It should be noted that midbass is defined as 40-80 Hz. The OPs desired range us upperbass up well into the midrange,

Dave,

It should be noted that "midbass", by definition, requires four ranges:
Bass (AKA Low), Midbass (AKA Low-mid), High-mid, High, each covering 2.5 octaves.
A single octave (as you suggested) is not an integer of the human 10 (+) octave hearing range when divided by four.

If we equally divide four ranges covering the 10(+) octave audible frequency range into the 32 ISO 1/3 octave points from 16 Hz to 20kHz, we can define the frequency ranges covered in each:
Bass is 16-80 Hz (8 ISO bands)
Midbass is 100-500 Hz (8 ISO bands)
High-mid is 630-3.15 kHz (8 ISO bands)
High is 4kHz to 20kHz kHz (8 ISO bands)

The OP's desired range of 100-500 Hz exactly fits the usual definition of "midbass", and since it would require a subwoofer below, does not by definition fit in the subwoofer forum.
The multiway forum currently has several midbass horn designs already under discussion that cover the range the OP is interested in.

Art,

This is the set of conventions i have used for a long time:

20-40 low bass
40-80 midbass
80-160 upper bass
160-320 lower mids
320-640 mids
640-1.25k mids
1.25k-2.5k upper mids
2.5k-5k lower treble
5k-10k treble
10k-20k upper treble
