Cheers,

For music a Q of .7 is considered best. The sub will take 350 watts if the 30 hz HPF is used on the amp.

[KrazyBassKevin]

350 watts i was going to push 1450 ish through the q probably more and if i get a btl more like 2800!

but thats the future im trying to build a box and the system for what i currently own so thats the Kickers Mike what would be best for the kicker their 800watts peak i was wondering about running 550 to them on 8 omhs non bridged

[Mike P.]

i was wondering about running 550 to them on 8 omhs non bridged

For a music sub as shown in the model above they'll never take 550 watts. They'll bottom out long before that.

[KrazyBassKevin]

Well this is not only for music its for a HT sub as well and i was hopefully going to make a new box and 350 watts yes for blasting music that a lot and i wont have it at 100 anyways...gain come in affect there.

[KrazyBassKevin]

Any Box ideas yet guys? i saw some crazy ones in the DIY subs section....

[Mike P.]

Well this is not only for music its for a HT sub as well

You previously said the Kickers were for music and you were getting a Fi Q for HT. I'm lost.

[KrazyBassKevin]

Oh sorry no i dont have the q yet I have Kickers, but id like the box to be for music and HT.

And for the box to be easily modified to fit the Kickers and the Fi Q when I get it.

Sorry for the confusion guys

Cheers,

KrazyBassKevin

[Mike P.]

Here you go. 2 Kickers and 1 Fi Q18 D2. Both need a Hi-Pass filter at 18 hz. You'll need a port 8" diameter and 20" long. Not sure how the box can be "easily modified" to switch subs but I'm sure you'll figure it out.

[KrazyBassKevin]

Cool, great this is diagram show it from the Fi q sub in the box and then if the kicker were in ther with just them selves right?

and its quite simple if you normally make a 2nd face for the woofer have that with slots for 2 kickers 12 and the first face an 18 and both of the kicker magnets will fit ther and then when you remove that board put the sencond face for the fi q and then you get th box like which i can add a port too

and picture mike of boxs similar to the diagram one??


this is the box i was thinking of

Yup. The link isn't working for me. You can design your own cabinet so it has a net volume of 16 cu.ft.

[KrazyBassKevin]

sorry idk why it wasnt working here try this

http://www.hometheatershack.com/foru...m-x-build.html

[Mike P.]

That's only 6 cu.ft. not 16 cu.ft. Use the calculator link I posted to see how big the box you need is.

[KrazyBassKevin]

Your getting a box at 16cuft^3 with 1 FI Q???

OK Im now confusing my self Im so sorry,

here lets all imagine this is for 1 FI Q which plays mostly music like 98% and occasionally video games and for movies, i just dont see why i cant simply modify the Plans from
http://www.hometheatershack.com/foru...m-x-build.html
and use a FI Q 18 instead? i calculated it and i got aroud 6cuft^3 ????

CAn you help me, around 20cuft is way too big, idk where a number like that fits maybe with 3 or 4 FI Q's

But i just want a box like dan with a Q hopefully not to big, 6cuft^3 sounds about right

Sorry for the confusion thanks,
