Profile Variations Tuning Session 09/04/09

The tuning session for the first batch of profile variations for the KD-S100 has begun!!!

Today, we will be using the Studio A control room at Avalon Recording Studio for reference. This studio was designed by Tony Bongiovi using the same acoustic treatment as his legendary Powerstation Studio. Our claims that the DPS technology brings recording studio sound quality into your vehicle is not a marketing gimmick. We literally tune our vehicle profiles to reproduce the sound quality of professional recording studios!

I will be updating our progress in this thread, and we will be updating our twitter feed at http://twitter.com/Bongiovi_DPS throughout the day.

Really cool that you guys are doing this. I just installed this HU in my 1988 Porsche 944 Turbo and
It sounds good . The Porsche has very limited space for speakers and being the Tweak head that I am I'm really looking forward to trying out some new profiles.
Thanks again

Thanks for the feedback. I'm happy to hear that you're enjoying your KD-S100.

Thanks for the follow up on the phone earlier. I am very impressed with amount of effort Bongiovi Acoustics is putting into this project. I am very glad I chose the head unit I did.

To everyone keeping tabs on our tuning session today...



We've come up with a few variations on the Universal Profile during this and previous tuning sessions and we want to know what you think! They will be posted in the near future to the website at http://www.bongioviacoustics.com/kds100beta but for those who want them today just send me a private message from this forum with your name and email address and I will be happy to send the new profiles to you. There are three new Variations for cars that have standard speaker configurations (including aftermarket speakers) and two subwoofer specific profiles. More about the new profiles soon...


Joe

Outstanding
Thanks for all your work
PM sent

I'll be sending out emails with the profiles package for the rest of today only. After that you will have to wait until they are online at the website. Give us your thoughts when you get them!

I just installed DPS VAR 01 and it really did improve the sound in my car.
Seemed to give it more defined bass, less muddy and more powerful also the highs are
not as harsh. I went back and forth between this profile and the original and
it is better.
thanks a lot Guys, I really appreciate your hard work. I look forward to
future revs.
Thanks again

OK, tested out two profiles.

I first loaded in Var 01 since I have a regular cab truck. It sounded better than the universal profile. The highs were not as harsh and ear piercing. It also seemed to help some with the staging in the truck. With the universal profile it seemed like most the sound was behind me, however, this profile seemed to bring it back up towards the front of the vehicle some. Great profile for bring down the highs and clearing up the mid range but still did little for my subs.

The second profile I tried was Var Sub 02. It was better than the universal profile hands down. It seemed to not sound as good with my subs as Var 01 till I tweaked the crossover on my amp some. Then it was great sounding with the crisper bass from my subs not quite as muddy as before. The highs were still a little high in my opinion, but adjusting the treble helped with this.

I have a question with the sub output and the crossover that the radio has would it be ok to turn the crossover on my amp to full and not low pass? The reason I ask is the lpf adjustment on my amp is an analog knob and seems to be touchy at times. Still want to test Var Sub 01 but need to give my ears a break for a little while. I know you will say turn it down but it just sounds so good.

Thanks in advance for any help and replies.

I would thing that it will be fine to put your subs on full range. We did our tests with the sub set to 150Hz which is pretty high for a sub. We designed the SUB profiles so that no crossover is required. By decreasing the low frequencies going to the main speakers, much more power is available. We made sure that the low mids are taken care of so that there is no "disconnect" between the sub and your main speakers. The total output of your system should now be much higher! Hope this helps...
Joe

p.s. You just gotta know we crank it when we're driving home

Tried the amp on full range and it sounded better, however, my remote bass boost does not work with it on full. I like using it since my Sirius has a lot more bass than required. Lets me tone the bass down for satellite radio and back up for cd's. Anyways looks like I will leave the amp on lpf and just turn the crossover up so the head units crossover is below that of the amps.

I would like to thank all the people involved. This is really awesome that you guys are doing all of this. I have never seen a company or group of guys put this much work into a product.

Today I made a two hour trip to the in laws. I have been happy with this unit up until today. On the way there I was really able to listen to several different types of music. Older rock seemed to be almost spot on in terms of sound, however, the rest seemed to be lacking a lot of mid range and bass. With my old head unit it still had a lot of mid range and bass without the subs on. I hate to bring in the generic EQ profiles as a reference but the system currently sounds more like the generic pop eq profile that was on my older radio. However, I tended to prefer the rock eq profile on my older radio. Anyways, I am not trying to complain too much just wondering if I can do anything to bring the mids and bass back for my 6.5 components in the front. Oddly enough the 4x6s in the b pillars are making it seem like the band is behind me rather than in front or middle of the vehicle. When I try to fade the sound to the front it throws everything off and just is not right. Am I doing something wrong maybe?

Hmmm interesting. Are they aftermarket speakers all around or just in the front? Also, what profile did you have loaded while on the trip? And you have 12s in the back right?

The front speakers are Sony 6.5 with Pyle Wave tweeters wired in parallel. The rear are bazooka 4x6 . Yes, I have two cadence mallet 12's in the back but have the crossover set to 125hz. The profiles that I have used today are the DPS Var Sub 02 and DPS Var 01. The subs provide plenty of low bass but the other speakers seem to be only producing higher frequencies and not blending with the subs. The issue with the staging being focused to the rear does not bother me as much as the sound just being off. The reason I purchased a new head unit was that my previous one quite playing cd's. However, the previous one sounded fairly good with the speakers I currently have, even though the front and rear are of different brands. I appreciate your help and am willing to try what ever you suggest.

I realize the Sony speakers don't have any good reviews but they were in the truck when it was purchased. They stayed because they actually sounded pretty good with the previous head unit. Later I added the tweeters wired in parallel and mounted next to the mirrors to bring the staging up a little. It all worked out fairly well and sounded amazingly good for what it was.

The reason for this post I to try to minimize laughing at my setup.

I think I have officially hijacked this thread, Sorry.

I am now satisfied with the sound of my system and am confused as to why??? The only profile I had not tried was DPS Var 03. Being as desperate as I was to get my system to sound good I tried this profile. The difference was night and day for me. It sounds freaking awesome compared what it did on the trip with Var 01 and Sub 02. Now explain to me how a profile for a large vehicle sounds best out of all the profiles in my regular cab truck?

Awesome!

And you've made a point better than I ever could!

The whole idea with the Universal Profiles is that ANY one of them should work. Music is very subjective and it is our goal with this program to cover a wide range of situations. I'm really glad VAR 03 is working out! VAR 03 is one that I created on Friday during our live tuning session. I had larger vehicles in mind but I also wanted to address systems with loud tweeters in that profile.

The biggest factor in your system's complexity is the aftermarket speakers. Every speaker model out there has vastly different characteristics and this, coupled with your vehicle's interior acoustics and road noise, changes how the DPS interacts with your system. No speaker is "perfect" so it doesn't matter what the brand or price point is. If you like it, then its good!

I suppose the point really is that the descriptions included in the readme are just "guidelines". If you aren't quite satisfied with your sound yet, try another!

Keep up the good posts 'yall!
Joe

So when are these new profiles going to be released? I can't wait to try them out!

I think a good part of it was the that I have loud tweeters. They were drowning out all the other parts of the music.

Well
Your review of Var03 made me want to try it out in my car.
I think I like it better also.
The real test will be on the road. My car had tons of tire noise (I'll be glad when
the potenz's need replacing)

Var 03 is by far the best in my truck. The only thing that is off sound wise is the staging, however, I don't think that much can be done about it easily.

awilson40: Good Luck with finding the right on for you. Took me several days to get the right variation and my amp tuned to where it all meshed together nicely.
