Contour Enthusiasts Group Archives Forums Modifications Audio Rear Deck free-air Sub question.

There are a few large xmax 8" drivers. Mine is a Dayton Thruster . Partsexpress also has a few Hi-Vi (expensive) drivers with 8.xxmm xmax. I'm sure Dave knows more off the top of his head.

I can't get all the T/S specs for those Audiobahns, but they look good so far. 30oz magnet. high sensativety.

Yes dnewma04 mentioned these Dayton drivers to me once before. Wow a double recommendation. SO there must be some truth to their performance.

Well, it would seem that he hasn't mounted his from the top of the deck and I suspect he would have the same results. So where is his experience with top mounting, i don't remember reading it in his posts. I don't doubt that his deck rattled, what I question is your explanation, or his reasoning why it would rattle less when top mounted. He may have a perfectly logical explanation.



Aaron's deck had already been deadened when I heard it so I can't comment on the rattling. My stance is that by cover 1/4 of the outside radius of a driver's radiating area, it will not affect the output, or induce excessive rattling in the deck.



The best thing I could recommend would be to try to seal the door to the best of your abilities and get a high quality driver. I can honestly recommend the dash mount because of the complexity of the install and the digital time alignment that would be necessary to get an accurate musical image. The cost would be intolerably expensive. 2Deep2's car has a couple of Seas excel magnesium coned 8" mids in his kick panels that seem to do the job pretty well.

How much money would you like to spend to get good midbass? Are you in search of competition quality?

I guess we have to define what you consider to be a lots of bass. Opinions differ on this subject. If you are just looking for a small amount of filler bass than a 6.5 may be able to provide it. Do you have a reference that we can shoot for when making recommendations?

I am looking for drop in performance only though hidden forms do interest me. Would sound deadening a door completely not just the cutout area but the total surface of the door really improve the bass output of a driver significantly to make the cost of purchasing and applying the sound damping material worth the effort? I do not believe in a deadly silent cabin for there is the need to hear the outside world to keep one from sleeping on those long drives or from being alerting by an approaching vehicle.

When I get a chance to try to fit the enclosure I built to make sure it works, I can give you dimensions of the enclosure if you want to build one. Or if you wanted me to, I could build you a box and send it to you for a minimal cost (compared to a q-logic enclosure) but you may need to brace your rear deck and dampen it.

As far as the door goes, no matter how well you sound deaden your car, contours have too much wind noise to allow you to fall asleep. Unless you are narcoleptic like me. If I were going to prepare a door for minimal cost, I would completely line both the outer door skin and the inner door skin with dynamat.

The only time that I ever experienced really impact bass was back in college when a professor loaned his bass horn to an outside fun raising concert where in which I stood in front of the horn which was about 12 feet by 12 feet honest and boy did I feel those bass drum hits and those bass guitar notes.

Can that be had in a car? Of course not for there is just not enough air space for proper wave propagation. To answer your question about how much bass I have to say I just want some more that I am currently getting now from my two pioneers tsp682 in front and two pioneers tsp6895 in the rear and one audionbanh adm60 in the rear deck.

There are cars that are reaching upper 170 dB range. You can most definitely have that in a car. In fact, the transfer function makes it much more likely than it is outdoors. It really doesn't take much to reach 140 dB in a car whereas at a concert it would be difficult to reach those levels.

You do not understand what I mean by impact from the silence of birds chirping to the thunderous wave of a bass note cannot be had in a small space. Been to a live orchestra concert lately. Go and you will see what I mean.

I know exactly what you mean. I haven't been to the DSO in about 8 months, unfortunately. I wholeheartedly disagree with you, it can be had in a small space.
