What 8" midbass speakers?

LT4 Hawk 9 · Post by **LT4 Hawk 9** » Fri Nov 12, 2010 6:50 am

Anybody got a good recommendation for a reasonable cost? I'm running them off of a JL 450.4 amplifier's 150w/ch side. I was looking at the JL ZR-800's.

Anyone have experience with these?

i know there is a set of nice orion xtr 8"nib on ebay for about $250 a good deal IMO. i know there are a couple of guys here that have used them

I have used the earthquake sws shallow 8? in my E90 bmw they were great i used them off rear channel of a x100.4 they had very nice output small vented or sealed box.. I could not ask for more I did a group buy with some other guy on the bmw forum so it was about 180 us plus shipping for the pair

Thanks for the replies! Ideally, I'd like to stay under the $200 mark if possible. I've got enough tied up in this thing as it is.

For sure, I'd like to be able to use the boxes I built for the quarts, since I had to hack my floorboards up to get them set in there. They are PVC caps, and are not very big at all.

Sadly those enclosures are probably way too small to get the full amount of midbass out of any speaker. They will roll of at least 10-20Hz higher than with a large enclosure or "infinite baffle" setup.

I'm sure of that, but they are recessed into my floors like this:

And I can't go any larger. wider hits the frame rail, taller hits the body mount, deeper and the tire hits it when off-road. It is what it is, and I can't do anything about it. I'd love to have a half a cubic foot box in there, but I gotta live with sub 100% SQ and have a vehicle that will work right when I'm done.

What about infinite baffle in that case? Cut some holes in the enclosure so it vents to the air outside of the car, yet still has a bit of protection from the elements.

I would at least suggest an aperiodic membrane with such of a small enclosure.

You could try this and let us know how it works out. I was looking at these for my doors...

That would be a pretty good compromise!

an aperiodic vent would most likely help relieve some of the pressure and also keep outside dirt and dust out of the speaker. but may get clogged with dirt from time to time so you may have to take the speaker out ever so often to blow the dirt out with an air hose.

DIYMA is large fans of these for midbass woofers.

not enough room for kicks? the starter or high/low swithc(what ever that is) is held on by two screws and could be moved over which would cause much less damage then cutting an 8 inch hole

can't believe no one as has suggested the ti9s....

LT4 Hawk 9 · Post by **LT4 Hawk 9** » Fri Nov 12, 2010 1:27 pm

Thanks for all the replies!

There are vents in the kick panels, and I need those to breathe in the summer since I have no A/C. The dimmer switch would sure be easy to me over, but with that come another problem: As mentioned above, the rocker panel is a "C" channel, and the legs of the "C" come in far enough to just miss the enclosure as it is. I can't really make it larger in any dimension without getting REALLY creative.

I'll likely get a pair of either the Quarts linked above, or the Daytons. They are both priced where I want them to be, but the Quarts higher power rating has me leaning that direction so far.

how loud do you like your music? While it has been a while since I have installed a pair, every pair of quarts I ever installed for someone that liked their music loud was disappointed mainly in the midbass. Quarts sound great at a good normal listening level, like they do in sq competitions which is where they made their name but when you crank them they just always left us wanting more from them.

I have a set myself....
I saw that auction before...it's essentially only one IDQ8...the other needs a recone, which is no longer available to my knowledge (my set was one of the last).

I want to be able to crank it up when I have the desire.

The Quarts I have now were freebies from a friend, and have been laying around for a while after being pulled from an old install of his. I ran them for a few days until one blew, and now I need something to replace them. These seemed to have enough output to sounds really well at the level that I listen plus some, but evidently something stupid happened or it wouldn't have failed.
