:tup: corona which spacer did you get?

do you remember wat the inner diameter was on the spacers you made?

i see a lot of 6.5" spacers state: INTERNAL DIA. 5 3/4" OUTSIDE DIA. 7 1/4"

this is ok for these lanzar speakers? :confused:

Yes, the cutout diameter is 5 3/4" I made mine 7 1/4" outside as well.

Thanks! :tup:

I am sold. Now how can I make these babies work with the stupid Bose system? Should I get a new HU and new tweeters?

A good place to start is to look at Big's stickied thread on Bose.

anyone interested in replacing door speakers but....
 

I have read it. But your post below made me think you just found a short cut.

:tup:
Unfortunately, there are no shortcuts around the bose setup that I am aware of.

yah, honestly if you want to improve the bose setup, i'd get a new HU first and try to eq' it first, beemaz. make sure the HU has at least 4v pre outs. i have the shitty bose in my G35C and run a pioneer dd + got door polk components afterwards. sounds good. :tup:

Update on the speakers. RonRizz wasn't kidding, there is a lot of sound coming from these things. Was a little bit of a pain in the *** to mount them though, had to grind down my old spacers to make way for these beasts. That said, once everything was installed, the speakers sound great. In my scenario though, I need to add more sound deadening and perhaps get a thicker speaker mount, since I believe that I'm hitting the window frame at loud volume.

All that said, rep RonRizz for a great suggestion. For the price, these are the best speakers I've heard.

sounds good deusexq :tup: do you run anything else besides the speakers in your audio setup? ie HU, amp, etc.

Didn't buy the spacer yet. I was going to see what the audio shop had to install it. The amazon reviews on the spacers listed weren't confident inspiring. Has anyone used those for this instal?

Agreed, the reviews pretty much slammed it. Does anyone know if we can get by with a 15mm (~5/8") spacer?

This one gets some good feedback:
Amazon.com: Gino Vehicle Car Khaki 6.5" Wooden Speaker Spacers 15mm Depth 2 Pcs: Sports & Outdoors

I cant confirm or deny, but if the 5/8" doesn't give you enough, a layer or two of weatherstripping could only help matters. Personally, I use it under all my speaker flanges. It helps create a good seal, and helps with vibration issues. 1/8" is not much to make up. a single layer under your spacer, and under your speaker flange may be just the ticket.

Thanks. I may go that route instead.

@RonRizz

You mention Xover at 50 hertz, I assume that's highpass and active, what order of cutoff were you using at 50 hertz?

Were you using another active filter, routing to the passive module for the Hertz, or simply relying on natural rolloff? If you were using a passive filter, was the impedance of Hertz and Lanzar about the same?

Thanks

I am running fully active off the processor in my head unit.
I am bandpassing my hertz woofers at 63hz with a 6db slope, to 1600hz with a 12db slope, and when I change to the Lanzars, I'm dropping to 50hz, and a 12db slope, to 1600hz with a 12db slope..... I run 2 sets of tweeters, the first are band passed from 1600 to 12khz, with a 12db slope, the second set in my a pillars are high passed at 12khz, with a 12 db slope.

Interesting, you're getting pretty low response from your tweeters, the 1600 hz @ 12 dB high pass (in your dash?) is lower than I might have expected - what kind of tweeters are you running (assume this is in the dash location?)

The tweeters are in the doors, just above the woofers, and they are the set that came with the hertz hsk 165xl component set. the others are in my a pillars just a touch above ear level. You can see them in my photo album.

Ehhh… Is there a pop quiz next week on this? :eekdance:

I respect you guys who can speak to this audio magic. Haha I just know how to use the + / - on the HU. Match a few color wires to make it work on the back end. :icon17:

My blown ear drums will appreciate this less no matter how tempting it is to demolish the stock "upgraded" Bose that I have. Looking at the side by side shot, there is no comparison. Nice call to share it with us. Gosh I miss my old gear.

Its not as complicated as it sounds.... Briefly put, (or as brief as I can make it) Human hearing is 20 hertz to 20k hertz. There are 10 "octaves" therein. (frequencies) To move up the scale one full Octave is to double the frequency. so your octaves would be 20, 40, 80, 160 hertz, and so on... up to 20,000.
Component speakers are designed so the proper frequencies make it to the proper speakers. They do this with crossover networks, or "filters"
Low pass filters leave frequencies below their point through to the speaker
High pass filters leave frequencies above their point through to the speaker
So in a typical setup, A Subwoofer will see 20 to 80 hertz. A low pass filter keeps anything over 80 hertz from getting to the Sub.
A Midrange will use both a high and a low pass filter. 80 hertz high pass, and 3200 hertz low pass. This means the Midrange will see frequencies from 80 to 3200 hertz. A tweeter will get a high pass filter at 3200 hertz, so it only sees frequencies at 3200 hertz and above, to 20k Hertz.

So in this setup, my crossover points are......80 Hertz, and 3200 hertz.
A crossover "slope" is the number of decibels a filter will allow to pass for every octave beyond that set point. they are typically at 12 decibels per octave. for example, lets say you are playing some music at 100 decibels. because your Subwoofers Low pass crossover (filter) is set at 80 hertz, your subwoofer will see frequencies above that, but at a greatly diminished amount. (in this case 12 db per octave) so your next octave is 160 hertz......100db minus 12db=88db, next would be 320hz.....88db minus 12db=76db....easy peasy.
Realize that a difference of 3db in volume is much bigger than you think.

You are a god Ron. :bowrofl:

All I read is blah blah blah sound... Blah blah blah speaker.... Blah blah blah subwoofer... Blah blah blah tweeter... Blah blah blah crossover lol

I will be honest, I had to read this several times to understand the mechanics. I was getting lost in the numbers (ironically have a degree in engineering, lol). But I think I get it now. Obviously not to the level of mastery you have but it makes sense. I appreciate you taking the time. I saved this to my iPhone notepad for future reference, lol. :tiphat:

I am still sitting on those speakers… Need to figure out where to get them installed. Too lazy to do it myself. After doing the HU, I had my fill of electronics/wires. What should I expect to see a shop charge? Just to have an idea of whether or not they are priced fair.

Thanks for the run down Mr Ron you have been repped. I get it as I have some back ground in music so it make sense to me.

I'm going to have mine installed at shop in Vegas, $75 is what he quoted!

$75 is not a bad price, Obviously they will differ with location. In my area, going rate would be around $50

Hey ron, thanks for posting about these speakers, Im gonna pick up a set too.. Upgrading my speakers has been on my "to do" list for a very long time. Thanks bro.

Just purchased a set of these speakers and spacers.. Im a little excited. :icon17:

:tup:enjoy....

Getting mine installed tomorrow :D

thank you sir.

Doing the install yourself or shop? Let us now how the install goes. Mine are still sitting in the box, lol. Need to buy those spacers.

So the shop does not want to install them unless I have an amp that can push these bad boys. I don't want to argue with them as they want me to get the most out of the system and I'm ok with that. So I need recommendation on a good 4 way amp.

Really? You still have the stock HU?

Nope, it's a Pioneer navigation HU...from about 2010 or 11.

Is this the same exact speaker? Found these from another website that doesn't charge for shipping or tax. I think I'll buy them here and save an extra few bucks.

Lanzar® OPTI6PM - 6" Opti Pro Series 400W Midrange Speaker

If you're only trying to amp these 2 speakers, you only need a 2 channel amp. Are you trying to do subwoofers too?

Those and tweets...

Yeah, I guess you do need a 4 channel amp.
