I have built many speakers during the last 15 years however one project I have never completed. 10 years ago it started out as an bookshelf speaker with the Seas Excel W17E001 and Seas Excel T25CF001. Then I added a stereo sub/bass-woofer to the system via active crossovers. First I used VIFA PL26 10" drivers. I later switch these with a pair of Seas Excel W26FX001.
After at least 4 complete redesigns of the passive crossover for the top speaker I switch the tweeter with a FOUNTEK NeoCD3.0 ribbon tweeter and tried several different crossover designs for this setup. Then I switched the tweeter again to Scan Speak 6600 Air Circ tweeter. This tweeter I really like. And now I have used a crossover design with steep filters and low crossover point (about 2kHz) to the W17 woofer. However the W17 driver has some nasty 3rd order harmonic distortion at about 1700hz and going to low with the SS 6600 does not sound good in my ears.
The reason why I have kept this speaker for so long is that it sounds good. It is for sure my best speaker. However I am not completly satisfied and the search for the perfect sound is one of the things this hobby is about.
So now I have desided to redesign this speaker with a new enclosure and a new mid range driver. So I plan to use the SS 6600 and the Seas Excel W26 10" woofer. I use an infinite baffle sub below 50 Hz.
The obvios choice for a mid range unit is of cours Seas Excel W12 or W15 however other alterantives I have been looking at are ATC SM75-150(S) and PHL 1120. I plan to use the driver in a closed or ported box.
Any suggestions?
