Hi,
I recently built a pair of 4-way sealed speakers with 4 mid-level Scan-Speak drivers (TMWW) and a built in Dayton Audio sub driven by two Hypex fusion amps (122+252) per speaker. The cabinet is MDF with minimal parallel walls inside, decent bracing, 3' radius curves on the front and manufacturer recommended volumes. They sound really good to me, especially the tight fast bass.
But of course you always want to see if you can do better (and I love the whole design process). So I'm wondering if I can build a different cabinet for the same drivers/amps and hear a noticeable improvement.
There aren't many things I think I can really improve but there are some:
--Move the sub from the back to the front so it is further from the back wall (7' vs 5') and firing directly at me
--elongate the woofer chambers to reduce back wave reflection
--strengthen/double or increase damping/bracing on the MDF walls
--I could buy one more midrange per speaker and go to D'Appolito configuration, possibly moving the woofers from being together by the floor to being in an WMTMW config
--move from large baffle (currently 15" including 3" radius on the sides) to narrow baffle around the MTM
--I could conceivably move to rounded walls on the sides and back but probably wouldn't (as there doesn't seem to be consensus on whether that is necessary)
Here are pictures / plans of the existing build
Does anyone have experience suggesting it is worth it, or does it really come down to the drivers/amps as long as they are in a decent enclosure (especially given I don't have an anechoic chamber to get perfect measurements)? Just looking for some views
