Transmission line speakers!

@russ69  and All,

As I've said, I've owned a couple of different TL speakers. I enjoyed the Clements Audio RT-7 for many years, the Fried for less. However, for the last few years I've been using a pair of sealed enclosures - Infinity RS1.5s. They are a great fit in my room and sound fantastic. Better still, I only paid $264 on eBay and picked them up from the seller as I was driving through his area on a ski trip a few years ago. I love the sound of vintage Infinity speakers! I've even bought a pair of professionally re-foamed Watkins Woofers for them. Paid almost as much for the pair of woofers as I did for the pair of speakers.

Would love to have a pair of RS2.5, 4.5 or IRS, but I don't think I have enough space for them.

Many of the Salk loudspeakers are transmission line...as are the new Philharmonic Audio towers.

When executed properly, the bass will usually go pretty deep and with good tone.

Another advantage is the roll off is such that they are easy to blend with sealed subwoofers.

@oldhvymec , I used to have a pair of those WTLC's.....long ago, far away...

The only objection, which took awhile to comprehend as to Why. was the Walsh supertweet on top, often referred to as the 'ice cream cone'...

Having corresponded with the one who worked on the prototypes literally on the kitchen table when @ Infinity, they were a bit of a lark.  Inf. had an agreement with Ohm of that era to use the concept...

My biggest observation/objection is the the cone is upside down; given the height, the Walsh only came into play when you sat on the floor about 6~8' away.  And, even then, the top corners of the TL cabinet appeared to 'get in the way'....

'Space and spacing finicky', and could have used a sub.  An active xover and tri-amping  as well, not practical at the time.

Pleasant until 'pushed', then over it's head so to speak. Replaced w/ESS AMT 1B's.

One of the reasons I play with Walsh drivers, tho'....with a somewhat different approach.... ;)

Thanks for the memory lane pic....*S*

Happy Post-New Year to you 'n all y'all...

*sigh* "It's the end of the 'bot jokes as we knew them, and I feel defined..." *L*

...at least the veneer on that pair is just as bland as what was on my pair....

Arnie liked being 'cutting edge', but apparently had issues over spending for it...

"All of My 'ports' are fixed....and a good thing, too...." *L* ;)

Spouse claims I talk out of my 'stern' port, but I point out it's kinda' 'one note'...

...to which, "Precisely!" is the refrain.....;)

Your results likely vary, to some degree....
