I would like to make a request. These are mid bass 6 1/2" driver's from parts express that are $6ea. From the hundreds of reviews lots of people seem to like em. Here are the specs. I have them in my doors for temporary replacements and they kick ass! Here's the link and specs.

Good news, it looks like the drivers tab in BassBox Pro is working again. I bet it fixed itself during one of the Windows 10 updates. If it stays that way then I should be able to find the time to run some more models over the next few weeks. More to come and sorry for the long delay. Its been a crazy year for me.

Thanks for the update and for everything you're doing man. Looking forward to it.

I bought my SB Acoustics door speakers based on the information in this thread and they’re fantastic. Thanks for your work.

 

[SWRocket]

@JCsAudio Thanks again for doing all this!
I'm trying to learn how to model MB drivers myself and hoping you can shed some light on methodology; Specifically, I'm wondering if you model in sealed enclosure and if so how large and what Ql value do you think should be used to model the leaky door?

Hey I'm looking for budget bangers for a friend. In what way do these "kick ass"? Are you using them in a 3 way configuration?

For the price of them and what they can do, they are definitely worth it. I am actually running them 2 way passive unfortunately at the moment. They actually are real punchy and you will definitely need to sound treat the doors. They lack a bit of depth but I'm sure with some EQ they can sound even better. They sound really good compared to entry level driver's to some brands. If you are in a extreme tight budget I will definitely buy these.

 

[Selkec]

Where is all the info? Am I overlooking it ? All I mostly see is 7 pages of people asking to model this or that but haven’t seen much real info? Can y’all put it all together in one post?

 

[Bikey]

Is this BassBox Pro modeling any different than WinISD? It is neat to see the graphs but WinISD is free and it takes all of 2 minutes (per driver) to input the T/S data so the program can model the responses.

Next up is the Silver Flute W17RC38 which was a very popular home audio driver used in car audio in the early DIYMA days. This driver is not designed for car audio and is intended for use as a mid-woofer in a two-way system and can be used for a three way too. It has an fs of 37.5 Hz and a very low Qts of .24 and is not suited for IB, yet it does do ok in the model on 70 watts. This driver does not have a shorting ring and looking at the inductance it is on the higher side at .53 mH. The price on this driver is low and runs around $32.60 currently for a one speaker on Madisound. This driver uses a unique wool fiber paper cone and a simple motor and it has a cast aluminum frame. The wool cone helps to damp unwanted cone breakup making it behave well in a two-way setup. These woofers also run on the large side and are deep so take your measurements carefully. These will also need a rain guard to keep their coils and fragile paper cone protected from the elements. Silver Flute W17RC38-04 ohm 6-1/2" Wool Cone (madisoundspeakerstore.com)

Silver Flute (Green) vs AF GS60 (orange) vs AF GB60 (Yellow) on 70 watts

Excursion for this driver is actually decent considering its not designed for IB use but you will need an HP filter at 80 Hz if you use it infinite baffle in a door.

I have (4) silverflute 6.5's in my car and i can attest that they do sound really good especially considering price.

 

[Mike-G]

Recently found this thread and enjoyed going through it. Are there going to be any more updates? I would like to see the SI TM65 MKIV, The CDT HD-6 or ES-06, or maybe even Hertz ML1800.3.

 

[JCsAudio]

Yes Mike, I need a little reminder every now and then. Just been so busy lately and the program has given me trouble with Windows. Let me see if I can getbsome more updates up between today and the upcoming weekend.

 

[JCsAudio]

I didn't forget, just very busy. Give me some more time.

I can jump in here too. I installed these in the doors of my wife's sequoia to replace the old rotten JBL 7" woofers.

The $6 specials are GREAT in this application. They sound great and have surprising ability to play low. I have them high passed at 40Hz, 12db and they play nice and loud.

I'm glad you also like them!! I actually swapped them out for the Dayton Audio DC160-8 6-1/2" Classic Woofer at $29.98ea. The Dayton sound a bit more dynamic than the $6 specials. I may put the $6 Woofers on my rear doors for my rear fill. I love the $6 specials and I will recommend them to everyone. It's just Im looking for a smoother response and from the graph of those Dayton I mentioned is what made me put them on and I'm not disappointed.

ext up is the is the Peerless SLS 830667 8 inch driver from Madisound. This driver is not made for car audio but with proper rain guard could work out well because of its friendly IB TS parameters. It has an fs of 42 Hz and a total Q of .66. The price on this driver is low at $55.52 each. This could be a good budget option for a three way system.

only if your door is intended for 8" install from the factory.
Though there are other speakers that better work as midbass like PRV audio 8mb450-4 v2.This thing can get insanely loud (115db until it hits excursion limits at 80Hz according to WinISD) comapred to SLS's 107 db max. The downside is that it requires a little bit of compenstation by parametric EQ to remove the results of bass gain due to Qts > 0.7.
The problem with that 8" SLS is that in WinISD 6.5" Hertz C165 L performs in 80+ Hz area almost the same without any issues with creating pods, modyfying the door cart etc. So bigger is not always better, especially if you have a car with factory place for 6.5" midbass speaker.

 

[eugene.vasyuk]

Another good woofer to model:
Ground Zero GZRK 165SQ (120Euro/pair)

I tried to do it via WinISD and it gives 2db higher max spl compared to 8" Peerless SLS and is easier to drive by the amp

Next up is the SB17MFC35-04 Poly Cone Driver. This driver is not made for car audio use but with proper rain guard could be used as a mid woofer for both a two way and even a three way system. It has an fs of 31Hz and a Qts of .29 so it is not really suited for IB use. The price on this driver is low at just $60 each, which makes this driver a budget friendly driver considering the advanced motor with shorting ring and nice Poly cone you get. I used the Egyptian papyrus cone version of this driver and it was one of the best sounding budget drivers I have used with a nice clean mid range sound.

Cone excursion is not bad and should be ok if you keep the power in check and use a HP filter at 80 Hz LR4. As you can see in the graph it is right inline with the AF GS60 shown in light blue.

View attachment 294801

Wow, so I currently run the NVX version of the SB 6.5, what advantage would the GB's give me based on these curves? Is it just cone control/power handling below 100hz or so? I might be mis-understanding the implications of these curves.

 

[winkychevelle]

Guess my doors are sealed enough that they don't exactly act like ib anymore asine haven't bottomed out yet. my silverflutes are on 90w normally crossed at 50hz 24db slope but I have run them with no high pass at all on some rock style music to fill in the bottom end a little.

At one point they were on 125w crossed the same.

Honestly this little $35 speaker is damn good for the money. It struggles beyond 2500hz though. Which mine are crossed at 2khz lowpass anyway.
