Hello everyone,
The conjuncture and poor built of vintage KEF cabinets lead me to owning quite a few KEF drivers:
- 2 pairs of T27 SP1032 tweeters (one matched)
- 1 pair of B110 SP1003 mid-woofers
- 1 pair of B200 SP1039 mid-woofers
- 2 pairs of B139 SP1044 woofers
- 1 pair of B139 SP1042 passive radiators
Basically these represent the drivers pulled out of a pair of KEF 104 Reference and a pair of KEF Concerto speakers. Also I have the related crossovers.
My question is: do you think it would be worthy to build a 4 way speaker, based on the design of the Acoustic Research AR-9's?
I plan to use one pair of T27 SP1032 tweeters for highs, the B110 SP1003 for the upper mid range, the B200 SP1039 for the lower mid range and one pair of B139 SP1044 along with the passive radiators B139 SP1042 for bass (so the impedance will be 8ohms). The bass units will be positioned on the sides of the speaker box similar to the design of the AR-9's.
Crossover points will be at 400Hz, 1000Hz and 3500Hz.
Regarding the speaker size, positioning of drivers on baffle and crossover design, a specialized company will be seeked as I do not own the technical equipment, nor the knowledge.
So, what do you think?
Thanks in advance
