I currently have two nice looking tower speakers, current drivers are tuned very easy listening and generally a decent sound, however it's not as technically capable as some other speakers; bass has a warm bump in the upper, the easy listening tune is just enough too recessed in mids that it doesn't have the satisfying ear fill. Deep bass is less than expected from box size and can hear harmonic overtones.
Woofers - Audax aerogel ap170Z0
Tweeter - Vifa bc25sc55
Tossing up driver choices for fun DIY project. Doesn't need to be perfect ideal as I already have things like that. Purifi doesn't fit and would be out of scope to enlarge cutout, likely plus tweeter too small for directivity match, or having only 1 Purifi because other hole has waveguide tweeter seems a waste of box size?
For fun I have considered drop in sized drivers.
Option 1 : 2x Mark Audio Pluvia 11 per box, in 2.5 way config. Maybe with option for full range top driver, or shallow roll off to tweeter using switch.
Option 2 : 1x Mark Audio at top, create sealed compartment (there is holey cheese bracing throughout that I can fill for this).
1x SB Acoustics SB17 NBAC35 in lower compartment. Again with full range or tweeter option.
Option 3 : Double SB Acoustics NBAC35 sharing space and doing a 2.5 way or MTM, might look at other tweeters; maybe CSS XBL2 chopped to truncated shape, or a metal dome (I do seem to end up liking these). Crossover frequency would be interesting as you can't really fit a waveguide in existing spot.
Option 4 : Filling top woofer hole with mid-tweet module. This would be closer to ideal but may look messier; more work being a proper three way. Also have unused existing tweeter hole to deal with. Maybe put tone controls there.
Mark Audio drivers arguably look nicer. Which means it sounds better right? lol
The MA/SBA combo still has the single woofer for deep bass caveat.
2x SBA smoother and likely better deep bass.
Option 4 again with single bass woofer caveat.
I'd also be trying out filters via DSP before making passive version.
Thinking option 1 or 3 is keeping things more simple.
Real wood, nice contrasted grain, bevels with multi-faceted corners. Veneered inside too, with plenty of bracing.
Port could be modified if needed.
