  1. Justin, that's a nice looking amplifier. Have you thought about having one available as a roadshow unit? I am sure there are many that are interested. Single ended tetrodes and pentodes sound very nice. I have been preferring them to SE triodes as of late.

  2. I would be exhaustive for EV to build a FIR library for any possible permutation. Simply use the Remez Exchange Algorithm to find the coefficients, but be warned... chose your average weighting factor carefully for a relevant exponential average. the benefits of the FIR device should make any trouble getting the settings worth while.

    This may be helpful.

  3. I believe that I heard that one in Hope - it is a better driver, but I have to say that it doesn't match the TADs, IMHO. YMMV.

    Of course they don't Chris, but you can order them for an additional $125.00 each on a 402 while the 4002's are $2000.00 ea. and very difficult to get at the moment. i would buy TAD's today if anyone stocked them.

  4. reverse that. the 1133 has a phse plug which takes it to 20khz. the 1132 has a snout which does wonders for the mid range, but limits the high end to 12khz.

    Check your facts, don't want people to get bad advise, if people bought the 1133 for a two way jubilee, they would not be happy unless they could not hear past 10K. The K-1133 is indeed a mid driver and the 1132 a high frequency driver.

  5. The K-1133 is a mid driver, the K-1132 is a high frequency driver.

    I have found on my jubilees that the B&C D-75 driver which is used on many klipsch pro speakers bests the K-69 by quite bit. Also, there are active settings around to support the B&C driver with the 402 horn and jubilee bottom. There are no settings for the 510 when used with the B&C driver, but the 402 settings should be close enough to start with.

  6. same k-510/k-69 others are suing on two way versions. I think you are talking k-69 in general since the k-402 was intended to be used with an 1133 on top of the jub bass bin.

    The K-69 is not the problem, it will keep up, the K-70 will not. I believe there is wording on the crossover that points to this as well.

    For any home use, the k-69 with the 510 will hold up just fine crossed at 400 with the active settings. I would probably stay away from the crossover point with a passive.

  7. the real winner is the 415-quad which comes in at -10db at 26hz. next runner up is the 904-lh which comes in at -10db at 32hz, third runner up is the jubilee which comes in at -10db at 34hz, followed by the mwm which comes in at -10db at 35hz.

    mwm's really are not very deep performers, they are just loud ones. mwm's are all about the stick shift game...my stick shift is bigger than your stick shift...bigger is better is deeply wired into our brains..

    Surprisingly, in listening it is quite different. The 415 has about the same extension as the jubilee and very similar character, possibly a slight bit more weight to its bass. The jubilee bests the 904 bass bin by a decent margin in extension and weight to its sound. There was not a MWM bass bin on hand, but I trusts Mark's take on that point.

  8. I would suggest you buy 402's or 510's, which ever you will run with the jubilee bass bins and make Jubscalas for now. there is no reason to waste money on the 942 bass bins if you plan on getting jubilees later. The 402 or 510 will get you most of the way to where you need to go.
