You can also start playing with a kit (crossover included) from Madisound, Parts Express, Meniscus Audio, and all.

Yup, but once Audyssey flattens em out a bit the highs are fun. And that's what I'm looking for. Thinking something like the peerless DFM or Celestion 1446 dayton RS180P or something else. Still scouring PE for a suitable woofer in my price range

To follow in your thinking, designing from ground up with Dayton Audio ES180TiA-8 7" first ORDER and CD third order and attenuation or tweeter.

SB-Acoustics drivers have been used successfully in an 8"+1.1" two-way:
The 8" SB23NBACS45-4 woofer in a sealed 1cuft volume has -F3 ~50Hz and justs starts beaming ~1,000Hz. Use a crossover at ~1,200Hz - 1,300Hz with LR4 / LR4 circuits to the 1.1" SB29RDC-C000-4 tweeter.

Download the datasheets. Study the SPL curves around 1,200 to 1,300Hz. You will become a believer.

The $110 8" woofer has a geometrically reinforced aluminium cone for improved break-up control. The 1.1" tweeter has increased area, 0.5mm peak-to-peak linear travel, plus a low Fs=600Hz.

Drivers + crossover parts cost ~ $200.

Hi " Remy",

Have you forgotten ( or ruled-out ) DIYSG's long retired Fusion-6 "VIBE" ??

I really thought that Matt Grant did a bang-up job on that little guy.

From what I see the "VIBE" is able to fulfill all your criteria ( ultimately bass extension would be governed by box size and tuning ) .

For review ( and archiving purposes ) here are a bunch of 6 year-old screen grabs.

While the EOS-6 horn and that little dna-150 driver are NLA, there are just as capable small drivers and small waveguides available.

You might want to contact Erich to see if he still has any of these parts that he'd like to sell.

If not, the B&C ME10 horn driven by a Peerless dfm2535 compression driver would be my first choice to use in a redesign ( it's a more than capable substitute and has a nice well damped 35mm titanium diaphragm ).

FaitalPro 6Fe100-8

FWIW, I see your budget as being doable.

I might even suggest doubling the woofer count ( for the L,C,R's ) into a TMM arrangement and finding a slightly larger waveguide for use ( such as the EOS-8 or similar ).

HiFiCompass de10 on ME10 measurements has done a nice workup of measurements on this driver/horn combo.

This horn shows surprising good directivity ( down to 2.5K ).

Erich is blowing out B&C de10's ( FYI ).
