Hi Thanks for reading I am thinking of a stereo set up with an active sub reproducing everything under 120hz, and i'm asking for suggestions for a midrange driver to take me from 120hz up to 5khz, then crossing over with a tweeter at 5khz.
I usually crossover at 1khz, then use a mid to take me up to the 5khz tweeter, but the 1khz crossover is bothering my ears.
Is this scenario possible, or do you think asking a drive unit to go from 120hz to 5khz is too much and will result in poor sound
I haven't purchased much yet, i do have the active sub from an old build, i want to try and get the facts together before making a move

Depending on the driver. In the example below, the TB doesn't cut the midrange at all!

Just buy a pair of Triangle BR03 two way speakers. Very impressive sound and well made too. 90db / 8r sensitivty so suitable for my SE valve smp.
I will be using a Dayton Audio DSP-LF and separate amp to drive a subwoofer..

Thanks ! I don't want ready made speakers, i'd rather make my own
What do you think of the original question : if it possible for a single drive unit to reproduce audio from 120hz to 5khz and do it well, or is this too much to ask of a single driver ?
If a single driver can do this do you have any recommendations

You will have most issues with beaming. The smallest one I have tried, that will work is the Mark Audio CHR70. The sound is really good, and have ok dispersion to 5 khz. Ideally you should use a 2,5-3" midrange, but you will have trouble going down to 120 Hz.
If you only listen on-axis and you have no reflexions from hard walls or windows, then you can choose a bigger midrange.

There are hundreds of CDs that will go from 1000 hz to 17000 hz. A few will go 800 to 20000. Does your hearing even go above 17000 hz?
That unloads the woofer substantially. Example Eminence N314-T8, which is 3 db down at 1000 and 17000, 5 db down at 800 and 13 db down at 20000. 100 w AES also, so plenty of room for some volume to unload the woofer 1000-1500. I paid $190 each for them and horns were $73.
Frankly I did not get beaming with 15" woofer to 1000 hz, (1995 SP2-XT) and Peavey and JBL designed wedge shaped cabinets and elastomer fills to allow 90 deg -6 db horizontal dispersion from 15" woofer to 1800 hz. (SP2-2004). SP2-XT was -3 db 45 deg horizontal 500 hz to 16 khz. A 15" woofer allowed one cabinet to handle down - 3db to 54 hz, so I don't need to run a sub channel. Kneldsen is living in an archaic environment.

I would be looking for a tweeter that had a range from 3Khz.Many do.
You haven't said what your budget is for them. E.g. Seas Presitge DT27DCH operates from 2-25K but costs £63 ea from Falcon Acoustics.

For the mid woofer: https://www.falconacoustics.co.uk/downloads/Scanspeak/12w-4524g00.pdf
possibly paired with a Scanspeak tweeter: https://www.falconacoustics.co.uk/downloads/Scanspeak/r2604-832000.pdf
These aren't recommendation just example though I used the Seas in a pair of TDL RTLSEs and a Scanspeak in some Naim SBLs.
You will be able to find suitable drivers from Falcon, I'm sure.
Thanks ! I’d be happy with a 5”, if you can expand with suggestions
I’m not a fan of full range drivers.
Very good points. I am looking for a single drive unit to take me from 120hz to 5khz with good sound quality. From your answer do you feel that this is not possible
Look for a driver that fits the directivity pattern of the tweeter at the desired crossover frequency. At 5k that could become a challenge if you use regular dome tweeters. Also consider crossing lower, around 2-3kHz.
I have spent the best part of the day looking for drivers, unfortunatly it comes down to budget. The promising ones cost several £100's, i am more looking at the dayton audio RS series which are like £100 per driver, but i keep hearing too many negatives about the RS, not sure anything in the RS series would do well when asked to reproduce 120hz to 5khz, so i came onto this website hoping for bargains, if a driver has a high cost to sound quality ratio
Where does the need for 5 kHz come from?
What are your directivity, sensitivity and max SPL requirements?
What about a line array?
I have used visaton BG17-8 which goes from 150 to 12 khz for full range speakers. It is 2 db down at 120 hz. It only has a power rating of 40 w so not much use for parties. Response is bumpy above 10000 hz so maybe filtering off and adding a tweeter above that might be useful. Sensitivity is 93 db and - 6 db dispersion at 4000 hz is 51 deg. I paid about $40 for it.
Goodguys can't accept crossover point at 1 kz. It doesn't sound good to his ears. He would like a crossover frequency at 5 kHz. That's the limiting factor here. Personally I'm building with CD horn at the moment crossing to a 12 inch, but all this is of no interest for Goodguys since he would like a crossover point around 5 kHz. Indianajo did you even read his post, or just the headline?
Personally I think crossing at 5000 hz does not reflect reallity. Distortion and dispersion at various frequencies, plus power handling rating, determine crossover point. Even dome tweeters go way below 5000, limited by power handling capability on a pink noise signal. Whizzer cone drivers go up to 5000 and beyond but are not an ideal solution for the distortion. Whizzer cones tend to be not very powerful or sensitive.
I agree, but some people have very sensitive hearing. You simply do not answer the original question.
There are good crossovers at 1000, and garbage ones. I have excellent hearing to 14500 hz and can hear HD to at least below 0.5% on speakers. I have a Steinway piano in my music room to provide a calibration reference for those source tracks.
The least distorting speaker I have heard has a one inductor roll off on the woofer, and a series cap and parallel inductor on the tweeter. Some popular speakers as Asathor have 10 cap+inductor crossovers. Who knows what the phase performance of all that modification is. At least now there are electronic crossovers that simplify the phase coherance.
