JL Audio HD 600/4 Question...

MaverickNemesis · 01-21-2010, 01:43 AM

what im asking about the sws's under the seat would it be smart to cover them like the oem subs or just leave the uncovered?

quality_sound · 01-21-2010, 03:13 AM

Ohhhh, it's up to you . Unless you regularly put things under the seat that would damage them I wouldn't say it's a big deal. I saw one guy say he put them on to keep dust off (like a grill or some carpet would do that anyway) like that would hurt them.

I have the SWS under the seats and the Focal 100KRS in the front doors, and there is a pretty large "gap" in midbass for the reason stated earlier in the thread. OP, I strongly suggest you get dedicated midbass drivers for under the seats, like some Morel 9's or Hertz Space 8's, otherwise you will end up being sorry, especially for all the coinage you are dropping.

Also, bridging the JL HD600/4 into the earthquakes is a waste of this amp, since you will not even come close to putting that much power on the Earthquakes without frying them, and they would be more than fine with the 150W the JL amp produces in stereo.

How low are you crossing over your KRS100s?

I've got them at 175Hz right now.

Can't go lower than that? That's part of your problem. The SWS is just not good playing that high. Can you try closer to 120?

Well, I could, but it is a 4" mid after all...and the kind of midbass I am missing most is in the 80-100Hz region, no way any 4" can play that with authority.

+1 on the advice, I don't see how that can possibly sound good without a dedicated midbass driver, there is a ton of harmonic distortion up there with the SWS, not to mention localization messing up the soundstage.

MaverickNemesis · 01-22-2010, 01:15 AM

so focals in the front and rear with sws's under the seats will sound bad?

MaverickNemesis · 01-22-2010, 01:17 AM

well to add i like the jl amps cuz they are small and can be stacked while producing major power... they can virtually go unseen

whats the difference between the hertz space and the sws? arent the morel's 9"? I mean I already bought the SWS's but are not used...

That's what I've been telling you for a few days now.

The Space 8 and the Morel 9 are midbass drivers, not subs. They give up bottom octave performance to be able to play higher frequencies better so they can be used with smaller midrange drivers. The SWS is a sub. Even being an 8 it's still just a sub. You can't pretend it's not a sub just because it's small.

I'd sell the SWSs and get some Space8 or the Morel or Renaissance 9s.

how much do the space 8, morel and/pr renaissance go for? where can I buy them?

MaverickNemesis · 01-22-2010, 02:01 AM

also what amp would be good with the space 8's then since I see they are rated at 200 peak and 120 rms...

What I do know is that Morel Hybrid Ovation in the front, SWS-8 under the seats and the rest of the OEM Individual Audio speakers, all tuned by the bit one.1 and powered by 2 PDX amps, sound excellent to me and pretty much everybody that sits in my car...

You need to understand something: what I like in sound is not necessarily what you will like in sound, and viceversa. All the recommendations here are mostly based from people that have done several systems on their own and we pretty much know with specific detail what we like. We really do not know what you like. We can explain and recommend equipment, but you cannot be guided by digital selections (this will work, this won't work) when the issue is the reproduction of sound if you really have not done some physical trials on your own previously to determine for yourself if, for example, that elusive midbass that so many people keep saying that is not there at all is really not there, or it is simply that is not there in the level that particular tastes would like to be, but it is there.

Perhaps you can make the 4" driver punch some mid bass by adjusting the bit one in a way that by overlapping a region of the midbass EQ bands with the SWS-8 you create this very nice midbass punch for you. Actually, the bit one even help you do that with a real time bandwidth graph of the sum of two drivers responses based on your adjustments. Again, you have to do it to know how to do it.

Either install everything up and tune it with the bit one and see if you like it and learn by yourself, or if you can return what you bought and start over with something else then do so.

MaverickNemesis · 01-22-2010, 06:06 AM

well to be honest technic (thanks for the advice btw) I like vocals for the most part and to sound crisp and clean. I think I have enough bass with the L7, but now I feel like the L7 and the SWS's will overlap the 2 sets of focal k2's...

What OEM system do you have?

You could add the OEM Premium (Individual Audio) center speaker to your dash and get nicer front stage for vocals, but you will need one channel of the bit one to tune it.

whats the rms/peak for the morels? where can they be purchased? Are they better than the K2?

http://www.woofersetc.com/p4758/Hybr...ent-System.htm (I bought them used in this forum).

In paper, what I like about the Morel is that their frequency response is 60Hz-25KHz, compared with the 120Hz-22KHz of the KP. Although a 4" midbass punch cannot be compared with a 8" or even a 6.5" midbass punch, 60Hz is much better than 120Hz in a 4" when you are tuning these speakers in our cars.

I'm using a 80Hz at 24dB high pass filter with my Hybrids in the front in combination with a 175Hz at 36dB low pass filter with the SWS-8 using the bit one and there's enough midbass for me with that combo. I have tried several other cutoff (100Hz and 200Hz for example, all overlapping each other to avoid dips) combos but this one is the best sounding so far. But I'm not using a sub in the trunk either, so your results will vary once you get that L7 in the trunk. But you can adjust that with the bit one.

If you are in the mood of investigating a 4" component solution for your system, I would recommend that before you plunk almost $700 on a Morel set, or $500 in the KP just try this $128 MB Quart 5.25" component set: http://www.e90post.com/forums/showpo...90&postcount=9

Don't worry about their power handling, you can adjust their input level also with the bit one.

Hey, you never know if you end up liking them. If not, post them for sell here, I may buy them from you to test them as well.

quality_sound · 01-22-2010, 08:23 AM

Will a 5.25" mid fit?? I'd tossed around that idea but it didn't seem like there would even be enough area to mount it. Admittedly, I've only had the car for 3 days so I haven't had a chance to do anything with it.

Edit: Apparently some will. Interesting. Might be worth looking into.
