longdrive03 Posted May 13, 2014 Share Posted May 13, 2014 Building these for a friend using the RF7 horn and driver and RF7ii woofers. Cabinet is a little wider at front, narrower in back and a little deeper than RF7ii cabinets. Braced these suckers well with 5 horizontal braces per cabinet. Just finished 6th coat of wipe on poly. Need to build grill frames and install foam and speakers take a listen. Quote Link to comment Share on other sites More sharing options...

Schu Posted May 13, 2014 Share Posted May 13, 2014 what are the curved sides made from and how thick are they? Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted May 13, 2014 Share Posted May 13, 2014 I like the front ports. I was curious as to the make up of the sides as well. Quote Link to comment Share on other sites More sharing options...
longdrive03 Posted May 13, 2014 Author Share Posted May 13, 2014 Thanks guys. I used 1/2" bendable plywood (2 layers) on the sides and wrapped it around the 5 braces and attached with PL premium adhesive (nasty stuff) and 8 million staples. I used Titebond glue between the 2 plys with some rubber open weave drawer liner. It is very hard and stiff. Then I applied the cherry veneer and 3/4" solid cherry on the top. The bendable plywood is great stuff (no kerfing involved). The sides are 1" thick and very solid. This is a lot easier than the prior 45degree angle side build I did (and won't do again!).

Heritage_Head Posted May 13, 2014 Share Posted May 13, 2014 Those look great nice job. What crossover are you going to use? Im not sure the two drivers are comparable. I think the old rf7s woofs response went higher being the xo to the horn was higher. I guess i don't know. Quote Link to comment Share on other sites More sharing options...
Deang Posted May 13, 2014 Share Posted May 13, 2014 That's the problem I alluded to in your "pro" thread in the other section of the forum. You now have what amounts to a new loudspeaker. I would try and get the internal volume and ports as close to the RF-7ii as possible. I strongly suspect that the RF-7ii and RF-7 use the same compression driver (P.Audio). If that's true, then you could use the crossover from the ii. Quote Link to comment Share on other sites More sharing options...

Heritage_Head Posted May 13, 2014 Share Posted May 13, 2014 Cant find the thread but someone was asking if they could swap to the new xo (with the lower xo to the horn). Quote Link to comment Share on other sites More sharing options...
longdrive03 Posted May 14, 2014 Author Share Posted May 14, 2014 I'm using the K-67 tweeter driver used in the RF7 and the new RF7ii woofers. So far I'm playing with the RF7 crossover schemdatic fromthe forum using Dean G's suggested Mills resistor on the cross leg in the tweeter circuit. I tested the woofers on the woofer tester and a friend ran specs in bass box and I got 3.7" dual flared end ports with internal volumei right at 4cf. I haven't installed speakers yet since xovers aren't finished but they sure sound good in open air with just one woofer hooked up. I think the K-67 is the Paudio BMD440. Not sure who makes the K-701-G driver used in the RF7ii but it looks larger in a photo on the forum about removing the xover in an RF7ii. . They have different klipsch model numbers and the 701 is about half the price of the 67. From reading on the forum I understood that the RF7ii switched to 1200HZ xover from 2200hz in the RF7 because of a larger horn that would handle the1200 hz xover. Yes, I applied the cherry aircraft grade veneer over the two layers of 1/2" bendable ply then attached solid cherry wood trim on fronts and top. Any nput or help with crossover would be welcome.

longdrive03 Posted May 19, 2014 Author Share Posted May 19, 2014 Thanks Dean. I didn't have anything to compared the tweeter section on this with your resistor mod to a non-resistor mod but it is very clear and precise. No shrillness. The woofers are very capable and provide great impact. So far everyone who has heard them are very impressed. Quote Link to comment Share on other sites More sharing options...
