Dayton Audio RST28F-4 W/ SEOS Wave Guide.

[PWR RYD]

A 6.2 uF or a 6.8 uF series capacitor? Just to be clear!

[xmax]

The first set of curves is a 6.8uf AND 1600hz active filter, the second set is a 6.2uf in series,
with no other active filtering.

[xmax]

The RS and RST (W/ SEOS-8 WG, modded on the RST) with a 6.8uf cap AND 1600hz LR4 active filter.
Pay no attention to the distortion the THD measurement was compromised.

[xmax]

Blue=RST with a LR4 @ 1.6K.
Red=RST with 6.2uf (only, no active filtering)
With the SEOS-8 on a 19x19 baffle.

The Green trace is a Satori TW29R with NO waveguide and active LR4 @ 1.6Khz.

Exactly, and testing in a standard flat baffle.

I'm interested, having thought for some time that midrange drivers in WGs offer benefits, particulary if paired with tweeters in guides that are carefully integrated with the midrange drivers in guides. There are challenges developing and producing a baffle shape that incorporates both. However, in my experience, the effort is worthwhile.

I look forward to reading about your efforts and results.

xmax You are the man! I was just wondering if anyone had successfully crossed over as low as 1600hz with this tweeter. That is very impressive to be able to crossover that low with an LR4.
