Upgrading an L-200

[witoman]

Thanks very much for all of the help. I'm still learning.

Would I lessen the inherent compromise of using a 136A woofer in the L-200 (with one of two ports covered) using the LX-16 1200 Hz crossover point by using a 2235H woofer instead?

The 2235H spec sheet says that the highest recommended crossover frequency is 1000 Hz. The FR graph looks like it is + or - 2 dB out to 1800 Hz or so on axis.

Compare the curves. 2235H turns to poop at 1 kHz, whereas 2231's good to 2 kHz, if they are to be believed.

If you perceive 1200 Hz to be a problem, move down to 800 Hz as first option....

Personally I would not try to use a 15" woofer up to 1200Hz.


It has a large, rather heavy cone. Details will be lost compared to both a compression driver and a smaller cone driver.

Forget the LX16. Throw it in the trash. Build a pair of N200B filters, charge couple them and enjoy. Zilch provided you with the N200B schematic earlier in this thread.

Wrong!!!! I got $150 for a pair on eBay... sell those dogs!

I was taught NOT to take advantage of the suckers born every minute. I'd throw them in the trash.

No doubt.

I'm selling the LE15B's right now. See Marketplace.

Excellent!

Looks like someone has met your reserve too.
