SB acoustics makes great drivers on a budget. Might be at the top end of your numbers, but well worth it.

These do look nice, but the woofers are a little bit out of budget and I'm also a bit concerned about the low qts. I'll probably deaden, but won't fully seal the doors. From what I understand, it's better to have a high qts for the situation I'm putting them in, yes?

If you wanna just pull it of a box qnd have it sound good.
Grab these. They are the nicest sounding 100 dollar ish set I've heard in a while.

Yes, I'm definitely considering an out the box set like this as well. The JBL GTO, Polk DB, and Hertz K series all seem like nice budget options. However, since I won't need crossovers I want to spend as much of my budget I can on drivers for maximum potential. I still certainly wouldn't rule these out though. They seem like a nice bang for the buck, which is what I'm going for ultimately.

I can vouch for this option per Thomas' recommendation. I pulled the trigger on this plug and play set. They are very good for the meager investment.

 

CDT Audio is running a sale until the end of the month. Wideband-based kits for $200, tweeter based kits for less.

 

Your midbass drivers aren’t going to be playing low enough for the qts to matter. You’d have to be running brick $hit house midbass drivers like mine to be expecting any real response near fs.

 

Interesting, can you explain this further? I do plan on crossing them at 80hz. I only have a basic understanding of ts parameters. At what point does the qts not matter exactly?

 

So all that being said, do you have a suggestion on what to get? Or do you agree with the SB Acoustics suggestion?

 

Sb acoustics are fantastic, that being said

If you're upfiring from the dash into the windshield I'd highly suggest a woofer and a wideband driver that will fit. If you can fit 2.5-3.5 inch full range it can work very well.

Edit: also like thomas' idea of using what you have and making it work. Both those driver's would work well but the scans are definitely nicer.

The qts is a bit low for my liking on the two drivers above, I’d be looking at the sb17mfc for door mounting, the cone is mineral filled polypropylene so waterproof and the qts is a bit higher than the others 👍🏼

 

When I ran the RS180 and other similar drivers 2-way (limited by off-axis install in the doors), the most inexpensive but highly effective tweets at that time were Dayton Classic silk which I ran in the dash corners, behind stock grilles, and firing straight up. These are large format but fit in many dash locations where a 3.5-4" nestle. They can take an impressively low crossover point that really helps with upper vocals being planted on the dash or above.

I used this tweeter in a pod on my pillar for a few months. It was the most detailed yet smooth tweeter I ever heard. I had to ditch the idea because they looked hideous and blocked my view. I plan to make some bookshelves with them some day.

 

Those SB acoustic mids are probably the best you'll get in that price range and then some. For the performance it's well worth it imo

 

If I go with one of the SB Acoustics mids, I'll be able to fit this SB tweeter in price range wise. The off axis graph looks nice. What do you guys think of this one and will it pair well with the SB mid?

Could you not fit a 3 inch midrange in that spot? Mayne surface mount the tweeter.

 

She's a biggun.. lol

If $60 makes that big of a difference, I would just wait until you have the funds. Do it once and do it right.

I believe that QTS used to matter when people were using passive crossovers and did not know what their crossover point was exactly because they were using a dial on an amplifier...and they had no EQ... nowadays with a DSP using high pass and EQ.. I personally do not believe QTS matters as long as the driver's FS is maybe 50hz or less...and you have a decent amount of linear excursion. if you have a QTS of 0.3 and a FS of 75hz.. then you might have a problem.. but you can model these in winisd.. as long as the driver has a decent amount of linear excursion and you have a DSP I disagree that the low QTS would be of a concern. I do not think it would change much of anything since all if affects is the slope of the low end rolloff and your high pass will be higher than the slope so it will be rendered pointless.

 

my #1 choice would be Vifa NE180W-04 - you can get them on AliExpress for $90 each. They have more linear throw than an Audiofrog GB60 which is pretty insane.. just keep in mind they are a little oversized (actually about 7" not 6.5") and quite deep. (home audio driver)

If that sounds too extreme for you then diy audio Anarchy 7" if you are running a 3 way.. or Dayton Reference..

If you are using a DSP.. you are going to get way better performance out of raw drivers than a car audio set unless you are prepared to drop more $$

 

Another vote for SB Acoustic drivers , I have SB17MFC35-4 and SB29RDNC-C000-4 in my car crossed at 2khz 24db LR driven by 150wrms and they can really go loud but remain crystal clear , they provide low distortion high quality sound , I personally think they are at the top of the list for bang for buck raw drivers.

 

These are not only budget speakers but will rival a lot of top notch drivers. I use Audiofrog now and they are better but at ten times the cost. Are they ten times better? Hell no. For home speakers they survived in my doors for close to 10 years in three different cars. They sound better IMO to AF but can't compare in power handling, except that SB29 tweeter. It can handle a boatload of power.

 

Alright, so since the consensus does seem to be leaning towards SB, I have chosen these two drivers since they fit my budget perfectly. Give me your thoughts on this setup. The SB19 tweeter looks really solid. Do you guys think it would truly be worth it spend twice the money on the SB21s?

My personal opinion here. (Shocking, this is a forum right?) The sb19 isn't gonna offer as much of an improvement as the sb29. The sb29 allows a lower crossover and is just a great tweeter. That being said.

Why not try the sb woofers with your bc25's? The 25 series of tweeters are very solid and have homes in nice speakers. The differences between the sb19 and them I think would be marginal.

If you can stretch the budget to the SB29RDNC it's a much better tweeter , higher power handling with a smaller profile making install easier , highly recommended but the SB19ST is ok if that's all your budget will allow.

 

Not to mention lower distortion from the ring domes. I've run both, it's definitely noticeable.

 

I've run the sb26 dome and sb29 ring dome that is. The 29 was the clear winner. Running one now in center (nvx xsptw).

The sb21 is a new smaller variant of the sb29 which should be easier to install imo, no experience with that one.

Fwiw, I would do the sb29 if you can fit it and are ok with the price. Excellent tweeter and a flat out bargain compared to tweeters 2-3x the price.

I only recommended the 21 because it's a bit cheaper and smaller with most of the same goodies.

 

if you want a tweeter that is cheap and kicks a$$..and do not care about large physical size.. these are two phenomenal options.. not small.. but the DX25 is one of my all time favorite tweeters at any price point.... its just huge

This post didn't get the attention it deserved.

 

So in response to the above and everyone else in the thread, the BRZ comes with a 3.5" and 3/4" in the dash, so I have plenty of room to work with when it comes to a tweeter. I'm just going to put it in the 3.5" spot with an adapter I already have. The ultimate goal here is not really to have an SQ award winning setup, but just a nice improvement over stock, which is pretty trash tbh. The door woofers aren't band, but I figure if I'm upgrading everything else, I might as well do that too.

I do plan on adding a sub. I currently have 600w @2ohms on tap for it and a Sundown e8 in a ported box, but I will be looking to downsize. That however it not imperative at the moment. That decision will come later.

As far as the install goes, I will be using the stock locations not just for an OEM look, but because I don't live in the greatest city for theft, so I don't want any obvious tweeter pods or anything like that giving people ideas.

My amps are both Precision Power, a 4 channel and a mono amp. My DSP is the Dayton Audio 408. I will most likely be using the high level inputs that go to the stock amp for signal. I have a re-pinned harness I made a few years ago that is plug n play. I'm currently using this method in my Mazda 3 and have been happy with the sound signal-wise.

 

Widebands...

 

Last question, does it matter with the SB Acoustics tweeters whether or not I choose the neo or non-neo versions? I have the room to go non-neo (plus they're generally cheaper), just wondering if that will affect the sound at all?
