Default A mini fullrange driver comparison - what should i build?

I am currently into small fullrange drivers. I want to build two small Transmission Lines for my pc.

So i compared three speakers:

1. Dayton Audio CE Series CE46P-4 1-7/8" Paper Full Range Driver
2. GRS 3FR-4 Full Range 3" Speaker Driver 4 Ohm
3. Peerless TC6WD02-04 Silver Series 2" Midrange

I simulated these drivers with Leonards Audio Transmission Line Software in different TMLs.

1. I simulated a TML with 12 cm² start and end-area and 100cm length. The predicted frequency response goes down to 80Hz. The driver is at 1/3 of the line (33cm from start).

2. I simulated a TML with 50cm² starting area decreasing to 35cm² end area. The line is 80cm long. The predicted frequency response goes down to ~85Hz. The driver is at ~1/3 of the line (28cm from start).

3. I simulated a TML with 20 cm² start and end-area with 100cm length. The predicted frequency response goes down to ~80Hz. The driver is at 1/3 of the line (33cm from start).

Does anyone here has experiences with these drivers? Which speaker would you choose?

Hi,

None of them :
The peerless needs a tweeter
The GRS has no specified response
The dayton is too small, low power, low sensitivity.

I'd use this : (seen its specs and response somewhere)
Tectonic Elements TEBM65C20F-8 3-1/2" BMR Full-Range Speaker 8 Ohm
with :
Lepai LP-2020A+ Tripath Class-T Hi-Fi Audio Mini Amplifier with Power Supply

rgds, sreten.

Don't be throwing a Cheap low grade Chinese Amp into the fray.
The Lepai is complete and utter Junk .. in my (repeated ) experiences, describing it charitably/politely .
I was convinced that my admittedly entry level Mark Audio drivers were worthless/bad performers, based on what they sounded like on several Leapis (All of which died in short order, just to add insult to injury)
Fitting a Real amp to the Mark Audio drivers was an epiphany.
Garbage in most certainly equals Garbage out.

Here's what I'd recommend (from Eu, as shipping from PE or Madisound will bleed you dry):

Peerless (Vifa) Breitbandlautsprecher TC9FD-18-08 (9 BN 119/8)
Faital PRO Breitbandlautsprecher 3FE25A

Both are cheap, tested and proven good.

This is very interesting to me as I'm about to do something similar.
I already have the vifa driver recommended by Mayuri in a small sealed box crossed over to a sub and I think it sounds great.
This system is moving so I'm going to build something new and was considering a small tl like you. I've recently acquired the hiwave driver recommended by sreten for this purpose and was looking at modelling it in something like the tabaq or lance speaker (both found on these forums).
Anyway the guy at spectrum audio (mayuri's link) seems to recommend both these drivers and stocks many more so it may be worth speaking to him. This assumes of course that you're happy to invest in more drivers ��

Because i only use this speakers as pc speakers or in quiet environments it's okay if it has low power. What do you mean with "low sensitivity"?.
