This tweeter is super!

[Poultrygeist]

Ajani,

Unlike 99% of the speakers discussed on this forum there are no passive crossovers in this system. The 15 inch full range bass drivers are powered by Dayton/Emo monoblocks which have active crossover controls that I set at 80hz. The middle Tang Bands are driven by Paramour 2a3 monoblocks and they run full range. The horn super tweeters have two small caps that filter out all but the very high fequencies and connected in parallel, share the Paramours with the TBs. What we have here is a 3 Way that is quad amp-ed ( 6 drivers driven by 2 pair of monoblocks ). I tried driving the tweets with a Topping t-amp which worked great but I didn't feel like tieing up the t-amp when at 98db the tweets take nothing away from the Tang Bands.

Passive crossover networks are the sound destroying, power sucking, bottle necks that prevents drivers ( wide band or not ) from operating full range. Getting rid of passive crossovers in a system makes all the difference in the world. Wide banders/full rangers like all other speakers are a compromise but they do produce a superior frequency range vs purpose built drivers.

We can achieve good bass from large full range box speakers but OB's are another story. Open baffle speakers are known for their "live dipole sound" but like planers they are bass shy. The large 15 inch bass drivers produce more realistic bass than I've ever heard from a sub.

To some on this forum these Open Baffle 3 ways may appear crude but I'd put them up against anything out there. I've never heard a commercial speaker at any price sound like these. My Zu's have been relegated to HT duty as the OB 3 ways now rule the 2 channel roost.
