Cornwall I Mods - 1 More?

I have a pair of 1979 Cornwalls that came with the B network. I have since replaced the network with an ALK Klipsch B Series Replacement crossover and swapped out the original K77 tweeters for SMAHLs. I'm now contemplating an upgrade of the K33 B woofers to Crites CW1526. From all I've read, there should be some improvement on the low end, but would like to hear specifically about this woofer in the Cornwall cabinet. I've recently moved into a new house and the room is drastically different acoustically. It has a high vaulted ceiling, hardwood floor over concrete and leather sofa(not so soft). In other words, mostly hard surfaces, the old homestead had a big soft cloth covered sofa and wall to wall carpeting. It seems that in the new environment bass is now a bit lacking from my Cornwalls.

Would this be a worthwhile upgrade or are there better alternatives? Please don't say just get a sub-woofer, that option just isn't in the cards.

If you get a Crites woofer, the stamped frame one is better for the Cornwall.

However, what is wrong with the K33's you have now? They are good woofers. The CW was designed specifically for that woofer.

Steve , I have 84 Corns & purchased, ALK Universal crossover & Crites woofer to mod my Corns. I found that the original woofers hold up better in the baseline. YMMV
 
If you really want to improve Cornwalls replace the mid horn, it really holds that speaker back! Lots of good choices out there, I am lucky to have scored a couple of pairs of wooden tractrix horns that fit K55 drivers (can't remember who made them). The Crites cast frame woofers are nice however.
And yes, fix your room first.

What? No Quarter Pie photos, Mr. Quarter Pie KING? LOL. Welcome to the Klipsch Korner you Horn Driver, you.
 
You have some bass cancellation going on and room treatment/EQ/PEQ is necessary.

Room correction is necessary more times than you think even if everything sounds "good" to you. I've been experimenting with home theater receivers (mainly Pioneer) with room correction such as MCACC and it has made a huge difference in correcting standing waves, group delay and PEQ/EQ. There are a host of methods to use for room correction and you should check them out.

And when you do, a single supplied microphone reading at your nose in the Main Listening Position should be all you need. I spent several years doing more and more Mike readings with Onkyos/Audyssey readings as my receivers had better features, and things got worse and worse. Keeping it simple still applies, however you can't fix ACOUSTIC issues Electronically. Room EQ is only icing on the cake, not the Cake itself. You have to bake that Acoustic Cake first.

This.
I thought my system sounds really good, then I did some tuning in my room with diffusion and absorption panels and things improved by an order of magnitude. I've repeatedly read about the importance of tuning one's room, but apart from a recording studio I built in the 90's, it's not really something I'd ever done or found the need to do. However, now that I've done it in a room that sounded good in the first place, I'll join the chorus in saying that it's something that you should do first, not last.

Thank you everyone, it looks like I really need to get better educated with my Umik and REW along with whatever I can alter in the room (not much).

Out of curiosity, why would that be?

It simulates differently. I used to own them both. The one with the cast frame is better for the Khorn, but they are so close and more dependent on your network and midhorn response.

Room Correction can involve the placement of absorbent material/items. Extreme cases involve altering the physical room dimensions.

Aaahh . . . Good to know coming from one who's been there, etc.

Thank you!
