Hi Nesha,
You've asked a very difficult question. This driver is designed to be used with amplified musical instruments. The Musicians are quite often seeking a certain "sound or tone" that may or may not have anything in common with speakers intended to re-produce the recorded sound.
I'm certainly not an expert, but I would be somewhat reluctant to use speakers intended to "produce" music, instead of "re-producing" the recorded music without being able to hear them for myself before buying them!
I hope this helps, although there are several people on AK that are far more qualified to answer this than myself.
Best Regards,

This is quite interesting, although it's a bit more than what I am currently aiming at! That doesn't mean I don't want to see it!
Sometimes I wish I'd been born rich, instead of so darn good looking!
(I know someone is probably going to make some wise-a$$ remark to ruin my whole day!)

Good News!
One of the woofers I mentioned earlier this week "is" the same as the "single" one that Dave Rosgaard previously measured (specs already posted on this thread) !!!
Hurray!! I hope to have Dave (or someone) measure the other 2 pairs of 18 inch woofers! This guy has been so generous with his time that's it's unbelievable, especially when you consider he's putting up with me! 😱
Things are.....hopefully....back on track and moving forward once again, at least as much as they ever do around here!
Best Regards,
Terry
Just an interim note, I'll be working on these again very soon...I hope!
I will be receiving several new drivers to test soon, they're upper bass/ midrange drivers that have become available. I also have dragged out a couple of inexpensive Compression Drivers that I have, as well as several "bullet tweeters" that I need to measure to find out if they're usable...
A number of different aspects of this project should begin moving ahead very soon. I'm starting to become as excited as my Grandkids become on Christmas Eve!

Hey Terry,
Sounds like a fun project. Cost no object projects are not as fun anyway... 🙂
I had a pair of TF1020, great drivers for the price, especially since I bought them back when they were 40$ or so over at McKenzie recone. Working out a crossover around 2kHz for them had me use a Zobel in the end, the response being nothing like that of the network, despite being in a linear region for the driver. It worked much better this way.
I'll add this since pro midrange drivers are being talked about here, I sort of bought two Faital Pro 6FE100 on a whim, I'll see what they can do. Might use them in some kind of BVR or other enclosure with some gain, along with my DIY Tractrix 700Hz petal horn and Emilar EC175, or my Transylvania Power Company ''The Tube''.

I need to start experimenting with some of these things. I've been pretty slow the last few years, but hopefully that's behind me now, so I'll start gearing up a bit. I really want to try my hand with a copy or adaptation of "The Tube" among other things. This stuff is a lot of fun once you get off your rear, which is exactly what I'm starting to do....finally!

Just about the easiest and quickest horn/waveguide to kludge up at home! The below horns were way, much, more work despite the crummy looks of them!
An externally hosted image should be here but it was not working when we last tested it.

IG,
I remember your horns! Those look pretty good to me despite your modesty! Now that you've had a chance to listen to them for a while, how do they sound to you?
Best Regards,

Precisely cutting each segment (all 22 by hand and eye - didn't occur to make a template, not that I would not have wasted a bunch of time there as well...) and the whole assembly was a bit of a pain, but I still like the ratty look in the end. It's fiberglass tape and a whole lot of PVA glue BTW, spray painted hunter green. The interior is still bare paper, save for PVA in the seams. They are not ringy and produce a plasticky thud when struck, fast decay.
I used Emilar EC-175 on them, miniDSP crossover 4th order around 800Hz, it sounded pretty good. Distortion was rising fast below this. I suppose 1400Hz would be a saner Xo point for high-SPL use. I'll probably try them passively on top of that Faital 6FE100 in a BVR or maybe a Karlsonator 6, something with gain to keep sensitivity on the high side, as far as that goes with a 6.5'' mind you. It's hard to talk about them in absolute terms, but relative to my QSC waveguides, quite a different beast. In-room character was the most obvious, as it goes from ''spraying'' everywhere at 800Hz to beaming in the upper kHz's. Sound was nonetheless smooth and pleasant.
FWIW, I also setup the Emilar drivers on my QSC waveguides for a while and miniDSP'ed them to pretty much match what BMS 4550 does on there, meshing just as well with TD15M beneath. I'm not sure I would have noticed if someone else had made the swap without me knowing about it. 🙂

BMS 4550 pictured here, but I only did a few measurements, no listening IIRC:

I kept a 1" hardwood dowel in the throat when the PVA was curing, to keep it neatly circular. They fit the CD exits quite nicely. I think the angle is a fair match as well for the EC175. Simply mounted on a piece of plywood, epoxy'ed on there.
Here is the 0° and 30° response:

The 4th order 800Hz high-pass is active above, but not the correction for the broad 2kHz-7kHz hump I implemented when running these.
