If you can handle the truncated midrange recesss, I could offer a good deal on the parts for these.
PM me if you are interested.

Btw, as for other DIY designs that have good directivity and supply decent measurements to prove, check out :

@Dennis Murphy got the new batch of crossovers and was starting to send out the kits to people on the waitlist, but apparently PE sold off most of one of the drivers to a corporate buyer, which delayed the latest AAM. You might be able to get in on the current round if you contact Dennis.

DIY because it's fun. For example, "regular" two-way speakers, where there are so many good value ready-made. Although it does not prevent you to DIY some yourself, for the mentioned reason.
You may have different needs, then you may need to tailor. For example, a subwoofer under the sofa. So it fits under your own sofa.
Tip, here we are talking about dispersion via both front and rear-firing tweeters (simultaneously). Also a little about, dipoles and omnis. Good dispersion in that thread (I know it was too simple, I could not help it).

Backwards directed , rear-firing tweeter, Snell Type E / III?
Anyone have experience with such speakers? What are the advantages and disadvantages? Grateful for response. Snell Type E / III, just to show an example of what I mean:

Wayne Parham’s PI 4s may fit the bill, they are wide (uniform) directivity bass reflex with compression driver/waveguided tweeters the plans are free, support is great, a few options on drivers. Wayne publishes measurements.

Here are tips on a good midrange driver:

Absolutely incredible.

Edit:
Two of these I built computer / desktop speakers with. Chose them mostly because of the relatively high sensitivity.

That's a great Freudian slip. It provided a little comic relief in what is otherwise an overly comical thread. It is not a Freudian slip, just a language slip. I edited it. English is not my native language.

Looks like they are available. Maybe for immediate shipping? Maybe you should do the Ricardo Montalban version.
Those sound really good... I know youtube yadayada and they are outside, but wow. *starts researching line arrays*

Line speakers have advantages and disadvantages. If you get them well done and they fit in the listening room (aesthetically and acoustically), they are probably really good.
Here DIY with such:

Another update: the 'sandwich' panels are done! As you can see in the below pictures, Green Glue has been applied between the panels (2x12mm birch plywood) There are some panels missing, they will be done a bit later The next phase will be to put together the back of the speaker, paint it (with...

I so appreciate all the suggestions. As I am new to this and have only put together flat packs I would like to construct my own enclosure for the first time. This means line arrays are probably not going to be my first enclosure build
- So hoping to build my own enclosure
- would like to experiment with a wide dispersion design
- probably a bookshelf but not against a floor stander
- Would like bass around 40hz in room (probably cross to sub at 60hz)
- don't want to spend more than $300-400 on this kit
- needs simple baffle cutout so no strange driver designs that can't be cut out with a router and jasper jig
Is this wide dispersion enough?
You can find the improved crossover in the HiVi 3.1 review thread and easily pick up the drivers at PE.

I did see this way back. Noticed the Amazon kit was gone a while back. I guess I didn't think to find the parts elsewhere. The other complication would be finding the measurements for the enclosure. Properly spacing the drivers and and cutting out the square for the tweeter. I suppose the tweeter is closed though so I just would need to make sure it could fit through and the flush mount part was cut accurately. Hmm...Is this wide dispersion enough?

I actually have one of these kits in the garage and I can measure the spacing on the baffle for you, in fact I would sell it if you were interested. These HiVi 3.1a are kind of halfway between my 2 way bookshelf speakers and my BMRs and I am not sure when I'd actually build them and find a place for them. At the same time, they are clearly a really nice kit and it is tempting to build them up.

I would be very interested in purchasing from you. It's exactly what I am interested in, as far as an inexpensive go between what I have now and an eventual BMR I would like to build.
I haven't heard much about the BMRs outside of Dennis's speaker. Could you expand a little on your observations? I thought the smaller ones might be better for mid to hi frequencies. I believe Erin measured one a couple of years ago.
I've heard several... (PE member names posted)
jhollander had his 'BMR-3L' with the 3.5". They sounded great with the right tuning and really doug deeply for a 3.5", however there was a deep and narrow response aberration in its response due to the type of driver it is. It did not seem to be audible. The mechanical damping was really impressive that it did not shoot the membrane across the room.
The following all used the same Tectonic BMR as the BMR-monitor;
4thtry built his 'Totally Flat', and those were just fantastic. He paired it with a small AMT and the Dayton LW5 woofer and won his class at MWAF that year. He also built the 'Plumbers Delight', which won the Nanotech compy for InDIYana and the integration on those was just spectacular.
paulk built his 'Balmora' 3-ways, and they did not impress me. It might be that he used the minimum volume 'required' for the mid, or the fact that I don't like the SB19 in general either, but they were just bland by comparison to a lot of his other projects.
I think it really comes down to the supporting drivers and finesse of the designer. The 2" mid as it stands is not the most resolving in detail, but it tends to be pretty smooth and has great off-axis measurements and responses.
