I've build a pair of unity horns, with the Celestion tf0410 and bms4550. The bass is handles from 300 down by a H frame with a Eminence alpha 15. It actually sounds great, but I'm kind of missing just a few more notes down from the horn actually. That made me thing about maybe using other mid driver for the horn.

ofcourse the horns then need to be in a box which for me isn't really a problem.

Any suggestions?

you want the mids on the horn to play lower?
well, that driver you linked looks like it could help with that. As you noted you will need to enclose it to get that extension.

I was playing the 4 Faital Pro 4FE35's down to 200 Hz in my Synergies until I decided it integrated with the room better crossed over at 300 hz so its definitely feasible using something with a little more Xmax than the typical sealed back mid.

TF0410 and BMS4550 is a good choice, that will cover 250Hz-20Khz nicely.

Eminence Alpha 15 is a relatively cheap driver and it's inductance might be limiting you. What do the measurements look like?

Just for my own information when using the TPL-200 where is the starting acoustic point to measure for this driver?

I am trying to figure how high can it be run with the Celestion TF0414 closed back mids.I am used to finding exit angles and what not for CD's but I am using the TPL so its new to me.

The measurement looks like this, I crossed the mids at 300 but maybe they can go a bit lower.

Quite happy with it. Must say that there's a lot of eq'ing going on, but I really like how they sound, I'll try crossing the mids at 250 today and see if I like it.

I just really like the unity sound an hoped I could get that same sound a bit lower.

Nice response but where/what distance was the measurement taken?

Your XO to the separate woofer will affect the response at the LP, where the room intrudes. Assuming the woofer is mounted below the horn, then the lower you XO, the more floor bounce you will see from what comes out of the horn. Move the XO up and you will get less floor reflection but perhaps more sidewall reflection.

I did build the horn from X with 2x 6 inch bass and a FRM8 wideband from visaton and a cheap compression driver with a K-tube. FRM8M who can maybe also be used, is stronger but has rubber suround, I did hear that this is not so good for this kind of horns.

But the synergy horns I do like also, and ask myself can these be small for living room because most are quite big.

I've heard the Lambda Unity and Danley SH50 side by side. The larger waveguide of the SH50 definitely makes a difference.
