Thank you NosValves, I definitely need an integrated or a receiver amp. At this time there are these vintage components for sale near my town: Fisher 400 (receiver), Fisher KX-100, Scott 299A, Leak Stereo 20 (with its pre Leak Varislope), Fisher X-100, Scott D99 (two mono power amps). What can I buy?

I listen moderately loud and I would a full body sound (preferably on the warm side than bright). My music is small jazz ensemble, acoustic and vocal.

I would know if the Scott 299 amps have a good bass for my Corns. What the sweetest of the four models (a,b,c, or d)?

I have selected these list of vintage amps for my new (1984) Cornwalls: HK Citation II, Eico HF-81 or Scott 299d, Fisher SA-100 . The HK is more expensive than the others. The only thing I want is a sweet (warm) sound. What's your preference?

Today I have modified only one Cornwall like a Cornscala: - K55-V (spring terminal) with Cobraflex horn - Type B network modified only with the 7uf cap (I mod a Type E for this) Surprisingly the stock Cornwall (with the B3 and K53-K) sounds better. I have another pair of Cornscala that use a midrange-tweeter section like the AK2 and them sound better than the modified Cornwall. A few time ago I have sold a pair of Khorn with the AA network and now I stay with an AK2 Khorn. All that seem indicate that, for my taste, I prefer better the era of AK2, AK3 or B2- B3 than the A, AA (in Khorn) or B (in Cornwall). So, I'll try a modified pair of B3 (without the 2.5mH inductor in the midrange and with the known 7uf cap) with the K55-V. I think that them will sound better than the modified B.

I use the Brimar (rectifier tube) in my Golden Tube Audio SE-300B and it is the best rectifier tube I have ever heard.

BS, I hear the K55-M in my Khorn (with K400). The K53 is in the Cornwall. Bob, if the best Cornwalls are with the B2 + K55-V + K77 (alnico), I can swap the components from my Heresys (building a B2) and compare the two combos.

Yes Bob, I would try the K55-M. Can I modify only the Midrange section of the B3 to convert it like the B2? Don't forget that I have the K55-M and the K77-M (not the alnico models). With these drivers is preferable the stock B2 network or a modified B3?

Ok. I'll stay with this combination for now but I know the sound of the K55 and I think the K53 sounds a bit different (at the first impression the male and female voices seem less deep - with less body - on the K53).

Hey Bob, is the K-600/K55 a best combo than mine?

How can I insert a pic in my post?

Hi Bob, my drivers are the K53-K and are bolted on the plastic horn. Is this a good combo? I have the K55s to replace them but not the horns (K-600?).

Is the MC225 a good choice?

I have bought them. Beautiful sound. My question is: are the K55s better than K53s? Who knows the differences between the two? What McIntosh is preferable? Lorenzo.

Finally I have found a good pair of 1984's Corns in Italy at a good price for my Country (euros 1,200.00). I have seen that the components inside are: K33-E, K53-K with plastic horn, the square K77-M and the B3 network; the back panel is removable. The tag reports: CBLS (CBL) serial 8445449. The grilles have a gold color. Now my question to the experts is: must I change the squawker with the K55-M and metal horn or is preferable what I have? What the best amp for these speakers? SET 2A3, 300B or PP? Many thanks. Lorenzo.

Paul, I have noticed no improvements to change the AK2 with the AK3. Now I have the AK2 in my system and I am very happy with them. Lorenzo.

You have done a very good work and looks fine. What is the size of the port?

Thanks TheEar, I'll contact DrWho for the cabinet.

Because of the high shipping costs to Italy, I would know if I can build a good cabinet for a single JL 13W7 that I can buy from ebay: http://cgi.ebay.it/JL-Audio-13W7-13-5-Subwoofer-HUGE-W7-HIGH-END-SUB-2004_W0QQitemZ250049786416QQihZ015QQcategoryZ18805QQssPageNameZWDVWQQrdZ1QQcmdZViewItem Who have a good plan? And what amp I have to use : can I use my DT-300 (RCM Akustik - Detonation)? I would use it for the Khorn. The Ear, I know you like the JL sub; can you help me? Thanks. Lorenzo

Ok, I know the problem to find a good sub for the Khorn; but my question was: is the RW-12 in the same league of the Vented Shiva?

No, I use the Shiva for the Home theater (with the Heresy I) and now I want to buy the RW-12 to use it with my Khorn (considering the fact that I listen to a low level sound - no loud). I have used the EBS Shiva project (142 .5 liter - 5 cubic foot net) and the dimensions are: a cube of 22.5" for side. The port is 4.65" large and 18.10" long. While the amp was a 250 Watts from Parts Express. If the RW-12 is as good as the Shiva I'll buy it because my DIY project was good (at my usual volume sound) for the Khorn.

I have built the Shiva vented project (142,5 l.) two years ago (I have paid about 550.00 euro with the shipping costs from USA) and now I can buy the RW-12 new at a fantastic price (euro 350.00) from Germany. Now I would Know if the RW-12 is in the same league of my DIY project of the Shiva ( I have tuned my Shiva to 20 Hz - is this a good value?). Many thanks. Lorenzo.

So, if I re-insert the 47uf capacitor I can use this configuration without to change anything (in the woofer section)? Is that correct? Thanks to Bob for this scheme of the TH-SR-2 crossover (naturally I have modified the mid-high section to obtain the Type E).

I have built a pair of Heresy (K22-K55V-K77) and have used a modified TH-SR-2 crossovers and now the only difference respect the type E is the inductor value (4mh instead of 2,5mh). I would know if there are problems using this different value. Many thanks. Lorenzo.

Who knows if the front panel (of the bass bin) in the Khorn is removable? I need to transport it for re-paint and I don't want to carry the entire bass bin. Lorenzo.
