Seas fa22rcz vs. Tb w8-2145 - Page 2

I'm not an expert on phase plugs, so i can't tell. But i know it's not an issue from hearing it. Someone with more knowledge can probally explain why.

just filling in the void (cavity) which would be under a dust cap helps so imo a short plug with a flat end is OK. I dread the proliferation/fad of car speakers and whatever which have "bullet" plugs as have a cheap Boss 10" with one. It was around 20 bucks and would have been about as good as a Nirvana other than a plastic ring at the end of the former causing some funky stuff.

The SEAS sounds warmer than the TB. The TB is faster with better transient response and sounds more agile and open but also dry and more analytical with the tendency to get nasal with some records like Fleetwood Mac Rumours. The SEAS has more creamy mids and fuller upper bass.

Well, it has less climb (weaker magnet), and the 2145 has a nice lift past say 4.5khz, where i add boost anyway. To me, add some bass boost, and freq response has the shape i like.

The 1772 is brighter, not mellower, and only fit for backloaded horns. And i don't like it. If you want an other of the TB 8" fullrange drivers better look at the 1808 that is slightly better, but a lot more expensive.

On the 1772, bob brines, including baffle step, used about 8db of "fixing".

Larryspkr uses 8db baffle step in his mltl as well.

Tang Band W8-1772 Impressions.

I believe fern & roby's "Raven" (using an exotic f22) uses a 2" port, not sure where they tune.

Given that the port is a little of a break compared to a subwoofer's air blasting out the port, could someone compute 3.2ft3 tuned to around 35hz for a 2" port ? or even 40hz also ?

I have both of these drivers, had them in various cabinets and tried really hard to make them sound good. The W8-1772 blows them away on every level.
